We hoped to finish the two canoes in three days. A space was cleared in the forest for our tents. Among the taller trees grew huge-leafed pacovas, or wild bananas. We bathed and swam in the river, although in it we caught piranhas. Carregadores ants swarmed all around our camp. As many of the nearest of their holes as we could we stopped with fire; but at night some of them got into our tents and ate things we could ill spare. In the early morning a column of foraging ants appeared, and we drove them back, also with fire. When the sky was not overcast the sun was very hot, and we spread out everything to dry. There were many wonderful butterflies round about, but only a few birds. Yet in the early morning and late afternoon there was some attractive bird music in the woods. The two best performers were our old friend the false bellbird, with its series of ringing whistles, and a shy, attractive ant-thrush. The latter walked much on the ground, with dainty movements, curtseying and raising its tail; and in accent and sequence, although not in tone or time, its song resembled that of our white-throated sparrow.

It was three weeks since we had started down the River of Doubt. We had come along its winding course about 140 kilometres, with a descent of somewhere in the neighborhood of 124 metres. It had been slow progress. We could not tell what physical obstacles were ahead of us, nor whether the Indians would be actively hostile. But a river normally describes in its course a parabola, the steep descent being in the upper part; and we hoped that in the future we should not have to encounter so many and such difficult rapids as we had already encountered, and that therefore we would make better time—a hope destined to failure.



IX. DOWN AN UNKNOWN RIVER INTO THE EQUATORIAL FOREST

The mightiest river in the world is the Amazon. It runs from west to east, from the sunset to the sunrise, from the Andes to the Atlantic. The main stream flows almost along the equator, while the basin which contains its affluents extends many degrees north and south of the equator. The gigantic equatorial river basin is filled with an immense forest, the largest in the world, with which no other forest can be compared save those of western Africa and Malaysia. We were within the southern boundary of this great equatorial forest, on a river which was not merely unknown but unguessed at, no geographer having ever suspected its existence. This river flowed northward toward the equator, but whither it would go, whether it would turn one way or another, the length of its course, where it would come out, the character of the stream itself, and the character of the dwellers along its banks—all these things were yet to be discovered.

One morning while the canoes were being built Kermit and I walked a few kilometres down the river and surveyed the next rapids below. The vast still forest was almost empty of life. We found old Indian signs. There were very few birds, and these in the tops of the tall trees. We saw a recent tapir track; and under a cajazeira tree by the bank there were the tracks of capybaras which had been eating the fallen fruit. This fruit is delicious and would make a valuable addition to our orchards. The tree although tropical is hardy, thrives when domesticated, and propagates rapidly from shoots. The Department of Agriculture should try whether it would not grow in southern California and Florida. This was the tree from which the doctor's family name was taken. His parental grandfather, although of Portuguese blood, was an intensely patriotic Brazilian. He was a very young man when the independence of Brazil was declared, and did not wish to keep the Portuguese family name; so he changed it to that of the fine Brazilian tree in question. Such change of family names is common in Brazil. Doctor Vital Brazil, the student of poisonous serpents, was given his name by his father, whose own family name was entirely different; and his brother's name was again different.

There were tremendous downpours of rain, lasting for a couple of hours and accompanied by thunder and lightning. But on the whole it seemed as if the rains were less heavy and continuous than they had been. We all of us had to help in building the canoes now and then. Kermit, accompanied by Antonio the Parecis and Joao, crossed the river and walked back to the little river that had entered from the east, so as to bring back a report of it to Colonel Rondon. Lyra took observations, by the sun and by the stars. We were in about latitude 11 degrees 2 minutes south, and due north of where we had started. The river had wound so that we had gone two miles for every one we made northward. Our progress had been very slow; and until we got out of the region of incessant rapids, with their attendant labor and hazard, it was not likely that we should go much faster.

On the morning of March 22 we started in our six canoes. We made ten kilometres. Twenty minutes after starting we came to the first rapids. Here every one walked except the three best paddlers, who took the canoes down in succession—an hour's job. Soon after this we struck a bees' nest in the top of a tree overhanging the river; our steersman climbed out and robbed it, but, alas! lost the honey on the way back. We came to a small steep fall which we did not dare run in our over- laden, clumsy, and cranky dugouts. Fortunately, we were able to follow a deep canal which led off for a kilometre, returning just below the falls, fifty yards from where it had started. Then, having been in the boats and in motion only one hour and a half, we came to a long stretch of rapids which it took us six hours to descend, and we camped at the foot. Everything was taken out of the canoes, and they were run down in succession. At one difficult and perilous place they were let down by ropes; and even thus we almost lost one.

We went down the right bank. On the opposite bank was an Indian village, evidently inhabited only during the dry season. The marks on the stumps of trees showed that these Indians had axes and knives; and there were old fields in which maize, beans, and cotton had been grown. The forest dripped and steamed. Rubber-trees were plentiful. At one point the tops of a group of tall trees were covered with yellow- white blossoms. Others bore red blossoms. Many of the big trees, of different kinds, were buttressed at the base with great thin walls of wood. Others, including both palms and ordinary trees, showed an even stranger peculiarity. The trunk, near the base, but sometimes six or eight feet from the ground, was split into a dozen or twenty branches or small trunks which sloped outward in tent-like shape, each becoming a root. The larger trees of this type looked as if their trunks were seated on the tops of the pole frames of Indian tepees. At one point in the stream, to our great surprise, we saw a flying fish. It skimmed the water like a swallow for over twenty yards.

Although we made only ten kilometres we worked hard all day. The last canoes were brought down and moored to the bank at nightfall. Our tents were pitched in the darkness.

Next day we made thirteen kilometres. We ran, all told, a little over an hour and three-quarters. Seven hours were spent in getting past a series of rapids at which the portage, over rocky and difficult ground, was a kilometre long. The canoes were run down empty—a hazardous run, in which one of them upset.

Yet while we were actually on the river, paddling and floating downstream along the reaches of swift, smooth water, it was very lovely. When we started in the morning the day was overcast and the air was heavy with vapor. Ahead of us the shrouded river stretched between dim walls of forest, half seen in the mist. Then the sun burned up the fog, and loomed through it in a red splendor that changed first to gold and then to molten white. In the dazzling light, under the brilliant blue of the sky, every detail of the magnificent forest was vivid to the eye: the great trees, the network of bush ropes, the caverns of greenery, where thick-leaved vines covered all things else. Wherever there was a hidden boulder the surface of the current was broken by waves. In one place, in midstream, a pyramidal rock thrust itself six feet above the surface of the river. On the banks we found fresh Indian sign.

At home in Vermont Cherrie is a farmer, with a farm of six hundred acres, most of it woodland. As we sat at the foot of the rapids, watching for the last dugouts with their naked paddlers to swing into sight round the bend through the white water, we talked of the northern spring that was just beginning. He sells cream, eggs, poultry, potatoes, honey, occasionally pork and veal; but at this season it was the time for the maple sugar crop. He has a sugar orchard, where he taps twelve hundred trees and hopes soon to tap as many more in addition. Said Cherrie: "It's a busy time now for Fred Rice"—Fred Rice is the hired man, and in sugar time the Cherrie boys help him with enthusiasm, and, moreover, are paid with exact justice for the work they do. There is much wild life about the farm, although it is near Brattleboro. One night in early spring a bear left his tracks near the sugar house; and now and then in summer Cherrie has had to sleep in the garden to keep the deer away from the beans, cabbages, and beets.

There was not much bird life in the forest, but Cherrie kept getting species new to the collection. At this camp he shot an interesting little ant-thrush. It was the size of a warbler, jet-black, with white under-surfaces of the wings and tail, white on the tail-feathers, and a large spot of white on the back, normally almost concealed, the feathers on the back being long and fluffy. When he shot the bird, a male, it was showing off before a dull-colored little bird, doubtless the female; and the chief feature of the display was this white spot on the back. The white feathers were raised and displayed so that the spot flashed like the "chrysanthemum" on a prongbuck whose curiosity has been aroused. In the gloom of the forest the bird was hard to see, but the flashing of this patch of white feathers revealed it at once, attracting immediate attention. It was an excellent example of a coloration mark which served a purely advertising purpose; apparently it was part of a courtship display. The bird was about thirty feet up in the branches.

