 is questionable if the National Department of Agriculture at AVnsh- 

 ington has done more, or better work in this respect. 



LIBRARY. 



A well selected Library of agricultural books, is an important 

 part of a State Department of Agriculture. An office for the At- 

 torney General of the State without a suitable law library, would 

 be deficient in an essential part of its equipment, and yet it is no 

 more necessary for the proper performance of his duties, tlian is a 

 library of reference for the Secretary of Agriculture and his Di- 

 vision officers. They are continually called upon for information 

 upon important scientific and practical questions, and ought to 

 have at hand the latest and best authorities upon these subjects. 

 to which to refer. The scope of the Department is so wide, and the 

 questions that come so important, that no ordinary library of refer- 

 ence will be adequate for its use.
