Further east for 30 li the *Man-chu-tsang-pu-ho* comes from north to meet the river.
[The river *Man-chu-tsang-pu*, otherwise called the *Ma-chu-tsang-pu-pi-la*, lies in
the south-west of the Sa-ko tribes. Two streams flow for more than 200 li south-
wards from *Hsich-êrh-chung-shan* and *Pieh-lung-shan* on the north. After receiving
three streams coming from *Kang-chung-cha-ta-ko-shan* on the east, and further one
from *La-ko-tsang-cho-li-shan* on the west, the river becomes the *Man-chu-tsang-
pu-ho*, and flows south-eastwards for 50 li before entering the *Ya-lu-tsang-pu* River.]
The river flows further eastwards for 60 li, and receives a stream coming from
south. Further east for 70 li a stream comes from *A-li-tsung-chêng* on the south
to meet it. Further east for 80 li, it turns to the north-east, and meets the *Sa-ko-
tsang-pu-ho* which comes from Lake *La-pu* on the north-east, and which at first
flows south-westwards but after gathering several streams turns south-eastwards to enter
the river. [The river *Sa-ko-tsang-pu*, otherwise called *Sa-êrh-ko-pi-la*, lies on the
south-east of *Sa-ko* Province. Its source is Lake *La-pu* on the north-east, and at
first flows underground, and appearing on the surface, it has a sinuous course to-
wards south-west for more than 400 li. A stream comes from *Pi-pu-ta-ko-la-ko-shan*
on the north, and taking a south-easterly course and receiving a stream from *La-
lung-a-êrh-shan* on the north-east, flows southwards to meet the river. Flowing
further south-west for 150—160 li, another stream comes from north-west, and further
170 li south-west a stream from *La-pu-kang-chung-shan* on the north-east. Further
100 li south-west, a stream from *Lung-kan-shan* comes from the west to meet the
river. The river now flows southwards for 60 li, then turns south-westwards, and
receives a small stream from the north; further to south-west it receives another from
the west. The river then takes a southerly course, and after receiving two streams
from *Kang-lung-shan* and two from *Chao-yu-la-chung-shan* on the north-east, turns
to the south-west, and receives further a stream coming from *Chi-pu-lung-shan* on
the south-east with another from the east. The river flows further for 80—60 li
south-westwards, then south-eastwards. The river is called the *Sa-ko-tsang-pu-ho* from
here down to the confluence with the *Ya-lu-tsang-pu* River for 150—160 li. The
length of the river is 1,000 li long.» ¹
Here again, in the description of the rivers of Hsi-tsang or Tibet, the source
of the »Yaru-tsangpo-chiang» or Brahmaputra is placed in the »Tamchuk-khapap-
shan». We are told that the north-western part of the Tamchok-kabab mountain is
near the »Langchien-khapap» mountain, which, in this description is called the source
of the lake Mapam or Manasarovar. This is also interesting because it does not
leave any doubt as to *which* affluent to the lake the Chinese text regards as the
source or main feeder of the lake, namely Tage-tsangpo. The statement is im-
