BOOK NOTICE. 



Insects and Insecticides, by Clarence M. Weed, Hanover, N. H., 1891. 



Under the above caption Dr. Weed has published a small volume of 

 281 pages, well printed and copiously illustrated, which will be found most 

 useful by those for whom it is prepared — the farmer, the fruit grower, the 

 floriculturist, and the housekeeper. The work consists of an introduction 

 and six parts. The introduction gives a concise account of the transfor- 

 mations of insects, which are illustrated by the life history of Papilio 

 asterias, the Celery Caterpillar, for those which have a complete meta- 

 morphosis, and the Chinch Bug for those which pass through incomplete 

 transformations. The differences between biting and sucking insects are 

 explained, and the natural enemies of injurious insects are treated of. 

 There is then a summary of the different insecticides, and the best 

 methods of applying them. The introduction closes with short instruc- 

 tions for collecting and preserving insects. 



Fart I. treats of Insects Affecting the Larger Fruits — apple, plum, pear, 

 cherry, peach. 



Part II. — Insects Affecting Small Fruits — strawberry, currants, goose- 

 berries, raspberry, blackberry and grape. 



Part III. — Insects Affecting Shade trees, the Rose and House 

 Flowers. 



(Parts 1-3 of Dr. Weed's work have appeared previously in a small 

 edition issued by the Columbus (Ohio) Horticultural Society.) 



Part IV. — Insects Affecting Vegetables — tomatoes, potatoes, celery, 

 squash, cucumber, bean, pea, cabbage, onion, asparagus and rhubarb. 



Part V. — Insects Affecting Cereals and Forage Crops — Indian corn, 

 wheat, clover, grass. • 



Part VI. — Insect Pests of Domestic Animals and the Household. 



On the whole this is a very useful and attractive volume, well arranged, 

 easy of reference, and well illustrated. The accuracy and quality of 

 Dr. Weed's scientific work are now too well known to need any comment, 

 further than to say that this his last publication is up to his usual excellent 

 standard. J. F.
