BOOK NOTICES. 



Injurious Insects of Michigan, by A. J. Cook, of the Michigan State 

 Agricultural College, 8vo., 48 pages, with numerous cuts. We are indebted 

 to our esteemed friend Cook for a copy of this excellent report, in which 

 is contained a concise summary of most of the facts known relating to 

 the life history of a large number of our most injurious insects, with the 

 best means of subjugating them. It is intended as a practical hand book 

 to guide the agriculturists of Michigan, a purpose it is well qualified to 

 serve. 



We have also received from the same author a copy of an address 

 delivered by him on Phylloxera vastatrix, at Munroe, Mich.; 8vo., pp. 10,
