150 DEPARTMENT OF AGRICULTURE GEORGIA. [436] 



The importance, to farmers, of some knowledge of the 

 classification, transformations and habits of insects injuri- 

 ous to vegetation, and the necessity for the means of dis- 

 tinguishing between friends and enemies, rendered it prop- 

 er that the subject should not be omitted in a work of this 

 character. 



If what has been written shall have the effect of stimu- 

 lating careful and accurate observation and investigation of 

 insects on the part of the farmers of the State, its princi- 

 pal object will have been accomplished. Any farmer who 

 will review his experience, and estimate the injury to his 

 crops by insects during the last decade, will be forced to 

 appreciate the importance of utilizing the information sup- 

 plied by the science of Entomology. 



"Insects Injurious to Vegetation," by Harris, has been 

 freely quoted, and information derived from it utilized. 

 Those desiring more detailed information to aid them in 

 heir investigations, will do well to secure this work. 



In the preparation of this work, the following works have 

 been freely consulted, viz: How Crops Grow and How Crops 

 Feed Prof. S. W. Johnson; Scientific Agriculture Prof. E. M. 

 Pendleton ; Elements of Agriculture, Chemistry and Geology 

 Prof. F. W. Johnston ; Talks on Manures Mr. Joseph Harris ;. 

 Land Drainage Prof. John H. Klippart ; Structural and System- 

 atic Botany Prof. Asa Gray. The principal engravings have 

 been copied from Johnson, Gray and Klippart.