In the morning, just before leaving this camp, a tapir swam across stream a little way above us; but unfortunately we could not get a shot at it. An ample supply of tapir beef would have meant much to us. We had started with fifty days' rations; but this by no means meant full rations, in the sense of giving every man all he wanted to eat. We had two meals a day, and were on rather short commons—both our mess and the camaradas'—except when we got plenty of palm-tops. For our mess we had the boxes chosen by Fiala, each containing a day's rations for six men, our number. But we made each box last a day and a half, or at times two days, and in addition we gave some of the food to the camaradas. It was only on the rare occasions when we had killed some monkeys or curassows, or caught some fish, that everybody had enough. We would have welcomed that tapir. So far the game, fish, and fruit had been too scarce to be an element of weight in our food supply. In an exploring trip like ours, through a difficult and utterly unknown country, especially if densely forested, there is little time to halt, and game cannot be counted on. It is only in lands like our own West thirty years ago, like South Africa in the middle of the last century, like East Africa to-day that game can be made the chief food supply. On this trip our only substantial food supply from the country hitherto had been that furnished by the palmtops. Two men were detailed every day to cut down palms for food.

A kilometre and a half after leaving this camp we came on a stretch of big rapids. The river here twists in loops, and we had heard the roaring of these rapids the previous afternoon. Then we passed out of earshot of them; but Antonio Correa, our best waterman, insisted all along that the roaring meant rapids worse than any we had encountered for some days. "I was brought up in the water, and I know it like a fish, and all its sounds," said he. He was right. We had to carry the loads nearly a kilometre that afternoon, and the canoes were pulled out on the bank so that they might be in readiness to be dragged overland next day. Rondon, Lyra, Kermit, and Antonio Correa explored both sides of the river. On the opposite or left bank they found the mouth of a considerable river, bigger than the Rio Kermit, flowing in from the west and making its entrance in the middle of the rapids. This river we christened the Taunay, in honor of a distinguished Brazilian, an explorer, a soldier, a senator, who was also a writer of note. Kermit had with him two of his novels, and I had read one of his books dealing with a disastrous retreat during the Paraguayan war.

Next morning, the 25th, the canoes were brought down. A path was chopped for them and rollers laid; and half-way down the rapids Lyra and Kermit, who were overseeing the work as well as doing their share of the pushing and hauling, got them into a canal of smooth water, which saved much severe labor. As our food supply lowered we were constantly more desirous of economizing the strength of the men. One day more would complete a month since we had embarked on the Duvida as we had started in February, the lunar and calendar months coincided. We had used up over half our provisions. We had come only a trifle over 160 kilometres, thanks to the character and number of the rapids. We believed we had three or four times the distance yet to go before coming to a part of the river where we might hope to meet assistance, either from rubber-gatherers, or from Pyrineus, if he were really coming up the river which we were going down. If the rapids continued to be as they had been it could not be much more than three weeks before we were in straits for food, aside from the ever-present danger of accident in the rapids; and if our progress were no faster than it had been—and we were straining to do our best—we would in such event still have several hundreds of kilometres of unknown river before us. We could not even hazard a guess at what was in front. The river was now a really big river, and it seemed impossible that it could flow either into the Gy-Parana or the Tapajos. It was possible that it went into the Canuma, a big affluent of the Madeira low down, and next to the Tapajos. It was more probable that it was the headwaters of the Aripuanan, a river which, as I have said, was not even named on the excellent English map of Brazil I carried. Nothing but the mouth had been known to any geographer; but the lower course had long been known to rubber-gatherers, and recently a commission from the government of Amazonas had partway ascended one branch of it—not as far as the rubber-gatherers had gone, and, as it turned out, not the branch we came down.

Two of our men were down with fever. Another man, Julio, a fellow of powerful frame, was utterly worthless, being an inborn, lazy shirk with the heart of a ferocious cur in the body of a bullock. The others were good men, some of them very good indeed. They were under the immediate supervision of Pedrinho Craveiro, who was first-class in every way.

This camp was very lovely. It was on the edge of a bay, into which the river broadened immediately below the rapids. There was a beach of white sand, where we bathed and washed our clothes. All around us, and across the bay, and on both sides of the long water-street made by the river, rose the splendid forest. There were flocks of parakeets colored green, blue, and red. Big toucans called overhead, lustrous green-black in color, with white throats, red gorgets, red-and-yellow tail coverts, and huge black-and-yellow bills. Here the soil was fertile; it will be a fine site for a coffee-plantation when this region is open to settlement. Surely such a rich and fertile land cannot be permitted to remain idle, to lie as a tenantless wilderness, while there are such teeming swarms of human beings in the overcrowded, over-peopled countries of the Old World. The very rapids and waterfalls which now make the navigation of the river so difficult and dangerous would drive electric trolleys up and down its whole length and far out on either side, and run mills and factories, and lighten the labor on farms. With the incoming of settlement and with the steady growth of knowledge how to fight and control tropical diseases, fear of danger to health would vanish. A land like this is a hard land for the first explorers, and perhaps for their immediate followers, but not for the people who come after them.

In mid-afternoon we were once more in the canoes; but we had paddled with the current only a few minutes, we had gone only a kilometre, when the roar of rapids in front again forced us to haul up to the bank. As usual, Rondon, Lyra, and Kermit, with Antonio Correa, explored both sides while camp was being pitched. The rapids were longer and of steeper descent than the last, but on the opposite or western side there was a passage down which we thought we could get the empty dugouts at the cost of dragging them only a few yards at one spot. The loads were to be carried down the hither bank, for a kilometre, to the smooth water. The river foamed between great rounded masses of rock, and at one point there was a sheer fall of six or eight feet. We found and ate wild pineapples. Wild beans were in flower. At dinner we had a toucan and a couple of parrots, which were very good.

All next day was spent by Lyra in superintending our three best watermen as they took the canoes down the west side of the rapids, to the foot, at the spot to which the camp had meantime been shifted. In the forest some of the huge sipas, or rope vines, which were as big as cables, bore clusters of fragrant flowers. The men found several honey-trees, and fruits of various kinds, and small cocoanuts; they chopped down an ample number of palms, for the palm-cabbage; and, most important of all, they gathered a quantity of big Brazil-nuts, which when roasted tasted like the best of chestnuts and are nutritious; and they caught a number of big piranhas, which were good eating. So we all had a feast, and everybody had enough to eat and was happy.

By these rapids, at the fall, Cherrie found some strange carvings on a bare mass of rock. They were evidently made by men a long time ago. As far as is known, the Indians thereabouts make no such figures now. They were in two groups, one on the surface of the rock facing the land, the other on that facing the water. The latter were nearly obliterated. The former were in good preservation, the figures sharply cut into the rock. They consisted, upon the upper flat part of the rock, of four multiple circles with a dot in the middle (O), very accurately made and about a foot and a half in diameter; and below them, on the side of the rock, four multiple m's or inverted w's (M). What these curious symbols represented, or who made them, we could not, of course, form the slightest idea. It may be that in a very remote past some Indian tribes of comparatively advanced culture had penetrated to this lovely river, just as we had now come to it. Before white men came to South America there had already existed therein various semi-civilizations, some rude, others fairly advanced, which rose, flourished, and persisted through immemorial ages, and then vanished. The vicissitudes in the history of humanity during its stay on this southern continent have been as strange, varied, and inexplicable as paleontology shows to have been the case, on the same continent, in the history of the higher forms of animal life during the age of mammals. Colonel Rondon stated that such figures as these are not found anywhere else in Matto Grosso where he has been, and therefore it was all the more strange to find them in this one place on the unknown river, never before visited by white men, which we were descending.

