A Melaleuca with very small decussate leaves, a tree about twenty-five feet high, was growing on the scrubby ridges. Flooded-gums of most majestic size, and Casuarinas, grew along the river; in which there were many large reedy water-holes. The season must be more than usually dry, some of the largest holes containing only shallow pools, which were crowded with small fishes, seemingly gasping for rain. A Ruellia, with large white and blue flowers, adorned the grassy flats along the Suttor. The latitude of this spot was 21 degrees 26 minutes 36 seconds.

March 14.—We removed down the river about eight miles S. S. W. to good water-holes, which had been seen by my companions the day before. Here the scrub approached the river, leaving only a narrow belt of open forest, which was occasionally interrupted by low ridges of stunted silver-leaved Ironbark. Pegmatite and Porphyry (with a very few small crystals of felspar) and Gneiss? were observed in situ. On our way we passed a fine lagoon. A dry but not hot wind blew from the S. S. W.; the night and morning were bright; cumuli with sharp margins hung about after eleven o'clock.

A pelican was seen flying down the river, and two native companions and an ibis were at the water-holes. Crows, cockatoos, and ducks were frequent. From the remains of mussels about these water-holes, the natives have enjoyed many recent meals.

I sent Mr. Roper and Charley down the river, who informed me, on their return late at night, that they had found water at different distances; the farthest they reached was distant about seventeen miles, in a water-hole near the scrub; but the bed of the river was dry. As they rode, one on the right and the other on the left side of the river, a Blackfellow hailed Charley and approached him, but when he saw Mr. Roper—who crossed over upon being called—he immediately climbed a tree, and his gin, who was far advanced in pregnancy, ascended another. As Mr. Roper moved round the base of the tree, in order to look the Blackfellow in the face, and to speak with him, the latter studiously avoided looking at Mr. Roper, by shifting round and round the trunk like an iguana. At last, however, he answered to the inquiry for water, by pointing to the W. N. W. The woman also kept her face averted from the white man. Proceeding farther down the river they saw natives encamped at a water-hole, who, as soon as they became aware of the approach of the two horsemen, withdrew with the greatest haste into the scrub; the men driving the shrieking women and children before them. Upon Mr. Roper galloping after them, one athletic fellow turned round and threatened to throw his bommerang, at this sign of hostility Mr. Roper prudently retired. Kangaroo and other nets made of some plant and not of bark, koolimans, bommerangs, waddies, and a fine opossum cloak were found at the camp, but were left untouched by our companions.

March 15.—Our party moved to the water-holes, where Mr. Roper had seen the natives; the latter had removed their property, and were not afterwards heard or seen by any of us. The general course of the river was about south-west, and is joined by several scrub creeks; its bed is broad and shallow, with numerous channels, separated by bergues; and the river itself is split into several anabranches. The scrub is generally an open Vitex; a fine drooping tea-tree lines the banks of the river; Casuarina disappears; the flooded-gum is frequent, but of smaller size. The Mackenzie-bean and several other papilionaceous plants, with some new grasses, grow in it. The most interesting plant, however, is a species of Datura, from one to two feet high, which genus has not previously been observed in Australia. I also found species of Heliotropium of a most fragrant odour.

Sandstone cropped out in several places, and red quartz pebbles were very abundant in some parts of the river; the sands of its bed are so triturated that no one would ever surmise the existence of granitic rocks, at sixteen or twenty miles higher up. The whole country was flat; no hill was visible, but, towards the end of our day's journey, we crossed a few slight undulations.

During the night of the 14th, southerly winds were followed by a gale from the eastward, with scud and drizzling rain. The morning of the 15th was cloudy with a little rain; wind southerly. Early in the night, a strong east-wind with drizzling long rain set in, but cleared up at midnight. The morning of the 16th was cloudy, with a southerly wind. Our lat. was 21 degrees 39 minutes 58 seconds.

March 17.—Mr. Gilbert and Brown went forward in search of water, supposing that they would find it at a convenient distance, but were unsuccessful, and, as they had taken neither guns nor provisions, they were obliged to return. Keeping, however, a little more to the left, on their return, they came to two fine water-holes at the foot of some ironstone ridges, where they passed the night, and reached the camp the following day, having had nothing to eat for twenty-four hours. The camp was then moved to these water-holes, about nine miles off, in a due west course. Fine water-holes were passed at a short half-mile from our camp; and, after crossing the northern anabranch of the river, we again found water.

The detection of isolated water-holes in a wooded country, where there is nothing visible to indicate its presence, is quite a matter of chance. We have often unconsciously passed well-filled water-holes, at less than a hundred yards distant, whilst we were suffering severely from thirst. Our horses and bullocks never showed that instinctive faculty of detecting water, so often mentioned by other travellers; and I remember instances, in which the bullocks have remained the whole night, not fifty yards from water-holes, without finding them; and, indeed, whenever we came to small water-holes, we had to drive the cattle down to them, or they would have strayed off to find water elsewhere. On several occasions I followed their tracks, and observed they were influenced entirely by their sight when in search of it; at times attracted by a distant patch of deeper verdure, at others following down a hollow or a watercourse, but I do not recollect a single instance where they found water for themselves. The horses, however, were naturally more restless and impatient, and, when we approached a creek or a watercourse after a long journey, would descend into the bed and follow it for long distances to find water; giving great trouble to those who had to bring them back to the line of march. Whenever they saw me halt at the place where I intended to encamp, they not only quickened their pace, but often galloped towards me, well knowing that I had found water, and that they were to be relieved of their loads. In looking for water, my search was first made in the neighbourhood of hills, ridges, and ranges, which from their extent and elevation were most likely to lead me to it, either in beds of creeks, or rivers, or in water-holes, parallel to them. In an open country, there are many indications which a practised eye will readily seize: a cluster of trees of a greener foliage, hollows with luxuriant grass, eagles circling in the air, crows, cockatoos, pigeons (especially before sunset), and the call of Grallina Australis and flocks of little finches, would always attract our attention. The margins of scrubs were generally provided with chains of holes. But a flat country, openly timbered, without any break of the surface or of the forest, was by no means encouraging; and I have frequently travelled more than twenty-five miles in a straight line without obtaining my object, In coming on creeks, it required some experience in the country, to know whether to travel up or down the bed: some being well provided with water immediately at the foot of the range, and others being entirely dry at their upper part, but forming large puddled holes, lower down, in a flat country. From daily experience, we acquired a sort of instinctive feeling as to the course we should adopt, and were seldom wrong in our decisions.

The ridges, near the water-holes on which we were encamped, are composed of an igneous rock containing much iron, with which the water was impregnated to such a degree, that our tea turned quite black and inky. The natives were very numerous in these parts, and their tracks were everywhere visible. They had even followed the tracks of Mr. Gilbert's and Brown's horses of the preceding day.

The night was bright; the day cloudy, and the wind easterly. I went with Charley, in the afternoon of the 17th, to examine the extent of the scrubby country, of which Mr. Gilbert had given us so poor an account. The channel of the river became narrow and deep, with steep banks, as it enters the scrub, and there the flooded gums entirely disappeared. The scrub is about eight miles long, and from two to three miles broad, and is tolerably open. The Bricklow is here a real tree, but of stunted growth, with regularly fissured bark, like that of the Ironbark (Eucalyptus resinifera). It has long broad falcate phyllodia, whilst another species of the same size has an irregular scaly bark, with small phyllodia, but of a greyer colour than those of the common Bricklow. Both species grow promiscuously together. Where the river left the scrub, it entered into a wild water-worn box flat, and cut up into several irregular channels, lined by a dense thicket of narrow-leaved Melaleucas of stunted growth and irregular shapes. The Box-tree itself is here a different species, the bark has deeper fissures, and the young wood is very yellow. I shall distinguish it by the name of "Water-box," as it grows exclusively near creeks, or on the neighbouring flats. I first observed it at the Mackenzie; its bark strips freely, but the stem is too short and irregular to be of any use.

In passing a low hill, at the foot of which the box-flat commenced, we came on a very distinct path of the natives, which led us to a deep water-hole, covered with luxuriant grass; containing but a small quantity of water. Farther on we came to a second hole better supplied, and to a third; and at last Charley cried out, "Look there, Sir! what big water!" and a long broad sheet of water stretched in sweeps through a dense Bauhinia and Bricklow scrub, which covered its steep banks. It is a singular character of this remarkable country, that extremes so often meet; the most miserable scrub, with the open plain and fine forest land; and the most paralysing dryness, with the finest supply of water.

Swarms of ducks covered the margin of the lake; pelicans, beyond the reach of shot, floated on its bosom; land-turties plunged into its waters; and shags started from dead trees lying half immersed, as we trod the well-beaten path of the natives along its banks. The inhabitants of this part of the country, doubtless, visit this spot frequently, judging from the numerous heaps of muscle-shells. This fine piece of water, probably in the main channel of the Suttor, is three miles long, and is surrounded with one mass of scrub, which opens a little at its north-western extremity.

March 10.—I continued my ride, ten or twelve miles down the river; the scrub continued, but the immediate neighbourhood became a little more open; several trees were observed, that had been recently cut by the natives in search of honey or opossums. Emus were very numerous; sometimes a solitary bird, and at others two, three, four, and up to thirteen together, were seen trotting off in long file, and now and then stopping to stare at us. We caught a bandicoot with two young ones, which gave us an excellent luncheon. When we left the lake, Charley thought he could distinguish a plain to the northward; and, riding in that direction, I was agreeably surprised to find that the scrub did not extend more than a mile and a-half from the river; and that, beyond it, plains and open forest extended far to the northward; and fine ridges with most excellent feed, to the southward. The traveller who is merely following the course of a river, is unable to form a correct idea of the country farther off, unless hills are near, from which he may obtain extensive views. At the water-worn banks of the Mackenzie, I little expected that we were in the vicinity of a country like that of Peak Range; and I am consequently inclined to believe that much more available land exists along the banks of the Suttor, where its valley is covered with scrub, than we know anything about.

March 19.—The camp was removed to the lake of the Suttor, about twelve miles and a-half N. 80 degrees W. We chased a flock of emus, but without success; four of my companions went duck-shooting, but got very few; the others angled, but nothing would bite.

The day was cloudy; some drizzling rain fell in the morning; the night was clear. Lat. 21 degrees 37 minutes 31 minutes.

