in this manner are something more than mere gossip, as, if accurately 

 observed and recorded where they are accessible to the busy man, these 

 notes will sooner or later prove invaluable in the study of insect diffusion 

 and disappearance. 



BOOK NOTICE. 



Insects Injurious to Staple Crops. — By E. Dwight Sanderson. B. S. 



Agr., Entomologist, Delaware College Agricultural Experiment Station. 



New York : John Wiley & Sons. (Price $1.50.) 



This is a very satisfactory compilation of the information to be 

 obtained from the publications of State Agricultural Experiment Stations 

 and of the Division of Entomology at Washington, regarding a considerable 

 number of insects of practical interest to farmers. The writer lays no 

 claim to originality, but he has succeeded in preparing a useful book, full 

 of information of a trustworthy character, arranged in a convenient 

 manner, and sufficiently illustrated. Some of the photogravures, 

 however, are by no means as clear as one would wish. The book 

 is intended for the use of farmers, and aims at giving them a correct 

 knowledge of the insects with which they may have to contend and the 

 methods that have been found most serviceable for preventing or con- 

 trolling their injuries. Whether the ordinary farmer can be induced to 

 read and make use of a book of this kind is somewhat doubtful, but if he 

 does it will surely repay him well for any effort he may put forth in doing 



so. 



The work opens with a short account of some of the most startling 



losses caused by insects, which must give the reader a vivid idea of their 

 importance. After a chapter on the structure and development of insects, 

 there follows a very useful epitome of the methods of intelligent farming, 

 which will be found effective in preventing insect injury. A chapter is 

 devoted to beneficial insects, in order that the farmer may know friend 

 from foe, and the greater part of the book to descriptions and life- 

 histories, together with remedies, of insects affecting various grain crops, 

 corn, clover, cotton, tobacco, hops, potatoes, and sugar beets. The work 



is completed by an account of the most useful insecticides and the 

 formulae for their preparation. On the whole, it is an excellent manual, 

 and vvill be found a handy book for reference by all who are engaged in 

 the practical work of fighting against insect foes.
