Authors Catalogue. 129 
a space of 20 pages, dismisses the subjects which constituted the 
greater part of the consideration of the land in the text-books ten 
years ago. Of the 400 pages in the text, excluding appendixes and in- 
dex, 290 are devoted to the discussion of land forms. Plains and 
plateaus are considered at some length, beginning with coastal plains, 
which are traced through their development from the young plain 
bordering the sea coast, to the old ones now situated far within the 
<rontinental border. 
In this chapter, that on "Mountains," and one on "The Waste of 
The Land," the evolution is traced by describing typical forms in 
various stages of development with reference to, but not discussion 
of, the processes of evolution. In the chapters on "Rivers and Val- 
leys," "Shore Lines" and that part of chapter XI relating to glaciation. 
the processes are described along with typical forms produced by 
them. 
There are a number of appendixes and a full index. Among other 
things, Appendix L gives many references to the literature of the sub- 
ject which will be of great value to teachers. The descriptions and 
explanations are clear and sufTiciently simple for pupils of high school 
grade. Unusual technical terms are almost wholly absent. The book 
is fully illustrated with clear and appropriate maps and photographs. 
It is of convenient size, is clearly printed on good paper and is well 
l)()und. It is incomparably the best te.xt on the subject yet issued.
