29th.—The road continued along the river, and in the course of the day Mount St. Helens, another snowy peak of the Cascade range, was visible. We crossed the Umatilah river at a fall near its mouth. This stream is of the same class as the Walahwalah river, with a bed of volcanic rock, in places split into fissures. Our encampment was similar to that of yesterday; there was very little grass, and no wood. The Indians brought us some pieces for sale, which were purchased to make our fires.

31st.—By observation, our camp is in latitude 45 deg. 50' 05", and longitude 119 deg. 22' 18". The night has been cold, and we have white frost this morning, with a temperature at daylight of 25 deg., and at sunrise of 24 deg.. The early morning was very clear, and the stars bright; but, as usual, since we are on the Columbia, clouds formed immediately with the rising sun. The day continued fine, the east being covered with scattered clouds, but the west remaining clear, showing the remarkable cone-like peak of Mount Hood brightly drawn against the sky. This was in view all day in the southwest, but no other peaks of the range were visible. Our road was a bad one, of very loose, deep sand. We met on the way a party of Indians unusually well-dressed. They appeared intelligent, and, in our slight intercourse, impressed me with the belief that they possessed some aptitude for acquiring languages.

We continued to travel along the river, the stream being interspersed with many sand-bars (it being the season of low water) and with many islands, and an apparently good navigation. Small willows were the only wood; rock and sand the prominent geological feature. The rock of this section is a very compact and tough basalt, occurring in strata which have the appearance of being broken into fragments, assuming the form of columnar hills, and appearing always in escarpments, with the broken fragments strewed at the base and over the adjoining country.

We made a late encampment on the river, and used to-night the purshia tridentata for firewood. Among the rocks which formed the bank, was very good green grass. Latitude 45 deg. 44' 23", longitude 119 deg. 45' 09".



NOVEMBER.

1st.—Mount Hood is glowing in the sunlight this morning, and the air is pleasant, with a temperature of 38 deg.. We continued down the river, and, passing through a pretty green valley, bounded by high precipitous rocks, encamped at the lower end.

On the right shore, the banks of the Columbia are very high and steep; the river is 1,690 feet broad, and dark bluffs of rock give it a picturesque appearance.

2d.—The river here entered among bluffs, leaving no longer room for a road; and we accordingly left it, and took a more inland way among the river hills—on which we had no sooner entered, than we found a great improvement in the country. The sand had disappeared, and the soil was good, and covered with excellent grass, although the surface was broken into high hills, with uncommonly deep valleys. At noon we crossed John Day's river, a clear and beautiful stream, with a swift current and a bed of rolled stones. It is sunk in a deep valley, which is characteristic of all the streams in this region; and the hill we descended to reach it well deserves the name of mountain. Some of the emigrants had encamped on the river, and others at the summit of the farther hill, the ascent of which had probably cost their wagons a day's labor; and others again had halted for the night a few miles beyond, where they had slept without water. We also encamped in a grassy hollow without water; but, as we had been forewarned of this privation by the guide, the animals had all been watered at the river, and we had brought with us a sufficient quantity for the night.

3d.—After two hours' ride through a fertile, hilly country, covered, as all the upland here appears to be, with good green grass, we descended again into the river bottom, along which we resumed our sterile road, and in about four miles reached the ford of the Fall river, (Riviere aux Chutes,) a considerable tributary to the Columbia. We had heard, on reaching the Nez Perce fort, a repetition of the account in regard to the unsettled character of the Columbia Indians at the present time; and to our little party they had at various points manifested a not very friendly disposition, in several attempts to steal our horses. At this place I expected to find a badly-disposed band, who had plundered a party of 14 emigrant men a few days before, and taken away their horses; and accordingly we made the necessary preparation for our security, but happily met with no difficulty.

The river was high, divided into several arms, with a rocky island at its outlet into the Columbia, which at this place it rivalled in size, and apparently derived its highly characteristic name, which is received from one of its many falls some forty miles up the river. It entered the Columbia with a roar of falls and rapids, and is probably a favorite fishing station among the Indians, with whom both banks of the river were populous; but they scarcely paid any attention to us. The ford was very difficult at this time, and, had they entertained any bad intentions, they were offered a good opportunity to carry them out, as I drove directly into the river, and during the crossing the howitzer was occasionally several feet under water, and a number of the men appeared to be more often below than above. Our guide was well acquainted with the ford, and we succeeded in getting every thing safe over to the left bank. We delayed here only a short time to put the gun in order, and, ascending a long mountain hill, resumed our route again among the interior hills.

The roar of the Falls of the Columbia is heard from the heights, where we halted a few moments to enjoy a fine view of the river below. In the season of high water, it would be a very interesting object to visit, in order to witness what is related of the annual submerging of the fall under the waters which back up from the basin below, constituting a great natural lock at this place. But time had become an object of serious consideration; and the Falls, in their present state, had been seen and described by many.

After a day's journey of 17 miles, we encamped among the hills on a little clear stream, where, as usual, the Indians immediately gathered round us. Among them was a very old man, almost blind from age, with long and very white hair. I happened of my own accord to give this old man a present of tobacco, and was struck with the impression which my unpropitiated notice made on the Indians, who appeared in a remarkable manner acquainted with the real value of goods, and to understand the equivalents of trade. At evening, one of them spoke a few words to his people, and, telling me that we need entertain no uneasiness in regard to our animals, as none of them would be disturbed, they went all quietly away. In the morning, when they again came to the camp, I expressed to them the gratification we felt at their reasonable conduct, making them a present of some large knives and a few smaller articles.

4th.—The road continued among the hills, and, reaching an eminence, we saw before us, watered by a clear stream, a tolerably large valley, through which the trail passed.

In comparison with the Indians of the Rocky mountains and the great eastern plain, these are disagreeably dirty in their habits. Their huts were crowded with half-naked women and children, and the atmosphere within was any thing but pleasant to persons who had just been riding in the fresh morning air. We were somewhat amused with the scanty dress of a woman, who, in common with the others, rushed out of the huts on our arrival, and who, in default of other covering, used a child for a fig- leaf.

The road in about half an hour passed near an elevated point, from which we overlooked the valley of the Columbia for many miles, and saw in the distance several houses surrounded by fields, which a chief, who had accompanied us from the village, pointed out to us as the Methodist missionary station.

In a few miles we descended to the river, which we reached at one of its remarkably interesting features, known as the Dalles of the Columbia. The whole volume of the river at this place passed between the walls of a chasm, which has the appearance of having been rent through the basaltic strata which form the valley-rock of the region. At the narrowest place we found the breadth, by measurement, 58 yards, and the average height of the walls above the water 25 feet; forming a trough between the rocks—whence the name, probably applied by a Canadian voyageur. The mass of water, in the present low state of the river, passed swiftly between, deep and black, and curled into many small whirlpools and counter currents, but unbroken by foam, and so still that scarcely the sound of a ripple was heard. The rock, for a considerable distance from the river, was worn over a large portion of its surface into circular holes and well-like cavities, by the abrasion of the river, which, at the season of high waters, is spread out over the adjoining bottoms.

In the recent passage through this chasm, an unfortunate event had occurred to Mr. Applegate's party, in the loss of one of their boats, which had been carried under water in the midst of the Dalles, and two of Mr. Applegate's children and one man drowned. This misfortune was attributed only to want of skill in the steersman, as at this season there was no impediment to navigation; although the place is entirely impassable at high water, when boats pass safely over the great falls above, in the submerged state in which they then find themselves.

The basalt here is precisely the same as that which constitutes the rock of the valley higher up the Columbia, being very compact, with a few round cavities.

We passed rapidly three or four miles down the level valley and encamped near the mission. The character of the forest growth here changes, and we found ourselves, with pleasure, again among oaks and other forest-trees of the east, to which we had long been strangers; and the hospitable and kind reception with which we were welcomed among our country people at the mission, aided the momentary illusion of home.

