Excerpt from The Physical Geology of the Don Basin This volume was completed and the MS. left the writer's hands during the Spring of 1914. Though it contains no statement he wishes to withdraw, there are many points on which further study has shed new light and on which fuller information could now be given. The theory of river-terracing, for example, should be amplified so as to bring out the importance of conditions determining the formation of river islands and their incorporation in the flood-plain. Along Dee and Don every terrace (now or once part of a flood-plain) of any extent is traversed by a larger or smaller number of anastomosing hollows, plainly former channels of the river or of branches of it; and terraces of all types but particularly ordinary Lateral Terraces (p. 84) have been extended by the accretion of island to flood-plain through the desertion and subsequent obliteration (by flood loam, plant growth, etc.) of secondary channels. In the vast majority of instances this has not been brought about by the severing of spurs (p. 96) as Prof Davis seems to imply has been the case along New England rivers. The list of glacial striae, too, could now be greatly extended. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
