FOREWORD 



The Manual for the Study of Insects, published in 1895, was written 

 to meet the needs of teachers of Entomology when that science was in its 

 infancy as an academic study. It was well received and accomplished its 

 purpose, and there has been a continuous call for it since; it is now in 

 its eighteenth edition. Owing to the rapid development of the science it 

 became necessary to revise the book and I began this before my retire- 

 ment in 19 14. However, so great has been the growth of Entomology 

 that this intended revision of the Manual resulted in a new textbook, 

 An Introduction to Entomology. 



I still had it in mind to revise the Manual, making it more elemen- 

 tary, when failing health prevented. It is with relief and confidence that 

 I pass this task on to Professor Glenn W. Herrick, whom I trained when 

 he was an undergraduate and who has now many years of successful 

 teaching and careful research to his credit.