Two good-looking wooden dwelling-houses, and a large schoolhouse, with stables, barn, and garden, and large cleared fields between the houses and the river bank, on which were scattered the wooden huts of an Indian village, gave to the valley the cheerful and busy air of civilization, and had in our eyes an appearance of abundant and enviable comfort.

Our land journey found here its western termination. The delay involved in getting our camp to the right bank of the Columbia, and in opening a road through the continuous forest to Vancouver, rendered a journey along the river impracticable; and on this side the usual road across the mountain required strong and fresh animals, there being an interval of three days in which they could obtain no food. I therefore wrote immediately to Mr. Fitzpatrick, directing him to abandon the carts at the Walahwalah missionary station, and, as soon as the necessary pack-saddles could be made, which his party required, meet me at the Dalles, from which point I proposed to commence our homeward journey. The day after our arrival being Sunday, no business could be done at the mission; but on Monday, Mr. Perkins assisted me in procuring from the Indians a large canoe, in which I designed to complete our journey to Vancouver, where I expected to obtain the necessary supply of provisions and stores for our winter journey. Three Indians, from the family to whom the canoe belonged, were engaged to assist in working her during the voyage, and, with them, our water party consisted of Mr. Preuss and myself, with Bernier and Jacob Dodson. In charge of the party which was to remain at the Dalles I left Carson, with instructions to occupy the people in making pack-saddles and refitting their equipage. The village from which we were to take the canoe was on the right bank of the river, about ten miles below, at the mouth of the Tinanens creek: and while Mr. Preuss proceeded down the river with the instruments, in a little canoe paddled by two Indians, Mr. Perkins accompanied me with the remainder of the party by land. The last of the emigrants had just left the Dalles at the time of our arrival, traveling some by water and others by land, making ark-like rafts, on which they had embarked their families and households, with their large wagons and other furniture, while their stock were driven along the shore.

For about five miles below the Dalles, the river is narrow, and probably very deep; but during this distance it is somewhat open, with grassy bottoms on the left. Entering, then, among the lower mountains of the Cascade range, it assumes a general character, and high and steep rocky hills shut it in on either side, rising abruptly in places, to the height of fifteen hundred feet above the water, and gradually acquiring a more mountainous character as the river approaches the Cascades.

After an hour's travel, when the sun was nearly down, we searched along the shore for a pleasant place, and halted to prepare supper. We had been well supplied by our friends at the mission with delicious salted salmon, which had been taken at the fattest season; also, with potatoes, bread, coffee, and sugar. We were delighted at a change in our mode of traveling and living. The canoe sailed smoothly down the river; at night we encamped upon the shore, and a plentiful supply of comfortable provisions supplied the first of wants. We enjoyed the contrast which it presented to our late toilsome marchings, our night watchings, and our frequent privation of food. We were a motley group, but all happy: three unknown Indians; Jacob, a colored man; Mr. Preuss, a German; Bernier, creole French; and myself.

Being now upon the ground explored by the South Sea expedition under Captain Wilkes, and having accomplished the object of uniting my survey with his, and thus presenting a connected exploration from the Mississippi to the Pacific, and the winter being at hand, I deemed it necessary to economize time by voyaging in the night, as is customary here, to avoid the high winds, which rise with the morning, and decline with the day.

Accordingly, after an hour's halt, we again embarked, and resumed our pleasant voyage down the river. The wind rose to a gale after several hours; but the moon was very bright, and the wind was fair, and the canoe glanced rapidly down the stream, the waves breaking into foam alongside; and our night voyage, as the wind bore us rapidly along between the dark mountains, was wild and interesting. About midnight we put to the shore on a rocky beach, behind which was a dark looking pine forest. We built up large fires among the rocks, which were in large masses round about; and, arranging our blankets on the most sheltered places we could find, passed a delightful night.

After an early breakfast, at daylight we resumed our journey, the weather being clear and beautiful, and the river smooth and still. On either side the mountains are all pine-timbered, rocky, and high. We were now approaching one of the marked features of the lower Columbia where the river forms a great cascade, with a series of rapids, in breaking through the range of mountains to which the lofty peaks of Mount Hood and St. Helens belong, and which rise as great pillars of snow on either side of the passage. The main branch of the Sacramento river, and the Tlamath, issue in cascades from this range; and the Columbia, breaking through it in a succession of cascades, gives the idea of cascades to the whole range; and hence the name of CASCADE RANGE, which it bears, and distinguishes it from the Coast Range lower down. In making a short turn to the south, the river forms the cascades in breaking over a point of agglomerated masses of rock, leaving a handsome bay to the right, with several rocky, pine-covered islands, and the mountains sweep at a distance around a cove where several small streams enter the bay. In less than an hour we halted on the left bank, about five minutes' walk above the cascades, where there were several Indian huts, and where our guides signified it was customary to hire Indians to assist in making the portage. When traveling with a boat as light as a canoe, which may easily be carried on the shoulders of the Indians, this is much the better side of the river for the portage, as the ground here is very good and level, being a handsome bottom, which I remarked was covered (as was now always the case along the river) with a growth of green and fresh- looking grass. It was long before we could come to an understanding with the Indians; but to length, when they had first received the price of their assistance in goods, they went vigorously to work; and, in a shorter time than had been occupied in making our arrangements, the canoe, instruments, and baggage, were carried through (a distance of about half a mile) to the bank below the main cascade, where we again embarked, the water being white with foam among ugly rocks, and boiling into a thousand whirlpools. The boat passed with great rapidity, crossing and recrossing in the eddies of the current. After passing through about two miles of broken water, we ran some wild-looking rapids, which are called the Lower Rapids, being the last on the river, which below is tranquil and smooth—a broad, magnificent stream. On a low broad point on the right bank of the river, at the lower end of these rapids, were pitched many tents of the emigrants, who were waiting here for their friends from above, or for boats and provisions which were expected from Vancouver. In our passage down the rapids, I had noticed their camps along the shore, or transporting their goods across the portage. This portage makes a head of navigation, ascending the river. It is about two miles in length; and above, to the Dalles, is 45 miles of smooth and good navigation.

We glided on without further interruption between very rocky and high steep mountains, which sweep along the river valley at a little distance, covered with forests of pine, and showing occasionally lofty escarpments of red rock. Nearer, the shore is bordered by steep escarped hills end huge vertical rocks, from which the waters of the mountain reach the river in a variety of beautiful falls, sometimes several hundred feet in height. Occasionally along the river occurred pretty bottoms, covered with the greenest verdure of the spring. To a professional farmer, however, it does not offer many places of sufficient extent to be valuable for agriculture; and after passing a few miles below the Dalles, I had scarcely seen a place on the south shore where wagons could get to the river. The beauty of the scenery was heightened by the continuance of very delightful weather, resembling the Indian summer of the Atlantic. A few miles below the cascades we passed a singular isolated hill; and in the course of the next six miles occurred five very pretty falls from the heights on the left bank, one of them being of a very picturesque character; and towards sunset we reached a remarkable point of rocks, distinguished, on account of prevailing high winds, and the delay it frequently occasions to the canoe navigation, by the name of Cape Horn. It borders the river in a high wall of rock, which comes boldly down into deep water; and in violent gales down the river, and from the opposite shore, which is the prevailing direction of strong winds, the water is dashed against it with considerable violence. It appears to form a serious obstacle to canoe traveling; and I was informed by Mr. Perkins, that in a voyage up the river he had been detained two weeks at this place, and was finally obliged to return to Vancouver.

The winds of this region deserve a particular study. They blow in currents, which show them to be governed by fixed laws; and it is a problem how far they may come from the mountains, or from the ocean through the breaks in the mountains which let out the river.