During my absence, my companions found a quantity of implements and ornaments of the natives, in the neighbourhood of our last camp.

On the plains I found two new species of Sida; and, on the tea-trees, a new form of Loranthus, with flowers in threes on a broad leafy bract, scarcely distinguishable from the real leaves.

March 20.—We travelled down to the water-holes, at which I had turned back. Sandstone rock cropped out on several spots, and pieces of broken quartz were strewed over the ground. All the water-holes along the low ridges and within the bed of the river, were full of water; and the district seemed to be one of those which, from their peculiar conformation of surface, are more frequently favoured by thunder-storms. Native companions flew down the river, and flights of ducks held their course in the same direction. With the hope of finding a good supply of water lower down, we continued our journey on the 21st March. The creek frequently divided into channels, forming large islands of a mile and a mile and a-half in length, covered with scrub, and over which freshes had swept. All at once, the water disappeared; the deepest holes were dry; the Melaleucas were not to be found; the flooded-gums became very rare, and the rich green grass was replaced by a scanty wiry grass. The whole river seemed to divide into chains of dry water-holes, scarcely connected by hollows. Two miles farther we came to a fine large water-hole, surrounded by Polygonums and young water-grass, and, at two miles farther, to another, and in about the same distance to a third. Recent camps of the natives were on each of them, and a beaten path led from one to the other. One of these holes was crossed by a weir made of sticks for catching fish. Bones of large fish, turtle shells, and heaps of muscles, were strewed round the fire places.

The whole day was bright and very hot; the wind in the afternoon from E.S.E. The latitude of our last camp was 21 degrees 31 minutes 16 seconds, being about eighteen miles W.N.W. from the lake.

Mr. Roper and Brown rode about seven miles down the river, and found that it again formed a large regular bed well supplied with water; and that the country was of a more open character. They came suddenly upon two women cooking mussels, who ran off, leaving their dinners to their unwelcome visitors, who quickly dispatched the agreeable repast; farther on they saw four men, who were too shy to approach. Charley also, whilst bringing in the horses on the morning of the 22nd, passed a numerous camp, who quietly rose and gazed at him, but did not utter a single word.

I travelled with my party to the water-holes found by Mr. Roper; on approaching them, we crossed an extensive box-flat, near that part of the river where it is split into collateral chains of holes. Talc-schiste cropped out at the latter part of the journey; its strata were perpendicular, and their direction from north-west to south-east; its character was the same as that of Moreton Bay and New England; numerous veins of quartz intersected the rock.

The water-holes were surrounded by high Polygonums; blue Nymphaeas were observed in several of them; and ducks were very numerous.

The forenoon was cloudless and hot; cirrhous clouds formed in the afternoon; with a breeze from the E.S.E. Our lat. was 21 degrees 25 minutes.

Mr. Gilbert and Charley, when on a reconnoitring ride, met another party of natives; among them two gins were so horror-struck at the unwonted sight, that they immediately fled into the scrub; the men commenced talking to them, but occasionally interrupted their speeches by spitting and uttering a noise like pooh! pooh! apparently expressive of their disgust.

March 23.—The party moved on about ten miles to the north-east, and encamped at the junction of a large creek which comes from the S.S.E. Its character is similar to that of the Suttor; and I should not be surprised if it should prove to be the northern anabranch of that creek, and which we crossed on the 17th of March, the day before we arrived at the lake.

The country opens into lightly-timbered ridges, which are composed of a hard rock, the sharp pieces of which covered the ground, and made our animals foot-sore. It seems to me to be a clayey sandstone (Psammite) penetrated by silica. A coarse-grained sandstone and quartzite cropped out in that part of the river situated between the two camps. The melon-holes of the box-flats were frequently over-grown with the polygonaceous plant, mentioned at a former occasion; and the small scrub plains were covered with a grey chenopodiaceous plant from three to four feet high. The stiff-leaved Cymbidium was still very common, and two or three plants of it were frequently observed on the same tree; its stem is eatable, but glutinous and insipid.

The morning of Easter Sunday was very clear and hot; the wind from E.N.E. As soon as we had celebrated the day with a luncheon of fat damper and sweetened tea, I rode with Charley about seven or eight miles down the river, and found abundance of water, not only in the bed of the river, but in lines of lagoons parallel to it. Charley shot several ducks, which were very numerous upon the water. Whilst riding along the bank of the river, we saw an old woman before us, walking slowly and thoughtfully through the forest, supporting her slender and apparently exhausted frame with one of those long sticks which the women use for digging roots; a child was running before her. Fearing she would be much alarmed if we came too suddenly upon her,—as neither our voices in conversation, nor the footfall of our horses, attracted her attention,—I cooeed gently; after repeating the call two or three times, she turned her head; in sudden fright she lifted her arms, and began to beat the air, as if to take wing,—then seizing the child, and shrieking most pitifully, she rapidly crossed the creek, and escaped to the opposite ridges. What could she think; but that we were some of those imaginary beings, with legends of which the wise men of her people frighten the children into obedience, and whose strange forms and stranger doings are the favourite topics of conversation amongst the natives at night when seated round their fires?

I observed a fine sienite on several spots; it is of a whitish colour, and contains hornblende and mica in almost equal quantities; granite was also seen, and both rocks probably belong to each other, the presence of hornblende being local. A very hard pudding-stone crops out about nine miles down the river. From the ridges, hills were seen to the N.N.E. and to the westward. Vitex scrub is met with in patches of small extent. A white crane, and the whistling duck, were seen. Black ducks and teal were most common, and Charley shot eight of them. On the banks of the more or less dry water-holes grows an annual leguminous plant, which shoots up into a simple stem, often to the height of twelve feet; its neck and root are covered with a spongy tissue; its leaves are pinnate, a foot or more in length, with small leaflets; it bears mottled yellow flowers, in axillary racemes; and long rough, articulate pods, containing small, bright, olive-green seeds. I first saw this plant at Limestone, near Moreton Bay, and afterwards at the water-holes of Comet River. It was extremely abundant in the bed of the Burdekin, and was last seen on the west side of the gulf of Carpentaria; I could, however, easily distinguish three species of this plant. [They belong probably to the two genera, Aeschynomene and Sesbania.]

Last evening, clouds gathered in the west, but cleared off after sunset; the night again cloudy, the forenoon equally so; in the afternoon the clouds were dissipated by a north-east wind.

March 24.—We travelled about nine miles N. 60 degrees W. along the river; a small creek joined from the westward. At night we had a heavy thunder-storm from the S.W.

March 25.—Weather very hot; clouds formed during the afternoon. We continued our journey along the river to lat. 21 degrees 3 minutes; the river winds considerably. We passed several hills at the latter part of the stage. I ascended one of them, on the right bank of the river, and obtained an extensive view of the country, which has a very uniform character. There were ridges and low ranges to the westward, one of which stretched from N. by W. far to the westward. The hill on which I stood was composed of limestone rock; it was flat-topped, with steep slopes at each end.

In lat. about 21 degrees 6 minutes, we crossed a large creek, densely lined with dropping tea trees, coming from the westward. It was here we first met with Careya arborea (Roxb.), a small tree from fifteen to twenty feet high, with elliptical leaves of soft texture, four inches long, and two in breadth; its fruit was about two inches long, contained many seeds, and resembled that of the Guava. Its leaves, however, had neither the vernation nor the pellucid dots of Myrtaceous trees. At the junction of the creek, a great number of small Corypha palms were growing, and my companions observed the dead stems of some very high ones, whose tops had been cut off by the natives, probably to obtain the young shoot. We passed hills of baked sandstone, before reaching the creek, and afterwards crossed a fine sandy flat, with poplar-gum. The river has a broad bed, at times dividing into several channels, lined with stately Melaleucas and flooded-gum, and again uniting into one deep channel, with long reaches of water surrounded by Polygonums, and overgrown with blue Nymphaeas, Damasoniums, and Utricularias, and inhabited by large flights of ducks. Rock occasionally enters into the bed of the river. The collateral lines of water-holes are rarely interrupted, and the ridges appear to be open on both sides of the river.

March 26.—We travelled along the river to lat. 20 degrees 53 minutes 42 seconds. Its course is almost due north. Yesterday, being out duck shooting, we came suddenly upon a camp of natives, who were not a little frightened by the report of our guns: they followed our tracks, however, with wailing cries, and afterwards all of them sat down on the rocky banks of the river, when we returned to our camp. To-day we passed the place of their encampment with our whole train, and it was remarkable that they neither heard nor saw us until we were close to them, though we had seen them from a great distance. All the young ones ran away. Dismounting from my horse, I walked up to an old man who had remained, and who was soon after rejoined by another man. We had a long unintelligible conversation, for neither Brown nor Charley could make out a single word of their language. They were much surprised by the different appearance of Charley's black skin and my own. Phillips wished to exchange his jacket for one of their opossum cloaks, so I desired him to put it on the ground, and then taking the cloak and placing it near the jacket, I pointed to Phillips, and, taking both articles up, handed the cloak to Phillips and the jacket to our old friend, who perfectly understood my meaning. After some time he expressed a wish to have the cloak back, and to keep the jacket, with which we had dressed him; but I gave him to understand that he might have his cloak, provided he returned the jacket; which arrangement satisfied him. A basket (dilli), which I examined, was made of a species of grass which, according to Charley, is found only on the sea coast.

We saw a Tabiroo (Mycteria) and a rifle bird. The morning was cloudy, but very hot. Numerous heavy cumuli formed during the afternoon.

March 27.—We travelled to lat. 20 degrees 47 minutes 34 seconds. The country along the river is undulating and hilly, and openly timbered. The rock is of sandstone, and the ground is covered with quartz pebbles. In lat. about 20 degrees 49 minutes, the Suttor is joined by a river as large as itself, coming from the S.W. by W., and which changes the course of the Suttor to the N.E. Just before the junction, the large bed of the Suttor contracts into one deep channel, filled in its whole extent by a fine sheet of water, on which Charley shot a pelican. I mention this singular contraction, because a similar peculiarity was observed to occur at almost every junction of considerable channels, as that of the Suttor and Burdekin, and of the Lynd and the Mitchell. I named the river, which here joins the Suttor, after Mr. Cape, the obliging commander of the Shamrock steamer. The bed of the united rivers is very broad, with several channels separated by high sandy bergues. The country back from the river is formed by flats alternating with undulations, and is lightly timbered with silver-leaved Ironbark, rusty gum, Moreton Bay ash, and water box. The trees are generally stunted, and unfit for building; but the drooping tea trees and the flooded-gum will supply sufficient timber for such a purpose.

