"Unfortunately, one of the last three Indians sent back had in his pocket all the chocolate, an article almost indispensable to the comfort of a party climbing a high mountain, and, unconscious of our loss, we continued our way until it was too late to remedy this loss. The basaltic rock which we had now reached was covered with the icicles which I have described, and we found no little difficulty in placing our feet between them, and guiding ourselves with the iron-pointed sticks which had been furnished us; while the dizziness caused by looking back upon the world we had left behind added to our troubles. "Mr. Corchado, to draw off our attention from our own hardships, related to us the story of the death of six of his workmen, who undertook to make the journey down the mountain by night. Each of them had a load of stolen brimstone on his head. The day after this rash and criminal attempt, their dead bodies were found in such a situation as to indicate plainly the manner of their death. Stiffened with the intense cold, and impeded by their heavy burdens, they had stumbled in the darkness, and had fallen upon the sharp ice. One had his cheek pierced, and the others had divers wounds and bruises marked upon them as they lay frozen in death. The story of these unfortunates was not calculated to inspire us with very pleasant reflections, in case the weather should change while we were on the mountain. A NIGHT UPON THE SUMMIT. "We climbed on, having reached the basaltic rock at an elevation of 16,805 feet, and with exhausting labor we traveled upon it until toward evening, when we came to that immense yawning abyss, the crater. The mouth was about three miles in circumference, of a very irregular form. Into this we entered, and soon arrived at the house which was to be our lodging for the night. This house was a curiosity in its way; as it was not built like any other house, and could not be, on account of the rarity of the atmosphere at this elevation of 17,125 feet, and the impossibility of obtaining sufficient oxygen, in a closed room, to feed combustion. It was therefore built in the form of a miniature volcano. There was an outside and an inside wall, of a circular form, the outside wall sloping inwardly, and the inside wall, which rested on pillars, sloping outwardly, until it met the outside wall. The fire was built in the open court, in the centre of the building, and the party sat under the arches and warmed themselves. The night that we were there, the perverse smoke took the same direction as the heated air, and filled the whole inside to suffocation, so that our condition was most disagreeable, notwithstanding the arrangements that Mr. Corchado had made in his own apartment for the comfort of his guests, for the reflection of the sun on the snow had thrown a film over our eyes, in spite of our green vails. Our stomachs were nauseated at this giddy height, and, though we had almost every other kind of eatable and