Next morning we went about three kilometers before coming to some steep hills, beautiful to look upon, clad as they were in dense, tall, tropical forest, but ominous of new rapids. Sure enough, at their foot we had to haul up and prepare for a long portage. The canoes we ran down empty. Even so, we were within an ace of losing two, the lashed couple in which I ordinarily journeyed. In a sharp bend of the rapids, between two big curls, they were swept among the boulders and under the matted branches which stretched out from the bank. They filled, and the racing current pinned them where they were, one partly on the other. All of us had to help get them clear. Their fastenings were chopped asunder with axes. Kermit and half a dozen of the men, stripped to the skin, made their way to a small rock island in the little falls just above the canoes, and let down a rope which we tied to the outermost canoe. The rest of us, up to our armpits and barely able to keep our footing as we slipped and stumbled among the boulders in the swift current, lifted and shoved while Kermit and his men pulled the rope and fastened the slack to a half-submerged tree. Each canoe in succession was hauled up the little rock island, baled, and then taken down in safety by two paddlers. It was nearly four o'clock before we were again ready to start, having been delayed by a rain- storm so heavy that we could not see across the river. Ten minutes' run took us to the head of another series of rapids; the exploring party returned with the news that we had an all day's job ahead of us; and we made camp in the rain, which did not matter much, as we were already drenched through. It was impossible, with the wet wood, to make a fire sufficiently hot to dry all our soggy things, for the rain was still falling. A tapir was seen from our boat, but, as at the moment we were being whisked round in a complete circle by a whirlpool, I did not myself see it in time to shoot.

Next morning we went down a kilometre, and then landed on the other side of the river. The canoes were run down, and the loads carried to the other side of a little river coming in from the west, which Colonel Rondon christened Cherrie River. Across this we went on a bridge consisting of a huge tree felled by Macario, one of our best men. Here we camped, while Rondon, Lyra, Kermit, and Antonio Correa explored what was ahead. They were absent until mid-afternoon. Then they returned with the news that we were among ranges of low mountains, utterly different in formation from the high plateau region to which the first rapids, those we had come to on the 2nd of March, belonged. Through the first range of these mountains the river ran in a gorge, some three kilometres long, immediately ahead of us. The ground was so rough and steep that it would be impossible to drag the canoes over it and difficult enough to carry the loads; and the rapids were so bad, containing several falls, one of at least ten metres in height, that it was doubtful how many of the canoes we could get down them. Kermit, who was the only man with much experience of rope work, was the only man who believed we could get the canoes down at all; and it was, of course, possible that we should have to build new ones at the foot to supply the place of any that were lost or left behind. In view of the length and character of the portage, and of all the unpleasant possibilities that were ahead, and of the need of keeping every pound of food, it was necessary to reduce weight in every possible way and to throw away everything except the barest necessities.

We thought we had reduced our baggage before; but now we cut to the bone. We kept the fly for all six of us to sleep under. Kermit's shoes had gone, thanks to the amount of work in the water which he had been doing; and he took the pair I had been wearing, while I put on my spare pair. In addition to the clothes I wore, I kept one set of pajamas, a spare pair of drawers, a spare pair of socks, half a dozen handkerchiefs, my wash-kit, my pocket medicine-case, and a little bag containing my spare spectacles, gun-grease, some adhesive plaster, some needles and thread, the "fly-dope," and my purse and letter of credit, to be used at Manaos. All of these went into the bag containing my cot, blanket, and mosquito-net. I also carried a cartridge-bag containing my cartridges, head-net, and gauntlets. Kermit cut down even closer; and the others about as close.

The last three days of March we spent in getting to the foot of the rapids in this gorge. Lyra and Kermit, with four of the best watermen, handled the empty canoes. The work was not only difficult and laborious in the extreme, but hazardous; for the walls of the gorge were so sheer that at the worst places they had to cling to narrow shelves on the face of the rock, while letting the canoes down with ropes. Meanwhile Rondon surveyed and cut a trail for the burden- bearers, and superintended the portage of the loads. The rocky sides of the gorge were too steep for laden men to attempt to traverse them. Accordingly the trail had to go over the top of the mountain, both the ascent and the descent of the rock-strewn, forest-clad slopes being very steep. It was hard work to carry loads over such a trail. From the top of the mountain, through an opening in the trees on the edge of a cliff, there was a beautiful view of the country ahead. All around and in front of us there were ranges of low mountains about the height of the lower ridges of the Alleghenies. Their sides were steep and they were covered with the matted growth of the tropical forest. Our next camping-place, at the foot of the gorge, was almost beneath us, and from thence the river ran in a straight line, flecked with white water, for about a kilometre. Then it disappeared behind and between mountain ridges, which we supposed meant further rapids. It was a view well worth seeing; but, beautiful although the country ahead of us was, its character was such as to promise further hardships, difficulty, and exhausting labor, and especially further delay; and delay was a serious matter to men whose food supply was beginning to run short, whose equipment was reduced to the minimum, who for a month, with the utmost toil, had made very slow progress, and who had no idea of either the distance or the difficulties of the route in front of them.

There was not much life in the woods, big or little. Small birds were rare, although Cherrie's unwearied efforts were rewarded from time to time by a species new to the collection. There were tracks of tapir, deer, and agouti; and if we had taken two or three days to devote to nothing else than hunting them we might perchance have killed something; but the chance was much too uncertain, the work we were doing was too hard and wearing, and the need of pressing forward altogether too great to permit us to spend any time in such manner. The hunting had to come in incidentally. This type of well nigh impenetrable forest is the one in which it is most difficult to get even what little game exists therein. A couple of curassows and a big monkey were killed by the colonel and Kermit. On the day the monkey was brought in Lyra, Kermit, and their four associates had spent from sunrise to sunset in severe and at moments dangerous toil among the rocks and in the swift water, and the fresh meat was appreciated. The head, feet, tail, skin, and entrails were boiled for the gaunt and ravenous dogs. The flesh gave each of us a few mouthfuls; and how good those mouthfuls tasted!

Cherrie, in addition to being out after birds in every spare moment, helped in all emergencies. He was a veteran in the work of the tropic wilderness. We talked together often, and of many things, for our views of life, and of a man's duty to his wife and children, to other men, and to women, and to the state in peace and war, were in all essentials the same. His father had served all through the Civil War, entering an Iowa cavalry regiment as a private and coming out as a captain; his breast-bone was shattered by a blow from a musket-butt, in hand-to-hand fighting at Shiloh.

During this portage the weather favored us. We were coming toward the close of the rainy season. On the last day of the month, when we moved camp to the foot of the gorge, there was a thunder-storm; but on the whole we were not bothered by rain until the last night, when it rained heavily, driving under the fly so as to wet my cot and bedding. However, I slept comfortably enough, rolled in the damp blanket. Without the blanket I should have been uncomfortable; a blanket is a necessity for health. On the third day Lyra and Kermit, with their daring and hard-working watermen, after wearing labor, succeeded in getting five canoes through the worst of the rapids to the chief fall. The sixth, which was frail and weak, had its bottom beaten out on the jagged rocks of the broken water. On this night, although I thought I had put my clothes out of reach, both the termites and the carregadores ants got at them, ate holes in one boot, ate one leg of my drawers, and riddled my handkerchief; and I now had nothing to replace anything that was destroyed.

Next day Lyra, Kermit, and their camaradas brought the five canoes that were left down to camp. They had in four days accomplished a work of incredible labor and of the utmost importance; for at the first glance it had seemed an absolute impossibility to avoid abandoning the canoes when we found that the river sank into a cataract broken torrent at the bottom of a canyon-like gorge between steep mountains. On April 2 we once more started, wondering how soon we should strike other rapids in the mountains ahead, and whether in any reasonable time we should, as the aneroid indicated, be so low down that we should necessarily be in a plain where we could make a journey of at least a few days without rapids. We had been exactly a month going through an uninterrupted succession of rapids. During that month we had come only about 110 kilometres, and had descended nearly 150 metres—the figures are approximate but fairly accurate. We had lost four of the canoes with which we started, and one other, which we had built, and the life of one man; and the life of a dog which by its death had in all probability saved the life of Colonel Rondon. In a straight line northward, toward our supposed destination, we had not made more than a mile and a quarter a day; at the cost of bitter toil for most of the party, of much risk for some of the party, and of some risk and some hardship for all the party. Most of the camaradas were downhearted, naturally enough, and occasionally asked one of us if we really believed that we should ever get out alive; and we had to cheer them up as best we could.

