"A labyrinth of rocks brought us out in front of a stony rampart, more than a hundred feet in height."
We did justice to our game like guests who have to make up for a forced fast. The meal finished, without further delay our little coterie moved on again. Instead of the abundant and bushy thickets of sarsaparilla, we met with nothing but stunted shrubs. However, as we approached the mountain the vegetation assumed a richer aspect, and the bare rocks no longer protruded through the soil. Here and there, tanagers, with black backs, yellow breasts, and violet-blue throats, fluttered around us; also other variegated birds of the Passerine family. We were just about to begin climbing the slope, when l'Encuerado, whose piercing eyes seemed to see every thing, exclaimed:
"There are some potatoes!"
Lucien ran towards the Indian, who, with his machete, had already cleared away the earth round a small plant with oval-shaped leaves, covered with soft greenish berries. Some wrinkled tubercles were ere long discovered, which we could easily crush between our fingers. This is the origin of the valuable plant for which Europe is indebted to America.
After climbing some time, we came upon a mass of rocks all heaped up in a perfect chaos. Some obstacle or other incessantly obliged us either to jump over or make a circuit so as to get forward. The temperature, however, was refreshing, and rendered our exertions less fatiguing.
The chances of our journey brought us out once more upon the plateau. All the mountain crests we could see were barren, and a profound silence reigned on every side. We stopped to take breath, and the sight that met our eyes impressed us with its stern grandeur. It reminded Sumichrast of the Swiss mountains which he had so often traversed; and some flowers he gathered further recalled his home. While thus occupied, two butterflies fluttered over our heads.
"It is an Alpine species!" eagerly cried my friend.
The locality prevented him from following these capricious insects for any distance: for one moment he leaned over the abyss, bristling up with rocks, and followed, with a longing eye, the two winged flowers which had recalled to him a fleeting image of his fatherland.
A labyrinth of rocks brought us out in front of a stony rampart more than a hundred feet in height, and almost perpendicular. This unexpected obstacle brought us to a halt. How should we make our way over it? Upon examining the spot, we decided to incline towards the left, which seemed to us the most accessible road. In parts the wall diminished in height, but we tried in vain to climb it. A more successful attempt, however, brought us nearly to the top, but not without great fatigue, for sometimes the rock appeared to hang over us. At length, by climbing on to Sumichrast's shoulders, I managed to reach the flat surface above. I hoisted up Lucien here with the lasso; next I drew up Gringalet, who was only too pleased to submit to the operation, and lastly Sumichrast and l'Encuerado. The terrible obstacle was at last overcome; beyond it the ground was, comparatively speaking, level, but covered with stones of a volcanic nature.
We still kept on our way, although it was four o'clock, in the hope of finding some tree at the foot of which we could make our bivouac. L'Encuerado put down his load to climb up a needle-shaped rock, the extraordinary position of which reminded us of the celebrated leaning tower of Pisa. When he had reached its top, the Indian called out to us that he could see a clump of trees. The cold began to inconvenience us and we wanted wood to make our fire, so, plucking up fresh courage, we continued our journey. The distance now traversed was inconsiderable; but the ups and downs and circuits had quite wearied us. Gradually the rocks decreased in size, and were more widely spread; a plain slightly depressed in the centre, dotted here and there with thinly growing thickets, was reached. In the background there was a clump of firs and a glittering lake, quite a liquid oasis hidden in a desert.
