There was a man who looked like a sensational ruffian who boarded us one morning at Porto Velho, and said he had come to find me. He was going up into the forest, beyond the track, and would I go with him? That made me look at him again, and with some anxiety; for I had tried before to get away, but the crowd on the “Capella” disliked the idea. The Doctor talked dysentery and things. He said it was safer to keep to the ship during the month we had still to spend at Porto Velho. I felt, overborne by their arguments, a rather thin sort of adventurer. That mysterious railway would have drawn the mind of any man who had not lost his curiosity, and who valued being alive more than his chance of old age. The track went from Porto Velho into outer darkness. It left the clearing and the village of mushroom buildings, the place where the inhuman had been moderately subdued, where a modicum of industry was established in a continent of primitive wild, crossed a creek by a trestle bridge in view of our steamer, and vanished; that was the end of it, so far as we knew. Men came back to the settlement through that hole of the forest, and boarded the “Capella” to tell us, in long hot nights, something of what the forest of the Madeira was hiding; and they were bearded like Crusoe, pallid as anæmic women, and speckled with insect bites. These men said that where they had been working the sun never shone, for his light was stopped on the unbroken green which, except where the big rivers flowed, roofed the whole land. I liked the look of the stranger who had come to persuade me to this rare holiday. He said his name was Marion Hill, of Texas. He wore muddy riding breeches, and a black shirt open at the throat, and boots of intricately embossed leather which came well up his thighs, spurs that would have ravelled a pachyderm, and the insolent hat of a bandit. He had a waistbelt heavy with guns and ammunition. I saw his face, and divined instantly that this was a man, and that the memory of a time with him would serve me as a refuge in the grey and barren years, and as a solace. I told him I would get my things together. The Skipper called after me that if I returned too late I should have to walk home.
There was a commissary train next morning, taking men and supplies to the camps. It had a number of open waggons, loaded with material, about which the labourers going up to replenish the gangs made themselves as comfortable as they could. I had an indiarubber bag for all my belongings, being told that it was best for strapping to a mule, and a valuable lifebuoy when a canoe overturned. I accepted it with perfect faith, for I knew nothing of mules or canoes. The train moved off, a bell on the engine ringing sepulchrally. Hill and I were packed into a box car, which had a door open on either side for light and air. Two American engineers were in charge, there was an Austrian to superintend the distribution at each camp of the provisions, the Austrian had an Italian assistant, and a few Barbadian blacks were there to move about the packages. I sat on a case of tinned fruit. Hill reposed on one of the shelves where we should stow fever victims, when we collected them. There was no more room in the car, and another degree of heat would have meant complete ruin.
When Porto Velho is left for the place where the line is to end, when completed, though it is but 250 miles away, two months at least is required for the return journey. That way goes the paymaster, with his armed escort, and every bundle of shovels and tin of provisions. When I went, too, the train helped for sixty miles. Then most of the material was transported at the Rio Caracoles, a tributary of the Madeira, and taken by boats in stages up the main stream, cargoes and boats being hauled round each cataract. Travellers could shorten the journey by going overland part of the way, mules being kept on the hither side of the Caracoles river for that purpose.
We delivered some patients at the hospital, went through a cutting of red granite to the back of San Antonio, and then entered the forest. That absorbed us. Thenceforward, and until I reached the ship again, I was dominated by the lofty, silent, confused, and brooding growth. Everywhere it was dramatically passionate in its intensity, an arrested riot of green life, and its muteness kept expectant attention fixed upon it. The right of way through the forest was a hundred feet wide. On each side of us the trees rose like virid cliffs. The trees usually were of slender girth, almost as straight as fir poles, rising perhaps for sixty feet without a branch. Occasionally there was a giant, a silk cotton tree, or the strange tree with its grey trunk and pale birch-like habit of foliage which I had noticed on the riverside; but they were not common. Palms were numerous. From ground to high parapet the spaces between the columns were filled with lianas, unrelated big leaves, and the characteristic fronds of the endogens. In this older part of the track, though it had been made but little more than a year, the scrub was dense. The undergrowth was often so strong and aggressive as to brush the train as we slowly bumped along. Sometimes we went through deep cuttings in the red clay, close enough for me to notice it was interstratified with waterworn but angular quartz peebles. But the track usually was over flat country, only rarely crossing a gulley.
At every maintenance camp we stopped to deliver supplies. From out of a small huddle of shanties made of leaves and poles, insignificant beneath the forest wall, a number of languid half-breeds, merely in pants and hats, would loiter through the hot sun to us for their sustenance. The men of those secluded huts must have been glad of our temporary uproar, and our new faces. The bell rang, and we left them to burial in their deep silence again. There were intervening camps, which had been deserted as the work progressed. These were even more interesting to me. The work of the human, when he leaves it to the wild from which he has won it with so much pain, has an appeal of its own, with its abandoned ruin returning to the ground again. There would be a sandy swamp, and standing back from the line some weather-worn shanties with roofs awry. I am sure there were ghosts in those camps. One we passed, and it was called Camp 10-1/2, and resting against its open front where the posts were giving was a butterfly net. I pointed this out. “Oh, that,” said Hill. “Old man Biddell. I knew him. He was all right. He was great on bugs and butterflies. Used to wear spectacles. He was a good engineer though. Died of blackwater fever before the line got past this camp. That was his shack.” And that was his butterfly net, all of Biddell now, his sole monument and reminder. As we bumped by the huts the helicons and swallow tails rose precipitously from the mangled cans and cast rubbish. I never knew Biddell, the man with spectacles and a butterfly net, but a first rate railway man, who left that net outside his hut one morning, and at evening was buried, but now I am doomed to think of him while I live.
