On the results of his journey Webb wrote to Colebrooke: Considering the most important information gained, to be a knowledge that the sources of the Ganges are southward of the Himālaya, I subjoin my reasons for adopting this opinion. And he gives the reasons why it is proved by his journey that the source or sources of the Ganges are situated on the southern side of the Himālaya,¹ and he adds, that from intelligent natives he had their assurances, that no river, except one, exists westward of the Mānasāróvara lake; that this stream is called the Saturuz (Satalaj) river; and that it turns southerly west of Jamoutri.²
Although Webb had no opportunity to visit the lakes himself, he was clever and critical enough to gather reliable information about them, and he had a very sound and clear view of the complicated hydrography.
Colebrooke agrees with Webb, but it is difficult to understand his entire meaning in saying: »it is presumable, that all the tributary streams of the Ganges, including the Sarayu (whether its alledged source in the Mānasarovara lake be credited or disbelieved), and the Yamunā, whose most conspicuous fountain is little distant from that of the Ganges, also rise on the southern side of that chain of mountains. From the western side of the mountains, after the range, taking a sweep to the north, assumes a new direction in the line of the meridian, arise streams tributary to the Indus, and perhaps the Indus itself.³ On the other hand he is right in finding it »probably true, that the sources of the Sampoo or Brahmaputra and its tributary streams, are separated only by a narrow range of snow-clad peaks from the sources of the rivers which constitute the Ganges, or which serve to swell its stream«.
Colebrooke finishes his highly interesting and able remarks in pronouncing an opinion which is not strange for 1810, namely, that probably no other mountains than the Cordilleras de los Andes were higher than the Himalayas. In another article³ he explains the causes why he thought it wise to speak of the Himalayas as only second in height.
On a later occasion Webb got another piece of reliable information about the sacred lake. It was in 1816 when he ascended the then almost unknown passes,
