CHAPTER XXVI.
THE LATEST DISCUSSION ABOUT THE TRANSHIMALAYA.
It seems as if a supernatural mystery had kept the Transhimalaya under its
spell. Even of those parts near Tengri-nor which have been crossed or visited by
a few travellers extremely little is known. Of the passes which have been crossed
we hardly know anything more than their names and their heights. Of the general
orography extremely little has been reported, and of the geology nothing. Of the
whole system, west of Khalamba-la nothing was known, except the edge, so far as
it could be seen from the route of Nain Sing and Ryder and Rawling.
In another chapter, regarding the tributaries and source of the Tsangpo, and
the sacred lake, I have dealt with Ryder's and Rawling's expedition and its beautiful
results.¹ Let us now consider the parts of the publications of Ryder and Rawling
which, directly or indirectly, have to do with the Transhimalaya.
Ryder fixed many peaks north and east of Lhasa »including some fine snow-
peaks south of the Tengri-nor, mentioned by Mr. Littledale, the highest of which
was 23 250 feet in height, and the highest peak we ever came across north of the
Tsangpo. Two other snow-peaks which I fixed are, I believe, those mentioned by
M. Bonvalot, and christened by him Mount Huc and Mount Gabet; but their heights
were disappointing, the highest being 21 500 feet».² The following magnificent survey
results were brought home: »Triangulation: An area of 45 000 square miles was
completed, connecting Lhasa with India, and fixing all prominent peaks which were
visible, with their heights. Topography: An area of 17 000 miles was surveyed on
the scale of 4 miles to the inch, of which 3 000 square miles, in the neighbourhood
of the Chumbi valley, Gyangtse, and Lhasa, were also surveyed on the scale of 2
miles to the inch. Route surveys, on the scale of 1 inch to the mile, were made of
the road to Lhasa.»
It is obvious that such a far-reaching work should sweep the whole southern
front of the Transhimalaya. And already the observation of Ryder that no high