At our camp, at the bed of the river, granite crops out, and the sands sparkle with leaflets of gold-coloured mica. The morning was clear and hot; the afternoon cloudy; a thunder-storm to the north-east. We have observed nothing of the sea-breeze of the Mackenzie and of Peak Range, along the Suttor; but a light breeze generally sets in about nine o'clock P.M.

Charley met with a flock of twenty emus, and hunted down one of them.

March 28.—We travelled down the river to latitude 20 degrees 41 minutes 35 seconds. The country was improving, beautifully grassed, openly timbered, flat, or ridgy, or hilly; the ridges were covered with pebbles, the hills rocky. The rocks were baked sandstone, decomposed granite, and a dark, very hard conglomerate: the latter cropped out in the bed of the river where we encamped. Pebbles of felspathic porphyry were found in the river's bed. At some old camping places of the natives, we found the seed-vessels of Pandanus, a plant which I had never seen far from the sea coast; and also the empty shells of the seeds of a Cycas. Mr. Calvert, John Murphy, and Brown, whom I had sent to collect marjoram, told me, at their return, that they had seen whole groves of Pandanus trees; and brought home the seed-vessel of a new Proteaceous tree. I went to examine the locality, and found, on a sandy and rather rotten soil, the Pandanus abundant, growing from sixteen to twenty feet high, either with a simple stem and crown, or with a few branches at the top. The Proteaceous tree was small, from twelve to fifteen feet high, of stunted and irregular habit, with dark, fissured bark, and large medullary rays in its red wood: its leaves were of a silvery colour, about two inches and a half long, and three-quarters broad; its seed-vessels woody and orbicular, like the single seed-vessels of the Banksia conchifera; the seeds were surrounded by a broad transparent membrane. This tree, which I afterwards found every where in the neighbourhood of the gulf of Carpentaria, was in blossom from the middle of May to that of June. The poplar-gum, the bloodwood, the melaleuca of Mt. Stewart, the Moreton Bay ash, the little Severn tree, and a second species of the same genus with smooth leaves, were growing on the same soil. The grasses were very various, particularly in the hollows: and the fine bearded grass of the Isaacs grew from nine to twelve feet in height. Charley brought me a branch of a Cassia with a thyrse of showy yellow blossoms, which he said he had plucked from a shrub about fifteen feet high.

We encamped about two miles from the foot of a mountain bearing about N.E. from us; I called it Mount McConnel, after Fred. McConnel, Esq., who had most kindly contributed to my expedition. The Suttor winds round its western base, and, at four or five miles beyond it, in a northerly direction, and in latitude 20 degrees 37 minutes 13 seconds joins a river, the bed of which, at the junction, is fully a mile broad. Narrow and uninterrupted belts of small trees were growing within the bed of the latter, and separated broad masses of sand, through which a stream ten yards broad and from two to three feet deep, was meandering; but which at times swells into large sheets of water, occasionally occupying the whole width of the river. Charley reported that he had seen some black swans, and large flights of ducks and pelicans. This was the most northern point at which the black swan was observed on our expedition.



CHAPTER VII



THE BURDEKIN—TRANSITION FROM THE DEPOSITORY TO THE PRIMITIVE ROCKS—THACKER'S RANGE—WILD FIGS—GEOLOGICAL REMARKS—THE CLARKE—THE PERRY.

As this place afforded every convenience for killing and curing another bullock, we remained here for that purpose from the 29th March to the 2nd of April. The weather was favourable for our operations, and I took two sets of lunar observations, the first of which gave me longitude 146 degrees 1 minutes, and the second, 145 degrees 58 minutes. The mornings were generally either cloudless, or with small cumuli, which increased as the day advanced, but disappeared at sunset; the wind was, as far as I could judge, northerly, north-easterly, and easterly.

April 2.—The Suttor was reported by Charley to be joined by so many gullies and small creeks, running into it from the high lands, which would render travelling along its banks extremely difficult, that I passed to the east side of Mount McConnel, and reached by that route the junction of the Suttor with the newly discovered river, which I called the Burdekin, in acknowledgment of the liberal assistance which I received from Mrs. Burdekin of Sidney, in the outfit of my expedition. The course of this river is to the east by south; and I thought that it would most probably enter the sea in the neighbourhood of Cape Upstart. Flood marks, from fifteen to eighteen feet above the banks, showed that an immense body of water occasionally sweeps down its wide channel.

I did not ascend Mount McConnel, but it seemed to be composed of a species of domite. On the subordinate hills I observed sienite. The bed of the river furnished quite a collection of primitive rocks: there were pebbles of quartz, white, red, and grey; of granite; of sienite; of felspathic porphyry, hornblende, and quartz-porphyry; and of slate-rock.

The morning was cloudless. In the afternoon, heavy cumuli, which dissolved towards sunset; a strong wind from the north and north by east.

A very conspicuous hill, bearing E.N.E. from the junction of the rivers, received the name of Mount Graham, after R. Graham, Esq., who had most liberally contributed to my expedition.

Mr. Gilbert found a large calabash attached to its dry vine, which had been carried down by the waters. Several other very interesting cucurbitaceous fruits, and large reeds, were observed among the rubbish which had accumulated round the trees during the flood.

April 3.—We travelled up the Burdekin, in a north-north-west direction, to latitude 20 degrees 31 minutes 20 seconds. The country was hilly and mountainous; the soil was stony; and the banks of the river were intersected by deep gullies and creeks. The forest vegetation was the same as that on the lower Suttor. Among the patches of brush which are particularly found at the junction of the larger creeks with the river, we observed a large fig-tree, from fifty to sixty feet high, with a rich shady foliage; and covered with bunches of fruit. The figs were of the size of a small apple, of an agreeable flavour when ripe, but were full of small flies and ants. These trees were numerous, and their situation was readily detected by the paths of the natives leading to them: a proof that the fruit forms one of their favourite articles of food. The drooping tea trees, which had increased both in number and size, grew in company with an arborescent Calistemon, along the water's edge; and a species of Eucalyptus, somewhat resembling Angophora intermedia, was discovered at this spot: it occurs frequently to the northward, and is common round the gulf of Carpentaria. The small Acacia tree of Expedition Range was frequently seen in the forest, and was covered with an amber-coloured gum, that was eatable, but tasteless: Hakea lorea (R. Br.), and Grevillea ceratophylla (R. Br.); the Ebenaceous tree, and that with guava-like fruit (lareya), were all numerous. The bed of the river was covered with the leguminous annual I noticed at the Suttor; it grew here so high and thick that my companions were unable to see me, though riding only a few yards from them.

Rock frequently crops out in the bed of the river, and in the neighbouring hills. Several hills at the right bank were formed by a kind of thermantide of a whitish grey, or red colour, and which might be scratched easily with a penknife. Other conical hills or short ranges, with irregular rugged crests, were composed of granite of many varieties, red and white, fine grained without hornblende, or containing the latter substance, and changing into sienite; and, at one place, it seemed as if it had broken through Psammite. I observed quartzite in several localities, and a hard pudding-stone extending for a considerable distance. We were, no doubt, on the transition from the depository to the primitive rocks; and a detailed examination of this interesting part of the country would be very instructive to the geologist, as to the relative age and position of the rocks.

A small fish, with yellow and dark longitudinal lines, and probably belonging to the Cyprinidae, was caught. Wind prevailed from the northward: the forenoon was cloudless; heavy cumuli in the afternoon.

We travelled at first on the right side of the river; but its banks became so mountainous and steep, and the gullies so deep, that we were compelled to cross it at a place where it was very deep, and where our horses and cattle had to swim. Many of our things got wet, and we were delayed by stopping to dry them.

April 4.—We moved our camp to latitude 20 degrees 24 minutes 12 seconds, a distance of about nine miles N.W. by N. We passed several granitic peaks and ranges; one of which I ascended, and enjoyed an extensive view. The character of the country changed very little: open narrow-leaved Ironbark forest on a granitic sand, full of brilliant leaflets of mica. Some deep creeks came from the eastward. To the west and north-west nothing was to be seen but ridges; but high imposing ranges rise to the north and north-east. At one spot, large masses of calcareous spar were scattered over the ground; they were probably derived from a vein in the granite.

Three black ducks, (Anas Novae Hollandiae) were shot. Tracks of native dogs were numerous; and a bitch came fearlessly down to the river, at a short distance from our camp. Our kangaroo dog ran at her, and both fell into the water, which enabled the bitch to escape.

April 5.—We re-crossed the river, which was not very deep, and travelled about nine miles N. 75 degrees W. The river flows parallel to a high mountain range, at about three or four miles from its left bank. I named this after Mr. Robey, another friendly contributor to my outfit. A large creek very probably carries the waters from this range to the Burdekin, in latitude 20 degrees 23 minutes. The country was very ridgy and hilly; and we found it exceedingly difficult to proceed along the river. We observed the poplar-gum again in the open forest, and a fine drooping loranthus growing on it. Pandanus was also very frequent, in clusters from three to eight trees. The clustered fig-tree gave us an ample supply of fruit, which, however, was not perfectly mellow.

Veins of calcareous spar and of quartz were again observed. I ascended a lofty hill, situated about a mile and a half to the west of our encampment, and found it composed of felspathic porphyry, with a greyish paste containing small crystals of felspar; but, in the bed of the river, the same rock was of a greenish colour, and contained a great number of pebbles of various rocks, giving it the aspect of a conglomerate; but recognisable by its crystals of felspar, and from its being connected with the rock of the hill. From the top of the hill, which is wooded with a silver-leaved Ironbark, I saw a very mountainous country to the N.N.W. and northward, formed into detached ranges and isolated peaks, some of which were apparently very high; but to the north-west and west no ranges were visible.

A thunder-storm threatened on the 4th, but we had only some light showers: the morning of the 5th was very hot, and the afternoon rainy. Wind from north and north-east. Nights clear.