The hills here had lost something of their rocky appearance, and had already begun to decline. As the sun went down, we searched along the river for an inviting spot; and, finding a clean rocky beach, where some large dry trees were lying on the ground, we ran our boat to the shore; and, after another comfortable supper, ploughed our way along the river in darkness. Heavy clouds covered the sky this evening, and the wind began to sweep in gusts among the trees, as if bad weather were coming. As we advanced, the hills on both sides grew constantly lower; on the right, retreating from the shore, and forming a somewhat extensive bottom of intermingled prairie and wooded land. In the course of a few hours, and opposite to a small stream corning in from the north, called the Tea Prairie river, the highlands on the left declined to the plains, and three or four miles more disappeared entirely on both sides, and the river entered the low country. The river had gradually expanded; and when we emerged from the highlands, the opposite shores were so distant as to appear indistinct in the uncertainty of the light. About ten o'clock our pilots halted, apparently to confer about the course; and, after a little hesitation, pulled directly across an open expansion of the river, where the waves were somewhat rough for a canoe, the wind blowing very fresh. Much to our surprise, a few minutes afterwards we ran aground. Backing off our boat, we made repeated trials at various places to cross what appeared to be a point of shifting sand-bars, where we had attempted to shorten the way by a cut-off. Finally, one of our Indians got into the water, and waded about until he found a channel sufficiently deep, through which we wound along after him, and in a few minutes again entered the deep water below. As we paddled rapidly down the river, we heard the noise of a saw-mill at work on the right bank; and, letting our boat float quietly down, we listened with pleasure to the unusual sounds, and before midnight, encamped on the bank of the river, about a mile above Fort Vancouver. Our fine dry weather had given place to a dark cloudy night. At midnight it began to rain; and we found ourselves suddenly in the gloomy and humid season, which, in the narrow region lying between the Pacific and the Cascade mountains, and for a considerable distance along the coast, supplies the place of winter.

In the morning, the first object that attracted my attention was the barque Columbia, lying at anchor near the landing. She was about to start on a voyage to England, and was now ready for sea; being detained only in waiting the arrival of the express bateaux, which descend the Columbia and its north fork with the overland mail from Canada and Hudson's Bay, which had been delayed beyond the usual time. I immediately waited upon Dr. McLaughlin, the executive officer of the Hudson Bay Company, in the territory west of the Rocky mountains, who received me with the courtesy and hospitality for which he has been eminently distinguished, and which makes a forcible and delightful impression on a traveler from the long wilderness from which we had issued. I was immediately supplied by him with the necessary stores and provisions to refit and support my party in our contemplated winter journey to the States; and also with a Mackinaw boat and canoes, manned with Canadian and Iroquois voyageurs and Indians, for their transportation to the Dalles of the Columbia. In addition to this efficient kindness in furnishing me with these necessary supplies, I received from him a warm and gratifying sympathy in the suffering which his great experience led him to anticipate for us in our homeward journey, and a letter of recommendation and credit for any officers of the Hudson Bay Company into whose posts we might be driven by unexpected misfortune.

Of course, the future supplies for my party were paid for, bills on the Government of the United States being readily taken; but every hospitable attention was extended to me, and I accepted an invitation to take a room in the fort, "and to make myself at home while I stayed."

I found many American emigrants at the fort; others had already crossed the river into their land of promise—the Walahmette valley. Others were daily arriving; and all of them have been furnished with shelter, so far as it could be afforded by the buildings connected with the establishment. Necessary clothing and provisions (the latter to be returned in kind from the produce of their labor) were also furnished. This friendly assistance was of very great value to the emigrants, whose families were otherwise exposed to much suffering in the winter rains, which had now commenced; at the same time they were in want of all the common necessaries of life. Those who had taken a water conveyance at the Nez Perce fort continued to arrive safely, with no other accident than has been already mentioned. The party which had crossed over the Cascade mountains were reported to have lost a number of their animals; and those who had driven their stock down the Columbia had brought them safely in, and found for them a ready and very profitable market, and were already proposing to return to the States in the spring for another supply. In the space of two days our preparations had been completed, and we were ready to set out on our return. It would have been very gratifying to have gone down to the Pacific, and, solely in the interest and love of geography, to have seen the ocean on the western as well as on the eastern side of the continent, so as to give a satisfactory completeness to the geographical picture which had been formed in our minds; but the rainy season had now regularly set in, and the air was filled with fogs and rain, which left no beauty in any scenery, and obstructed observations. The object of my instructions had been entirely fulfilled in having connected our reconnoissance with the surveys of Captain Wilkes; and although it would have been agreeable and satisfactory to terminate here also our ruder astronomical observations, I was not, for such a reason, justified to make a delay in waiting for favorable weather.

Near sunset of the 10th, the boats left the fort, and encamped after making only a few miles. Our flotilla consisted of a Mackinaw barge and three canoes—one of them that in which we had descended the river; and a party in all of twenty men. One of the emigrants, Mr. Burnet, of Missouri, who had left his family and property at the Dalles, availed himself of the opportunity afforded by the return of our boats to bring them down to Vancouver. This gentleman, as well as the Messrs. Applegate, and others of the emigrants whom I saw, possessed intelligence and character, with the moral and intellectual stamina, as well as the enterprise, which give solidity and respectability to the foundation of colonies.

11th.—The morning was rainy and misty. We did not move with the practised celerity of my own camp; and it was nearly nine o'clock when our motley crew had finished their breakfast and were ready to start. Once afloat, however, they worked steadily and well, and we advanced at a good rate up the river; and in the afternoon a breeze sprung up, which enabled us to add a sail to the oars. At evening we encamped on a warm-looking beach, on the right bank, at the foot of the high river-hill, immediately at the lower end of Cape Horn. On the opposite shore is said to be a singular hole in the mountain, from which the Indians believe comes the wind producing these gales. It is called the Devil's hole; and the Indians, I was told, had been resolving to send down one of their slaves to explore the region below. At dark, the wind shifted into its stormy quarter, gradually increasing to a gale from the southwest; and the sky becoming clear, I obtained a good observation of an emersion of the first satellite; the result of which being an absolute observation, I have adopted for the longitude of the place.

12th.—The wind during the night had increased to so much violence that the broad river this morning was angry and white; the waves breaking with considerable force against this rocky wall of the cape. Our old Iroquois pilot was unwilling to risk the boats around the point, and I was not disposed to hazard the stores of our voyage for the delay of a day. Further observations were obtained during the day, giving for the latitude of the place 45 deg. 33' 09"; and the longitude obtained from the satellite is 122 deg. 6' 15".

13th.—We had a day of disagreeable and cold rain and, late in the afternoon, began to approach the rapids of the cascades. There is here a high timbered island on the left shore, below which, in descending, I had remarked, in a bluff of the river, the extremities of trunks of trees, appearing to be imbedded in the rock. Landing here this afternoon, I found, in the lower part of the escarpment, a stratum of coal and forest- trees, imbedded between strata of altered clay, containing the remains of vegetables, the leaves of which indicate that the plants wore dicotyledonous. Among these, the stems of some of the ferns are not mineralized, but merely charred, retaining still their vegetable structure and substance; and in this condition a portion of the trees remain. The indurated appearance and compactness of the strata, as well, perhaps, as the mineralized condition of the coal, are probably due to igneous action. Some portions of the coal precisely resemble in aspect the canal coal of England, and, with the accompanying fossils, have been referred to the tertiary formation.

These strata appear to rest upon a mass of agglomerated rock, being but a few feet above the water of the river; and over them is the escarpment of perhaps 80 feet, rising gradually in the rear towards the mountains. The wet and cold evening, and near approach of night, prevented me from making any other than a slight examination.

The current was now very swift, and we were obliged to cordelle the boat along the left shore, where the bank was covered with large masses of rocks. Night overtook us at the upper end of the island, a short distance below the cascades, and we halted on the open point. In the mean time, the lighter canoes, paddled altogether by Indians, had passed ahead, and were out of sight. With them was the lodge, which was the only shelter we had, with most of the bedding and provisions. We shouted, and fired guns; but all to no purpose, as it was impossible for them to hear above the roar of the river; and we remained all night without shelter, the rain pouring down all the time. The old voyageurs did not appear to mind it much, but covered themselves up as well as they could, and lay down on the sand- beach, where they remained quiet until morning. The rest of us spent a rather miserable night; and, to add to our discomfort, the incessant rain extinguished our fires; and we were glad when at last daylight appeared, and we again embarked.

