 Julia Richman High School, New York. 8vo, cloth, x+ 528 pages, illustrated. 



MANUAL OF SUGGESTIONS FOR TEACHERS to accompany " Elemen- 

 tary Biology." J2mo, cloth, 95 pages, illustrated. 



HITHERTO the knowledge of biology has been regarded as an end 

 in itself. Here it is considered as a weapon by means of which man 

 may conquer his surroundings. The student learns not only what 

 biology is, but how it can be used. Application of the principles 

 learned is immediate and practical. The problems presented and 

 suggested are such as affect the welfare of individual, community, 

 and race. 



In method the book is inductive. Pupils learn rather to observe 

 what plants and animals do and how they do it than to memorize 

 lists of organisms and their functions. 



CIVIC BIOLOGY 



By CLIFTON F. HODGE, General Extension Division, University of Florida, 

 and JEAN DAWSON, recently head of the Department of Biology, Cleveland 

 Normal School. 8vo, cloth, viii + 381 pages, illustrated. 



THIS book provides a well-organized course in high-school biology 

 that places the emphasis on the practical applications of the subject, 

 particularly to community problems. The keynote of the whole argu- 

 ment is united effort to prevent the enormous losses in destruc- 

 tion of natural resources, in unfruitful labor, in damage to property, 

 in preventable disease now common because of insufficient civic 

 organization and to preserve valuable species from extermination.