There was no change in our work for the time being. We made but three kilometres that day. Most of the party walked all the time; but the dugouts carried the luggage until we struck the head of the series of rapids which were to take up the next two or three days. The river rushed through a wild gorge, a chasm or canyon, between two mountains. Its sides were very steep, mere rock walls, although in most places so covered with the luxuriant growth of the trees and bushes that clung in the crevices, and with green moss, that the naked rock was hardly seen. Rondon, Lyra, and Kermit, who were in front, found a small level spot, with a beach of sand, and sent back word to camp there, while they spent several hours in exploring the country ahead. The canoes were run down empty, and the loads carried painfully along the face of the cliffs; so bad was the trail that I found it rather hard to follow, although carrying nothing but my rifle and cartridge bag. The explorers returned with the information that the mountains stretched ahead of us, and that there were rapids as far as they had gone. We could only hope that the aneroid was not hopelessly out of kilter, and that we should, therefore, fairly soon find ourselves in comparatively level country. The severe toil, on a rather limited food supply, was telling on the strength as well as on the spirits of the men; Lyra and Kermit, in addition to their other work, performed as much actual physical labor as any of them.

Next day, the 3rd of April, we began the descent of these sinister rapids of the chasm. Colonel Rondon had gone to the summit of the mountain in order to find a better trail for the burden-bearers, but it was hopeless, and they had to go along the face of the cliffs. Such an exploring expedition as that in which we were engaged of necessity involves hard and dangerous labor, and perils of many kinds. To follow down-stream an unknown river, broken by innumerable cataracts and rapids, rushing through mountains of which the existence has never been even guessed, bears no resemblance whatever to following even a fairly dangerous river which has been thoroughly explored and has become in some sort a highway, so that experienced pilots can be secured as guides, while the portages have been pioneered and trails chopped out, and every dangerous feature of the rapids is known beforehand. In this case no one could foretell that the river would cleave its way through steep mountain chains, cutting narrow clefts in which the cliff walls rose almost sheer on either hand. When a rushing river thus "canyons," as we used to say out West, and the mountains are very steep, it becomes almost impossible to bring the canoes down the river itself and utterly impossible to portage them along the cliff sides, while even to bring the loads over the mountain is a task of extraordinary labor and difficulty. Moreover, no one can tell how many times the task will have to be repeated, or when it will end, or whether the food will hold out; every hour of work in the rapids is fraught with the possibility of the gravest disaster, and yet it is imperatively necessary to attempt it; and all this is done in an uninhabited wilderness, or else a wilderness tenanted only by unfriendly savages, where failure to get through means death by disease and starvation. Wholesale disasters to South American exploring parties have been frequent. The first recent effort to descend one of the unknown rivers to the Amazon from the Brazilian highlands resulted in such a disaster. It was undertaken in 1889 by a party about as large as ours under a Brazilian engineer officer, Colonel Telles Peres. In descending some rapids they lost everything— canoes, food, medicine, implements—everything. Fever smote them, and then starvation. All of them died except one officer and two men, who were rescued months later. Recently, in Guiana, a wilderness veteran, Andre, lost two-thirds of his party by starvation. Genuine wilderness exploration is as dangerous as warfare. The conquest of wild nature demands the utmost vigor, hardihood, and daring, and takes from the conquerors a heavy toll of life and health.

Lyra, Kermit, and Cherrie, with four of the men, worked the canoes half-way down the canyon. Again and again it was touch and go whether they could get by a given point. At one spot the channel of the furious torrent was only fifteen yards across. One canoe was lost, so that of the seven with which we had started only two were left. Cherrie labored with the other men at times, and also stood as guard over them, for, while actually working, of course no one could carry a rifle. Kermit's experience in bridge building was invaluable in enabling him to do the rope work by which alone it was possible to get the canoes down the canyon. He and Lyra had now been in the water for days. Their clothes were never dry. Their shoes were rotten. The bruises on their feet and legs had become sores. On their bodies some of the insect bites had become festering wounds, as indeed was the case with all of us. Poisonous ants, biting flies, ticks, wasps, bees were a perpetual torment. However, no one had yet been bitten by a venomous serpent, a scorpion, or a centipede, although we had killed all of the three within camp limits.

Under such conditions whatever is evil in men's natures comes to the front. On this day a strange and terrible tragedy occurred. One of the camaradas, a man of pure European blood, was the man named Julio, of whom I have already spoken. He was a very powerful fellow and had been importunately eager to come on the expedition; and he had the reputation of being a good worker. But, like so many men of higher standing, he had had no idea of what such an expedition really meant, and under the strain of toil, hardship, and danger his nature showed its true depths of selfishness, cowardice, and ferocity. He shirked all work. He shammed sickness. Nothing could make him do his share; and yet unlike his self-respecting fellows he was always shamelessly begging for favors. Kermit was the only one of our party who smoked; and he was continually giving a little tobacco to some of the camaradas, who worked especially well under him. The good men did not ask for it; but Julio, who shirked every labor, was always, and always in vain, demanding it. Colonel Rondon, Lyra, and Kermit each tried to get work out of him, and in order to do anything with him had to threaten to leave him in the wilderness. He threw all his tasks on his comrades; and, moreover, he stole their food as well as ours. On such an expedition the theft of food comes next to murder as a crime, and should by rights be punished as such. We could not trust him to cut down palms or gather nuts, because he would stay out and eat what ought to have gone into the common store. Finally, the men on several occasions themselves detected him stealing their food. Alone of the whole party, and thanks to the stolen food, he had kept in full flesh and bodily vigor.

One of our best men was a huge negro named Paixao Paishon—a corporal and acting sergeant in the engineer corps. He had, by the way, literally torn his trousers to pieces, so that he wore only the tatters of a pair of old drawers until I gave him my spare trousers when we lightened loads. He was a stern disciplinarian. One evening he detected Julio stealing food and smashed him in the mouth. Julio came crying to us, his face working with fear and malignant hatred; but after investigation he was told that he had gotten off uncommonly lightly. The men had three or four carbines, which were sometimes carried by those who were not their owners.

On this morning, at the outset of the portage, Pedrinho discovered Julio stealing some of the men's dried meat. Shortly afterward Paishon rebuked him for, as usual, lagging behind. By this time we had reached the place where the canoes were tied to the bank and then taken down one at a time. We were sitting down, waiting for the last loads to be brought along the trail. Pedrinho was still in the camp we had left. Paishon had just brought in a load, left it on the ground with his carbine beside it, and returned on the trail for another load. Julio came in, put down his load, picked up the carbine, and walked back on the trail, muttering to himself but showing no excitement. We thought nothing of it, for he was always muttering; and occasionally one of the men saw a monkey or big bird and tried to shoot it, so it was never surprising to see a man with a carbine.

In a minute we heard a shot; and in a short time three or four of the men came up the trail to tell us that Paishon was dead, having been shot by Julio, who had fled into the woods. Colonel Rondon and Lyra were ahead; I sent a messenger for them, directed Cherrie and Kermit to stay where they were and guard the canoes and provisions, and started down the trail with the doctor—an absolutely cool and plucky man, with a revolver but no rifle—and a couple of the camaradas. We soon passed the dead body of poor Paishon. He lay in a huddle, in a pool of his own blood, where he had fallen, shot through the heart. I feared that Julio had run amuck, and intended merely to take more lives before he died, and that he would begin with Pedrinho, who was alone and unarmed in the camp we had left. Accordingly I pushed on, followed by my companions, looking sharply right and left; but when we came to the camp the doctor quietly walked by me, remarking, "My eyes are better than yours, colonel; if he is in sight I'll point him out to you, as you have the rifle." However, he was not there, and the others soon joined us with the welcome news that they had found the carbine.