Crossing to the right bank, we cordelled the boat along the shore, there being no longer any use of the paddles, and put into a little bay below the upper rapids. Here we found a lodge pitched, and about 20 Indians sitting around a blazing fire within, making a luxurious breakfast with salmon, bread, butter, sugar, coffee, and other provisions. In the forest, on the edge of the high bluff overlooking the river, is an Indian graveyard, consisting of a collection of tombs, in each of which were the scattered bones of many skeletons. The tombs were made of boards, which were ornamented with many figures of men and animals of the natural size— from their appearance, constituting the armorial device by which, among Indians, the chiefs are usually known.

The masses of rock displayed along the shores of the ravine in the neighborhood of the cascades, are clearly volcanic products. Between this cove, which I called Graveyard bay, and another spot of smooth water above, on the right, called Luders bay, sheltered by a jutting point of huge rocky masses at the foot of the cascades, the shore along the intervening rapids is lined with precipices of distinct strata of red and variously-colored lavas, in inclined positions.

The masses of rock forming the point at Luders bay consist of a porous trap, or basalt—a volcanic product of a modern period. The rocks belong to agglomerated masses, which form the immediate ground of the cascades, and have been already mentioned as constituting a bed of cemented conglomerate rocks, appearing at various places along the river. Here they are scattered along the shores, and through the bed of the river, wearing the character of convulsion, which forms the impressive and prominent feature of the river at this place.

Wherever we came in contact with the rocks of these mountains, we found them volcanic, which is probably the character of the range; and at this time, two of the great snowy cones, Mount Regnier and St. Helens, were in action. On the 23d of the preceding November, St. Helens had scattered its ashes, like a white fall of snow, over the Dalles of the Columbia, 50 miles distant. A specimen of these ashes was given to me by Mr. Brewer, one of the clergymen at the Dalles.

The lofty range of the Cascade mountains forms a distinct boundary between the opposite climates of the regions along its western and eastern bases. On the west, they present a barrier to the clouds of fog and rain which roll up from the Pacific ocean and beat against their rugged sides, forming the rainy season of the winter in the country along the coast. Into the brighter skies of the region along their eastern base, this rainy winter never penetrates; and at the Dalles of the Columbia the rainy season is unknown, the brief winter being limited to a period of about two months, during which the earth is covered with the slight snows of a climate remarkably mild for so high a latitude. The Cascade range has an average distance of about 130 miles from the sea-coast. It extends far both north and south of the Columbia, and is indicated to the distant observer, both in course and position, by the lofty volcanic peaks which rise out of it, and which are visible to an immense distance.

During several days of constant rain, it kept our whole force laboriously employed in getting our barge and canoes to the upper end of the Cascades. The portage ground was occupied by emigrant families; their thin and insufficient clothing, bareheaded and barefooted children, attesting the length of their journey, and showing that they had, in many instances, set out without a due preparation of what was indispensable.

A gentleman named Luders, a botanist from the city of Hamburg, arrived at the bay I have called by his name while we were occupied in bringing up the boats. I was delighted to meet at such a place a man of kindred pursuits; but we had only the pleasure of a brief conversation, as his canoe, under the guidance of two Indians, was about to run the rapids; and I could not enjoy the satisfaction of regaling him with a breakfast, which, after his recent journey, would have been an extraordinary luxury. All of his few instruments and baggage were in the canoe, and he hurried around by land to meet it at the Graveyard bay; but he was scarcely out of sight, when, by the carelessness of the Indians, the boat was drawn into the midst of the rapids, and glanced down the river, bottom up, with a loss of every thing it contained. In the natural concern I felt for his misfortune, I gave to the little cove the name of Luders bay.

15th.—We continued to-day our work at the portage.

About noon, the two barges of the express from Montreal arrived at the upper portage landing, which, for large boats, is on the right bank of the river. They were a fine-looking crew, and among them I remarked a fresh- looking woman and her daughter, emigrants from Canada. It was satisfactory to see the order and speed with which these experienced water-men effected the portage, and passed their boats over the cascades. They had arrived at noon, and in the evening they expected to reach Vancouver. These bateaux carry the express of the Hudson Bay Company to the highest navigable point of the North Fork of the Columbia, whence it is carried by an overland party to Lake Winipec, where it is divided; part going to Montreal, and part to Hudson Bay. Thus a regular communication is kept up between three very remote points.

The Canadian emigrants were much chagrined at the change of climate, and informed me that, only a few miles above, they had left a country of bright blue sky and a shining sun. The next morning the upper parts of the mountains which directly overlook the cascades, were white with the freshly fallen snow, while it continued to rain steadily below.

Late in the afternoon we finished the portage, and, embarking again, moved a little distance up the right bank, in order to clear the smaller rapids of the cascades, and have a smooth river for the next morning. Though we made but a few miles, the weather improved immediately; and though the rainy country and the cloudy mountains were close behind, before us was the bright sky; so distinctly is climate here marked by a mountain boundary.

17th.—We had to-day an opportunity to complete the sketch of that portion of the river down which we had come by night.

Many places occur along the river, where the stumps, or rather portions of the trunks of pine-trees, are standing along the shore, and in the water, where they may be seen at a considerable depth below the surface, in the beautifully clear water. These collections of dead trees are called on the Columbia the submerged forest, and are supposed to have been created by the effects of some convulsion which formed the cascades, and which, by damming up the river, placed these trees under water and destroyed them. But I venture to presume that the cascades are older than the trees; and as these submerged forests occur at five or six places along the river, I had an opportunity to satisfy myself that they have been formed by immense landslides from the mountains, which here closely shut in the river, and which brought down with them into the river the pines of the mountain. At one place, on the right bank, I remarked a place where a portion of one of these slides seemed to have planted itself, with all the evergreen foliage, and the vegetation of the neighboring hill, directly amidst the falling and yellow leaves of the river trees. It occurred to me that this would have been a beautiful illustration to the eye of a botanist.

Following the course of a slide, which was very plainly marked along the mountain, I found that in the interior parts the trees were in their usual erect position; but at the extremity of the slide they were rocked about, and thrown into a confusion of inclinations.

About 4 o'clock in the afternoon we passed a sandy bar in the river, whence we had an unexpected view of Mount Hood, bearing directly south by compass.

During the day we used oar and sail, and at night had again a delightful camping ground, and a dry place to sleep upon.

18th.—The day again was pleasant and bright. At 10 o'clock we passed a rock island, on the right shore of the river, which the Indians use as a burial ground; and halting for a short time, about an hour afterwards, at the village of our Indian friends, early in the afternoon we arrived again at the Dalles.

Carson had removed the camp up the river a little nearer to the hills, where the animals had better grass. We found every thing in good order, and arrived just in time to partake of an excellent roast of California beef. My friend, Mr. Gilpin, had arrived in advance of the party. His object in visiting this country had been to obtain correct information of the Walahmette settlements; and he had reached this point in his journey, highly pleased with the country over which he had traveled, and with invigorated health. On the following day he continued his journey, in our returning boats, to Vancouver.

The camp was now occupied in making the necessary preparations for our homeward journey, which, though homeward, contemplated a new route, and a great circuit to the south and southeast, and the exploration of the Great Basin between the Rocky mountains and the Sierra Nevada. Three principal objects were indicated, by report or by maps, as being on this route; the character or existence of which I wished to ascertain and which I assumed as landmarks, or leading points, on their projected line of return. The first of those points was the Tlamath lake, on the table-land between the head of Fall river, which comes to the Columbia, and the Sacramento, which goes to the Bay of San Francisco; and from which lake a river of the same name makes its way westwardly direct to the ocean. This lake and river are often called Klamet, but I have chosen to write its name according to the Indian pronunciation. The position of this lake, on the line of inland communication between Oregon and California; its proximity to the demarcation boundary of latitude 42 deg.; its imputed double character of lake, or meadow, according to the season of the year; and the hostile and warlike character attributed to the Indians about it—all made it a desirable object to visit and examine. From this lake our course was intended to be about southeast, to a reported lake called Mary's, at some days' journey in the Great Basin; and thence, still on southeast, to the reputed Buenaventura river, which has had a place in so many maps, and countenanced the belief of the existence of a great river flowing from the Rocky mountains to the Bay of San Francisco. From the Buenaventura the next point was intended to be in that section of the Rocky mountains which includes the heads of Arkansas river, and of the opposite waters of the Californian gulf; and thence down the Arkansas to Bent's fort, and home. This was our projected line of return—a great part of it absolutely new to geographical, botanical, and geological science—and the subject of reports in relation to lakes, rivers, deserts, and savages hardly above the condition of mere wild animals, which inflamed desire to know what this terra incognita really contained.

