The literature of A

is voluminous and goes back to remote antiquity. Morton's Cyclopædia of A., Stephen's Book of the Farm. Loudon's Encyclopædia of A., are the more important general reference works. The Breeder's Gazette, the Cultivator and Country Gentleman, the Rural New Yorker, the American Agriculturist, Hoard's Dairyman, American Gardening, Gar den and Forest, are some of the more important American The governments of the U. S. and of the various States have from almost the first maintained a policy of State aid for the promotion and improvement of A. This first took the form of grants of money to be offered as premiums by societies organized to hold fairs and exhibitions of live stock, farm and garden crops, machinery, and the like. Later, agricultural schools and colleges were established, and still more recently large sums have been given for the investigation of problems by experiment stations and for the diffusion of knowledge through Farmers' Institutes.