The murderer had stood to one side of the path and killed his victim, when a dozen paces off, with deliberate and malignant purpose. Then evidently his murderous hatred had at once given way to his innate cowardice; and, perhaps hearing some one coming along the path, he fled in panic terror into the wilderness. A tree had knocked the carbine from his hand. His footsteps showed that after going some rods he had started to return, doubtless for the carbine, but had fled again, probably because the body had then been discovered. It was questionable whether or not he would live to reach the Indian villages, which were probably his goal. He was not a man to feel remorse—never a common feeling; but surely that murderer was in a living hell, as, with fever and famine leering at him from the shadows, he made his way through the empty desolation of the wilderness. Franca, the cook, quoted out of the melancholy proverbial philosophy of the people the proverb: "No man knows the heart of any one"; and then expressed with deep conviction a weird ghostly belief I had never encountered before: "Paishon is following Julio now, and will follow him until he dies; Paishon fell forward on his hands and knees, and when a murdered man falls like that his ghost will follow the slayer as long as the slayer lives."

We did not attempt to pursue the murderer. We could not legally put him to death, although he was a soldier who in cold blood had just deliberately killed a fellow soldier. If we had been near civilization we would have done our best to bring him in and turn him over to justice. But we were in the wilderness, and how many weeks' journey were ahead of us we could not tell. Our food was running low, sickness was beginning to appear among the men, and both their courage and their strength were gradually ebbing. Our first duty was to save the lives and the health of the men of the expedition who had honestly been performing, and had still to perform, so much perilous labor. If we brought the murderer in he would have to be guarded night and day on an expedition where there were always loaded firearms about, and where there would continually be opportunity and temptation for him to make an effort to seize food and a weapon and escape, perhaps murdering some other good man. He could not be shackled while climbing along the cliff slopes; he could not be shackled in the canoes, where there was always chance of upset and drowning; and standing guard would be an additional and severe penalty on the weary, honest men already exhausted by overwork. The expedition was in peril, and it was wise to take every chance possible that would help secure success. Whether the murderer lived or died in the wilderness was of no moment compared with the duty of doing everything to secure the safety of the rest of the party. For the two days following we were always on the watch against his return, for he could have readily killed some one else by rolling rocks down on any of the men working on the cliff sides or in the bottom of the gorge. But we did not see him until the morning of the third day. We had passed the last of the rapids of the chasm, and the four boats were going down-stream when he appeared behind some trees on the bank and called out that he wished to surrender and be taken aboard; for the murderer was an arrant craven at heart, a strange mixture of ferocity and cowardice. Colonel Rondon's boat was far in advance; he did not stop nor answer. I kept on in similar fashion with the rear boats, for I had no intention of taking the murderer aboard, to the jeopardy of the other members of the party, unless Colonel Rondon told me that it would have to be done in pursuance of his duty as an officer of the army and a servant of the Government of Brazil. At the first halt Colonel Rondon came up to me and told me that this was his view of his duty, but that he had not stopped because he wished first to consult me as the chief of the expedition. I answered that for the reasons enumerated above I did not believe that in justice to the good men of the expedition we should jeopardize their safety by taking the murderer along, and that if the responsibility were mine I should refuse to take him; but that he, Colonel Rondon, was the superior officer of both the murderer and of all the other enlisted men and army officers on the expedition, and in return was responsible for his actions to his own governmental superiors and to the laws of Brazil; and that in view of this responsibility he must act as his sense of duty bade him. Accordingly, at the next camp he sent back two men, expert woodsmen, to find the murderer and bring him in. They failed to find him.

NOTE: The above account of all the circumstances connected with the murder was read to and approved as correct by all six members of the expedition.

I have anticipated my narrative because I do not wish to recur to the horror more than is necessary. I now return to my story. After we found that Julio had fled, we returned to the scene of the tragedy. The murdered man lay with a handkerchief thrown over his face. We buried him beside the place where he fell. With axes and knives the camaradas dug a shallow grave while we stood by with bared heads. Then reverently and carefully we lifted the poor body which but half an hour before had been so full of vigorous life. Colonel Rondon and I bore the head and shoulders. We laid him in the grave, and heaped a mound over him, and put a rude cross at his head. We fired a volley for a brave and loyal soldier who had died doing his duty. Then we left him forever, under the great trees beside the lonely river.

That day we got only half-way down the rapids. There was no good place to camp. But at the foot of one steep cliff there was a narrow, boulder-covered slope where it was possible to sling hammocks and cook; and a slanting spot was found for my cot, which had sagged until by this time it looked like a broken-backed centipede. It rained a little during the night, but not enough to wet us much. Next day Lyra, Kermit, and Cherrie finished their job, and brought the four remaining canoes to camp, one leaking badly from the battering on the rocks. We then went down-stream a few hundred yards, and camped on the opposite side; it was not a good camping-place, but it was better than the one we left.

The men were growing constantly weaker under the endless strain of exhausting labor. Kermit was having an attack of fever, and Lyra and Cherrie had touches of dysentery, but all three continued to work. While in the water trying to help with an upset canoe I had by my own clumsiness bruised my leg against a boulder; and the resulting inflammation was somewhat bothersome. I now had a sharp attack of fever, but thanks to the excellent care of the doctor, was over it in about forty-eight hours; but Kermit's fever grew worse and he too was unable to work for a day or two. We could walk over the portages, however. A good doctor is an absolute necessity on an exploring expedition in such a country as that we were in, under penalty of a frightful mortality among the members; and the necessary risks and hazards are so great, the chances of disaster so large, that there is no warrant for increasing them by the failure to take all feasible precautions.

The next day we made another long portage round some rapids, and camped at night still in the hot, wet, sunless atmosphere of the gorge. The following day, April 6, we portaged past another set of rapids, which proved to be the last of the rapids of the chasm. For some kilometres we kept passing hills, and feared lest at any moment we might again find ourselves fronting another mountain gorge; with, in such case, further days of grinding and perilous labor ahead of us, while our men were disheartened, weak, and sick. Most of them had already begun to have fever. Their condition was inevitable after over a month's uninterrupted work of the hardest kind in getting through the long series of rapids we had just passed; and a long further delay, accompanied by wearing labor, would have almost certainly meant that the weakest among our party would have begun to die. There were already two of the camaradas who were too weak to help the others, their condition being such as to cause us serious concern.

However, the hills gradually sank into a level plain, and the river carried us through it at a rate that enabled us during the remainder of the day to reel off thirty-six kilometres, a record that for the first time held out promise. Twice tapirs swam the river while we passed, but not near my canoe. However, the previous evening, Cherrie had killed two monkeys and Kermit one, and we all had a few mouthfuls of fresh meat; we had already had a good soup made out of a turtle Kermit had caught. We had to portage by one short set of rapids, the unloaded canoes being brought down without difficulty. At last, at four in the afternoon, we came to the mouth of a big river running in from the right. We thought it was probably the Ananas, but, of course, could not be certain. It was less in volume than the one we had descended, but nearly as broad; its breadth at this point being ninety-five yards as against one hundred and twenty for the larger river. There were rapids ahead, immediately after the junction, which took place in latitude 10 degrees 58 minutes south. We had come 216 kilometres all told, and were nearly north of where we had started. We camped on the point of land between the two rivers. It was extraordinary to realize that here about the eleventh degree we were on such a big river, utterly unknown to the cartographers and not indicated by even a hint on any map. We named this big tributary Rio Cardozo, after a gallant officer of the commission who had died of beriberi just as our expedition began. We spent a day at this spot, determining our exact position by the sun, and afterward by the stars, and sending on two men to explore the rapids in advance. They returned with the news that there were big cataracts in them, and that they would form an obstacle to our progress. They had also caught a huge iluroid fish, which furnished an excellent meal for everybody in camp. This evening at sunset the view across the broad river, from our camp where the two rivers joined, was very lovely; and for the first time we had an open space in front of and above us, so that after nightfall the stars, and the great waxing moon, were glorious over-head, and against the rocks in midstream the broken water gleamed like tossing silver.

