The book is made attractive by many pictures each of which tells its own 

 story and there are also two colored plates one of the passenger pigeon already 

 extinct and one of the sage grouse almost extinct ; there are also several poems 

 which are good literature and pertinent. Every child in America ought to 

 personally possess this bock; but as this is impossible it should be in the 

 libraries of all the schools and of all the Boy Scouts and Camp Fire Girls. 



Insects of Economic Importance. Glenn W. Herrick, Professor of Economic 

 Entomology, Cornell University, i75pages, $2. 25, MacMillan Co. 



This is a terse and practical volume, dealing with remedies for the insect pests 

 of orchard, small fruits, vegetables, hops, tobacco, cereal crops, clovers, cotton, 

 stored grain, greenhouse plants, shade trees, farm animals, poultry and of the 

 household. The first chapters of the book deal with: Losses caused by 

 Insects, Useful Insects, Entomological literature, Natural Methods of Insect 

 control, Artificial methods of insect control, Poison insecticides, Fumigating 

 substances, Miscellaneous Means of Insect Control, Dusting, Quarantine and 

 Insecticide laws. 



In discussing the insects, there is first given an account of the habits of the 

 insect and the nature of its injuries and then methods of controlling it. 



Because of its brevity, clearness, thoroughness, up-to-dateness and reliability 

 this volume is of great importance to teachers of gardening or to anyone who is 

 a householder.
