ENTOMOLOGY. 

 Extensive contributions have been made to this department, 

 in addition to the collections made by the curator, Mr. Francis 

 G. Sanborn. 



A series of boxes has been prepared for the reception of the speci- 

 mens, which are securely protected from the chief enemies of the cabinet, 

 — dust, light, and destructive animals. Tlie former collection, arranged 

 and labelled on scientific principles, having been entirely destroyed, with 

 the exception of the alcoholic portion, for want of suitable accommodations ; 

 and a different arrangement being deemed necessary for the purposes of 

 an Agricultural Cabinet, the following plan has been adopted : The front 

 of the case bears the inscription " Ixskcts of Massachusetts," 

 beneath which, the drawers, in three columns of fifteen each, are respec- 

 tively headed " Injurious," " Beneficial," and " Miscellaneous." The 

 first column is again divided as injurious ^Ho Fruit-trees" "to Timber- 

 trees" " to Cereals" &c., and contains the insects bearing those characters.
