LESSONS IN PHYSICAL 

 GEOGRAPHY 



By CHARLES R. DRYER, M. A., F. G. S. A ., Pro- 

 fessor of Geography, Indiana State Normal School. $1.20. 



SIMPLICITY and accuracy constitute two of the chief 

 merits of this text-book. The physical features of the 

 earth are grouped according to their causal relations and 

 the functions which they perform in the world economy. The 

 characteristics of each group are presented by means of a typic- 

 al example described in unusual detail. Many realistic ex- 

 ercises, including both laboratory and field work, are intro- 

 duced whenever practicable in order to direct the student how 

 to studv the thing itself. 



COMMERCIAL GEOGRAPHY 



By HENRY GANNETT, Geographer of the United States 

 Geological Survey and the Twelfth Census; CARL L. 

 GARRISON, Principal of the Morgan School, Washing- 

 ton, D. C; and EDWIN J. HOUSTON, Emeritus Pro- 

 fessor of Physical Geography and Physics, Central High 

 School. Philadelphia. $1.25. 



THE study of commercial geography is here made not 

 only informative, but truly educative and worth while. 

 While the conditions that influence commerce in every 

 region, the cultivation of the soil, and the great commercial 

 staples are taken up, the largest part is devoted to each coun- 

 try with special reference to its industries and commerce. 

 The book abounds with diagrammatic maps, graphic diagrams, 

 and tables of every kind, showing locations and portraying 

 the present condition of the world's commerce.
