We reached the shore of Nganglaring-tso, 7une 241h, the distance down to the lake, N. W., being 3 km., and then westwards i o km. along the shore. The slope down is very steep, for the lake is at an altitude of 4,746 m., or a descent of 373 m. and a rate of r : 8. Camp CCCCXXXVII, Kungna-dumly, is at 4,748 m. A hill near the shore, N. N. W. of Tayep ftarva, has an altitude of 4,938 m. From this hill Pan. 5 3 3 A and B, Tab. i oo, was drawn. It shows from the N. W. to N. N. E. a new perspective of the large island, and to the N. E. and E. N. E. considerable mountains which must be regarded as the northern continuation of the Surla Range. To the east is pointed out the valley of Ka-la. Nearly the same landscape, though in another perspective, is shown on Pan. 535, Tab. i oo.
On 7une 251h, we had to cross a ridge which projects to the southern shore. We had to climb 53o m. in a distance of 7.1 km. to the W. S. W. to the pass Pu-karu-la, where the altitude is 5,278 m.; the rate is, therefore, r : i 3. On the western side we again descended 2 94 m. in 2.8 km. to the S. W. to Pebuk, situated at 4,984 m. Here the slope is as i : 9.5. Pan. 536A, B and c, Tab. I o 1, taken from Pu-karu-la, is of very great interest. It unrolls, namely, considerable portions of all the three high Transhimalayan Ranges Surla, Pedang and Lavar, the snowy crests and peaks of which are visible to the S. E., south and S. W. To the N. 82° W. it shows the course of the Sumdang-tsangj5o just above its entrance in the lake. To the N. W., north and N. N. E. it shows another view of the Nganglaringtso with its islands and promontories. To the N. E. and E. N. E. we again meet a part of the Surla Range.
On 7une 26th, we travelled j1.9 km. W. N. W. to Camp CCCCXXXIX on the Sumdang-tsangj5o, at an altitude of 4,758 m., a descent of 226 m., and a rate of fall as 1:53.
The whole road to Camp CCCCXXXIX, from where the last crossing begins, is thus 398.6 km. in length.
