Abstract
GLOBUS for September 1, Bd. xcviii., contains an article of some interest on the subject of the influence of river systems in the East, by Herr Ewald Banse. The author deals with the area between 17° and 36° N. lat. and 17° W. and 74° E. long, (which he terms the Orient), where the average annual rainfall is less than 200 mm. (8 inches); this is bordered in the southern Sahara and in the northern part of south-western Asia by a broad zone with an annual precipitation of 600 mm. (23½ inches). In summer this area is the hottest part of the earth's surface. It tends to prevent the intermingling of various flora, fauna, and human races; the Arabian peoples, the one-humped camel, and the date-palm are mainly confined to it. The map accompanying the article shows three main areas, which are drained by no rivers—the Saharan, the Arabo-Syrian, and the Irano-Armenian, the undrained regions amounting to 77 per cent. of the Orient.
