and opinion concerning many of the funda- 
mental problems of North American geology, 
and form an admirable supplement to earlier 
treatises and manuals. 
The value of the book is greatly enhanced 
by the fifteen paleogeographic maps by Bailey 
Willis which accompany the papers. 
§ The Eagle Creek formation is 
exposed along the bottom of the 
Columbia River gorge on the Ore-

The Geography of the Ozark Highland of Missouri 
By CARL ORTWIN SAUER, the University of Michigan 
(Publications of the Geographic Society of Chicago) 
The Ozark Highland of Missouri was selected for investigation because of its 
unusual wealth of geographic responses and because little is known concerning its con- 
ditions and possibilities. 
The purpose of such a study is twofold: to eras an adequate explanation of 
the conditions of life in a given area, and to contribute proved statements which will 
aid in working out fundamental principles. 
The book is divided into three parts. The first is an outline of the environment. 
Only those things which are pertinent to an understanding of the conditions under which 
the people live are introduced. 
The second part considers the influence of environment on the settlement and develop- 
ment of the different parts of the highland. 
The third part is a study of the economic conditions as they exist today. In conclusion 
a forecast is offered of the lines along which the future of the region will be worked out. 
A valuable feature of the volume is the 44 figures in the text and 26 plates.
