138, where the height is 4 167 m, although the village and the monastery are situ-
ated at a considerable height above the bottom of the valley. Some of the sur-
rounding mountains are of considerable height, as one to the S.E. and another
S.W. called Takpo-che and falling steep down to the Mü-chu valley at Tong. To
the N. 86° W. is a rocky massive at the side of a right tributary called Kanin-lungpa;
to the N. 62° W. is a rounded peak, Ya-munja between Mü-chu and a right tri-
butary; at a greater distance N.W. is the peak Ya-metsik with some snow. The
mountain at the southern foot of which the monastery, Lung-gandän, is built, is called
Ya-yüra. From N. 80° E. enters a valley Tong-pu-chen which is separated from
Tongchung by mount Tovakü. The village Tong is built on the terrace of gravel
and blocks which has its root in the mouth of Tong-pu-chen; the fields are
amphitheatrically arranged like a staircase down the slope; bushes and poplar trees
are not rare.
Northwards from Tong the valley of Mü-chu remains as narrow as before;
the rise is slow, the river seldom forming rapids. The fluvial terraces are well de-
veloped the whole way up, especially at the right or western side, where they are
30 to 40 m high. Granite prevails. From the west enter the tributaries Tina
and Tso, both of them having fairly high snowy mountains in the background, making
the impression of a crest parallel with the valley of the Mü-chu. Hlelung-pu comes
from the east and has also a little brook from snow-fields and springs. Lingbo-pu
is also a valley from the west with a sharp ridge in its background. Ghe-pu is a
comparatively big valley from the east; in its upper regions there is a partly snow-
covered massive called Tsa-la, a name which rather indicates a pass. In the region
of Ghe the Mü-chu is said to be at its greatest in the beginning of August when it
can nowhere be crossed. Here the right or west side of the Mü-chu valley is rocky
and steep, the left has more gradual and rounded slopes. As a rule the river follows
the middle of the valley, only forced by the fans of the tributaries to turn over to
the opposite side of the main valley. Thus for instance the Ghe valley and its fan
press the Mü-chu over to the right side of the main valley.
On the section from Ghe to Sirchung we notice the following left tributaries,
i. e. coming from the east: Tangma, which has a brook and in the surroundings of
which grey granite stands in living rock; Rogam, which is very small; Chepu, a
considerable valley coming N. 87° E., with a local road to its upper part, but not to
a pass; it has many small side valleys, the openings of which are seen some distance
upwards; Shavo or Shao and Ship are small valleys; Gilung opposite to Sirchung is
comparatively great, although it is said to be only two days' journey to its origin
at Nere. Above Nere is the pass Chang-la, beyond which follow the regions of
Ngartang and Ye-pu; Ngartang is my Camp 122 between Dangbä-la and Ta-la,
and Ye-pu the upper region of Rung-chu. The information is so far interesting as
it proves there is a direct road from Sirchung to Ngartang, some three days long
and crossing the water-parting between Rung-chu and Mü-chu in a pass, Chang-la