It was a serious enterprise, at the commencement of winter, to undertake the traverse of such a region, and with a party consisting only of twenty- five persons, and they of many nations—American, French, German, Canadian, Indian, and colored—and most of those young, several being under twenty-one years of age. All knew that a strange country was to be explored, and dangers and hardships to be encountered; but no one blenched at the prospect. On the contrary, courage and confidence animated the whole party. Cheerfulness, readiness, subordination, prompt obedience, characterized all; nor did any extremity of peril and privation, to which we were afterwards exposed, ever belie, or derogate from, the fine spirit of this brave and generous commencement. The course of the narrative will show at what point, and for what reasons, we were prevented from the complete execution of this plan, after having made considerable progress upon it, and how we were forced by desert plains and mountain ranges, and deep snows, far to the south, and near to the Pacific ocean, and along the western base of the Sierra Nevada, where, indeed, a new and ample field of exploration opened itself before us. For the present, we must follow the narrative, which will first lead us south along the valley of Fall river, and the eastern base of the Cascade range, to the Tlamath lake, from which, or its margin, three rivers go in three directions—one west, to the ocean; another north, to the Columbia; the third south, to California.

For the support of the party, I had provided at Vancouver a supply of provisions for not less than three months, consisting principally of flour, peas, and tallow—the latter being used in cooking; and, in addition to this, I had purchased at the mission some California cattle, which were to be driven on the hoof. We had 104 mules and horses—part of the latter procured from the Indians about the mission; and for the sustenance of which, our reliance was upon the grass which we should find, and the soft porous wood which was to be substituted when there was none.

Mr. Fitzpatrick, with Mr. Talbot and the remainder of the party, arrived on the 21st; and the camp was now closely engaged in the labor of preparation. Mr. Perkins succeeded in obtaining as a guide to the Tlamath lake two Indians—one of whom had been there, and bore the marks of several wounds he had received from some of the Indians in the neighborhood; and the other went along for company. In order to enable us to obtain horses, he dispatched messengers to the various Indian villages in the neighborhood, informing them that we were desirous to purchase, and appointing a day for them to bring them in.

We made, in the mean time, several excursions in the vicinity. Mr. Perkins walked with Mr. Preuss and myself to the heights, about nine miles distant, on the opposite side of the river, whence, in fine weather, an extensive view may be had over the mountains, including seven great peaks of the Cascade range; but clouds, on this occasion, destroyed the anticipated pleasure, and we obtained bearings only to three that were visible—Mount Regnier, St. Helens, and Mount Hood. On the heights, about one mile south of the mission, a very fine view may be had of Mount Hood and St. Helens. In order to determine their position with as much accuracy as possible, the angular distances of the peaks were measured with the sextant, at different fixed points from which they could be seen.

The Indians brought in their horses at the appointed time, and we succeeded in obtaining a number in exchange for goods; but they were relatively much higher here, where goods are plenty and at moderate prices, than we had found them in the more eastern part of our voyage. Several of the Indians inquired very anxiously to know if we had any dollars; and the horses we procured were much fewer in number than I had desired, and of thin, inferior quality; the oldest and poorest being those that were sold to us. These horses, as ever in our journey you will have occasion to remark, are valuable for hardihood and great endurance.

24th.—At this place one of the men was discharged; and at the request of Mr. Perkins, a Chinook Indian, a lad of nineteen, who was extremely desirous to "see the whites," and make some acquaintance with our institutions, was received into the party under my special charge, with the understanding that I would again return him to his friends. He had lived for some time in the household of Mr. Perkins, and spoke a few words of the English language.

25th.—We were all up early, in the excitement of turning towards home. The stars were brilliant, and the morning cold, the thermometer at daylight 26 deg..

Our preparations had been fully completed, and to-day we commenced our journey. The little wagon which had hitherto carried the instruments, I judged it necessary to abandon; and it was accordingly presented to the mission. In all our long traveling, it had never been overturned or injured by any accident of the road; and the only things broken were the glass lamps, and one of the front panels, which had been kicked out by an unruly Indian horse. The howitzer was the only wheeled carriage now remaining. We started about noon, when the weather had become disagreeably cold, with flurries of snow. Our friend Mr. Perkins, whose kindness had been active and efficient during our stay, accompanied us several miles on our road, when he bade us farewell, and consigned us to the care of our guides. Ascending to the uplands beyond the southern fork of the Tinanens creek, we found the snow lying on the ground in frequent patches, although the pasture appeared good, and the new short grass was fresh and green. We traveled over high, hilly land, and encamped on a little branch of Tinanens creek, where there were good grass and timber. The southern bank was covered with snow, which was scattered over the bottom; and the little creek, its borders lined with ice, had a chilly and wintry look. A number of Indians had accompanied us so far on our road, and remained with us during the night. Two bad-looking fellows, who were detected in stealing, were tied and laid before the fire, and guard mounted over them during the night. The night was cold, and partially clear.

26th.—The morning was cloudy and misty, and but a few stars visible. During the night water froze in the tents, and at sunrise the thermometer was at 20 deg.. Left camp at 10 o'clock, the road leading along tributaries of the Tinanens, and being, so far, very good. We turned to the right at the fork of the trail, ascending by a steep ascent along a spur to the dividing grounds between this stream and the waters of Fall river. The creeks we had passed were timbered principally with oak and other deciduous trees. Snow lies everywhere here on the ground, and we had a slight fall during the morning; but towards noon the bright sky yielded to a bright sun.

This morning we had a grand view of St. Helens and Regnier: the latter appeared of a conical form, and very lofty, leading the eye far up into the sky. The line of the timbered country is very distinctly marked here, the bare hills making with it a remarkable contrast. The summit of the ridge commanded a fine view of the Taih prairie, and the stream running through it, which is a tributary to the Fall river, the chasm of which is visible to the right. A steep descent of a mountain hill brought us down into the valley, and we encamped on the stream after dark, guided by the light of fires, which some naked Indians, belonging to a village on the opposite side, were kindling for us on the bank. This is a large branch of the Fall river. There was a broad band of thick ice some fifteen feet wide on either bank, and the river current is swift and bold. The night was cold and clear, and we made our astronomical observation this evening with the thermometer at 20 deg..

In anticipation of coming hardship, and to spare our horses, there was much walking done to-day; and Mr. Fitzpatrick and myself made the day's journey on foot. Somewhere near the mouth of this stream are the falls from which the river takes its name.

27th.—A fine view of Mount Hood this morning; a rose-colored mass of snow, bearing S. 85 deg. W. by compass. The sky is clear, and the air cold; the thermometer 2.5 deg. below zero, the trees and bushes glittering white, and the rapid stream filled with floating ice.