The huge catfish which the men had caught was over three feet and a half long, with the usual enormous head, out of all proportions to the body, and the enormous mouth, out of all proportion to the head. Such fish, although their teeth are small, swallow very large prey. This one contained the nearly digested remains of a monkey. Probably the monkey had been seized while drinking from the end of a branch; and once engulfed in that yawning cavern there was no escape. We Americans were astounded at the idea of a catfish making prey of a monkey; but our Brazilian friends told us that in the lower Madeira and the part of the Amazon near its mouth there is a still more gigantic catfish which in similar fashion occasionally makes prey of man. This is a grayish-white fish over nine feet long, with the usual disproportionately large head and gaping mouth, with a circle of small teeth; for the engulfing mouth itself is the danger, not the teeth. It is called the piraiba—pronounced in four syllables. While stationed at the small city of Itacoatiara, on the Amazon, at the mouth of the Madeira, the doctor had seen one of these monsters which had been killed by the two men it had attacked. They were fishing in a canoe when it rose from the bottom—for it is a ground fish—and raising itself half out of the water lunged over the edge of the canoe at them, with open mouth. They killed it with their falcons, as machetes are called in Brazil. It was taken round the city in triumph in an oxcart; the doctor saw it, and said it was three metres long. He said that swimmers feared it even more than the big cayman, because they could see the latter, whereas the former lay hid at the bottom of the water. Colonel Rondon said that in many villages where he had been on the lower Madeira the people had built stockaded enclosures in the water in which they bathed, not venturing to swim in the open water for fear of the piraiba and the big cayman.

Next day, April 8, we made five kilometres only, as there was a succession of rapids. We had to carry the loads past two of them, but ran the canoes without difficulty, for on the west side were long canals of swift water through the forest. The river had been higher, but was still very high, and the current raced round the many islands that at this point divided the channel. At four we made camp at the head of another stretch of rapids, over which the Canadian canoes would have danced without shipping a teaspoonful of water, but which our dugouts could only run empty. Cherrie killed three monkeys and Lyra caught two big piranhas, so that we were again all of us well provided with dinner and breakfast. When a number of men, doing hard work, are most of the time on half-rations, they grow to take a lively interest in any reasonably full meal that does arrive.

On the 10th we repeated the proceedings: a short quick run; a few hundred metres' portage, occupying, however, at least a couple of hours; again a few minutes' run; again other rapids. We again made less than five kilometres; in the two days we had been descending nearly a metre for every kilometre we made in advance; and it hardly seemed as if this state of things could last, for the aneroid showed that we were getting very low down. How I longed for a big Maine birch-bark, such as that in which I once went down the Mattawamkeag at high water! It would have slipped down these rapids as a girl trips through a country dance. But our loaded dugouts would have shoved their noses under every curl. The country was lovely. The wide river, now in one channel, now in several channels, wound among hills; the shower-freshened forest glistened in the sunlight; the many kinds of beautiful palm-fronds and the huge pacova-leaves stamped the peculiar look of the tropics on the whole landscape—it was like passing by water through a gigantic botanical garden. In the afternoon we got an elderly toucan, a piranha, and a reasonably edible side-necked river- turtle; so we had fresh meat again. We slept as usual in earshot of rapids. We had been out six weeks, and almost all the time we had been engaged in wearily working our own way down and past rapid after rapid. Rapids are by far the most dangerous enemies of explorers and travellers who journey along these rivers.

Next day was a repetition of the same work. All the morning was spent in getting the loads to the foot of the rapids at the head of which we were encamped, down which the canoes were run empty. Then for thirty or forty minutes we ran down the swift, twisting river, the two lashed canoes almost coming to grief at one spot where a swirl of the current threw them against some trees on a small submerged island. Then we came to another set of rapids, carried the baggage down past them, and made camp long after dark in the rain—a good exercise in patience for those of us who were still suffering somewhat from fever. No one was in really buoyant health. For some weeks we had been sharing part of the contents of our boxes with the camaradas; but our food was not very satisfying to them. They needed quantity and the mainstay of each of their meals was a mass of palmitas; but on this day they had no time to cut down palms. We finally decided to run these rapids with the empty canoes, and they came down in safety. On such a trip it is highly undesirable to take any save necessary risks, for the consequences of disaster are too serious; and yet if no risks are taken the progress is so slow that disaster comes anyhow; and it is necessary perpetually to vary the terms of the perpetual working compromise between rashness and over-caution. This night we had a very good fish to eat, a big silvery fellow called a pescada, of a kind we had not caught before.

One day Trigueiro failed to embark with the rest of us, and we had to camp where we were next day to find him. Easter Sunday we spent in the fashion with which we were altogether too familiar. We only ran in a clear course for ten minutes all told, and spent eight hours in portaging the loads past rapids down which the canoes were run; the balsa was almost swamped. This day we caught twenty-eight big fish, mostly piranhas, and everybody had all he could eat for dinner, and for breakfast the following morning.

The forenoon of the following day was a repetition of this wearisome work; but late in the afternoon the river began to run in long quiet reaches. We made fifteen kilometres, and for the first time in several weeks camped where we did not hear the rapids. The silence was soothing and restful. The following day, April 14, we made a good run of some thirty-two kilometres. We passed a little river which entered on our left. We ran two or three light rapids, and portaged the loads by another. The river ran in long and usually tranquil stretches. In the morning when we started the view was lovely. There was a mist, and for a couple of miles the great river, broad and quiet, ran between the high walls of tropical forest, the tops of the giant trees showing dim through the haze. Different members of the party caught many fish, and shot a monkey and a couple of jacare-tinga birds kin to a turkey, but the size of a fowl—so we again had a camp of plenty. The dry season was approaching, but there were still heavy, drenching rains. On this day the men found some new nuts of which they liked the taste; but the nuts proved unwholesome and half of the men were very sick and unable to work the following day. In the balsa only two were left fit to do anything, and Kermit plied a paddle all day long.

Accordingly, it was a rather sorry crew that embarked the following morning, April 15. But it turned out a red-letter day. The day before, we had come across cuttings, a year old, which were probably but not certainly made by pioneer rubbermen. But on this day—during which we made twenty-five kilometres—after running two hours and a half we found on the left bank a board on a post, with the initials J. A., to show the farthest up point which a rubberman had reached and claimed as his own. An hour farther down we came on a newly built house in a little planted clearing; and we cheered heartily. No one was at home, but the house, of palm thatch, was clean and cool. A couple of dogs were on watch, and the belongings showed that a man, a woman, and a child lived there, and had only just left. Another hour brought us to a similar house where dwelt an old black man, who showed the innate courtesy of the Brazilian peasant. We came on these rubbermen and their houses in about latitude 10 degrees 24 minutes.

In mid-afternoon we stopped at another clean, cool, picturesque house of palm thatch. The inhabitants all fled at our approach, fearing an Indian raid; for they were absolutely unprepared to have any one come from the unknown regions up-stream. They returned and were most hospitable and communicative; and we spent the night there. Said Antonio Correa to Kermit: "It seems like a dream to be in a house again, and hear the voices of men and women, instead of being among those mountains and rapids." The river was known to them as the Castanho, and was the main affluent or rather the left or western branch, of the Aripuanan; the Castanho is a name used by the rubber- gatherers only; it is unknown to the geographers. We were, according to our informants, about fifteen days' journey from the confluence of the two rivers; but there were many rubbermen along the banks, some of whom had become permanent settlers. We had come over three hundred kilometres, in forty-eight days, over absolutely unknown ground; we had seen no human being, although we had twice heard Indians. Six weeks had been spent in steadily slogging our way down through the interminable series of rapids. It was astonishing before, when we were on a river of about the size of the upper Rhine or Elbe, to realize that no geographer had any idea of its existence. But, after all, no civilized man of any grade had ever been on it. Here, however, was a river with people dwelling along the banks, some of whom had lived in the neighborhood for eight or ten years; and yet on no standard map was there a hint of the river's existence. We were putting on the map a river, running through between five and six degrees of latitude—of between seven and eight if, as should properly be done, the lower Aripuanan is included as part of it—of which no geographer, in any map published in Europe, or the United States, or Brazil had even admitted the possibility of the existence; for the place actually occupied by it was filled, on the maps, by other—imaginary—streams, or by mountain ranges. Before we started, the Amazonas Boundary Commission had come up the lower Aripuanan and then the eastern branch, or upper Aripuanan, to 8 degrees 48 minutes, following the course which for a couple of decades had been followed by the rubbermen, but not going as high. An employee, either of this commission or of one of the big rubbermen, had been up the Castanho, which is easy of ascent in its lower course, to about the same latitude, not going nearly as high as the rubbermen had gone; this we found out while we ourselves were descending the lower Castanho. The lower main stream, and the lower portion of its main affluent, the Castanho, had been commercial highways for rubbermen and settlers for nearly two decades, and, as we speedily found, were as easy to traverse as the upper stream, which we had just come down, was difficult to traverse; but the governmental and scientific authorities, native and foreign, remained in complete ignorance; and the rubbermen themselves had not the slightest idea of the headwaters, which were in country never hitherto traversed by civilized men. Evidently the Castanho was, in length at least, substantially equal, and probably superior, to the upper Aripuanan; it now seemed even more likely that the Ananas was the headwaters of the main stream than of the Cardozo.

