At an elevation of 4450 feet, and at the very edge of the last patch of dwarfed plants that grew upon the desert-like expanse, we found a small oasis between two scoria hills, bounded on the left by the rugged lava ridge which formed the backbone, as it were, of the long, sweeping spur up which we had come. Here a few stunted shrubs and clumps of tussock grass struggled for life amidst masses of lava and scoria sand. We knew that we would have to leave our horses tethered here for something like thirty-six hours without water, whilst we did the rest of the mountain, and we calculated that, with the aid of the few straggling shrubs and bunches of tussock, there would be just sufficient food to keep the animals from starvation during that time, although we had a kind of secret conviction that the chances were immensely in favour of the latter result. After we had secured our horses in the small oasis, we went out to explore the country ahead. In every position along the steep incline up which we had to make our way we saw nothing but enormous scoria hills, stretching far and wide on every side, and which rose in long, steep ascents to the snow-line of the mountain. In every direction stupendous ridges of black trachytic lava cropped up above the surface, broken, rugged, and sharp, as if they had boiled up during some terrific volcanic convulsion, and then suddenly congealed into the most curious and fantastic shapes. Some of the enormous lava ridges, of a black metallic lustre, flowed down, as it were, from the very summit of the mountain, and stretched for miles in length over the desert below. At an altitude of 5500 feet we came to an enormous deposit of lava raising up the surface of the spur in the form of a large cluster of rocks, and on one side of which there was a sheer descent into a lava-bound ravine of 200 feet. This was a good mile and a half away from where we had left our horses, but as the ascent was gradual we determined to pack the animals with the tent and blankets up to this point, and, after taking them back to the oasis, carry the camp equipage on our own shoulders up to the snow-line, where we had resolved to camp for the night, in order to be able to begin the final ascent to the summit of the great peak at daylight on the morrow. It was late in the day when we had finally carried out this arrangement, and, after packing ourselves with the tent, blankets, and all other necessaries to the extent of about twenty-five pounds each, we set off to climb the long, dreary spur, which mounted steeply upward until it lost itself in the region of eternal snow.
