Hill warned me late one afternoon to be ready to start at sunrise, and then went to play poker. On my way to my hut, at sunset, I stopped to gossip with the young doctor, where he was busy dressing wounds at his surgery. The labourers, half-breeds, Brazilians, and Bolivian Spaniards, work being over, were giving the doctor a full evening with their ailments. Mostly these were skin troubles. The least abrasion in the tropics may spread to a horrid and persistent wound. The legs of the majority of these natives were unpleasant with livid scars. In one case a vampire bat had punctured a man’s arm near the elbow while he slept, and that little wound had grown disastrously. We were in a region where the pium flies swarmed, tiny black insects which alight on the hands and face, perhaps a dozen at a time, and gorge themselves, though you may be unconscious of it. Where the pium fly feeds it leaves a dot of extravasated blood which remains for weeks, so that most of us were speckled. Even these minute wounds were liable to become deep and bad. There were larger flies which put their eggs in the human body, where they hatch with dire results. (Do not think the splendid tropics have nothing but verdure, orchids, butterflies, and coral snakes banded orange and black and crimson and black.) So the doctor was a busy man that evening. The floor of his surgery was made of unequal boughs; the walls and roof were of dried fronds. A lamp was slung on a doorpost. He was a young American, and he did not grumble at his bumpy floor, the bad light, the appliances and remedies which were all one should expect in the jungle, nor the number of his patients, except comically. He told me he was rather keen on the diseases of the tropics. He liked them. (I should think he must have liked them.) He was merrily insolent with those swarthy and melancholy men, and they smiled back sadly at the clever, handsome, and lively youngster. He was quick in his decisions, deft, insistent, kind, and thorough, working down that file of pitiable humanity, as careful with the last of the long row as with the first; telling me, as he went along, much that I had never heard before, with demonstrations. “Don’t go,” he cried, when I would have left him; for I thought it might be he was as kind with this stranger as he was with the others. “Ah! don’t go. Let me hear a true word or two.” He said he would give me a treat if I stayed. He finished, put his materials away deliberately, accurately, his back to me, while I saluted him as a fine representative of ours. He turned, free of his task and jolly, and produced that treat of his, two bottles of treasured and precious ginger ale. It was a miracle performed. We talked till the light went out.

Much later a cry in the woods woke me. It was yet dark, but I could see Hill up, and fumbling with his accoutrements. Out I jumped, though still unreasonably tired; and sleepily dressed. When I turned to Hill, to see if he were ready, he was then under his net, watching me. He explained he had just returned from poker, and was wondering why I was dressing, but did not like to ask, knowing that Englishmen have ways that are not American. So the sun was up long before we were, though presently, in a small canoe, we embarked on the Caracoles. This tributary of the Madeira comes from nobody knows where. It is a river of the kind which explorers in these forests have sometimes mentioned, to our fearful joy. The sunlight hardly reached the water. The river was merely a drain burrowing under the jungle. The forest on its banks met overhead. There was little foliage below; we saw but the base of the forest, grey columns that might have been of stone upholding a darkness from which dead stuff suspended. The canoe had to dodge the lianas, which dropped to the water. The noise of our paddles convoyed us down stream, a rout of panic echoes trying to escape. We came to an opening and full daylight presently, and landed by a mule corral; and I began a lonely ride with Hill through the forest. The mule was such a docile little brown creature that I was left in the silence to my thoughts, which were interrupted now and then by the wandering blue flame of a morpho. My mule followed Hill’s mule along a winding trail, and our leader was nearly always out of sight. I do not remember much of my first ride in the forest. I had an impression of being at a viewless distance from the sun. We were on the abysmal floor of a growth which was not trees, but the hoary pediments of a structure which was too high and vast for human sight. We rode in the basal gloom of it, no more than lost ants there, at an immeasurable depth in the atmosphere. The roof of the world was far away. Somewhere was the sun, for occasionally there was a well which its light had filled, and a grove of green palms, complete and personal, standing at the bottom of the well, living and reasonable shapes. Or one of the morphos would flicker among those spectral bastions, aerial and bright as a fairy in Hades. The sombre mind caught it at once, an unexpected gleam of hope, a bright blue thought to set among one’s shapeless fears. We descended into hollows, going down into darker fathoms of the shades; mounted again through brighter suffusions of day, and in a while came out upon the open lane in the woods, the long cut in the jungle made for the railway, when it should get so far.