For the first time this great river, the greatest affluent of the Madiera, was to be put on the map; and the understanding of its real position and real relationship, and the clearing up of the complex problem of the sources of all these lower right-hand affluents of the Madiera, was rendered possible by the seven weeks of hard and dangerous labor we had spent in going down an absolutely unknown river, through an absolutely unknown wilderness. At this stage of the growth of world geography I esteemed it a great piece of good fortune to be able to take part in such a feat—a feat which represented the capping of the pyramid which during the previous seven years had been built by the labor of the Brazilian Telegraphic Commission.

We had passed the period when there was a chance of peril, of disaster, to the whole expedition. There might be risk ahead to individuals, and some difficulties and annoyances for all of us; but there was no longer the least likelihood of any disaster to the expedition as a whole. We now no longer had to face continual anxiety, the need of constant economy with food, the duty of labor with no end in sight, and bitter uncertainty as to the future.

It was time to get out. The wearing work, under very unhealthy conditions, was beginning to tell on every one. Half of the camaradas had been down with fever and were much weakened; only a few of them retained their original physical and moral strength. Cherrie and Kermit had recovered; but both Kermit and Lyra still had bad sores on their legs, from the bruises received in the water work. I was in worse shape. The after effects of the fever still hung on; and the leg which had been hurt while working in the rapids with the sunken canoe had taken a turn for the bad and developed an abscess. The good doctor, to whose unwearied care and kindness I owe much, had cut it open and inserted a drainage tube; an added charm being given the operation, and the subsequent dressings, by the enthusiasm with which the piums and boroshudas took part therein. I could hardly hobble, and was pretty well laid up. But "there aren't no 'stop, conductor,' while a battery's changing ground." No man has any business to go on such a trip as ours unless he will refuse to jeopardize the welfare of his associates by any delay caused by a weakness or ailment of his. It is his duty to go forward, if necessary on all fours, until he drops. Fortunately, I was put to no such test. I remained in good shape until we had passed the last of the rapids of the chasms. When my serious trouble came we had only canoe-riding ahead of us. It is not ideal for a sick man to spend the hottest hours of the day stretched on the boxes in the bottom of a small open dugout, under the well-nigh intolerable heat of the torrid sun of the mid-tropics, varied by blinding, drenching downpours of rain; but I could not be sufficiently grateful for the chance. Kermit and Cherrie took care of me as if they had been trained nurses; and Colonel Rondon and Lyra were no less thoughtful.

The north was calling strongly to the three men of the north—Rocky Dell Farm to Cherrie, Sagamore Hill to me; and to Kermit the call was stronger still. After nightfall we could now see the Dipper well above the horizon—upside down, with the two pointers pointing to a north star below the world's rim; but the Dipper, with all its stars. In our home country spring had now come, the wonderful northern spring of long glorious days, of brooding twilights, of cool delightful nights. Robin and bluebird, meadow-lark and song sparrow, were singing in the mornings at home; the maple-buds were red; windflowers and bloodroot were blooming while the last patches of snow still lingered; the rapture of the hermithrush in Vermont, the serene golden melody of the woodthrush on Long Island, would be heard before we were there to listen. Each man to his home, and to his true love! Each was longing for the homely things that were so dear to him, for the home people who were dearer still, and for the one who was dearest of all.



X. TO THE AMAZON AND HOME; ZOOLOGICAL AND GEOGRAPHICAL RESULTS OF THE EXPEDITION

Our adventures and our troubles were alike over. We now experienced the incalculable contrast between descending a known and travelled river, and one that is utterly unknown. After four days we hired a rubberman to go with us as guide. We knew exactly what channels were passable when we came to the rapids, when the canoes had to unload, and where the carry-trails were. It was all child's play compared to what we had gone through. We made long days' journeys, for at night we stopped at some palm-thatched house, inhabited or abandoned, and therefore the men were spared the labor of making camp; and we bought ample food for them, so there was no further need of fishing and chopping down palms for the palmtops. The heat of the sun was blazing; but it looked as if we had come back into the rainy season, for there were many heavy rains, usually in the afternoon, but sometimes in the morning or at night. The mosquitoes were sometimes rather troublesome at night. In the daytime the piums swarmed, and often bothered us even when we were in midstream.

For four days there were no rapids we could not run without unloading. Then, on the 19th, we got a canoe from Senhor Barboso. He was a most kind and hospitable man, who also gave us a duck and a chicken and some mandioc and six pounds of rice, and would take no payment; he lived in a roomy house with his dusky, cigar-smoking wife and his many children. The new canoe was light and roomy, and we were able to rig up a low shelter under which I could lie; I was still sick. At noon we passed the mouth of a big river, the Rio Branco, coming in from the left; this was about in latitude 9 degrees 38 minutes. Soon afterward we came to the first serious rapids, the Panela. We carried the boats past, ran down the empty canoes, and camped at the foot in a roomy house. The doctor bought a handsome trumpeter bird, very friendly and confiding, which was thenceforth my canoe companion.

We had already passed many inhabited—and a still larger number of uninhabited—houses. The dwellers were rubbermen, but generally they were permanent settlers also, homemakers, with their wives and children. Some, both of the men and women, were apparently of pure negro blood, or of pure Indian or south European blood; but in the great majority all three strains were mixed in varying degrees. They were most friendly, courteous, and hospitable. Often they refused payment for what they could afford, out of their little, to give us. When they did charge, the prices were very high, as was but just, for they live back of the beyond, and everything costs them fabulously, save what they raise themselves. The cool, bare houses of poles and palm thatch contained little except hammocks and a few simple cooking utensils; and often a clock or sewing machine, or Winchester rifle, from our own country. They often had flowers planted, including fragrant roses. Their only live stock, except the dogs, were a few chickens and ducks. They planted patches of mandioc, maize, sugarcane, rice, beans, squashes, pineapples, bananas, lemons, oranges, melons, peppers; and various purely native fruits and vegetables, such as the kniabo—a vegetable-fruit growing on the branches of a high bush— which is cooked with meat. They get some game from the forest, and more fish from the river. There is no representative of the government among them—indeed, even now their very existence is barely known to the governmental authorities; and the church has ignored them as completely as the state. When they wish to get married they have to spend several months getting down to and back from Manaos or some smaller city; and usually the first christening and the marriage ceremony are held at the same time. They have merely squatter's right to the land, and are always in danger of being ousted by unscrupulous big men who come in late, but with a title technically straight. The land laws should be shaped so as to give each of these pioneer settlers the land he actually takes up and cultivates, and upon which he makes his home. The small homemaker, who owns the land which he tills with his own hands, is the greatest element of strength in any country.

These are real pioneer settlers. They are the true wilderness-winners. No continent is ever really conquered, or thoroughly explored, by a few leaders, or exceptional men, although such men can render great service. The real conquest, the thorough exploration and settlement, is made by a nameless multitude of small men of whom the most important are, of course, the home-makers. Each treads most of the time in the footsteps of his predecessors, but for some few miles, at some time or other, he breaks new ground; and his house is built where no house has ever stood before. Such a man, the real pioneer, must have no strong desire for social life and no need, probably no knowledge, of any luxury, or of any comfort save of the most elementary kind. The pioneer who is always longing for the comfort and luxury of civilization, and especially of great cities, is no real pioneer at all. These settlers whom we met were contented to live in the wilderness. They had found the climate healthy and the soil fruitful; a visit to a city was a very rare event, nor was there any overwhelming desire for it.

