Note 35 — CONTENTS. (continued 9)

That Tibet is not an extensive plain, according to the usual idea, has already been pointed out by Humboldt (Asie Centrale, vol. i. p. 12). Chinese geographers, according to him, describe all parts of Tibet as more or less mountainous; the eastern portion of West Tibet (Gnari) as least so. Captain H. Strachey, in his account of his visit to lake Manasarawar, says expressly that "the surface of Gnari is for the most part extremely mountainous." In the lower Tibetan course of the Sutlej, the recent discoveries of Captain Strachey show that an alluvial table-land of considerable extent exists, intersected by deep ravines.
