place he says: ¹ »From the Mariham-la the road descends gradually, following close
to the north of the main source of the Brahmaputra, and within sight of the gigantic
glaciers, which give rise to that great river. About 50 miles from its source the
road is for the first time actually on the river . . .» First he says that the road
from Maryum-la follows the main source of the Brahmaputra, i. e. the Maryum-chu.
Then that the glaciers, i. e. of Kubi-gangri, give rise to that great river, and
finally that only after 50 miles from the source is one actually on the river.
These 50 miles bring us to Tamlung-la for the Maryum-la is only 30 miles from
the confluence. Thus it is impossible to say whether Maryum-la, Tamlung-la or
the glaciers are regarded as the source of the river. ² Although it is most likely
that he regards the branch, which I have identified as the Chema-yundung, as
the source.
Between the upper part of this branch and L. Gunkyud Cho, Nain Sing has
correctly entered a chain of mountains. But the above-mentioned mighty range
stretching N.E. from Gurla and which on his map does not give any change at all
to Tage-tsangpo, does not exist. He has entered the Kubi-gangri and its continua-
tion south of the Chema-yundung as a continuous range. He correctly places,
»Many Large Glaciers», from which three small tributaries go down to Chema-yundung.
There is no sign of the Kubi-tsangpo as in reality the confluence of that river with
the Chema-yundung takes place below the junction of the Maryum-chu and Chema-
yundung. So that although Nain Sing understood that the Brahmaputra received
the greatest amount of its water from these glaciers, he never saw the source
branch of the Tsangpo and consequently has nothing to tell us about it in his
report, nor on his map. His journey was a beautiful and admirable performance,
but as far as the source of the Brahmaputra is concerned his map is a step
backward into the darkness, — if compared with the Lamas' map. The same
must be said of his representation of the mountains S.W. of the sources. The
Lamas knew that the Gurla, the Langchen-kabab, the Tamchok-kabab and the
»M. Cocoun Kentchian» etc., all belonged to one and the same upheaval or fold
in the earth's crust. This important truth, which gives the key to the understanding
both of the orography and hydrography of these regions, has been disfigured on
