e PREFACE. 



deal intelligently with this subject has not hitherto been 

 easily accessible, having been diffused chiefly among a large 

 number of voluminous State and Departmental reports and 

 books on scientific entomology, Vhere the practical knowledge 

 is so much encumbered with scientific and other details as to 

 make the acquisition of it too laborious a process for those 

 whose time is so fully occupied during that period when the 

 information is most needed. 



It has been the aim of the author of this work to bring 

 together all the important facts relating to insects known to 

 be injurious to fruits in all parts of Canada and the United 

 States, to add to the information thus obtained the knowl- 

 edge he has acquired of the habits and life-history of many 

 of our insect pests by an experience of over twenty years 

 as a fruit-grower and a student of entomology, and to pre- 

 sent the results in as concise and plain a manner as possible^ 

 avoiding all scientific phraseology except such as is necessary 

 to accuracy. 



The arrangement adopted under the several headings, by 

 which the insect pests which attack the different parts of the 

 tree or vine under consideration are grouped together, will, it 

 is hoped, with the aid of the illustrations, greatly facilitate 

 the determination of any injurious species. When having 

 before him its history briefly traced and the remedies which 

 have been found most useful in subduing it, the reader will 

 at once be enabled to decide as to the best methods to be 

 employed. 



The author desires to make the fullest acknowledgmept to 

 those of whose work he has availed himself. The writings
