Earth Features and their Meaning 



A Textbook for Cultural Courses on General Geology

11 The purpose of ' Earth Features and their Meaning,' by Professor 

 W. H. Hobbs, is primarily to furnish a readable work on miscellaneous 

 topics of modern geology and physical geography. In his preface the 

 author lays stress on the fact that the book is a series of readings to 

 stimulate the traveler to appreciate the landscape wherever he may 

 go. A special emphasis is laid upon earthquakes, volcanoes, the work 

 of water, desert processes, and glaciers. . . . 



" The book is noteworthy for the importance given to the experi- 

 mental method in geology, for good reading references at the end of 

 each chapter, for an unusually good analysis of weathering and the 

 surface processes of dry regions, such as dune accumulations in the 

 deserts, and for original treatment of glaciation." Nation. 



" The subject matter is presented in such an interesting and intel- 

 ligent manner that the general reader and student will receive from 

 its study such an understanding of the subject that he will be able, 

 in his travels, to recognize many of the earth's features about which 

 he has read. The landscapes which are represented are very largely 

 those which are along the routes of travel. Much stress has been 

 placed on the dependence of the chief geological processes of a region, 

 upon the general climatic conditions there existing. . . . 



"This is a book which should be possessed by every teacher of 

 earth science and geology, whether hi secondary school or college. It 

 deserves and doubtless will have a large circulation." School Science 

 and Mathematics. 



11 The book is an excellent reference volume for students who are 

 interested hi a simple outline of geology. The volume has been tested 

 in class work and should prove its worth." Bulletin of American 

 Geographical Society.

" Every geographer and geologist interested in ice will appreciate 

 these clear descriptions and excellent illustrations of the earth's great 

 glaciers they make up into a most presentable book." Nature.