Now I could see my companion. He was from Texas, and it was easy to guess that. In the long rides which followed in the land where we looked upon what was there for the first time since genesis, where we might have been in the hush of the seventh day, so new, strange, and quiet was all, the figure ahead of me, with its long boots, negligent black shirt, the guns about the waist, and the hat with its extravagant size nobly raked, made me stop at times to assure myself that I was not pursuing a day-dream of boyhood, too much Mayne Reid in my head, especially when my wild and improbable companion paused under a group of statuesque palms and looked back at me—I suppose to make sure that I was still there, and that the silence had not absorbed me utterly, a faint rustle of intruding sound in a virgin and absorbent world. And again I remember the sparkle and lift of early morning there. The air was new, it was stimulative, it recharged me with buoyant youth. To breathe that air in the fresh of the morning was exaltation, and to see the young sunlight on the ardent foliage was to know the springs of life were full. That was at the breakfast hour, when the camp fires crackled and were aromatic, the smoke going straight to the tree tops. Then quickly the narrow track through the forest filled with day, increased in heat till I felt I could bear no more of it, and so gazed vacantly at the mule’s ears, merely enduring and numbed. The vitality of the morning went, and in the fierce pour of light I looked no more to the strange leaves and vines, the curious fronds, the anthills by the way, the butterflies and birds, but had only a dull dread that the avenue through which we were riding was straight and interminable. There was no escape from this heat. There were no openings through which we could retreat under the trees. The air was immobile; the air itself was the incumbent heat. The only shadows were under the mules’ bellies. Cruel and relentless noons! How the surveyors endured it, standing for long eyeing their exacting instruments in such a defeating glare, I do not know. At the end of each day my pigskin leggings were like wet brown paper with sweat, and my hands crinkled and bleached as though they had been in a soda bath.

We reached another and greater tributary of the Madeira, the Rio Jaci-Parana. Here there was a very extensive clearing as great as the one at Porto Velho. The bridging of the Jaci would be a considerable undertaking, consequently there were numerous huts dotted about the rough open ground; but I think the original intention in cutting back the jungle to such an extent was that in the days to come a town would grow there. I imagine it will not, and that the project is abandoned. In one of my early walks in the woods I came by chance upon the new cemetery; it was already large. The Jaci country has proved to be more than usually unhealthy. The ground was cleared down to a coarse herbage, round which stood shadowing trees. Little crucifixes, made by splitting a stick and putting another stick crosswise in the slit, were planted at all sorts of drunken angles in the ground. One large cross in the centre stood for all the dead. There were no names given. A Brazil nut-tree grew alongside this graveyard in the jungle, so tall that the flock of screaming parrots about its foliage were but drifting black specks.

Because Hill had a touch of the fever we stayed for some days by the Jaci. I had a hut given to me, typical of the rest; but I was so much alone in it that that hut on the Jaci, where our remoteness from human things tested and known, the aloofness and quiet of the forest, the deadly nature of the romantic and beautiful river bank where we were marooned, and the sickness of my friend Hill, threw me upon my centre, until I began even to talk to myself, and received such an impress of the minute details of my little habitation that, ephemeral as it was and now long since gone, it endures, of coloured and indestructible stuff, with a sunny portal I still can enter whenever my mind turns that way. It was of four palm trunks, lapped round and over with mats of leaves. The floor was of untrimmed branches, two feet from the earth, and their unexpected inequalities, never remembered, were always jolting my thoughts as I walked across. They were crooked, and I could see the dusty earth two feet beneath where brown and green lizards ran. At one end was a verandah with a narrow floor made of the lids of soap and dynamite boxes, and laid without any idea that some curious tenant might wish to read the manufacturers’ full names and see their complete trademarks. It was a puzzle. There was nothing to do, and I searched long on my verandah floor for the clue to one embarrassing fragment of a stencilled word. Hill sometimes huddled in a hammock on one side of the verandah, a leg hanging limply over, his thin sallow face drawn and resting on his breast, and his eyes shut; and I sat near him on the rail, silent, alone with any thought I met, and gazing blankly down the steep slope, past two tall Brazil nut-trees, to the half-hidden Rio Jaci below, and the roof of the forest opposite, over which the sun set each day in uplifted splendour. I remembered but one conversation during that wait. An elderly white man came up to the verandah one evening, and murmured something to Hill, who opened his eyes, and looked at his visitor under weary lids. This man was one of Hill’s subordinates. He had something to say of the work; but one would hardly call it speech. The flow of his life was so weak that he could do no more than lift a few small words from his gaping mouth between his breaths. He held on to the verandah. His loose clothes hung straight down from his bones. The veins were in blue knots on his forehead. “Say,” said Hill, rousing himself, “I want you to ride to the Caracoles, go down to Porto Velho, and take this note to the hospital.” The man said nothing, but nodded. Hill scrawled his note, and the man left. “He’ll be dead in a month,” said Hill, five minutes after the man had gone. “But he would not go to the hospital for his health. I have to pretend that he must go for mine. He may as well die in a comfortable bed.... I wish those damned parrots would cease!” They were somewhere down by the river, unseen, but all the sound there was, their voices long, keen and distracting flaws in the pellucid and coloured dayfall.