Stiletsi and the White Crane, two Indian chiefs who had accompanied us thus far, took their leave, and we resumed our journey at 10 o'clock. We ascended by a steep hill from the river bottom, which is sandy, to a volcanic plain, around which lofty hills sweep in a regular form. It is cut up by gullies of basaltic rock, escarpments of which appear everywhere in the hills. This plain is called the Taih prairie, and is sprinkled with some scattered pines. The country is now far more interesting to a traveler than the route along the Snake and Columbia rivers. To our right we had always the mountains, from the midst of whose dark pine forests the isolated snowy peaks were looking out like giants. They served us for grand beacons to show the rate at which we advanced in our journey. Mount Hood was already becoming an old acquaintance, and, when we ascended the prairie, we obtained a bearing to Mount Jefferson, S. 23 deg. W. The Indian superstition has peopled these lofty peaks with evil spirits, and they have never yet known the tread of a human foot. Sternly drawn against the sky, they look so high and steep, so snowy and rocky, that it appears almost impossible to climb them; but still a trial would have its attractions for the adventurous traveler. A small trail takes off through the prairie, towards a low point in the range, and perhaps there is here a pass into the Wahlamette valley. Crossing the plain, we descended by a rocky hill into the bed of a tributary of Fall river, and made an early encampment. The water was in holes, and frozen over; and we were obliged to cut through the ice for the animals to drink. An ox, which was rather troublesome to drive, was killed here for food.

The evening was fine, the sky being very clear, and I obtained an immersion of the third satellite, with a good observation of an emersion of the first; the latter of which gives for the longitude, 121 deg. 02' 43"; the latitude, by observation, being 45 deg. 06' 45". The night was cold—the thermometer during the observations standing at 9 deg..

28th.—The sky was clear in the morning, but suddenly clouded over, and at sunrise it began to snow, with the thermometer at 18 deg..

We traversed a broken high country, partly timbered with pine, and about noon crossed a mountainous ridge, in which, from the rock occasionally displayed, the formation consists of compact lava. Frequent tracks of elk were visible in the snow. On our right, in the afternoon, a high plain, partially covered with pine, extended about ten miles, to the foot of the Cascade mountains.

At evening we encamped in a basin narrowly surrounded by rocky hills, after a day's journey of twenty-one miles. The surrounding rocks are either volcanic products, or highly altered by volcanic action, consisting of quartz and reddish-colored silicious masses.

29th.—We emerged from the basin, by a narrow pass, upon a considerable branch of Fall river, running to the eastward through a narrow valley. The trail, descending this stream, brought us to a locality of hot springs, which were on either bank. Those on the left, which were formed into deep handsome basins, would have been delightful baths, if the outer air had not been so keen, the thermometer in these being at 89 deg.. There were others on the opposite side, at the foot of an escarpment, in which the temperature of the water was 134 deg.. These waters deposited around the spring a brecciated mass of quartz and feldspar, much of it of a reddish color.

We crossed the stream here, and ascended again to a high plain, from an elevated point of which we obtained a view of six of the great peaks— Mount Jefferson, followed to the southward by two others of the same class; and succeeding, at a still greater distance to the southward, were three other lower peaks, clustering together in a branch ridge. These, like the great peaks, were snowy masses, secondary only to them; and, from the best examination our time permitted, we are inclined to believe that the range to which they belong is a branch from the great chain which here bears to the westward. The trail, during the remainder of the day, followed near to the large stream on the left, which was continuously walled in between high rocky banks. We halted for the night on a little by-stream.

30th.—Our journey to-day was short. Passing over a high plain, on which were scattered cedars, with frequent beds of volcanic rock in fragments interspersed among the grassy grounds, we arrived suddenly on the verge of the steep and rocky descent to the valley of the stream we had been following, and which here ran directly across our path, emerging from the mountains on the right. You will remark that the country is abundantly watered with large streams, which pour down from the neighboring range.

These streams are characterized by the narrow and chasm-like valleys in which they run, generally sunk a thousand feet below the plain. At the verge of this plain, they frequently commence in vertical precipices of basaltic rock, and which leave only casual places at which they can be entered by horses. The road across the country, which would otherwise be very good, is rendered impracticable for wagons by these streams. There is another trail among the mountains, usually followed in the summer, which the snows now compelled us to avoid; and I have reason to believe that this, passing nearer the heads of these streams, would afford a much better road.

At such places, the gun-carriage was unlimbered, and separately descended by hand. Continuing a few miles up the left bank of the river, we encamped early in an open bottom among the pines, a short distance below a lodge of Indians. Here, along the river the bluffs present escarpments seven or eight hundred feet in height, containing strata of a very fine porcelain clay, overlaid, at the height of about five hundred feet, by a massive stratum of compact basalt one hundred feet in thickness, which again is succeeded above by other strata of volcanic rocks. The clay strata are variously colored, some of them very nearly as white as chalk, and very fine-grained. Specimens brought from these have been subjected to microscopical examination by Professor Bailey, of West Point, and are considered by him to constitute one of the most remarkable deposites of fluviatile infusoria on record. While they abound in genera and species which are common in fresh water, but which rarely thrive where the water is even brackish, not one decidedly marine form is to be found among them; and their fresh-water origin is therefore beyond a doubt. It is equally certain that they lived and died at the situation where they were found, as they could scarcely have been transported by running waters without an admixture of sandy particles; from which, however, they are remarkably free. Fossil infusoria of a fresh-water origin had been previously detected by Mr. Bailey, in specimens brought by Mr. James D. Dana from the tertiary formation of Oregon. Most of the species in those specimens differed so much from those now living and known, that he was led to infer that they might belong to extinct species, and considered them also as affording proof of an alteration, in the formation from which they were obtained, of fresh and salt-water deposites, which, common enough in Europe, had not hitherto been noticed in the United States. Coming evidently from a locality entirely different, our specimens show very few species in common with those brought by Mr. Dana, but bear a much closer resemblance to those inhabiting the northeastern states. It is possible that they are from a more recent deposite; but the presence of a few remarkable forms which are common to the two localities renders it more probable that there is no great difference in their age.

I obtained here a good observation of an emersion of the second satellite; but clouds, which rapidly overspread the sky, prevented the usual number of observations. Those which we succeeded in obtaining, are, however, good; and give for the latitude of the place 44 deg. 35' 23", and for the longitude from the satellite 121 deg. 10' 25".



DECEMBER.

1st.—A short distance above our encampment, we crossed the river, which was thickly lined along its banks with ice. In common with all these mountain-streams the water was very clear and the current swift. It was not everywhere fordable, and the water was three or four feet deep at our crossing, and perhaps a hundred feet wide. As was frequently the case at such places, one of the mules got his pack, consisting of sugar, thoroughly wet, and turned into molasses. One of the guides informed me that this was a "salmon-water," and pointed out several ingeniously- contrived places to catch the fish; among the pines in the bottom I saw an immense one, about twelve feet in diameter. A steep ascent from the opposite bank delayed us again; and as, by the information of our guides, grass would soon become very scarce, we encamped on the height of land, in a marshy place among the pines, where there was an abundance of grass. We found here a single Nez Perce family, who had a very handsome horse in their drove, which we endeavored to obtain in exchange for a good cow; but the man "had two hearts," or, rather, he had one and his wife had another: she wanted the cow, but he loved the horse too much to part with it. These people attach great value to cattle, with which they are endeavoring to supply themselves.

2d.—In the first rays of the sun, the mountain peaks this morning presented a beautiful appearance, the snow being entirely covered with a hue of rosy gold. We traveled to-day over a very stony, elevated plain, about which were scattered cedar and pine, and encamped on another branch of Fall river. We were gradually ascending to a more elevated region, which would have been indicated by the rapidly increasing quantities of snow and ice, had we not known it by other means. A mule, which was packed with our cooking-utensils, wandered off among the pines unperceived, and several men were sent back to search for it.

3d.—Leaving Mr. Fitzpatrick with the party, I went ahead with the howitzer and a few men, in order to gain time, as our progress with the gun was necessarily slower. The country continued the same—very stony, with cedar and pine; and we rode on until dark, when we encamped on a hill-side covered with snow, which we used to-night for water, as we were unable to reach any stream.

4th.—Our animals had taken the back track, although a great number were hobbled; and we were consequently delayed until noon. Shortly after we had left this encampment, the mountain trail from the Dalles joined that on which we were traveling. After passing for several miles over an artemisia plain, the trail entered a beautiful pine forest, through which we traveled for several hours; and about 4 o'clock descended into the valley of another large branch, on the bottom of which were spaces of open pines, with occasional meadows of good grass, in one of which we encamped. The stream is very swift and deep, and about 40 feet wide, and nearly half frozen over. Among the timber here, are larches 140 feet high, and over three feet in diameter. We had to-night the rare sight of a lunar rainbow.

