We stopped two days longer at the Paso del Medio, and then, tormented with continual restlessness, we moved thirty miles further up, to the last pass, called the 'Paso de Alquinta.'

We camped at about six miles from the pass itself, under shelter of what Isidoro, rather grandiloquently, persisted in calling a 'house,' but which was in reality nothing but three low walls, barely four feet high, built by some Indian traders of blocks of lava, the chinks between which were stopped with mud and grass.

The 'house' was, of course, roofless, and by no means so good a lodging as a thick bush would have been; but still it was better than nothing, and at all events enabled us to have always a good fire burning without consuming too much fuel—a very important consideration, as there was very little wood to be met with anywhere in that region.

During the first night there was a heavy fall of snow, and on waking I felt an unusual weight on my furs, and under them an excessive warmth I was certainly not accustomed to.

Thrusting out my head I found everything covered with snow. The distant hills stood out in glittering relief against the dark grey sky, and the whole landscape was specklessly white, except where the river flowed along the valley, looking inky black by contrast with the surrounding country. Our horses, poor animals, plentifully besprinkled with snow, too, were standing near to the camp, herded motionless together, with sadly drooping heads, and an expression of patient suffering and forlorn misery in their rough faces, which filled me with compassion for them.

We remained in bed till the afternoon, when the snow began to thaw away, soaking all our bedding and making things generally uncomfortable for us.

Fearing the effect the melting of the recent snow might have on the river, we resolved to make an attempt to cross it the following morning. Isidoro, to whom we now communicated our intention for the first time, seemed quite alarmed at the idea, and did everything in his power to persuade us to desist from it. Until this occasion, I had never been able to get more than half a dozen words out of him at a time; but now, in his efforts to induce us to give up our undertaking, which he qualified as an act of utter madness, he waxed quite eloquent, and made a longer speech than he had probably ever delivered himself of in his whole existence. The current, he urged, was too strong for our horses to stem; moreover, a companion of his, he told us, had once tried to cross the river when it was not nearly so swollen as now, and had narrowly escaped being drowned. Finding, however, that we had made up our minds, and were not to be persuaded to alter them, Isidoro relapsed into his usual silence, whilst we made our preparations for the ensuing day.

We intended crossing over at sunrise, so as to have ample time to dry our wet things on the other side before night-time. In order to be able to rely on having something dry to cover ourselves with immediately after our swim over, we rolled two capas up as tightly as possible, and stuffed them into a small water-tight canvas bag. In the middle of the capas we carefully placed our greatest treasure—twelve wax matches in a little tortoise-shell box, which we rendered impervious to damp by securely wrapping it in pieces of guanaco hide.

Of matches, I must mention, we had run short, as of everything else, and were compelled to be most economical in the use of the few that still remained to us, to which end the fire was kept burning day and night. We put into our saddle-bags sufficient ostrich meat and puma fat to last us for three days—the time we calculated we should require to reach Sandy Point in. Guillaume intended leaving his dogs with Isidoro, as they would suffer unnecessarily from the fatigue of such a rapid journey.