April 6.—We travelled about ten miles N. 35 degrees W. over a ridgy, openly timbered, stony and sandy country, and crossed several sandy creeks, in which a species of Melaleuca, and another of Tristania were growing. No part of the country that we had yet seen, resembled the northern parts of New England so much as this. The rock was almost exclusively granitic isolated blocks; detached heaps, and low ridges composed of it were frequently met with in the open forest. We passed two small hillocks of milkwhite quartz; fragments of this rock, as well as of calcareous spar, were often observed scattered over the ground. The river here made a large bend to the northward, still keeping parallel to Robey's Range, or a spur of it; and, when it again turned to the westward, another fine high range was visible to the north by east and north-east of it; which I named "Porter's Range," in acknowledgment of the kindness of another of the contributors to my expedition. Its latitude is about 20 degrees 14 minutes.

April 7.—Travelled about ten miles N. 70 degrees W. The country became more level, more open, and better grassed; the gullies were farther apart, and headed generally in fine hollows. Two large creeks joined the river from the westward; and a still larger one came from the northward, and which probably carries off the water from the country round a fine peak, and a long razorback mountain which we saw in that direction. North-west of Porter's Range, and between it and the razorback, were two small peaks. The timber is of the same kind, but larger. The poplar-gum was more frequent, and we always found patches of fine grass near it; even when all the surrounding Ironbark bark forest was burnt. The large clustered fig-trees were not numerous along the river; we perhaps passed from three to five in the course of a day's journey; though young ones, without fruit, were often seen.

Heavy clouds gathered during the afternoon of the 6th, and it rained throughout the night; the wind was from N. and N.E. In the morning of the 7th some drops of rain fell, but the weather cleared up during the day; wind easterly. The moon changed this day, and we experienced a heavy thunder-storm during the afternoon.

April 8.—We travelled about nine miles N. 70 degrees W., to latitude 20 degrees 9 minutes 11 seconds. The river made a bend to the southward, and then, at a sharp angle, turned again to the north-west. At this angle a large creek joined it from the south; another instance of creeks joining larger channels, coming in a direction almost opposite to their course. Two other creeks joined the Burdekin during this stage; one from the south-west, and another from the north. The grass was particularly rich at these junctions. The river became considerably narrower, but still had a fine stream. Thunder-storms had probably fallen higher up its course, causing a fresh; for its waters, hitherto clear, had become turbid. Narrow patches of brush were occasionally met with along its banks, and I noticed several brush trees, common in other parts of the country. Besides the clustered fig, and another species with rough leaves and small downy purple fruit, there were a species of Celtis; the Melia Azederach (White Cedar); a species of Phyllanthus, (a shrub from six to ten feet high); an Asclepiadaceous climber, with long terete twin capsules; and several Cucurbitaceae, one with oblong fruit about an inch long, another with a round fruit half an inch in diameter, red and white, resembling a gooseberry; a third was of an oblong form, two inches and a half long and one broad; and a fourth was of the size and form of an orange, and of a beautiful scarlet colour: the two last had an excessively bitter taste. The night and morning were cloudy, with a southerly wind, but it cleared up at eleven o'clock. Cumuli in the afternoon, with wind from the south-east.

From our camp we saw a range of hills, bearing between N. 5 degrees W. and N. 10 degrees W.; they were about three miles distant. I called them "Thacker's Range," in acknowledgment of the support I received from—Thacker, Esq., of Sidney.

April 9.—We travelled about nine miles W. by N., and made our latitude 20 degrees 8 minutes 26 seconds. The western end of Thacker's Range bore N.E. Two large creeks joined the river from the south and south-west. The country was openly timbered; the Moreton Bay ash grew along the bergue of the river, where a species of Grewia seemed its inseparable companion. The flooded-gum occupied the hollows and slopes of the river banks, which were covered with a high stiff grass to the water's edge, and the stream was fringed with a thicket of drooping tea trees, which were comparatively small, and much bent by the force of floods, the probable frequency of which may account for the reduced size of the tree. The ridges were covered with rusty Gum and narrow-leaved Ironbark. An Erythrina and the Acacia of Expedition Range were plentiful. The grass was rich and of various species. The granite rock still prevailed. A felspathic rock cropped out near the second creek, where I met with a dark rock, composed of felspar and horneblende (Diorite.) Our camp was pitched at the foot of a series of small conical hills, composed of porphyry. A larger range to the southward of it was also porphyritic, very hard, as if penetrated by quartz, and containing small crystals of flesh-coloured felspar. Sienite cropped out on the flats between these two ranges. I commanded a most extensive view from the higher range. High and singularly crenelated ranges were seen to the south-west; detached peaks and hills to the westward; short ranges and peaks to the north; and considerable ranges between north and north-east. A river was observed to join the Burdekin from the ranges to the south-west.

Numerous kangaroos were seen bounding over the rocky slopes to the grassy glens below. A stunted silver-leaved Ironbark covered the hills.

April 10.—The night was very cold, particularly towards morning, and the dew heavy; the morning was calm; a breeze from the south-east set in at nine o'clock a.m.; cumuli formed about eleven o'clock, and became very heavy during the afternoon.

The country over which we travelled about eight miles N. by W., was one of the finest we had seen. It was very open, with some plains, slightly undulating or rising into ridges, beautifully grassed and with sound ground. We crossed the river I had seen the preceding day from the hill, and found it running. Two large creeks, one from the right and the other from the left, also joined the Burdekin. I observed Pegmatite of a white colour, and hornblende Porphyry and Diorite. A shrubby Clerodendron and an arborescent Bursaria, covered with white blossoms, adorned the forest. The latitude was 20 degrees 0 minutes 36 seconds.

April 11.—We continued our journey up the river, in a W.N.W. direction, for about ten miles. The first part of our journey lay through a most beautiful country. The hollows along the river were covered with a dense sward of various grasses, and the forest was open as far as the eye could reach. Farther on, however, we occasionally met with patches of Vitex scrub, and crossed some stony ridges. A small river joined from the north-east, at about a mile and a half from the last camp, and also two large creeks from the south-west. I ascended the hills opposite our camp, and looked over an immense and apparently flat country, out of which small peaks and short ranges rose. The hills on which I stood were composed of Pegmatite, with patches of white Mica in large leaflets. During the journey we found granite changing into gneiss, diorite, and quartz rock.

On the rocky crest of the hill, I gathered the pretty red and black seeds of a leguminous climbing shrub (Abrus precatorius). Phonolithic or basaltic pebbles made me suppose that we were near to a change of country. Our latitude was 19 degrees 58 minutes 11 seconds.

April 12.—We had scarcely travelled a mile and a half, when we had to cross a large creek, which increased in size higher up. Box-tree flats and open Vitex scrub extended along its banks, and the latter, according to Mr. Roper's account, changed into dense Bricklow scrub. At the junction of the creek and the river, we came on a dyke of basalt, the flat summit of which was so rough that we were compelled to travel along the flats of the creek, which for a long distance ran parallel to the Burdekin. The soil on the basalt was so shallow that it sustained only a scanty vegetation of grass and some few scattered narrow-leaved Ironbark trees. We crossed this dyke, however, and at about three miles descended from it into a fine narrow-leaved Ironbark flat, extending along the river, in which another large creek from the south-west joined the Burdekin. The flat was bounded by hills of limestone, cropping out in large blocks, with visible stratification, but without fossils. Having passed the third creek in the course of this day's journey, we encamped on the commencement of another basaltic dyke. The bed of the creek was full of blocks of Sienite, of hornblende Porphyry, of greenish Pegmatite, and of cellular Basalt. The river here formed a large sheet of water; large masses of a white Sienite protruded out of it, opposite the junction of the creek. The opposite bank exhibited a very perfect and instructive geological section of variously bent and lifted strata of limestone, which was afterwards found to contain innumerable fossils, particularly corals and a few bivalve shells. The Rev. W. B. Clarke, of Paramatta, kindly undertook to examine the fossils brought from this locality. One he determined to be an undescribed species of Cyathophyllum, and has done me the honour to give my name to it [Refer Note 1 at end of chapter]. The others belonged principally to the following genera, viz., Asterias, Caryophyllea, and Madrepora. The right bank of the river rose into steep cliffs of basalt, under which the clustered fig tree, with its dense foliage, formed a fine shady bower. The basaltic dyke was about a mile and a half broad, and I followed it about five miles up the river. Its summit was flat, rough, and rocky; at the distance of four miles from our camp it receded a little from the river, and there limestone was observed, crowded with fossils like that on the opposite side of the river. Two miles farther, the bed of the river was formed by a felspathic rock, with beautiful dendrites. A small island, with a chain of lagoons on one side, and with the river on the other, was also composed of this rock, in contact with, and covered by, basalt in several places. There were small falls and rapids in several parts of the river. A beaten foot-path of the natives, and many fire-places, showed that this part of it was much frequented by them. Wallabies were very numerous between the cliffs of the felspathic rock; and the fine fig trees along the banks of the river were covered with ripe fruit. The river made a wide sweep round the left side of a large limestone hill, whilst a chain of deep basaltic water-holes continued on its right. The basalt ceased to the westward of the limestone hill, and was succeeded by considerable flats of Ironbark, Moreton Bay ash, and Bloodwood. The Capparis still exhibited a few showy flowers. I examined the country thus far on the 12th April, after the camp had been formed; on returning, I took with me a large supply of ripe figs, of which we partook freely, and which caused several of us to suffer severely from indigestion, though we had frequently eaten small quantities of them without inconvenience.

April 13.—We avoided the field of basalt by moving up the creek we last crossed, about four miles, and by crossing over to the flats of the river where the basalt terminated. These flats, however, were again interrupted by a basaltic dyke, over which we were compelled to travel, as the steep banks of the river were on one side, and black bare rocks, forming sometimes regular walls with a dense scrub between them, prevented us from turning to the other. After descending from the basalt, we crossed a good-sized creek from the south-west, and travelled over a fine open country to lat. 19 degrees 49 minutes 41 seconds.

Two hills were close to the left side of the Burdekin, which, at their base, were joined by a large running creek from the N.N.W. From the limestone hill of yesterday, no other hill was visible to the westward, though ranges and isolated hills lay to the north and north-east, and a high blue mountain to the south-west.