One morning we crossed the Jaci, and on the opposite shore some mules were already geared with Texan saddles, the hombres at their heads, waiting for us. I considered my mule. He was a big, grey, upstanding fellow, with the legs and feet of a racehorse, the head of a hammer, and alert and inquisitive ears. He was very much alive. I had no doubt he could leave anywhere like light, when he had a mind for it. So that I turned to Hill, and said, “Is mine a quiet animal? Is he vicious?” “O say,” said my guide, glancing carelessly at my dubious mount, “I guess he’s just a mule.” When a hombre shouted at my mule he stepped briskly, with more than a hint of the malicious rebel in his gait.

I knew it would happen, and it did. One foot was no sooner buried in a wooden shoe called a stirrup than he was off, like an explosion. A desperate leap got my other leg over my travelling sack, lashed on his rump, and I came down in the saddle, much surprised. Texan saddles are not leather pads for riding domestic creatures, but thrones for ruling devils, and the bit would have broken the mouth of a hippopotamus. The brute stopped, turned back one ear, and his thought was in his swivel eye. “You wait,” I saw him say. In the few engrossing moments when his body was expanding and contracting under me I got some idea of the force I was supposed to guide, and it did not make my mind easy, for an office chair had been my most unstable seat till then. Yet off we went quietly, along the track, and Hill was in front, and my mule was as meek as a sheep. There came a swamp, into which he went to the knees, and I dismounted, jumping from hummock to hummock, encouraging him, and showing him the best places. His brown eyes were then like those of a good woman. So leaning forward, when we were through, I patted his sleek neck, and gave him pleasant words. Afterwards, when he showed a certain precious care in difficult places, for the country was very broken, stepping like a tight-rope walker, I was fool enough to think it was because of our understanding. Though I believe he would have deceived anybody.

At noon we left the track and entered the forest by a path so narrow that the trees touched our legs, and sometimes we had just time to duck beneath a noose which a liana dangled in our faces. It was a low and narrow tunnel, and it descended to a bottom where a shallow stream brawled among granite boulders; thence up the trail went through the trees and vines again, and at last we came to a little clearing, where there was a hut, and men who would give us meat and drink. We dismounted. I rubbed my mule’s soft nose, and spoke him playfully, as a familiar; but when entering the hut was rebuked by a man there for making a short cut round the heels of my mule. “Never do it. Don’t give him a chance. A mule will be peaches for ten years waiting for the sure chance of getting his heels right on your stomach. They’re not horses, them mules. They don’t bite, and they don’t muzzle you and show friendly. They’ve got no feelings. That chap of yours, his mother was an ass, and his father was old Solfernio himself. But they’ve all got one good point—they’re barren.”

The mule stood deep in thought till I was mounted again; then instantly bolted back along the path which led to the ravine. The idle hombre had mishandled the reins, and I could get no pull. I went across that clearing like (so Hill said afterwards) Tod Sloan up. The beast, his ears back, was in a frenzy, and the convulsions of his powerful body made my thoughts pallid and ghastly. Nothing but disaster could stop him, and the black mouth of that steep tunnel in the forest yawned before us, and grew larger, though not large enough. He took the opening as clean as a lucky shot; but I was laid carefully along his back. Why we missed the tangle of woods and the rocks in that precipitate descent is known only to my lucky stars. I had my feet from the stirrups, my toes hooked on his rump, one arm round the horn of the saddle, and the other stretched along his sawing neck. I saw the roots and stones leap up and by us, close to my face. Several things occurred to me, and one was that some methods of dire fate were fatuous and undignified. I wondered also whether I should be taken back to the ship, or buried there. The impetus of the brute, which I expected would send us somersaulting among the rocks of the bottom, took him partly up the hither slope, and soon he had to gather his haunches for the upward leaps. I slipped off. He swung round at the length of the reins, and eyed me, cocking his ears derisively. A horse’s nerves are human-like, and a horse would have been in a muck, but this murderous mule was calm and mocking. I watched him, and listened for an obscene and confident guffaw.
