Professor J. W. Gregory has been giving his University in Glasgow a summary of the results of his recent explorations in Chinese Tibet. He says that the country owed its intensely mountainous character to the interaction.of mountain-forming movements of two very different dates. The earlier of these movements gave rise to the Indo-Malayan mountains which formed the backbone of Indo-China and the Malay Peninsula. Those mountains were formed by the movements known. as the Hercynian which happened after the end of carboniferous times. The younger mountain system was the Himalayan, and it was geologically quite modern, the movements having culminated about the Miocene.
With regard to the problem of the parallelism of the three* great rivers of Chinese Tibet, the lecturer said the Himalayan movements raised a continuous mountain rim around Southern Tibet, and the drainage from Tibet was then doubtless all eastward across centr. al China. Most of it now flowed southwards through clefts in the mountain rim of southern Tibet. The problem was whether the three gutters through which the rivers floved were worn out by the rivers themselves or were made by some other geographical agent. That the latter view was correct seemed to