Some days ago I found, for the first time, Spathodea alternifolia (R. Br.), which we continued to meet with throughout the remainder of our journey. I saw but one flower of it, but its falcate seed-vessels, often more than a foot long, were very numerous. Pandanus spiralis was frequent. The box (Eucalyptus), on the flats along the creek, the soil of which is probably formed of the detritus of basaltic rock, had a lanceolate glossy leaf, uniting the character of the box with glossy orbicular leaves growing generally on the whinstone soil of the northern parts of the colony, and of the box with long lanceolate leaves which prefers stiff flats on the tributary creeks of the Hunter. A Bottle-tree with a Platanus leaf (Sterculia?) grew in the scrub on the field of basalt, and was in full blossom. A pretty species of Commelyna, on the flats, a cucurbitaceous plant with quinquepalmate leaves and large white blossoms, grew along the river, the approaches of which were rendered almost inaccessible by a stiff high grass. Charley brought me the long flower-stalk of Xanthorrhaea from some ridges, which were, doubtless, composed of sandstone.

Two kangaroos were seen; they were of middle size, and of a yellowish grey colour, and seemed to live principally about the basaltic ridges.

The cooee of natives had been heard only once during our journey along the banks of the Burdekin; and the traces of their former presence had not been very frequently observed. Large lagoons full of fish or mussels form a greater attraction to the natives than a stream too shallow for large fish, and, from its shifting sands, incapable of forming large permanent holes. Wherever we met with scrub with a good supply of water, we were sure of finding numerous tracks of the natives, as game is so much more abundant where a dense vegetation affords shelter from its enemies.

April 14.—Last night, at seven o'clock, a strong breeze set in from the northward, and continued for about an hour, when it became perfectly calm. If this was the same breeze which we had observed at the Mackenzie at eight o'clock, and which set in earlier and earlier, as we travelled along the Isaacs and Suttor (though it was less regular in these places) until we felt it at about six o'clock, we were now most evidently receding from the eastern coast.

We travelled in a N. 60 degrees W. direction to lat. 19 degrees 45 minutes 36 seconds. A basaltic ridge, similar to those we had passed, extended in an almost straight line from south-east to north-west; it was covered with a scanty vegetation, with a few small narrow-leaved Ironbark trees and Erythrinas; the river now approached it, now left it in wide sweeps enclosing fine narrow-leaved Ironbark flats. To the south-west side of this ridge or dyke, the soil is basaltic, with box-trees and open Vitex scrub. The sharp conical hills of the white ant, constructed of red clay, were very numerous. A very perfect bower of the bower-bird was seen in a patch of scrub trees.

In a gully, a loose violet coloured sandstone cropped out, over which the basalt had most evidently spread. Farther on, the ridge enlarged and formed small hillocks, with bare rock cropping out at their tops;—a form of surface peculiar to the basaltic or whinstone country of this colony.

Charley shot the sheldrake of Port Essington, (Tadorna Rajah). The singular hissing or grinding note of the bower bird was heard all along the river; the fruit of the fig trees growing near, which seemed to supply it with its principal food during this part of the year.

April 15.—One of our bullocks had gone back on our tracks, and thereby prevented our starting so early as usual. We travelled in a N. 40 degrees W. direction to latitude 19 degrees 41 minutes 25 seconds. The basaltic country continued, and apparently extended a great distance from the river. The flats along the latter were less extensive. Sandstone cropped out in deep gullies, and in the bed of the river; it was naturally soft and coarse, but where it rose into hillocks near basalt, it changed into a fine baked sandstone, resembling quartzite, which, when in contact with the igneous rock, looked like burnt bricks. Near our camp, a dyke or wall of the aspect of a flinty red conglomerate, crossed the river from south-west to north-east. I believe that this rock belongs to the porphyries of Glendon, and of the upper Gloucester. We continued to feel the breeze, or rather a puff of wind, between 7 and 8 o'clock at night; it was often very strong and cold, and prevented the mosquitoes from molesting us.

April 16.—We proceeded north by west to latitude 19 degrees 32 minutes, and crossed several gullies coming from the basaltic ridges: these, however, receded far from the river, and large box and Ironbark flats took their place for about three miles, when the ridges re-appeared. Between four and five miles from the bar of red rock above mentioned, a fine large creek joined the Burdekin from the westward. The box and Ironbark forest was interrupted by slight rises of limestone full of corals; and by a higher hill of baked sandstone, at the foot of which a limestone hill was covered with a patch of Vitex scrub. The strata of the limestone seemed to dip to the southward.

The opposite banks of the river were ridgy, but openly timbered, and this fine country, with its well grassed flats, and its open ridges, seemed to extend very far on both sides. Messrs. Gilbert and Roper went to the top of the hill, and saw ranges trending from west to north, with that crenelated outline which I had before seen and mentioned: they distinguished a large valley, and the smoke of several fires of the natives along the range. A large lagoon was at the western foot of the hill on which they were. A large creek was seen, by Brown, to join the Burdekin from the north-east, at a short mile from our encampment. A baked sandstone and pudding-stone of a white colour projected into the river at the place, which not only exhibited the transition from one rock into the other, but it showed the action of igneous rocks on both, and gave a clue to the nature of the red rock I described yesterday. In the thicket which covered the rock, I observed Pomaderris of Moreton Bay. In decreasing our latitude, both Mr. Gilbert and myself were inclined to think that, whenever a bird or a plant disappeared, it was owing to that circumstance. In this, however, we were frequently mistaken: trees and herbaceous plants disappeared with the change of soil, and the decrease of moisture, and the birds kept to a certain vegetation: and, as soon as we came to similar localities, familiar forms of plants and birds re-appeared. Almost all the scrub-trees of the Condamine and Kent's Lagoon were still to be seen at the Burdekin; and the isolated waters near grassy flats were visited by swarms of little finches, which Mr. Gilbert had observed at Port Essington, and which, in all probability, belonged to the whole extent of country between that place and the region of the tropics. This slight change of vegetation, and particularly of the inland Flora, from south to north, is no doubt connected with the uniformity of the soil and climate: and the immense difference which exists between the eastern and western coast, has led men of science and of observation, not without good reason, to infer that this continent was originally divided into two large islands, or into an archipelago, which have been united by their progressive, and, perhaps, still continued, elevation. As an exception, however, to this remark, a very sudden change of the Flora was observed, when we entered into the basin of the gulf of Carpentaria, after leaving the eastern waters, although the Flora of the north-west coast and Port Essington, was little different from that of the gulf.

April 17.—We travelled about nine miles N. 40 degrees W. On our way we passed a hill of baked sandstone, and several gullies. About five miles from our last camp, a large creek joined the river; beyond that creek, the country was, without exception, open, and rather of a more undulating character; the flats were somewhat rotten: the river became narrower, but was still running strong; and numerous ducks sported on its shady pools.

April 18.—Last night we had a very cold north-easterly wind, and, during the day, some few drops of drizzling rain. We travelled about N. by W. to latitude 19 degrees 18 minutes 16 seconds. After passing some gullies, we came into a more broken and hilly country; the river formed here a large anabranch. The Ironbark trees, which timbered the extensive flat along the river, became much finer; but the soil was rotten: the poplar-gum grew on the stiff soil of the hollows. About six miles from our last camp, we came to ranges of high hills of a conical form, and with rounded tops, striking from west to east, and then entered a narrow valley, bounded on each side by rocky hills. Mr. Roper observed a rugged country to the northward, and a fine high range to the south-east. The whole country from the large flat to our camp, was composed of felspathic porphyry, containing crystals of felspar, and accidentally of quartz, in a paste varying in colour and hardness. In the bed of the river, I still found pebbles of pegmatite, granite, quartz, and basalt; indicating that a country of varied character was before us.

The stream wound its way from one side of the broad sandy bed to the other; and those parts where it flowed, were generally very steep, and covered with a dense vegetation, whilst, on the opposite side, the banks sloped gently into the broad sands. Among the shrubs and grasses, a downy Abutelon was easily distinguished by its large bright yellow blossoms.

My Blackfellows procured several messes of ducks; and Brown brought me a piece of indurated clay with impressions of water-plants.

April 19.—Continuing our journey in a north-west direction, we passed over some very rocky hills, composed of indurated clay, and thin strata of sandstone, and pudding-stone. By moving along the foot of a range of high hills, we avoided all those deep gullies which intersected the banks of the river, and travelled with ease through a flat, well grassed Ironbark forest. The hills were covered, as usual, with stunted silver-leaved Ironbark. A large creek came from the range, and entered the river. A good section on its right bank exposed to view the strata of indurated clay and sandstone; and I was induced to believe that coal might be found below them. As we were passing over the flat between the creck and the river, we saw a native busily occupied in burning the grass, and eagerly watching its progress: the operation attracted several crows, ready to seize the insects and lizards which might be driven from their hiding places by the fire. Mr. Calvert, Brown, and Charley, rode nearly up to the man before he was aware of their approach; when he took to his heels, and fled in the greatest consternation.

Upon reaching the river, at about eight miles from our last camp, we found that it was joined by another river of almost the same size as the Burdekin: it had a stream, and came from the northward, whilst the course of the Burdekin at this place was from the west to east. From the junction a long range trended to the north-east, and moderate ranges bounded the valley of the river from the northward; another range extended along the left side of the Burdekin above the junction; and basaltic ridges, which had broken through the sandstone, approached on its right. The cucurbitaceous plant with palmate leaves, bore a fruit of the size of a large orange, of a fine scarlet colour when ripe; its rind is exceedingly bitter, but the seeds are eaten by birds. Mr. Phillips found a flesh-coloured drupaceous oblong fruit, about half an inch long, with a very glutinous pericarp, containing a slightly compressed rough stone: in taste it resembled the fruit of Loranthus, and the birds, particularly the coekatoos, appeared very fond of it. We all ate a great quantity of them, without the slightest injury. It grew on a small tree, and had a persistent calyx.

