Entomologists generally are to be congratulated that the unpublished notes and 

 results of the studies of the late Professor Shngerland have here been put into per- 

 manent and usable form by Mr. Crosby. 



The volume opens with a chapter of eight pages on general considerations in 

 which are mentioned the vast amount of damage caused annually in the United 

 States by fruit insects; then- development; how they feed and how they may be con- 

 trolled. Then follow concise accounts of the principal fruit insects, according to 

 hosts, which in turn are Usted in the order of their importance. Illustrations shov^*- 

 the life stages of all the chief species. The space devoted to each kind of fruit is as 

 follows: Apple insects, 204 pages; pear and quince insects, 29 pages; plum insects, 

 24 pages; peach insects, 38 pages; cherry insects, 11 pages; raspberry, blackberry and 

 dewberry insects, 25 pages; currant and gooseberry insects, 22 pages; strawberry 

 insects, 36 pages; grape insects, 63 pages; cranberry insects, 14 pages. The book 

 ends with a chapter of 18 pages on insecticides, followed by an index of 11 pages. 



The chapter on each food plant gives a brief account of the appearance, Kfe history, 

 injuries, and remedial treatment of each species, followed by a few references to the 

 most important economic or descriptive literature. 



At the end of each main division is a hst of other insects also attacking that kind 

 of fruit, each with a reference, to an account elsewhere in the book. 



For the most part the treatment is clear and concise, yet comprehensive, thus 

 including a vast amount of information between the covers of a moderate sized book. 

 Most of the illustrations are from the well-known and excellent photographs of Pro- 

 fessor Slingerland, though some have been furnished by others. Some are from pen 

 drawings by Miss Anna C. Stryke. As a whole the figures are excellent and the 

 volume is well-printed on good paper. 



The work will be indispensable to all working entomologists and exceedingly useful 

 to all farmers, gardeners and fruit growers. It is one of the series of Rural Manuals, 

 edited by L. H. Bailey, and should find a place on the shelves of every agricultural 

 and horticultural librarv.