5th.—To-day the country was all pine forest, and beautiful weather made our journey delightful. It was too warm at noon for winter clothes; and the snow, which lay everywhere in patches through the forest, was melting rapidly. After a few hours' ride, we came upon a fine stream in the midst of the forest, which proved to be the principal branch of the Fall river. It was occasionally 200 feet wide—sometimes narrowed to 50 feet—the waters very clear, and frequently deep. We ascended along the river, which sometimes presented sheets of foaming cascades—its banks occasionally blackened with masses of scoriated rock—and found a good encampment on the verge of open bottom, which had been an old camping-ground of the Cayuse Indians. A great number of deer-horns were lying about, indicating game in the neighborhood. The timber was uniformly large, some of the pines measuring 22 feet in circumference at the ground, and 12 to 13 feet at six feet above.

In all our journeying, we had never traveled through a country where the rivers were so abounding in falls; and the name of this stream is singularly characteristic. At every place where we come in the neighborhood of the river, is heard the roaring of falls. The rock along the banks of the stream, and the ledge over which it falls, is a scoriated basalt, with a bright metallic fracture. The stream goes over in one clear pitch, succeeded by a foaming cataract of several hundred yards. In a little bottom above the falls, a small stream discharges into an entonnoir, and disappears below.

We made an early encampment, and in the course of the evening Mr. Fitzpatrick joined us here with the lost mule. Our lodge-poles were nearly worn out, and we found here a handsome set, leaning against one of the trees, very white, and cleanly scraped. Had the owners been here, we would have purchased them; but as they were not, we merely left the old ones in their place, with a small quantity of tobacco.

6th.—The morning was frosty and clear. We continued up the stream on undulating forest ground, over which there was scattered much falling timber. We met here a village of Nez Perce Indians, who appeared to be coming down from the mountains, and had with them fine bands of horses. With them were a few Snake Indians of the root-digging species. From the forest we emerged into an open valley ten or twelve miles wide, through which the stream was flowing tranquilly, upwards of two hundred feet broad, with occasional islands, and bordered with fine broad bottoms. Crossing the river, which here issues from a great mountain ridge on the right, we continued up the southern and smaller branch over a level country, consisting of fine meadow-land, alternating with pine forests, and encamped on it early in the evening. A warm sunshine made the day pleasant.

7th.—To-day we had good traveling ground, the trail leading sometimes over rather sandy soils in the pine forest, and sometimes over meadow-land along the stream. The great beauty of the country in summer constantly suggested itself to our imaginations; and even now we found it beautiful, as we rode along these meadows, from half a mile to two miles wide. The rich soil and excellent water, surrounded by noble forests, make a picture that would delight the eye of a farmer.

I observed to-night an occultation of a Geminorum; which, although at the bright limb of the moon, appears to give a very good result, that has been adopted for the longitude. The occultation, observations of satellites, and our position deduced from daily surveys with the compass, agree remarkably well together, and mutually support and strengthen each other. The latitude of the camp is 43 deg. 30' 36"; and longitude, deduced from the occultation, 121 deg. 33' 50".

8th.—To-day we crossed the last branch of the Fall river, issuing, like all the others we had crossed, in a southwesterly direction from the mountains. Our direction was a little east of south, the trail leading constantly through pine forests. The soil was generally bare, consisting, in greater part, of a yellowish-white pumice-stone, producing varieties of magnificent pines, but not a blade of grass; and to-night our horses were obliged to do without food, and use snow for water. These pines are remarkable for the red color of the bolls; and among them occurs a species of which the Indians had informed me when leaving the Dalles. The unusual size of the cone (16 or 18 inches long) had attracted their attention; and they pointed it out to me among the curiosities of the country. They are more remarkable for their large diameter than their height, which usually averages only about 120 feet. The leaflets are short—only two or three inches long, and five in a sheath; the bark of a red color.

9th.—The trail leads always through splendid pine forests. Crossing dividing grounds by a very fine road, we descended very gently towards the south. The weather was pleasant, and we halted late. The soil was very much like that of yesterday; and on the surface of a hill near our encampment, were displayed beds of pumice-stone; but the soil produced no grass, and again the animals fared badly.

10th.—The country began to improve; and about eleven o'clock we reached a spring of cold water on the edge of a savannah, or grassy meadow, which our guides informed us was an arm of the Tlamath lake; and a few miles further we entered upon an extensive meadow, or lake of grass, surrounded by timbered mountains. This was the Tlamath lake. It was a picturesque and beautiful spot, and rendered more attractive to us by the abundant and excellent grass, which our animals, after traveling through pine forests, so much needed; but the broad sheet of water which constitutes a lake was not to be seen. Overlooking it, immediately west, were several snowy knobs, belonging to what we have considered a branch of the Cascade range. A low point, covered with pines, made out into the lake, which afforded us a good place for an encampment, and for the security of our horses, which were guarded in view on the open meadow. The character of courage and hostility attributed to the Indians in this quarter induced more than usual precaution; and, seeing smokes rising from the middle of the lake (or savannah) and along the opposite shores, I directed the howitzer to be fired. It was the first time our guides had seen it discharged; and the bursting of the shell at a distance, which was something like the second fire of the gun, amazed and bewildered them with delight. It inspired them with triumphant feelings; but on the camps at a distance the effect was different, for the smokes in the lake and on the shores immediately disappeared.

The point on which we were encamped forms, with the opposite eastern shore, a narrow neck, connecting the body of the lake with a deep cove or bay which receives the principal affluent stream, and over the greater part of which the water (or rather ice) was at this time dispersed in shallow pools. Among the grass, and scattered over the prairie lake, appeared to be similar marshes. It is simply a shallow basin, which, for a short period at the time of melting snows, is covered with water from the neighboring mountains; but this probably soon runs off, and leaves for the remainder of the year a green savannah, through the midst of which the river Tlamath, which flows to the ocean, winds its way to the outlet on the south-western side.

11th.—No Indians made their appearance, and I determined to pay them a visit. Accordingly the people were gathered together, and we rode out towards the village in the middle of the lake which one of our guides had previously visited. It could not be directly approached, as a large part of the lake appeared a marsh; and there were sheets of ice among the grass on which our horses could not keep their footing. We therefore followed the guide for a considerable distance along the forest; and then turned off towards the village, which we soon began to see was a few large huts, on the tops of which were collected the Indians. When we had arrived within half a mile of the village, two persons were seen advancing to meet us; and, to please the fancy of our guides, we ranged ourselves into a long line, riding abreast, while they galloped ahead to meet the strangers.

We were surprised, on riding up, to find one of them a woman, having never before known a squaw to take any part in the business of war. They were the village chief and his wife, who, in excitement and alarm at the unusual event and appearance, had come out to meet their fate together. The chief was a very prepossessing Indian, with handsome features, and a singularly soft and agreeable voice—so remarkable as to attract general notice.

The huts were grouped together on the bank of the river which, from being spread out in a shallow marsh at the upper end of the lake, was collected here into a single stream. They were large round huts, perhaps 20 feet in diameter, with rounded tops, on which was the door by which they descended into the interior. Within, they were supported by posts and beams.

Almost like plants, these people seem to have adapted themselves to the soil, and to be growing on what the immediate locality afforded. Their only subsistence at the time appeared to be a small fish, great quantities of which, that had been smoked and dried, were suspended on strings about the lodge. Heaps of straw were lying around; and their residence in the midst of grass and rushes had taught them a peculiar skill in converting this material to useful purposes. Their shoes were made of straw or grass, which seemed well adapted for a snowy country; and the women wore on their heads a closely-woven basket, which made a very good cap. Among other things, were party-colored mats about four feet square, which we purchased to lay on the snow under our blankets, and to use for table-cloths.