It was near midnight when we reached the last active camp but one on the line, where we alighted. It was wiser, I was told, to run the remaining length of the track by daylight. Here a doctor and a few engineers, bearing handlamps against which moths were blundering, met us in a place which seemed to be the bottom of a well, for the black shadows which rose round us shut out all but a few stars. The men raised joyous cries at the sight of Hill; and they took this stranger on trust. We fed in a hut which was four poles and a roof. One pole had a hurricane lamp tied to it. There was an enormous quiet, which the men seemed to delight in breaking with their voices. Four planks nailed unevenly to uprights was our table, and we sat crooked on a similar but lower construction. We ate out of enamelled plates with iron instruments, and it was very good indeed. There were four of us who were white, and we were babes in the wood. One of us pretended he was playing on a Jew’s-harp, sang songs riotously, and then began to talk long and earnestly of New York. These men lived in four railway waggons which had doors made of copper gauze, berths with mosquito bars, and portraits of the folk at home; and in the case of the doctor the waggon smelt of iodoform, had one wall full of bottles, and a table with a board and chessmen. In one of those waggons I lay down to sleep under a net; but the blanket felt damp and had a foreign smell. My thoughts crowded me. For long I listened to so much jungle pressing close to my bed, waiting for it to make known its near but unseen presence with a voice; but it did not.
Next morning at sunrise the train moved forward to the construction camp at the Rio Caracoles. I rode on a truck pushed in front of the locomotive, perched there with some engineers who kept a careful eye on the track. I saw at once why the train did not proceed at night. It was too speculative altogether. Behind us the locomotive’s smoke stack rolled like a steamer’s funnel when a beam sea is running. This part of the line crossed many ravines, where we looked down upon the tree tops; and when on a frail wooden bridge which crossed a vacancy like that such movements of the drunken engine behind us became dazzling. Then, too, there were some high “fills,” or embankments. After heavy rains these have a habit of retiring from the metals, which are left looped and twisted in mid-air. An engineer told me that one cannot always tell when an embankment is on the point of retiring. He was carefully watching, however. But we reached the construction camp.
At the construction camp by the side of the Rio Caracoles we stayed two days. There was the end of the line, and the men who were growing the track were so busy that I was left to my own devices. Till the railwaymen came none but the Caripuna Indians knew what was there; so into the woods, of course, I would go, trying every track which led from the camp. A botanist might have seen some difference from the forest at Porto Velho, but I could not discover any. In appearance it was exactly the same. The trees mostly were arborescent laurels I believe, with smooth brown boles which were blotched through their outer cuticle peeling away, much in the manner of that of the plane tree. The brown parchments of their laurel-like leaves covered the floor of the woods. The trees were rarely of great diameter, but their crowns were so distant that nothing could be made of their living foliage. I saw no flowers at all. There were few orchids, but the large shapely emerald coloured leaves of pothos plants were very frequent, sitting in the angles of branches and trunk. Aloft was always the wreckage of vines suspended, as vaguely seen and as motionless as cobwebs and dilapidations in the overhead darkness of high vaults. I rarely heard a sound in that forest, though there was a bird which called. I often heard it in the woods of the upper Madeira. It called thrice, as a boy who whistles shrilly through his fingers; a long call, and then another whistle in the same key followed instantly by a falling note. One delightful walk was along a path which had not been made by the railwaymen, for it was evidently old, as it ran, a cleft in the trees, not through broken timber, but in partial sunshine, with a mesh of vines and freely growing plants on either side. It led downwards to a small stream, which was cumbered with fallen and rotting timber, a cool hollow where ferns were abundant. It was in the woods at the Caracoles that I first saw the great morpho butterfly at home. This species, peculiar to South America, is rarely seen except in the shades of the virgin forest. One day in the twilight aisles near the Caracoles camp, where nothing moved, and all was a grey monotone, it so surprised me with its happy undulating flight—as though it danced along, and were in no hurry—its great size, and its bright blue wings, that I rose mesmerised, stumbling after it through the dank litter, thoughtless of direction, not thinking of the danger of losing my way, thinking of nothing but that joyous resplendent creature dancing aloft ahead of me in the gloom and just beyond my reach. Its polished blue wings flashed like speculæ. It might have been a drifting fragment of sunny sky. I had never seen anything alive so beautiful. A fall over a log brought me to sobriety, and when I looked up it was gone. Afterwards I saw many of them; sometimes when walking the forest there would be morphos always in sight.
The construction camp was not more than a month old. Perched on an escarpment by the line was a row of tents, and at the back of the tents some flimsy huts built of forest stuff. They stood about a ruin of felled trees, with a midden and its butterflies in the midst. Probably thirty white men were stationed there. They were then throwing a wooden bridge across the Caracoles. Most of them were young American civil engineers, though some were English; and when I found one of them—and he happened to be a countryman of mine—balancing himself on a narrow beam high over a swift current, and, regardless of the air heavy with vapour and the torrid sun, directing the disposal of awkward weights with a concentration and keenness which made me recall with regret the way I do things at times, I saw his profession with a new regard. I noticed the men of that transient little settlement in the wilds were in constant high spirits. They betrayed nothing of the gravity of their undertaking. They might have been boys employed at some elaborate jest. But it seemed to me to be a pose of heartiness. They repelled reality with a laugh and a hand clapped to your shoulder. At our mess table, over the dishes of toucan and parrot supplied by the camp hunters, they rallied each other boisterously. There was a touch of defiance in the way they referred to the sickness and the shadow; for it was notorious that changes were frequent in their little garrison. They were forced to talk of these changes, and this was the way they chose to do it. As if laughter was their only prophylactic! But such laughter, to a visitor who did not have to wait till fever took him, but could go when he liked, could be answered only with a friendly smile. Some of my cheery friends of the Caracoles were but the ghosts of men.
