Abstract
WHEN Dr. Stein visited Central Asia in 1900–1, to explore the ruined cities of Chinese Turkestan, he included in his equipment a phototheodolite, with which a number of panoramas were taken. These not only served as a basis for the production of a map, but gave an excellent idea of the character of the country passed through. The Royal Geographical Society has now published a selection from them which will prove of interest to both geographers and geologists. A feature common to a large number of the photographs is the manner in which they illustrate the progressive desiccation of the region lying north of the Himalayas; the sharp crested ridges, separating deeply-cut valleys, produced by the action of rain and rivers, are seen to be gradually merging into rounded contours under a growing mantle of wind-borne loess. We may also direct attention to the remarkably perfect specimens of embankment moraines in the Ab-i-Panja valley, where glaciers, now vanished, have advanced into the main valley over embankments of the débris which they have carried along with them.
