THE SOURCE OF THE 1RAHMAFUT .A.   363

Dongdong, Chema yundung j5u and Chetea, which is a mountainous region north of Chema yundung -u. From Camp CC some of the same mountains were drawn when covered with clouds, as shown on Pan. 260, Tab. 48. Here a new name, Mukchung-limo, makes its appearance.

On 7uly 12111, we travelled S. W. 17.6 km. to Camp CCI at Shaaka, where the altitude is 4,841 m., or 20 m. lower than Hlayak which is situated on the slope of the left side of the Kubi-lsangto. From Shajka, Pan. 259, Tab. 47, is taken. It shows the valley of the Kubi-tsangpo to the N. E., and to the east and E. S. E. the northern ramifications from the Kubi gangri. The little peak to the S. 52° E. is the same as the peak farthest to the left on Pan. 261, Tab. 48, which is in immediate connection with Pan. 259, though the continuity has been interrupted in the Atlas of Panoramas. On Pan. 261 it is easy to recognize the peaks we already know from the view from Tso-niti-kargang-, though now the perspective and the angles have changed.

The next day we made an excursion 8.8 km. west to the snout of the two glaciers which I have called Langta-c11en (from one of the peaks in its upper reaches) and Brahma z tra Glacier, as it is the highest feeder of the Kubi-tsangpo which is the main source of the Bralzrnaj5utra. The two glaciers join and have a common snout. In front of this is a moraine on the slope of which Pan. 256, Tab. 47, was sketched, showing again the imposing perspective of the ring of high peaks surrounding to the south the sources of the Kubi-/sang to, and all together called Kubi-

gangri.

On 7uly 14111, we climbed the moraine heaps and hills west of Camp CCI 3.7 km. to a point 5,310 m. high. The rise is 469 m. and the rate 1:7.9. From this point I sketched the complete panorama 262A and B, Tab. 48, which gives a new aspect to the peaks of the Kubi gangri. This panorama took some three hours to draw. Immediately after it was completed I made a panorama in a series of photographic plates connected uninterruptedly with one another. It is to be found opposite p. 262 of Vol. II, and should be carefully compared with the pencil-drawing as such a comparison gives an idea of the degree of exactitude at which I was able to arrive in the panorama-sketching. These two panoramas have been scientifically compared and discussed by Professor Karl D. P. Rosén in Ymer, 1918, as quoted above.

From the point 5,310 m. high., we had 10.2 km. N. E. to Camp CCII, Dong-dong, 4,844 m. high, a fall of 466 m. and a rate of 1 : 2 2.

On 7uly 15th, we continued N. E. The first 9.6 km. took us to Kargang-la 5,182 m. high, a rise of 338 m. and a rate of 1 :28. From the pass we had 4.8 km. to Camp CCIII, Dara-sumkor, 4,931 m. high, a descent of 251 m. and a rate of 1:19. Pan. 2 66A and B, Tab. 49, was drawn from Kargang-la. It shows the Dong- dong Jru and C1zema yundung Ju both snow-mountains with glaciers contributing to
