For reference purposes the teacher can easily get some of 

 the following works on general entomology: Comstock's Man-

 American Insects (Henry Holt & Co., New York) ; Packard's 

 Text-book (Macmillan Co., New York); Folsom's Entomology 

 (P. Blakiston's Son & Co., Philadelphia). 



On injurious insects we have Smith's Economic Entomol-

 Injurious to Vegetables (Orange Judd Co., New York); and 

 Harris' old but useful work, Insects Injurious to Vegetation. 



For fuller information than is given in these books, one 

 must look to the following publications which contain the great 

 mass of our knowledge on economic entomology: Bulletins 

 and Reports of the State Experiment Stations and of the State
