Hunt, 1904; Bulletin No. 133 of the Department of Agri culture of the Commonwealth of Pennsylvania,1904; The A B C of Corn Culture, P. G. Holden, 1906;

References on growing maize for the silo follow: Henry, Feeds and Feeding, published by the author, Madison, Wis.; Voorhees, Fertilizers, Macmillan Company, New York City ; King, Physics of Agri culture, published by the author, Madison, Wis.; Woll, Book on Silage ; Shaw, Soiling Crops and the Silo, Orange Judd Company; Miles, Soiling, Ensilage and Silage ; Illinois Station, Bulletin No. 43 ; New York State Station, Bulletin No. 97; Ohio Station, Bulletin No. 5 ; Farmers' Bulletin, United States Department of Agriculture, No. 32. Several other state experiment stations have discussed silage in bulletins and reports, and information will be found in reports of Farmers' Institutes. The Agricultural Press is a very fruitful source of information.
