Carrying the traps I had manufactured, and my fishing-line, I now sallied out. I had exhausted all my roots, but as the snow cleared away I obtained a further supply, though, hungry as I was, I still had very little inclination to eat them raw. I had not gone far when I came to some boiling springs; one of which, although the water was of intense heat, was little larger than a good-sized caldron. I threw in my roots, and sat down beside it to warm my feet, which were benumbed with the melting snow. While my frugal dinner was cooking, I looked about in search of my friends; but again I was disappointed. When I thought that the roots were sufficiently boiled, I raked them out with my stick. They were certainly more palatable, and I hoped they would prove more nutritious. Every hour was now of importance, for Manley and the sergeant would, I calculated, be pushing on, under the belief that I was before them. I had quenched my thirst with snow, for in that volcanic region I could find no water fit to drink; it was either intensely hot, or so impregnated with sulphur and other minerals that I was afraid to swallow it. I saw that it would soon be necessary again to camp, so, that I might not have to pass the night without a fire, I endeavoured to obtain a light by means of my burning-glass, before the sun should descend too low. The wood around was so wet that I feared, after all, I should not succeed; but having made my way to a forest on one side of the valley, I discovered some moss growing under the branches of a tree which had sheltered it from the wet. Here also was abundance of dead wood. With as much as I could carry I hurried back into the open, and sitting down, brought the glass to bear on the now fast sinking rays of the sun. I watched the effect with almost trembling eagerness, till, greatly to my joy, from the small bright spot caused by the concentrated rays a thin thread of smoke began to ascend and spread over the moss. This I blew gently, placing over it a few twigs at a time, until I soon had a brisk fire burning. The place where I had lighted my fire was not one at which I wished to camp, but once having a fire, I could carry a burning brand and ignite another in some more convenient situation. I was not long in selecting a spot close under a rock, where I soon had a fire blazing up. I thus had warmth, although I was still destitute of wholesome food; and, indeed, I found myself weaker than I had ever before been.
