At a later occasion¹ Dr. Longstaff has made a very able and interesting his-
torical analysis of the changes he supposes have taken place with the source of the
Satlej. Formerly, he says, the river from Maryum-la and viâ Gunchu-tso was the
source of the Satlej. ²So we regarded the Tokchen river, with a course of about
30 miles, as the prime source.² Now, so far as this question has not been thoroughly
examined by anybody at the very place, this argument has no value whatever. For,
the fact that Alexander Gerard, who never visited the place, creates the salt lake
of Gunchu-tso as the source of the Satlej, is no argument. Then, talking of the
Tage-tsangpo, he says: ²another link in the chain is giving way between Rakas-
tal and Tirthapuri, and when this process is complete, and the Manasarovar basin is
quite cut off from the Sutlej, another source will have to be found.² As I have
shown in the previous chapter this view is perfectly correct: as soon as the lakes
are completely cut off from the Satlej, — but not a day earlier! — another source
will be found, probably the Darma-yankti. So, as he agrees with my view in this,
the cardinal point of the whole problem, the rest of his discussion is superfluous.
But the conclusion, at which he arrives, is surprising: ²Indeed, if we accept Dr. Sven
Hedin's own definition, we cannot even now locate with certainty the genetic source
of the Sutlej.² But, in the preceding passage, he had accepted my definition. So
long as the lake basin is not completely cut off, it must belong to the Satlej, and
as soon as it is quite cut off, it will have to be regarded as a self-contained (²abfluss-
loses²) basin with salt lakes in its lowest part, of the same kind as those which are
so very common on the highlands of Chang-tang. This stage in the development
has not yet entered, and until it comes we have to content ourselves with the act-
ual state of things and to describe and define the physico-geographical phenomena
as they are and not as they may happen to become in a near or distant future, if
one or the other eventuality should take place. For of the present state of things
we know, of the future we can only guess. Prognostications are always allowed,
but compared with observations they have no value at all.
Captain Rawling asks: What is a source?² And answers: ²I maintain, though
it is possible I am in error, that it is the longest visible branch of a river system,
and, if there are two branches of equal length, then that which carries the most
water at its greatest flood.² This is not the place to discuss the definition of a
source. Professor Supan³ shows that no general law can answer the question: where
is the source? Every river system has a character of its own. If really, which is