April 20.—We travelled in a N. 80 degrees W. course to latitude 19 degrees 9 minutes 88 seconds. Rocky ranges frequently approached the river, and deep and intricate gullies descended from them to the latter. Our progress was consequently very difficult, and we were compelled to ascend a very high hill to avoid its slopes towards the river, which were too steep for us to cross. As a recompense, however, for the difficulty of the ascent, I had the pleasure of finding some very interesting plants on its summit; particularly a small Acacia with verticillate leaves, which Dr. Binoe, the surgeon of H. M. S. Beagle, had found on the north-west coast; and two other Acacias equally new to me, and which were afterwards found to extend to the heads of the South Alligator River. From this hill we had a magnificent view of the country before us: it was enclosed on all sides by high mountain ranges, of which one in particular overtopped the rest. Porphyry was observed on several spots; indurated clay frequently; and, on the top of the hill below which we encamped, I found quartz porphyry, and at the foot a psammite? which I had met several times associated with talc-schiste.

April 21.—We continued our journey in a S. 50 degrees W. course to latitude 19 degrees 13 minutes. The country became still more mountainous; we passed, notwithstanding, many large well grassed flats, on which the timber grew to a greater size than we had observed it at the lower part of the river. The poplar-gum was very frequent in the hollow, and low stiff flats extended parallel to the river. The prevailing rock was talc-schiste, alternating with layers of psammite. On the hills and in the creeks, I frequently observed conglomerate, with many pieces of quartz.

The drooping Hakea of Kent's Lagoon (Hakea lorea, R. Br.; Grevillea lorea, R. Br. Prodr. Nov. Holl. I. p. 380) was in blossom; and on the rocky slopes I found a new species of Hakea, having linear lanceolate leaves with axillary fascicules of small brownish flowers: it was an arborescent shrub, from three to six feet high; and is nearly allied to H. arborescens (R. Br. Prodr. p. 386).

A high imposing range was visible to the northward.

April 22.—We travelled about nine miles west, making our latitude 19 degrees 12 minutes. Ranges ran parallel to the river at different distances: we left a very fine one to the south-west and south, from which the large creek we passed about two miles from our last camp, probably descends. Three miles farther, a river as large or even larger than the Burdekin, joins the latter from the westward and south-west— the Burdekin coming down from the north-west. I was doubtful which of the two rivers I ought to follow; but finding, after a close examination, that the north-west branch was running, whilst the south-west one contained only large, long, but unconnected reaches of water, I determined upon following the north-west branch. I called the south-west branch the "Clarke," in compliment to the Rev. W. B. Clarke of Paramatta, who has been, and is still, most arduously labouring to elucidate the meteorology and the geology of this part of the world. About three miles above the junction, a creek of considerable size joined the Burdekin from the northward. Wherever the ridges approached the banks of the river, gullies which were scrubby at their heads, became numerous. After having encamped, I rode over to the "Clarke," to examine the intervening country. The flat along the Burdekin was about two miles and a half broad, and was skirted by silver-leaved Ironbark ridges. In approaching the Clarke, we came to a low basaltic range, which bounded its fine broad openly timbered valley to the northward. The bed of the river was formed by talc-schiste, in strata, the strike of which was from north by west to south by east, standing almost perpendicular, with a slight dip to the eastward. The stream was perpendicular on the line of striking. The pebbles in its bed were mostly basaltic, baked sandstone, conglomerate, quartz, sienite, and porphyry. I had observed the valley of this river from a high hill near our last camp, and had distinguished many headlands, which I now think were the bluff terminations of lateral basaltic ranges. The valley was bounded on its southern side by a long low range.

The blue mountain parrot was very frequent near our camp.

I have mentioned a small round eatable tuber, which I found in the basket of a native gin on the 2nd January. I here found it to be the large end of the tap root of a Potamogeton, or a plant nearly allied to that genus; I found it with another interesting water-plant, with foliated spikes of blue flowers, in a small water-hole near our last camp.

April 23.—We travelled about north-west to latitude 19 degrees 4 minutes 41 seconds, over a succession of fine flats; one or two of which were almost exclusively timbered with poplar-gum, which always indicated a sound stiff soil. These flats were separated by shallow gullies, and some Casuarina creeks, which come probably from the dividing ridges of the two rivers. Ridges and ranges were seen on both sides, at different distances. The Casuarina became more frequent along the banks of the river. It was rather remarkable that the Moreton Bay ash, which is so abundant along the Burdekin, was altogether wanting at the Clarke. Several lagoons were observed at the foot of the ridges; and near them we saw two flocks of the harlequin pigeon (Peristera histrionica). Talc-schiste cropped out in one of the deep creeks. Whilst travelling on the Burdekin, with the exception of some ducks and a few kangaroos, we had seen but very little game; but yesterday, when riding to the Clarke, two flocks of kangaroos passed me: a proof that the country is not so destitute of game as I had thought. The waters are inhabited by four varieties of fish; one was probably a Gristes, about eight inches long, and from one and a half to two inches broad, of a lanceolate shape, with bright yellow spots all over the body; a second smaller than Gristes, with dark stripes; a third about a foot long, and three inches broad, belonging to the Percidae; and a fourth, a small fish, which seemed to be allied to the Cyprinidae. Larger fish exist, probably, in the deep rocky basins of water which we occasionally passed; but we never succeeded in catching any; nor did we hear any of the splashing, which was so incessant during the night at the Mackenzie. The shell and bones of the turtle indicated its presence in the shady ponds fringed by drooping tea trees. Large holes in the banks immediately above the water, were probably inhabited by water rats or lizards. A common carpet snake was killed. Whenever we passed through open Vitex scrub, with its stiff loamy soil, we were sure of meeting a great number of the conical constructions of the white ant: they were from one to three feet high, very narrow, and tapering to a sharp point.

April 24.—To-day we travelled along the river over an open country, intersected by some gullies; the course of the river was, for about four miles, from north to south, and, at that distance from our camp, was joined by a river coming from the northward, which I now take the liberty of naming the "Perry," after Captain Perry, Deputy Surveyor-General, who has most kindly mapped my route from the rough plans sketched during the journey. The Burdekin here comes from the westward, and made a large bend round several mountains, composed of quartz porphyry, with a sub-crystalline felspathic paste. The latitude was 19 degrees 1 minutes (Unclear:)18.

April 25.—We travelled almost due west, about nine miles along the river, our latitude being 19 degrees 1 minutes 3 seconds. Our route lay through a fine well grassed country; the grass being very dense: at a distance from the river, I observed box flats, and poplar-gum flats; the latter are probably swampy during the rainy season. A good sized creek joined the Burdekin; a range of high hills extended along its left side, and its right became equally hilly as we approached our camping place. After establishing our camp, and making the necessary preparations, we killed one of our little steers, and found it in excellent condition. The graziers will judge by this simple fact, how well the country is adapted for pastoral pursuits; particularly when it is remembered that we were continually on the march, and had frequently to pass over very rocky ranges, which made our cattle footsore; and that the season was not the most favourable for the grass, which, although plentiful, was very dry. The steer gave us 120 lbs. of dried beef.

In this place I observed and calculated three sets of lunar observations; one gave longitude 144 degrees 4 minutes, and the other longitude 144 degrees 14 minutes. As usual, we greased our harness, although not without considerable discussion, as to whether it would not be more advisable to eat the fat than to apply it to the leather; we also repaired our packs and pack-saddles, and put every thing in travelling order.

On the 29th April we started from our killing camp, and travelled about seven miles N. 70 degrees W.; making our latitude 18 degrees 59 minutes. The ranges now approached the banks of the river, and retarded our progress very much.

April 30.—In consequence of Charley's statement, that the banks of the river in advance were so steep and rocky that it would be impossible for us to pass, I left the river side, and crossed over the ranges, and had a very heavy stage for my bullocks; which I regretted the more, as Mr. Calvert and Brown, who returned to our last camp for a sword, had found the route by the river quite practicable. The ranges were composed of a Psammite, which was frequently baked, probably by neighbouring out-bursts of igneous rock. Several familiar forms of plants were discovered; also a new Eucalyptus, with a glaucous suborbicular subcordate leaf, and the bark of the rusty gum: a stunted or middle-sized tree, which grew in great abundance on the ranges. We passed a fine large but dry Casuarina creek, coming from the westward, with a broad sandy bed. A large tree, with dark green broad lanceolate stinging leaves, grew on its banks; it resembled the nettle tree, but belonged to neither of the two species growing in the bushes of the east coast.

Our last day's travelling had not advanced us more than five miles in a straight line, and we had not made any northing, our latitude being again 18 degrees 59 minutes; but we had left the mountains behind us, and had travelled, during the latter part of the stage, over well grassed, openly timbered flats. The ranges on the left side of the river extended several miles farther, but gradually sunk into a level country.

[Note 1: The following description of the fossiliferous limestone of the Burdekin, was communicated to me by the Rev. W. B. Clarke, F.G.S.

This rock consists of a semi-crystalline, greyish-brown marble, very like some varieties of Wenlock limestone.

The most conspicuous fossil is a coral, which appears to belong to the family of Cyathophyllidae. The genus is perhaps new; but this the want of specimens with which to compare it, does not allow me the means of verifying. It may, however, be classed provisionally as Cyathophyllum, to which in many respects it bears a great resemblance; and although it is somewhat contrary to the present rules of classification to assign a specific name from a person, yet, in order to do honour to my friend on account of his skill, diligence, and zeal as a naturalist, as well as a traveller, and as this is the first fossil coral brought away by the first explorer of the region in which its habitat is found, I venture to name it C. Leichhardti.

The description may be given as follows:

Cells concavely cylindrical, not dichotomous (thus distinguished from Caryophyllia), grouped but separate, laterally if at all proliferous.

Corallum beautifully stellular, formed by 30-35 slightly spirally-curving or regular radiating lamellae, which meet in a central point or overlap on a latitudinal axial line, and are divided by rectangular or outwardly convex and upwardly oblique dissepiments, which become, occasionally, indistinct or obsolete near the centre, thus not assuming the usual characteristic of Cyathophyllum, but rather one of Strombodes.

Surface longitudinally striated, the cellular structure being hidden in calcareous spar; the striae formed by the coalescing lamellae, which, at the extremities, seem to be occasionally denticulated, owing to the matrix interrupting their passage to the edge. This resembles what takes place in some Astraeidae.

The interior has more the features of Acervularia than Cyathophyllum; but there are patches of broken transverse septa in the rock which exhibit the features of the latter.

Associated with this is a branching coral, a fragment of which, in a small angle of one of the surfaces of the stone, exhibits the characters of Favosites. There are also traces of casts of Spirifers, one of which is near to S. Pisum of the Wenlock rocks. (Silur. Syst. pl. xiii. f. 9).