Numbers of singular-looking dogs, resembling wolves, were sitting on the tops of the huts; and of these we purchased a young one, which, after its birthplace, was named Tlamath. The language spoken by these Indians is different from that of the Shoshonee and Columbia River tribes; and otherwise than by signs they cannot understand each other. They made us comprehend that they were at war with the people who lived to the southward and to the eastward; but I could obtain from them no certain information. The river on which they live enters the Cascade mountains on the western side of the lake, and breaks through them by a passage impracticable for travelers; but over the mountains, to the northward, are passes which present no other obstacle than in the almost impenetrable forests. Unlike any Indians we had previously seen, these wore shells in their noses. We returned to our camp, after remaining here an hour or two, accompanied by a number of Indians.

In order to recruit a little the strength of our animals, and obtain some acquaintance with the locality, we remained here for the remainder of the day. By observation, the latitude of the camp was 42 deg. 56' 51", and the diameter of the lake, or meadow, as has been intimated, about 20 miles. It is a picturesque and beautiful spot, and, under the hand of cultivation, might become a little paradise. Game is found in the forest, timbered and snowy mountains skirt it, and fertility characterizes it. Situated near the heads of three rivers, and on the line of inland communication with California, and near to Indians noted for treachery, it will naturally, in the progress of the settlement of Oregon, become a point for military occupation and settlement.

From Tlamath lake, the further continuation of our voyage assumed a character of discovery and exploration, which, from the Indians here, we could obtain no information to direct, and where the imaginary maps of the country, instead of assisting, exposed us to suffering and defeat. In our journey across the desert, Mary's lake, and the famous Buenaventura river, were two points on which I relied to recruit the animals and repose the party. Forming, agreeably to the best maps in my possession, a connected water-line from the Rocky mountains to the Pacific ocean, I felt no other anxiety than to pass safely across the intervening desert to the banks of the Buenaventura, where, in the softer climate of a more southern latitude, our horses might find grass to sustain them, and ourselves be sheltered from the rigors of winter, and from the inhospitable desert. The guides who had conducted us thus far on our journey were about to return; and I endeavored in vain to obtain others to lead us, even for a few days, in the direction (east) which we wished to go. The chief to whom I applied alleged the want of horses, and the snow on the mountains across which our course would carry us, and the sickness of his family, as reasons for refusing to go with us.

12th.—This morning the camp was thronged with Tlamath Indians from the southeastern shore of the lake; but, knowing the treacherous disposition which is a remarkable characteristic of the Indians south of the Columbia, the camp was kept constantly on its guard. I was not unmindful of the disasters which Smith and other travelers had met with in this country, and therefore was equally vigilant in guarding against treachery and violence.

According to the best information I had been able to obtain from the Indians, in a few days' traveling we should reach another large water, probably a lake, which they indicated exactly in the course we were about to pursue. We struck our tents at 10 o'clock, and crossed the lake in a nearly east direction, where it has the least extension—the breadth of the arm being here only about a mile and a half. There were ponds of ice, with but little grass, for the greater part of the way, and it was difficult to get the pack-animals across, which fell frequently, and could not get up with their loads, unassisted. The morning was very unpleasant, snow falling at intervals in large flakes, and the sky dark. In about two hours we succeeded in getting the animals over; and, after traveling another hour along the eastern shore of the lake, we turned up into a cove where there was a sheltered place among the timber, with good grass, and encamped. The Indians, who had accompanied us so far, returned to their village on the south-eastern shore. Among the pines here, I noticed some five or six feet in diameter.

13th.—The night has been cold; the peaks around the lake gleam out brightly in the morning sun, and the thermometer is at zero. We continued up the hollow formed by a small affluent to the lake, and immediately entered an open pine forest on the mountain. The way here was sometimes obstructed by fallen trees, and the snow was four to twelve inches deep. The mules at the gun pulled heavily, and walking was a little laborious. In the midst of the wood, we heard the sound of galloping horses, and were agreeably surprised by the unexpected arrival of our Tlamath chief with several Indians. He seemed to have found his conduct inhospitable in letting the strangers depart without a guide through the snow, and had come, with a few others, to pilot us a day or two on the way. After traveling in an easterly direction through the forest for about four hours, we reached a considerable stream, with a border of good grass; and here, by the advice of our guides, we encamped. It is about thirty feet wide, and two to four feet deep, the water clear, with some current; and, according to the information of our Indians, is the principal affluent to the lake, and the head-water of the Tlamath river.

A very clear sky enabled me to obtain here to-night good observations, including an emersion of the first satellite of Jupiter, which gave for the long. 121 deg. 20' 42", and for the lat. 42 deg. 51' 26". This emersion coincides remarkably well with the result obtained from an occultation at the encampment of December 7th to 8th, 1843; from which place, the line of our survey gives an easting of 13 miles. The day's journey was 12 miles.

14th.—Our road was over a broad mountain, and we rode seven hours in a thick snow-storm, always through pine forests, when we came down upon the head-waters of another stream, on which there was grass. The snow lay deep on the ground, and only the high swamp-grass appeared above. The Indians were thinly clad, and I had remarked during the day that they suffered from cold. This evening they told me that the snow was getting too deep on the mountain, and I could not induce them to go any farther. The stream we had struck issued from the mountain in an easterly direction, turning to the southward a short distance below; and, drawing its course upon the ground, they made us comprehend that it pursued its way for a long distance in that direction, uniting with many other streams, and gradually becoming a great river. Without the subsequent information, which confirmed the opinion, we became immediately satisfied that this water formed the principal stream of the Sacramento river; and, consequently, that this main affluent of the bay of San Francisco had its source within the limits of the United States, and opposite a tributary to the Columbia, and near the head of the Tlamath river, which goes to the ocean north of 42 deg., and within the United States.

15th.—A present, consisting of useful goods, afforded much satisfaction to our guides; and, showing them the national flag, I explained that it was a symbol of our nation; and they engaged always to receive it in a friendly manner. The chief pointed out a course, by following which we would arrive at the big water, where no more snow was to be found. Traveling in a direction N. 60 deg. E. by compass, which the Indians informed me would avoid a bad mountain to the right, we crossed the Sacramento where it turned to the southward, and entered a grassy level plain—a smaller Grand Rond; from the lower end of which the river issued into an inviting country of low rolling hills. Crossing a hard-frozen swamp on the farther side of the Rond, we entered again the pine forest, in which very deep snow made our traveling slow and laborious. We were slowly but gradually ascending a mountain; and, after a hard journey of seven hours, we came to some naked places among the timber, where a few tufts of grass showed above the snow, on the side of a hollow; and here we encamped. Our cow, which every day got poorer, was killed here, but the meat was rather tough.

16th.—We traveled this morning through snow about three feet deep, which, being crusted, very much cut the feet of our animals. The mountain still gradually rose; we crossed several spring heads covered with quaking asp; otherwise it was all pine forest. The air was dark with falling snow, which everywhere weighed down the trees. The depths of the forest were profoundly still; and below, we scarcely felt a breath of the wind which whirled the snow through their branches. I found that it required some exertion of constancy to adhere steadily to one course through the woods, when we were uncertain how far the forest extended, or what lay beyond; and, on account of our animals, it would be bad to spend another night on the mountain. Towards noon the forest looked clear ahead, appearing suddenly to terminate; and beyond a certain point we could see no trees. Riding rapidly ahead to this spot, we found ourselves on the verge of a vertical and rocky wall of the mountain. At our feet—more than a thousand feet below—we looked into a green prairie country, in which a beautiful lake, some twenty miles in length, was spread along the foot of the mountains, its shores bordered with green grass. Just then the sun broke out among the clouds, and illuminated the country below; while around us the storm raged fiercely. Not a particle of ice was to be seen on the lake, or snow on its borders, and all was like summer or spring. The glow of the sun in the valley below brightened up our hearts with sudden pleasure; and we made the woods ring with joyful shouts to those behind; and gradually, as each came up, he stopped to enjoy the unexpected scene. Shivering on snow three feet deep, and stiffening in a cold north wind, we exclaimed at once that the names of Summer Lake and Winter Ridge should be applied to these two proximate places of such sudden and violent contrast.
