few kilometers before traversing it. We therefore crossed the plain south of the lake in a straight line. The rise was gradual and comfortable to the foot of the southern hills. A comparatively large erosion furrow from the western mountains was crossed, and later on we followed a dry watercourse from the southern hills. These beds, as well as many others around the lake, carry water at some seasons and very likely the lake bed becomes filled with a very thin sheet of water, which soon evaporates in the autumn. At half an hour's distance from Camp LXXI, . we crossed an old beach-line of the lake. We entered the valley coming from the next pass in front of us. Its gravelly bed was filled with extensive ice-sheets and some running water, from springs. Here Camp LXXII was pitched. Of wild animals, only a few antelopes were seen. Dung of kyangs was common, but no signs of wild yak was to be found. From numerous old fireplaces, one could see that the Tibetans used to pass a night here on their wanderings; At half past ten a. m. the usual S. W. wind began.
Pan. 8o, Tab. 13, shows the view to the north from Camp LXXII. In the foreground are the last slopes of the hills on both sides of the valley from the pass. Above them a part of the lake is visible and north of it, the mountain group bordering the lake basin at that side.