In short, these men, and those like them everywhere on the frontier between civilization and savagery in Brazil, are now playing the part played by our backwoodsmen when over a century and a quarter ago they began the conquest of the great basin of the Mississippi; the part played by the Boer farmers for over a century in South Africa, and by the Canadians when less than half a century ago they began to take possession of their Northwest. Every now and then some one says that the "last frontier" is now to be found in Canada or Africa, and that it has almost vanished. On a far larger scale this frontier is to be found in Brazil—a country as big as Europe or the United States—and decades will pass before it vanishes. The first settlers came to Brazil a century before the first settlers came to the United States and Canada. For three hundred years progress was very slow—Portuguese colonial government at that time was almost as bad as Spanish. For the last half-century and over there has been a steady increase in the rapidity of the rate of development; and this increase bids fair to be constantly more rapid in the future.

The Paolistas, hunting for lands, slaves, and mines, were the first native Brazilians who, a hundred years ago, played a great part in opening to settlement vast stretches of wilderness. The rubber hunters have played a similar part during the last few decades. Rubber dazzled them, as gold and diamonds have dazzled other men and driven them forth to wander through the wide waste spaces of the world. Searching for rubber they made highways of rivers the very existence of which was unknown to the governmental authorities, or to any map-makers. Whether they succeeded or failed, they everywhere left behind them settlers, who toiled, married, and brought up children. Settlement began; the conquest of the wilderness entered on its first stage.

On the 20th we stopped at the first store, where we bought, of course at a high price, sugar and tobacco for the camaradas. In this land of plenty the camaradas over-ate, and sickness was as rife among them as ever. In Cherrie's boat he himself and the steersman were the only men who paddled strongly and continuously. The storekeeper's stock of goods was very low, only what he still had left from that brought in nearly a year before; for the big boats, or batelaos-batelons—had not yet worked as far up-stream. We expected to meet them somewhere below the next rapids, the Inferno. The trader or rubberman brings up his year's supply of goods in a batelao, starting in February and reaching the upper course of the river early in May, when the rainy season is over. The parties of rubber-explorers are then equipped and provisioned; and the settlers purchase certain necessities, and certain things that strike them as luxuries. This year the Brazil-nut crop on the river had failed, a serious thing for all explorers and wilderness wanderers.

On the 20th we made the longest run we had made, fifty-two kilometres. Lyra took observations where we camped; we were in latitude 8 degrees 49 minutes. At this camping-place the great, beautiful river was a little over three hundred metres wide. We were in an empty house. The marks showed that in the high water, a couple of months back, the river had risen until the lower part of the house was flooded. The difference between the level of the river during the floods and in the dry season is extraordinary.

On the 21st we made another good run, getting down to the Inferno rapids, which are in latitude 8 degrees 19 minutes south. Until we reached the Cardozo we had run almost due north; since then we had been running a little west of north. Before we reached these rapids we stopped at a large, pleasant thatch house, and got a fairly big and roomy as well as light boat, leaving both our two smaller dugouts behind. Above the rapids a small river, the Madeirainha, entered from the left. The rapids had a fall of over ten metres, and the water was very wild and rough. Met with for the first time, it would doubtless have taken several days to explore a passage and, with danger and labor, get the boats down. But we were no longer exploring, pioneering, over unknown country. It is easy to go where other men have prepared the way. We had a guide; we took our baggage down by a carry three-quarters of a kilometre long; and the canoes were run through known channels the following morning. At the foot of the rapids was a big house and store; and camped at the head were a number of rubber-workers, waiting for the big boats of the head rubbermen to work their way up from below. They were a reckless set of brown daredevils. These men lead hard lives of labor and peril; they continually face death themselves, and they think little of it in connection with others. It is small wonder that they sometimes have difficulties with the tribes of utterly wild Indians with whom they are brought in contact, although there is a strong Indian strain in their own blood.

The following morning, after the empty canoes had been run down, we started, and made a rather short afternoon's journey. We had to take the baggage by one rapids. We camped in an empty house, in the rain. Next day we ran nearly fifty kilometres, the river making a long sweep to the west. We met half a dozen batelaos making their way up-stream, each with a crew of six or eight men; and two of them with women and children in addition. The crew were using very long poles, with crooks, or rather the stubs of cut branches which served as crooks, at the upper end. With these they hooked into the branches and dragged themselves up along the bank, in addition to poling where the depth permitted it. The river was as big as the Paraguay at Corumba; but, in striking contrast to the Paraguay, there were few water-birds. We ran some rather stiff rapids, the Infernino, without unloading, in the morning. In the evening we landed for the night at a large, open, shed-like house, where there were two or three pigs, the first live stock we had seen other than poultry and ducks. It was a dirty place, but we got some eggs.

The following day, the 24th, we ran down some fifty kilometres to the Carupanan rapids, which by observation Lyra found to be in latitude 7 degrees 47 minutes. We met several batelaos, and the houses on the bank showed that the settlers were somewhat better off than was the case farther up. At the rapids was a big store, the property of Senhor Caripe, the wealthiest rubberman who works on this river; many of the men we met were in his employ. He has himself risen from the ranks. He was most kind and hospitable, and gave us another boat to replace the last of our shovel-nosed dugouts. The large, open house was cool, clean, and comfortable.

With these began a series of half a dozen sets of rapids, all coming within the next dozen kilometres, and all offering very real obstacles. At one we saw the graves of four men who had perished therein; and many more had died whose bodies were never recovered; the toll of human life had been heavy. Had we been still on an unknown river, pioneering our own way, it would doubtless have taken us at least a fortnight of labor and peril to pass. But it actually took only a day and a half. All the channels were known, all the trails cut. Senhor Caripe, a first-class waterman, cool, fearless, and brawny as a bull, came with us as guide. Half a dozen times the loads were taken out and carried down. At one cataract the canoes were themselves dragged overland; elsewhere they were run down empty, shipping a good deal of water. At the foot of the cataract, where we dragged the canoes overland, we camped for the night. Here Kermit shot a big cayman. Our camp was alongside the graves of three men who at this point had perished in the swift water.

Senhor Caripe told us many strange adventures of rubber-workers he had met or employed. One of his men, working on the Gy-Parana, got lost and after twenty-eight days found himself on the Madeirainha, which he thus discovered. He was in excellent health, for he had means to start a fire, and he found abundance of Brazil-nuts and big land-tortoises. Senhor Caripe said that the rubbermen now did not go above the ninth degree, or thereabouts, on the upper Aripuanan proper, having found the rubber poor on the reaches above. A year previously five rubbermen, Mundurucu Indians, were working on the Corumba at about that level. It is a difficult stream to ascend or descend. They made excursions into the forest for days at a time after caoutchouc. On one such trip, after fifteen days they, to their surprise, came out on the Aripuanan. They returned and told their "patron" of their discovery; and by his orders took their caoutchouc overland to the Aripuanan, built a canoe, and ran down with their caoutchouc to Manaos. They had now returned and were working on the upper Aripuanan. The Mundurucus and Brazilians are always on the best terms, and the former are even more inveterate enemies of the wild Indians than are the latter.

By mid-forenoon on April 26 we had passed the last dangerous rapids. The paddles were plied with hearty good will, Cherrie and Kermit, as usual, working like the camaradas, and the canoes went dancing down the broad, rapid river. The equatorial forest crowded on either hand to the water's edge; and, although the river was falling, it was still so high that in many places little islands were completely submerged, and the current raced among the trunks of the green trees. At one o'clock we came to the mouth of the Castanho proper, and in sight of the tent of Lieutenant Pyrineus, with the flags of the United States and Brazil flying before it; and, with rifles firing from the canoes and the shore, we moored at the landing of the neat, soldierly, well kept camp. The upper Aripuanan, a river of substantially the same volume as the Castanho, but broader at this point, and probably of less length, here joined the Castanho from the east, and the two together formed what the rubbermen called the lower Aripuanan. The mouth of this was indicated, and sometimes named, on the maps, but only as a small and unimportant stream.