The description here given is deduced from the natural appearances under the lens, and not from artificial or regular sections. But the specimen admits of a partial substitute for this; for the surface is worn down and roughly polished, as is the case with all the exposed surfaces of ancient limestones in Australia; the result probably of the acidulous properties of rain water, or of the atmosphere, which, in a tropical climate, where violent showers alternate with great drought, is capable of producing various sensible changes in rocks in a long series of ages. Many rocks of limestone in New South Wales, even harder than the Burdekin marble, are actually grooved in short parallel furrows, over wide surfaces, and along their sides, by some similar agency.]

BROWN AND CHARLEY QUARREL—NIGHT WATCH—ROUTINE OF OUR DAILY LIFE, AND HABITS OF THE MEMBERS OF THE PARTY—MOUNT LANG—STREAMS OF LAVA—A HORSE BREAKS HIS LEG, IS KILLED AND EATEN—NATIVE TRIBE—MR. ROPER'S ACCIDENT—WHITSUNDAY—BIG ANT HILL CREEK—DEPRIVED OF WATER FOR FIFTY HOURS—FRIENDLY NATIVES—SEPARATION CREEK—THE LYND—PSYCHOLOGICAL EFFECTS OF A SOJOURN IN THE WILDERNESS—NATIVE CAMP—SALT EXHAUSTED.

May 1.—We travelled west by north, to latitude 18 degrees 55 minutes 41 seconds, over almost a dead flat, which was only interrupted by a fine Casuarina creek, with a broad sandy bed, coming from the south-south-west. The soil was stiff, and the forest in which the Box tree prevailed, was very open. A species of Acacia, with narrow blunt phyllodia, about an inch long, with spinous stipules; Hakea lorea, and the Grevillea mimosoides (R. Br.), with very long linear leaves, were frequent. Towards the end of the journey, slight ridges, composed of flint rock, rose on our left; and the country became more undulating. Mr. Roper saw extensive ranges about fifteen miles distant; shortly before entering the camp, we passed a singularly broken country, in which the waters rushing down from a slightly inclined table land, had hollowed out large broad gullies in a sandy loam and iron ochre, which was full of quartz pebbles. The heavier masses had resisted the action of the waters, and remained like little peaks and islands, when the softer materials around them had been washed away. We met with grass lately burnt, and some still burning, which indicated the presence of natives. It was generally very warm during the hours of travelling, between eight and twelve o'clock, but the bracing air of the nights and mornings strengthened us for the day's labour; the weather altogether was lovely, and it was a pleasure to travel along such a fine stream of water. Easterly and north-easterly breezes still prevailed, though I expected that the direction of the winds would change as we passed the centre of York Peninsula.

Our two black companions, who until now had been like brothers—entertaining each other by the relation of their adventures, to a late hour of the night; singing, chatting, laughing, and almost crying together; making common cause against me; Brown even following Charley into his banishment—quarrelled yesterday, about a mere trifle, so violently that it will be some time before they become friends again. When Mr. Calvert and Brown returned yesterday to the camp, they remarked that they had not seen the waterfall, of which Charley had spoken whilst at our last camp; upon which Charley insinuated that they had not seen it, because they had galloped their horses past it. This accusation of galloping their horses irritated Brown, who was very fond and proud of his horse; and a serious quarrel of a rather ridiculous character ensued. Keeping myself entirely neutral, I soon found that I derived the greatest advantage from their animosity to each other, as each tried to outdo the other in readiness to serve me. To-day, Charley, who was usually the last to rise in the morning, roused even me, and brought the horses before our breakfast was ready. Brown's fondness for spinning a yarn will soon, however, induce him to put an end to this feud with his companion and countryman. In the early part of our journey, one or other of our party kept a regular night-watch, as well to guard us from any night attack of the natives, as to look after our bullocks; but, latterly, this prudential measure, or rather its regularity, has been much neglected. Mr. Roper's watch was handed from one to another in alphabetical rotation at given intervals, but no one thought of actually watching; it was, in fact, considered to be a mere matter of form. I did not check this, because there was nothing apparently to apprehend from the natives, who always evinced terror in meeting us; and all our communications with them have been accidental and never sought by them. On that point, therefore, I was not apprehensive; and, as to the bullocks, they were now accustomed to feed at large, and we seldom had any difficulty in recovering them in the morning. I shall here particularise the routine of one of our days, which will serve as an example of all the rest. I usually rise when I hear the merry laugh of the laughing-jackass (Dacelo gigantea), which, from its regularity, has not been unaptly named the settlers' clock; a loud cooee then roused my companions,—Brown to make tea, Mr. Calvert to season the stew with salt and marjoram, and myself and the others to wash, and to prepare our breakfast, which, for the party, consists of two pounds and a-half of meat, stewed over night; and to each a quart pot of tea. Mr. Calvert then gives to each his portion, and, by the time this important duty is performed, Charley generally arrives with the horses, which are then prepared for their day's duty. After breakfast, Charley goes with John Murphy to fetch the bullocks, which are generally brought in a little after seven o'clock a.m. The work of loading follows, but this requires very little time now, our stock being much reduced; and, at about a quarter to eight o'clock, we move on, and continue travelling four hours, and, if possible, select a spot for our camp. The Burdekin, which has befriended us so much by its direct course and constant stream, already for more than two degrees of latitude and two of longitude, has not always furnished us with the most convenient camps for procuring water. The banks generally formed steep slopes descending into a line of hollows parallel to the river, and thickly covered with a high stiff grass; and then another steep bank covered with a thicket of drooping tea-trees, rose at the water's edge; and, if the descent into the bed of the river was more easy, the stream frequently was at the opposite side, and we had to walk several hundred yards over a broad sheet of loose sand, which filled our mocassins, when going to wash. At present, the river is narrower, and I have chosen my camp twice on its dry sandy bed, under the shade of Casuarinas and Melaleucas, the stream being there comparatively easy of access, and not ten yards off. Many unpleasant remarks had been made by my companions at my choice of camping places; but, although I suffered as much inconvenience as they did, I bore it cheerfully, feeling thankful to Providence for the pure stream of water with which we were supplied every night. I had naturally a great antipathy against comfort-hunting and gourmandizing, particularly on an expedition like ours; on which we started with the full expectation of suffering much privation, but which an Almighty Protector had not only allowed us to escape hitherto, but had even supplied us frequently with an abundance—in proof of which we all got stronger and improved in health, although the continued riding had rather weakened our legs. This antipathy I expressed, often perhaps too harshly, which caused discontent; but, on these occasions, my patience was sorely tried. I may, however, complete the picture of the day: as soon as the camp is pitched, and the horses and bullocks unloaded, we have all our alloted duties; to make the fire falls to my share; Brown's duty is to fetch water for tea; and Mr. Calvert weighs out a pound and a-half of flour for a fat cake, which is enjoyed more than any other meal; the large teapot being empty, Mr. Calvert weighs out two and a-half pounds of dry meat to be stewed for our late dinner; and, during the afternoon, every one follows his own pursuits, such as washing and mending clothes, repairing saddles, pack-saddles, and packs; my occupation is to write my log, and lay down my route, or make an excursion in the vicinity of the camp to botanize, etc. or ride out reconnoitring. My companions also write down their remarks, and wander about gathering seeds, or looking for curious pebbles. Mr. Gilbert takes his gun to shoot birds. A loud cooee again unites us towards sunset round our table cloth; and, whilst enjoying our meals, the subject of the day's journey, the past, the present, and the future, by turns engage our attention, or furnish matter for conversation and remark, according to the respective humour of the parties. Many circumstances have conspired to make me strangely taciturn, and I am now scarcely pleased even with the chatting humour of my youngest companion, whose spirits, instead of flagging, have become more buoyant and lively than ever. I consider it, however, my invariable duty to give every information I can, whenever my companions inquire or show a desire to learn, and I am happy to find that they are desirous of making themselves familiar with the objects of nature by which they are surrounded, and of understanding their mutual relations. Mr. Roper is of a more silent disposition; Mr. Calvert likes to speak, and has a good stock of "small talk," with which he often enlivens our dinners; he is in that respect an excellent companion, being full of jokes and stories, which, though old and sometimes quaint, are always pure, and serve the more to exhilarate the party. Mr. Gilbert has travelled much, and consequently has a rich store of impressions de voyage: his conversation is generally very pleasing and instructive, in describing the character of countries he has seen, and the manners and customs of the people he has known. He is well informed in Australian Ornithology. As night approaches, we retire to our beds. The two Blackfellows and myself spread out each our own under the canopy of heaven, whilst Messrs. Roper, Calvert, Gilbert, Murphy, and Phillips, have their tents. Mr. Calvert entertains Roper with his conversation; John amuses Gilbert; Brown tunes up his corroborri songs, in which Charley, until their late quarrel, generally joined. Brown sings well, and his melodious plaintive voice lulls me to sleep, when otherwise I am not disposed. Mr. Phillips is rather singular in his habits; he erects his tent generally at a distance from the rest, under a shady tree, or in a green bower of shrubs, where he makes himself as comfortable as the place will allow, by spreading branches and grass under his couch, and covering his tent with them, to keep it shady and cool, and even planting lilies in blossom (Crinum) before his tent, to enjoy their sight during the short time of our stay. As the night advances, the Blackfellows' songs die away; the chatting tongue of Murphy ceases, after having lulled Mr. Gilbert to sleep; and at last even Mr. Calvert is silent, as Roper's short answers became few and far between. The neighing of the tethered horse, the distant tinkling of the bell, or the occasional cry of night birds, alone interrupt the silence of our camp. The fire, which was bright as long as the corroborri songster kept it stirred, gradually gets dull, and smoulders slowly under the large pot in which our meat is simmering; and the bright constellations of heaven pass unheeded over the heads of the dreaming wanderers of the wilderness, until the summons of the laughing jackass recalls them to the business of the coming day.

