of it. Pan. 186, Tab. 34, is taken from the second threshold and represents the landscape to the south. Pan. 189A and B, Tab. 34, is a view from Camp CL VI, giving a good perspective of the range we had just crossed in the Angden-la, probably the same in which the Sha-la is situated. To the N. 47° E. is Mount Ira with Ire-lung-pa from where the Kyam-chu comes down. To the E. S. E. are the mountains Tambe and Kintang. To the south is the Amchok-tang, or plain surrounded with its mountains.

The plain of Amchok falls very gradually to the south, and our next march, on May 7th, to the S. S. W. on this plain, descends only 84 m. or to 4,870 m. at Camp CL VII, at Hramsang, on the N. W. corner of Amchok-tso. The rate is 1: 205. Pan. 188, Tab. 34, is taken from Amchok Yung a few kilometers north of Hramsang. It is of importance as showing how very difficult it is to solve the orographical problems of the Transhijnalaya with the material I was able to bring home. Nobody should wonder at this fact. I have only crossed the system on a few lines. Even the Himalaya which has been so thoroughly explored, mapped and measured, is orographically not quite known. On the panorama in question we have a range to the north and N. 200 E., certainly the one of Angden-la to the north of Amchoktang. N. 30° E. is Do-tsänkang- from this side also cropping up as a solitary peak. The Kintang, N. 70° E., seems to belong to a special range, situated south of the one with Sha-la. In front, or south, of it is another range, which S. 76° E. has a first snow-covered pyramidal peak, and to the S. 57° E., S. 48° E., S. 36° E. and S. 3o° E. a series of other, very considerable peaks. The question is whether this range may represent the western end of the Nien -chen -tang- la, but this problem can only be solved by detailed exploration on the spot.

Pan. 193A and B, Tab. 35, from Camp CL VII, Hramsang, gives another aspect of the surrounding mountains. To the west and N. W. are the mountains Puchu and Ngingri, to the north the range of Angden-la, to the east is the northern-most part of Amchok-tso, and to the E. S. E. and S. E. Mount Shakokshar, probably a part of the same range which I supposed to be the western continuation of

Nien-chen-tang.-la. The mountains visible to the S. S. E. are situated between the Raga-tsang po and the great Tsangpo. Finally Pan. 191, Tab. 35, is a little view to the S. E. from the southern shore of Amchok-iso, and Pan. 194, Tab. 35, a view to the N. W. and north, across the lake from the same point.

On May 1 oth, we travelled 9 km. to the west and south, rising 440 m. to Camp CL VIII, Serme-lartsa, which is at 5,310 m. The rate is 1: 20.4.

The next day's march, on May 11th, we had 5.3 km. S. S. W. to the pass of Sao-lungring, 5,387 m, high, or 77 m. above the last camp, the rate being I:68.9. Then follow 9 km. sinking and again rising ground to a second, nameless, pass with an altitude of 5,384 m. From this secondary threshold we had only 3.2 km.
