and is designed to teach the beginner the elements of the 

 science, and to serve as a guide to the more elaborate 

 treatises and memoirs which the advanced student may 

 wish to consult. In order to make it of value to farmers 

 and gardeners, whose needs the writer has kept in view, 

 concise accounts have been given of insects injurious or 

 beneficial to vegetation or those otherwise affecting hu- 

 man interests. 



The Guide is already in use in several of our princi- 

 pal colleges and agricultural schools as a text book or for 

 reference, and has met with favor from teachers and nat- 

 uralists. The first edition has been exhausted ; the ap- 

 pearance of a second indicates its just appreciation, the 

 large number of entomologists in the country, and the 

 growing sense of the importance of the study of practical 

 entomology by agriculturists.

The first field meeting, the present season, was held in Bradford, a

 and, after the announcement of the programme of the day, divided 

 into parties to visit different localities of interest, the citizens of 

 Bradford acting as guides and furnishing teams for their accommoda- 

 tion. 



Among the places visited were the old and new cemeteries, the 

 former, at the site of the first church built in Bradford, being the 

 burial place of its early ministers and many of the first settlers : 

 the town clerk's office, where several of the party spent much time 

 in examining the ancient records, and were amply repaid for their 

 trouble, by the interesting items brought out in their researches;
