On *April 8th,* 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 conside-
rable 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 *Kabu-kidang* is visible.
This part of the panorama should be compared with the third photograph opposite
p. 270 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.¹ To the S. W. and west is the bulky mountain mass of *Takbo-che,*
and N. 62° W. the group *Ya-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-puchen.* On its southern side a part of the ridge *Tovakü* is also
visible with one of the characteristic houses at its base.

On *April 10th,* 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 1:243.

On *April 11th* we had 16 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. 156A 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-song*
is visible. Below and in front of the peaks S. 31° E. and S. 12° 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.
