On April 8M, our road takes us up the valley of Mü-chu 14.3 km. N. N. W. to the village and monastery of Tong, Camp CXXXVIII, where the altitude is 4,167 m. The latter figure is rather misleading as the camp was situated at a considerable height above the bed of the river. However, the rise from Camp CXXXVII amounts to 97 m., and the rate is 1: 147. The panorama, 160A and B, Tab. 29, from Tong, is again instructive, and gives the impression of narrow, deep-cut valleys. To the S. 16° E. the view opens through the valley of Tong with the river Mü-chu by which we have arrived. In the distance a part of Mount IL abu-kidang- is visible. This part of the panorama should be compared with the third photograph opposite p. 2 70 in Vol. III, which gives an idea of the degree of correctness at which I have been able to arrive, and which has been scientifically examined by Professor Karl D. P. Rosén.' To the S. W. and west is the bulky mountain mass of Takbo-che, and N. 62° W. the group Va-munya to the left of which the little tributary valley of Tina comes out, and to the right of which the Mü-chu valley continues to the north to the water-parting of the Transhimalaya. To the N. N. W. and N. N. E. is the monastery of Tong with its several buildings, and to the N. 80° E. the tributary valley of Tong juchen. On its southern side a part of the ridge Tovakü is also visible with one of the characteristic houses at its base.
On April IoM, we travelled 9 km. north to Camp CXXXIX, Ge, or Ghe, which is the name of a tributary valley entering here from the east. The altitude at Ge is 4,204 m. which is also misleading as the camp, again, is situated at a considerable height above the bed of the Mü-chu.2 The difference in height, from Tong, is 37 m. and the rate of ascent, along the road as I :243.
On April i ith we had i6 km nearly north to Camp CXL or Sirchung, where the altitude is only 4,177 m. or 27 m. lower than Camp CXXXIX, meaning a slope of 1 : 593. This is due to the fact that the latter camp is situated on a terrace at a considerable height above the main river, whereas the camp of Sirchung is in the bottom of the valley. As a matter of fact the fall of the Mü-chu is somewhat steeper on this section of its course, as could be seen from the more common rapids.
From Sirchung Pan. 1 5 6A and B, Tab. 28, was drawn. From the east the Gelung valley enters, and to the S. 55° E. on the eastern side of the river, Gompa-son is visible. Below and in front of the peaks S. 31° E. and S. i2° E. the Mü-chu valley is seen by which we have ascended. To the N. 24° W., just to the right of a few houses of the village Sirchung, the valley of the Mü-chu continues in the direction of the great Transhimalayan water-parting. Nearly due north is the monastery of Lelung-gompa, which I have described elsewhere.
