ONE of the main drawbacks of travelling at these great altitudes was the want of vegetable fuel. There was not a tree, not a shrub to be seen near our camp. Nature wore her most desolate and barren look. Failing wood, my men dispersed to collect and bring in the dry dung of yak, pony and sheep to serve as fuel. Kindling this was no easy matter, box after box of matches was quickly used, and our collective lung power severely drawn upon in fanning the unwilling sparks into a flame only a few inches high. Upon this meagre fire we attempted to cook our food and boil our water (a trying process at such an altitude), keeping our own circulation fairly normal by constantly required efforts. The cuisine that night was not of the usual excellence, and did but little credit to the cook. We had to eat everything half-cooked, or, to be accurate, almost altogether uncooked. The night was a bitterly cold one, with a heavy fall of snow. When we rose in the morning it lay quite two feet deep around us, and the glare was painful to the eyes. I mustered my men. Mansing was missing. He had not arrived the previous night, and there was no sign of the man I had sent in search of him. I was anxious not only from my personal interest in his load (the fellow carried a load of flour, salt, pepper, and five pounds of butter), but I was afraid that the poor leper might himself have been washed away in one of the dangerous streams. Even if this fear were groundless, he must, I felt, have suffered terribly from the cold with no shelter and no fire. Bijesing, who had gone in search of him, had eaten some food before starting, and had taken blankets with him in case he could not return to camp during the night. It was long after sunrise when, with the aid of my telescope, I discovered the two men coming towards us. They arrived an hour or so later. Mansing had been found sound asleep, several miles back, lying by the side of the empty butter-pot, the contents of which he had devoured. The discovery of this misdeed caused the greatest indignation in camp, for fatty matter and butter were much cherished by the natives, as being warmth-producing, when going over these cold passes. He was nearly the victim of summary justice at the hands of my angry men, and it was only with trouble that I rescued him from their clutches. To prevent a recurrence of the offence, I ordered the culprit to carry in future a heavy load of photographic plates and instruments, which I thought would not prove quite so appetising. Before starting I took my usual bath in the cold stream and rubbed myself all over with snow. I found this very invigorating, and when the reaction came I experienced a delightful glow of warmth, notwithstanding the thin clothes I was wearing. [Illustration: CAMPING IN SNOW]
