 The author of this excellent manual is so well known as a thoroughly 

 skilled economic Entomologist from the numerous Bulletins that he has 

 written, that it is hardly necessary to say a word regarding the accuracy, 

 clearness and practical character of the book. All the insects that any 

 vegetable grower is likely to meet with are described and figured, and plain, 

 simple methods of control are given. The first four chapters give a brief 

 account of the various orders of insects, the natural elements that control 

 them, prevention by farming and mechanical methods, and the most 

 approved insecticides, with directions for making and using them. The 

 remaining chapters give full information respecting a great number of 

 insects arranged under the vegetables that they attack. A list of publica- 

 tions on Economic Entomology and a copious index complete the work. 

 Everyone who possesses a garden and tries to grow vegetables, sliould 

 have this volume at hand for speedy reference when any insect foe attacks 

 his crops ; all the information needed for identifying the enemy and 

 waging successful warfare against him can at once be found, and with little 

 difficulty be put in practice. Students in Agricultural Colleges and 

 teachers of Nature Study will also find miich assistance in their work from 

 the perusal of this volume, and will continue to regard it as a mine of 

 useful information.
