There are two sources of the Kuti Yangti, joining in a large basin; one comes from two extensive glaciers to the S.W., the other from a glacier directly under the Lumpiya Pass. The river at the junction of the two sources is not more than six yards across. Our route gradually ascended, going N.W. first, then swinging away to N.E. until we attained an elevation of 17,350 feet on a flat basin covered with deep snow. So far we had proceeded with no very great trouble or fatigue, but matters suddenly altered for the worse. Each coolie in the long silent row at the head of which I marched, sank in the snow up to his knees, often up to his waist. They formed, undoubtedly, a picturesque sight in this lonely region, the only bit of life in the picture, the white frozen sheet of snow throwing into strong contrast their faces wrapped tightly round with white turbans. Some wore fur caps with ear flaps; all had long sheepskin coats and high boots of skins; many used snow spectacles; and as this procession, silent and grave, with loads on their backs, struggled higher and higher with piteous panting, you speculated apprehensively as to how many of them would ever return. Moving cautiously to avoid the many treacherous cracks, I made my way ahead with considerable trouble to a spot six hundred feet higher, where I halted for a while on a rocky island fairly clear of snow. As coolie after coolie arrived, breathing convulsively, he dropped his load and sat quietly by the side of it. There was not a grumble, not a word of reproach for the hard work they were made to endure. Sleet was falling, and the wet and cold increased the discomfort. There was now a very steep pull before us. To the left, we had a glacier beginning in a precipitous fall of ice, about one hundred feet in height. Like the Mangshan glacier, it was in horizontal ribbon-like strata of beautifully clear ice, showing no dirt bands. Perpendicular stripes of a darker greenish colour could be observed arising from the unequal degrees of compactness of the ice; the strata showed almost horizontal, with no curvatures nor depressions in any part of them. The top, the base and the sides of the glacier were in this case also buried in deep snow. The doctor and I went ahead. In our anxiety to reach the summit, unable to discern the track, now covered by several feet of snow, we mistook our bearings, and with great fatigue climbed up an extremely steep incline. Here we were on a patch of the troublesome loose _debris_, on which we struggled for over half an hour until we reached the top of the range, 18,750 feet, considerably higher than the pass itself. Four men had come with us, the others, to whom we signalled, bearing more to the west by another dangerous track skirting the glacier.
