COMMENTS. 
‘This volume of the Rural Science Series not only gives a complete history 
of this comparatively new and important subject, but is a valuable manual as 
well, which should be in the hands of every farmer, gardener and fruit-grower. 
I shall take pleasure in recommending it to my students and others.” 
B. C. BUFFUM, 
The University of Wyoming Agricultural College, Laramie, Wyo. 
‘“This is a book for every gardener and every one who has a garden, for 
every fruit-grower and every farmer. The necessity of spraying for a great 
variety of garden, field, and fruit crops is now so generally recognized that a 
manual on the subject has become a necessity. The destruction of injurious 
insects and fungi occupies an important place in the operations of gardeners, 
farmers, and fruit-growers, and the very careful and elaborate manner in 
which the subject is treated in this volume is highly creditable to the author, 
and commends it to the attention of every cultivator.”’—Vick’s Monthly.
