502 INSECTS INJURIOUS TO VEGETATION. 



Having now arrived at the end of my work, I have only to 

 add a few remarks by way of conclusion. It has been my 

 design to present to the reader a sketch of the scientific ar- 

 rangement of the principal insects which are injurious to vege- 

 tation, not only in New England, but in most of the United 

 States. The descriptions of the insects, being drawn up in 

 familiar language, will enable him to recognize them, when 

 seen abroad, in all their forms and disguises. The hints and 

 practical details, scattered throughout the work, it is hoped 

 will serve as a guide to the selection and the application of 

 the proper remedies for the depredations of the insects de- 

 scribed. I regret that it has not been in my power to do full 

 justice to this important subject, which is far from having 

 been exhausted. My object, however, will have been fully 

 attained, if this treatise, notwithstanding its many faults and 

 imperfections, should be found to afford any facilities for the 

 study of our native insects, and should lead to the discovery 

 and the general adoption of efficient means for checking their 

 ravages.
