the legend: »Sources of the Ganges»; on the northern slopes: »Sources of the
Indus»; and on the eastern: »Sources of the Brahmaputra». I do not know how
this extraordinary map has ever been constructed. The outlines of the lakes are taken,
probably, from the Pundit's maps, as they are much better represented than on Strachey's
map. The Samo-tsangpo has exactly the same appearance as on Nain Sing's map. There
is no channel between the two lakes, although Strachey had found one which Drum-
mond may not have seen. The Satlej is drawn as going out of the Rakas-tal. But
not a single rivulet enters this lake from the Gurla. To the Manasarovar, on the
other hand, four small rivulets go down from the Gurla. And these are, obviously,
meant to be the sources of the Indus. But, as on Webber's map, the Manasarovar
has no outlet whatever, it is difficult to understand how these rivulets can ever belong
to the Indus. For he cannot know anything about a subterranean outlet and he had
no idea of the periodicity of the channel. If he had, the channel should have been
entered with a dotted line, or in full as the Satlej, which cannot possibly have gone
out of the Rakas-tal without there having been first a communication between the
two lakes.

Only the last seven miles of the Tage-tsangpo are entered with a dotted line.
If the red line of the travellers' route were entered correctly, they must have crossed
the source region of the Tage-tsangpo. But instead of this we find the uppermost
Brahmaputra stretching far to the west. It is interesting to notice that so late as
1902 a book and a map were published, teaching the world that the source of the
Indus was on the Gurla. And still, 25 years earlier, the Pundits had found out that
the Singi-kabab, or source of the Indus, had to be searched for N.E. of Kailas, and
some 140 years earlier a Catholic father knew that the Satlej, not the Indus, went
out of the Manasarovar.

It is also surprising that such an intelligent and clever man as ROBERT SHAW
could write the following words on the source of the Indus, — in spite of all that
really was known in 1867 and 1868: »It rises in the mysterious and sacred Lake of
Mansoráwar, near the source of the great Brahmaputra.» And again, about the
Manasarovar, that it is »one of the sources of the Indus».¹
