quotes a native informant who could mention even the glacier source, and Curzon submits that this native »was a better-informed and a more competent geographer than the host of big names who have succeeded him».
I have been led to quote this most interesting and valuable examination of Lord Curzon, partly to prove the important part played by glaciers when the question of head-rivers and tributaries should be considered, partly to remind of the difficulties and the many different considerations which may arise when the same question has to be settled. In the case of the Panja all the conditions speak in its favour. In the case of the Satlej, only the length and the historical opinion make the Tagetsangpo the source. As to the Brahmaputra both length, volume and historical opinion agree to make the Kubi-tsangpo the source. For the Indus again the length and historical opinion are decisive. The great importance of the glacier sources, which was so clearly pointed out already by R. Strachey and in later years by Lord Curzon, is in full agreement with my own view and observations.
