Once again we climbed sleepily into the saddles at daybreak and began crawling up to the final pass over this third and last great range of the Andes. The first night’s camp was hardly below the snow line in a little sheltered cove on the mountain flank; the next morning a slippery climb in a blizzard that coated every mule in ice as though with armor brought us to a ragged, narrow cleft in a long fin of rock through which we passed as through a gateway. It was the summit of the pass. There was on the farther side the usual votive cairn of stones built by the Aymarás with the twig cross at its apex while, leaning against the fin of protruding rock as far as the eyes could penetrate the blizzard, were narrow, spear-head pieces of shale placed on end as further efforts in worship or propitiation of the great god of the mountain.

From the pass the trail dropped a trifle and we crowded for that night into the tambo in Yngenio. They were a surly lot and viewing with a hostile suspicion—doubtless with causes inherited from the remote past of the conquistadores—any outfit of wayfarers.

Again followed a day of sleet and snow-squall with an occasional rift in the clouds when, thousands of feet below, could be seen the soft greens and the waving palms of inviting tropical warmth and dryness. The narrow trail zigzagged up the bare mountain steeps, followed for a distance the wanderings of the crest, and then dropped in another series of zigzags to lower levels. For hours there was this constant rise and fall. In a cold rain we camped in a stone hut, Tolopampa, a place that has the reputation of perpetual mud and rain where the skull of some deserted Aymará packer still kicked around in the cold mud outside.

And then at daybreak began the drop into the warmer zones where there was sunlight and a riot of tropical color. For two days it was one unbroken descent while the back grew weary and exhausted leaning against the cantle and the stirrups interfered with the mule’s waggling ears. The clayey mud of the wallowing trails rose up and wrapped us in its welcome until boot-lacings, spur and puttee buckles blended in shapeless, indistinguishable masses. And then, five days after leaving Sorata, we plodded into the straggling line of palm thatched huts that is credited on Bolivian maps with being the town of Mapiri. For two days the mules were rested while the arrieros passed the time in keeping mildly drunk. Below the high bank on which the town stood, the River Mapiri boiled past in muddy eddies; here in a cane hut we camped and oiled and packed the saddles; from now on it would be rafts, callapos, until we again reached the main camp.

In Mapiri the callapos were waiting and we embarked. One camp on a sand bar, one camp in Guanai and the next day we shot more rapids and came into the country of the truculent one with the long barreled Colt. The barraca lay just around the bend where the river broke in some small rapids and then saved itself in miles of smoothly coiling eddies for the grand smother of the Ratama. It was here at this chief barraca of his company that there might be trouble—we had been warned that if we attempted to round this bend in any unapproved, uncensored callapos we would be fired on. The four Mausers had been issued and the case of ammunition unscrewed. There were four callapos with the white men on the one in the lead. It was rather exciting, this uncertainty, but it was accompanied by the invariably clammy spinal undulations and the strong desire that I was somewhere else or that what that jungled river bed held for us was an incident of the past rather than of this imminence.

As though casually the freight had been loaded on the callapo platforms so that it made an informal breastwork and quite as informally we loafed behind it. And then the callapos drifted silently around the bend—we had not fired the salute that is ordinarily made when approaching a barraca at which one is going to stop and call—and the clearing with its collections of huts and palm thatched roofs broke into view. A little figure scuttled across the clearing and disappeared. The edge of the clearing on the bank was within a stone’s throw and not a sound broke the stillness. A word to the Leccos and their heavy paddles began working us over to the bank where a little path ran down to the water’s edge. If the two camps were in for a frontier war, a feud, it might as well be found out at once. Before there had been only the threats of a foolish man—here was the place and here were the men under his control. How far would they back his stupidities?

In single file we climbed the steep path to the clearing; at the top the head man came forward cordially.

“What’s this about firing on us as we came around the bend—you getting in Winchesters by the crate?”

He laughed cheerfully:

“Oh, phut! If it amuses that old fool outside to send them in I don’t mind, but if he wants to start any fighting let him come on in and do it himself.”
