PRESS NOTICES 



" This book gives in an exceptionally dear and concise way the 

 approved practices relative to insect control, and of the principles in- 

 volved. The authors have rendered a distinct service in preparing this 

 book. It . . . occupies a useful place in the working library of 

 economic entomologists generally.'' — Journal of the Ainericaii Socieiy 

 of Agronomy. 



"... the first exhaustive work on one of the most important 

 problems of the day. 



" Papers on the theory and practice of control are usually issued in 

 technical journals, and in various languages. Many are difihcult to 

 obtain and the student is hampered ; here, aided by an excellent biblio- 

 graphy, the work accomplished or attempted is explained, and an 

 invaluable review of economic progress is placed within reach of 

 entomologist, horticulturist, and agriculturist. The book will be of 

 value in every civilised land." — T. A. C. in tlie Manchester Guardian. 



" Messrs. Wardle and Buckle have rendered a distinct service in 

 providing an excellent resume of the present-day position with regard to 

 insect control. The volume should appeal to economic entomologists, 

 since it covers the whole field of a subject which has not been previously 

 surveyed in so comprehensive a manner." — Nature. 



"The authors are to be congratulated in presenting this compilation, 

 which covers a very wide field, in such an interesting and readable 

 manner.' — Science Progress.