May 2.—We travelled in a N.W. direction to lat. 18 degrees 50 minutes 11 seconds; at first over the box flats, alternating with an undulating open country. About three miles before making our camp, we passed several small plains at the foot of what appeared to be basaltic ridges, and came to the dry channel of a river, with reeds and occasional water-holes, and lined with fine flooded-gum trees and Casuarinas, but without the dropping tea trees and the Moreton Bay ash, the latter of which seemed to be the prerogative of the Burdekin. At its left side a basaltic ridge rose, covered with thick scrub, and at its base extended a small plain, with black soil strewed with quartz pebbles. The river came, as well as I could judge, from the W.N.W. Mr. Roper and Brown caught a kangaroo, but they had a dangerous ride after it, and the poor brute, when hard pressed, showed fight, and endeavoured to lay hold of Mr. Roper.

In one of the creeks I observed pegmatite; pebbles of talc-schiste and of white quartz covered the bed of the river.

May 3.—We had to travel for a considerable distance in the bed of the river, for the hills approached close to its banks, and numerous deep gullies intercepted their slopes. When, however, the ridges receded, we passed several fine sound flats. The forest was open everywhere, and the grass was good, though old. After travelling about five miles, we saw a hill to the north-east, and, when we came almost abreast of it, the river turned to the eastward, and a wild field of broken basaltic lava rendered it impossible for us to follow its banks. The black rough masses of rock were covered with thick scrub, in which I observed numerous bottle trees with the platanus leaf. Keeping to the westward of the scrub, I followed a creek which farther on divided in a chain of ponds, into which the waters of the field of basalt, as well as of the basaltic ridges to the westward of it, collected. These ridges were perfectly level at their summits, and were connected with a table land which extended far to the west. At their foot sienite, quartz rock, and leptinite, were observed. After turning round the field of lava to the eastward, we entered into a large flat, with patches of narrow-leaved tea tree, with reedy swamps and fine flooded-gum trees, and made our camp at a strong running brook, without trees, but densely surrounded with reeds, ferns, and pothos. This stream formed the outlet of some fine lagoons, which extended along the steep slopes of the basaltic table land. I crossed the creek and its flat to the opposite hills. The flat was one level sheet or floor of basalt, here and there covered with a very shallow soil, but sometimes bare, though clothed with a fair supply of grass and with scattered flooded-gum trees. At the foot of the eastern hills, however, deep holes existed in a water-course, with black blocks of basalt heaped over each other, on which the fig tree with its dark green foliage formed a shady bower, most delightful during the heat of the day. The hills were composed of a lamellar granite, approaching the stratified appearance of gneiss, but the leaflets of mica, instead of forming continuous layers, were scattered. The east side of the narrow watercourse was of primitive rock, the west side basaltic. Having passed over the hills, I made the river at their east side. Its banks were open for access as far as the primitive rock extended, but another field of lava commenced higher up, and rendered any progress with our cattle impossible.

A native low shrubby Mulberry was found in this scrub, the fruit of which was good to eat, but of very small size.

From the top of the hills I enjoyed a most beautiful view of the valley of the river, with its large lagoons covered with Nymphaeas and Damasoniums. On one of the lagoons, Charley shot a Parra gallinacea, a bird which Mr. Gilbert had observed only at Port Essington. A well beaten path of the natives showed that they were numerous in this part of the country: we saw many of their camping places during the stage; and the fires of their camps were numerous; we saw a party of them, but they were too frightened to allow us to approach. Our latitude was 18 degrees 44 minutes 48 seconds. Our course was about N.N.W.

May 4.—We ascended the basaltic ridges, and reaching the table land, found it perfectly level, openly timbered, well grassed, but occasionally stony, by which our poor foot-sore bullocks suffered severely. About five miles north-west by west from our camp, we discovered an extensive valley with large lagoons and lakes, and a most luxuriant vegetation, bounded by blue distant ranges, and forming the most picturesque landscape we had yet met with. A chain of lagoons connected by a reedy brook followed the outlines of the table land, along the foot of its steep slopes. We descended by a tolerably gentle slope into the valley, and encamped near the reedy brook, which must be the same as that on which, lower down, our last camp was formed. Water, grass, hills, mountains, plains, forest land; all the elements of a fine pasturing country, were here united.

During one of the last stages, we discovered a leguminous tree, with the dark fissured bark of the Ironbark, but with large bipinnate leaves, the leaflets oblong, an inch in length; the pods broad and thin, and two or three inches long: this tree is common all over the northern part of the continent, and was found growing abundantly around Victoria, the principal settlement of Port Essington.

Mr. Roper and Brown, upon an excursion after ducks, which were very numerous on the lagoons, met with Blackfellows, who were willing to accost Brown, but could not bear the sudden sight of a white face. In trying to cross the valley, my course was intercepted every way by deep reedy and sedgy lagoons, which rendered my progress impossible. I saw, however, that this valley was also floored with a sheet of lava hollowed out into numerous deep basins, in which the water collected and formed the lagoons.

May 5.—I went with Charley to reconnoitre the upper part of the reedy brook, with a view to find a passage over the table land to the westward; at the same time I sent Mr. Roper and Brown to trace the river through the lagoons, and to examine whether there was any connection between them. I followed the base of the basaltic table land, along which the brook came down, and, after a two miles' ride on its banks, through oak trees, low fern trees, and several bush trees, found that it came down a valley deeply cut into the table land. The floor of the valley was of basaltic rock, and its steep slopes were covered with boulders of the same formation. The water ran in two distinct beds through the fissures, hollows, and caves of the rock. As our horses could not travel over the sharp edges of the rock without injuring their feet, we ascended the table land, and rode to the northward about four miles, and then came on plains, in which we distinguished a meandering band of green verdure, which proved to be the same brook we had left, or one of its head waters. We followed it through a series of plains, from one of which a blue mountain was visible to the north-west. I called it "Mount Lang," after Dr. Lang, the distinguished historiographer of New South Wales. Smoke was seen to the westward. At the right side of the brook, a stream of lava bounded the plains, and was, as usual, covered with dense scrub. Box, with occasional patches of narrow-leaved tea trees, grew along the plains. The forest was very open, and principally consisted of narrow-leaved Ironbark; the grass in the forest and on the plains, was of the best description. Finer stations for the squatter cannot exist.

May 6.—Following the brook about four miles farther, I came to its source at a gentle slope of basalt. Plains stretched along both sides of its course, and even beyond it. Luxuriant reeds, Plothos, and several deep green trees, crowded round its head. Kangaroos, which abounded particularly along the scrub, had formed numerous paths through the high grass to the water's edge. I now directed my course to the W.N.W., but soon found myself checked by a dyke or wall of basaltic lava, composed of boulders and tabular blocks heaped over each other in wild confusion, and covered by scrub; it stretched from N.W. to S.E. I travelled round its edge to the southward, after having made a vain attempt to cross it. The outlines of the stream ran out in low heads into the flat table land, and there we met occasionally with springs and chains of water-holes which united lower down into a water-course, which, after following alternately the outline of the scrub, and turning into the stream of lava, became lost among its loose rocks. The lava was very cellular; the basalt of the table land solid. The whole appearance of this interesting locality showed that the stream of lava was of much more recent date than the rock of the table land, and that the latter was probably formed under water, whilst the cellular scorified lava was poured out into the open air. The stream of lava enlarged so much, and descended into so broad a valley, that I considered it to be the head of the Burdekin. I walked across it, in order to ascertain the presence of water, but found nothing but deep dry hollows surrounded with drooping tea trees, and the black basaltic rocks covered with wild bottle-tree scrub. It joined the valley of lagoons very much like the valley of the reedy brook, and seemed to unite with the latter, and to expand all over the large basin. Numerous headlands protruded from the table land into the valley of lagoons, between the stream of lava and reedy brook. Many of them were composed of quartzite and pegmatite [Graphic granite, composed of quartz and laminated felspar.—ED.], the detritus of which formed sandy slopes very different from the black and loamy soil of the table land and its plains. Several isolated hills and short ridges rise out of the basaltic floor of the valley of lagoons; they are composed of a different rock; and if it may be allowed me to judge by the colour and by analogy, I should say that they were pegmatite and quartzite. It would, therefore, appear that the valley of lagoons is connected with three streams of lava; one following down the river to the southward, a second coming down the valley of Reedy Brook from W.N.W., and the third coming from the N.W. The course of the Burdekin has no connection with this valley, but runs apparently along its eastern side, and divides the primitive rocks from the streams of lava; for I had not observed any lava on its left bank.

In returning to our camp, we saw a great number of women and children, who ran away upon seeing us, screaming loudly, which attracted some young men to the spot, who were much bolder and approached us. I dismounted and walked up within five yards of them, when I stopped short from a mutual disinclination for too close quarters, as they were armed with spears and waddies. They made signs for me to take off my hat, and to give them something; but, having nothing with me, I made a sign that I would make them a present upon returning to the camp. They appeared to be in no way unfriendly, and directed us how to avoid the water. When I reached the camp, I found that the Blackfellows had been there already, and had been rather urgent to enter it, probably in consequence of the small number of my companions then present, who, however, managed to keep them in good humour by replying to their inquiries respecting our nature and intentions; among which one of the most singular was, whether the bullocks were not our gins. This occurred last night; in the morning they returned again in great numbers, and climbed the trees on the other side of the brook to observe what was doing within the camp. It now became necessary to show them our superiority; which we attempted to do by shooting at a kite, numbers of which were perched on the neighbouring trees; our shots, however, unfortunately missed, and the natives answered the discharge of the gun with a shout of laughter. At this time, however, Mr. Roper, Charley, and myself returned from our excursion, when they became quiet. I threw a tin canister over to them, and they returned me a shower of roasted Nymphaea fruit. It seems that the seed-vessels of Nymphaea and its rhizoma form the principal food of the natives; the seeds contain much starch and oil, and are extremely nourishing. I then gave them some pieces of dried meat, intimating by signs that it must be grilled; soon afterwards they retired. Mr. Roper came in with sad tidings; in riding up the steep bank of the river, his horse, unable to get a footing among the loose rocks, had fallen back and broken its thigh. I immediately resolved upon going to the place where the accident had happened, and proposed to my companions, that we should try to make the best of the meat, as the animal was young and healthy, and the supply would greatly assist in saving our bullocks to the end of our long journey; and they declared themselves willing at all events to give a fair trial to the horse-flesh. Our bullocks were foot-sore and required rest. We, therefore, shot the horse, skinned and quartered it the same night; and ate its liver and kidneys, which were quite as good as those of a bullock.
