Twice during the day we met a train of heavy, crude ox-carts roofed with sun-dried ox-hides, that recalled the “prairie-schooners” of pioneer days, eight oxen to each, creaking westward with infinite slowness. In the afternoon the forest closed in about us, and we plodded on through deep sand alternating with mud-holes. Soon all the woods about us were screaming like a dozen suffragette meetings in full session and, fancying the uproar came from edible wild fowls, I crept in upon them, rifle in hand. To my astonishment, I found a band of small monkeys shrieking together in a huge tree-top. Even a monkey steak would not have been unacceptable. I fired into the branches. Instantly there fell, not the wherewithal for a sumptuous evening repast, but the most absolute silence. The little creatures did not flee, however, but each sprang a limb or two higher and watched my slightest movement with brilliant, roving eyes. A qualm came upon me and I hurried after the German.

That night we camped in a clump of trees about a water-hole. The native who pointed out the trail to it did so in a surly, regretful manner, as if he resented the consumption by strangers who should have remained in their own country of a priceless treasure insufficient for home consumption. Down at the bottom of a deep hole in the sand, strongly fenced with split rails, was an irregular puddle barely four inches deep, full of fallen leaves, wrigglers, and decayed vegetable matter; yet from it radiated trails in all directions. The blocks of crude brown sugar we had purchased that morning had melted during the day and smeared everything within reach; the boiled leg of mutton already whispered its condition to the nostrils. The breeze a slight knoll promised treacherously died down, and the swarms of insects that sung about us all night frequently struck home, in spite of the close-knit mosquitero that kept us running with sweat until near dawn.

Monkeys were already howling in the nearby woods when we pulled on our clothes, wet and sticky, in a soggy morning that soon carried out its promise of rain; and parrots now and then screamed at us in dull-weather mood. A heavy shower paused for a new start and became a true jungle deluge. My poncho would have been useless; besides, it was wrapped, in Australian “swag” style, around my possessions on the mule. Past experience told me that the only reliable waterproof in the tropics is to let it rain—and dry out again when opportunity offers. We settled down to splash on indifferently, soaked through and through from hat to shoes, dripping at every seam. The weather was not over warm either, and only the heaviest moments of the storm dispersed the swarms of ravenous mosquitoes.

In dense woods punctuated with mud-holes, a yellow youth in two cotton garments overtook us well on in the afternoon, and asked if we would need a “pelota.” We would. He stopped at a jungle hut some distance beyond and emerged with an entire ox-hide, sun-dried and still covered with the long red hair of its original owner, folded in four like a sheet of writing paper, on his head. For a mile or more he plodded noiselessly behind us. Then suddenly the forest opened out upon the notorious Guapay, or Rio Grande, a yellow-brown stream, wide as the lower Connecticut, flowing swiftly northward to join the Mamoré on its journey to the Amazon. We splashed a mile or more up along its edge, to offset the distance we should be carried downstream before striking a landing opposite. Here two men of bleached-brown skin, each completely naked but for a palm-leaf hat securely tied on, relieved our companion of his load and set about turning it into a boat. These “pelotas de cuero” (“leather balls”) are the ferries of all this region, being transportable, whereas a wooden boat, left behind, would be stolen by the “indios bravos.” Around the edge of the hide were a dozen loopholes through which was threaded a cord that drew it up into the form of a rude tub. To add firmness to this, the hat-wearers laid a corduroy of green poles in the bottom. Then they piled our baggage into it, set the German atop, and dragged it down the sloping mud bank into the water, while the youth coaxed the mule into the stream and swam with it for the opposite shore. This seemed load enough and to spare. But when I had fulfilled my duties as official photographer of the expedition, I, too, was lifted in, as they would no doubt have piled in Tommy also, had he been with us, and away we went, easily 500 pounds, speeding down the racing yellow stream, the naked ferrymen first wading, then swimming beside us, clutching the pelota, the “gunwales” of which were in places by no means an inch above the water. Had the none-too-stout cord broken, the hide would instantly have flattened out and left us—for an all-too-brief moment—like passengers on the magic carpet of oriental fairy-tales.

Before and high above us, where the peloteros coaxed the crazy craft ashore, stretching like a Chinese wall of vegetation further than the eye could follow in either direction, stood an impenetrable forest, the famous Monte Grande, or “Great Wilderness,” of Bolivia. Here was the chief haunt of the wild Indians of the penetrating arrow, a region otherwise uninhabited, through which the “road” to the Paraguay squeezes its way for hundreds of miles almost without a shift of direction. We swung our hammocks on the extreme edge of the river, where the breeze promised to blow—and failed of its promise, like most things Latin-American. For though the day was not yet spent, the journey through the Monte Grande is fixed in its itinerary by the four “garrisons” maintained some five leagues apart by the Bolivian government as a theoretical protection against the nomadic Indians. At dusk a man swam the river with his clothing and possessions in the brim of his hat, and soon afterward the stream began to rise so rapidly that it is doubtful if we could have passed it for several days.

Almost at once, in the morning, we met a train of nine enormous roofed carts of merchandise from Europe by way of Montevideo, each drawn by eight yoke of gaunt, way-worn oxen, straining hub-deep through the mire at a turtle’s pace. The forest crowded them so closely on either hand that we must back into it, as into the shallow niche of an Inca wall, and stand erect and motionless until the train had crawled by, the wilderness bawling and echoing a half-hour with the cries of the dozen drivers with their long goads dodging in and out, knee-deep in mud, among the panting brutes. We met no other person during the day. Travelers through the Monte Grande go always in bands, and the ox-drivers stared at us setting out alone, as at gringo madmen.

We deployed in campaign formation. Our revolvers loose in their holsters, the German marched ahead, closely followed by his affectionate “mool,” while I brought up the rear with his new Winchester. Mine was the post of honor and most promise, for the Indians of the Monte Grande do not face their intended victims, but spring from behind a tree to shoot the traveler in the back, and dodge back out of sight again. They shoot seated, using the feet to stretch the bow, a slight advantage, in point of time, to their prey. Rumor has it that the tribe is by nature peaceful; but they were long hunted for sport and are still shot on sight, with no questions asked, and so have come to look upon all travelers as tribal enemies. They are said to be entirely nomadic, to wear nothing but a feather clout, and to bind their limbs in childhood, so that the forearm and the leg below the knee become mere bone and sinew with which they can thrust their way through the spiny undergrowth without pain. This improvement on nature draws the foot out of shape, and the footprint of a savage, showing only the imprint of the heel, the outer edge of the foot, and the crooked big toe, is easily distinguished from that of the ordinary native. However, that was not my lucky day, and I caught not so much as a kodak-shot at a feather clout, though I glanced frequently over my shoulder all the day through.

But if the Indians failed us, there were other visitations to make up for them. Every instant of the day we fought swarms of gnats and mosquitos; though the sun rarely got a peep in upon us, its damp, heavy heat kept us half-blinded with the salt sweat in our eyes. The road was really a long tunnel through unbroken forest meeting overhead, into which the thorny undergrowth crowded in spite of the ox-cart traffic. All day long, mud-holes, often waist-deep for long distances, completely occupied the narrow forest lane. The region being utterly flat, the waters of the rainy season gather in the slightest depression, which passing ox-carts plough into a slough beyond description; while the barest suggestion of a stream inundates to a swamp all the surrounding territory. For the first mile we sought, in our inexperience, to tear our way around these through the edge of the forest. But so dense was this that it barred us as effectually as a cactus hedge. We took to wading, now to the knees, now to the waist, sometimes slipping into unseen cart-ruts and plunging to the shoulders in noisome slime.
