Fifty years encompass the development of Physiography and also its absorption into the general body of geographic and geologic knowledge. The main principles were dimly perceived much earlier, but many of the facts are still to be gathered and some of them need reanalysis. Yet in the swift progress of human thought we are on the verge of developments by which Geomorphology is to absorb the purely geologic aspects of Physiography, Geography is trying to repudiate the genetic description of landscape and a new aspect of Geology, the Geography of the Pleistocene is to occupy the attention of a large scientific group.
