YIELDS OF SOUTHERN AND MAINE CORN. 135 



markable fact, when we remember that skim-milk, even 

 when obtained by the separator process will contain 

 nearly ten per cent, of solid matter. 



In speaking of corn intended to be cut for forage at 

 an immature stage, Prof. Robertson, of Canada, said at 

 a Wisconsin Farmers' Institute, "Fodder corn sowed 

 broadcast does not meet the needs of milking cows. Such 

 a fodder is mainly a device of a thoughtless farmer to 

 fool his cows into believing that they have been fed, when 

 they have only been filled up." The same applies with 

 equal strength to the use of large, immature Southern 

 varieties of fodder, or for the silo, in Northern States. 



In comparative variety tests with corn in the North, 

 Southern varieties have usually been found to furnish 

 larger quantities per acre of both green fodder and total 

 dry matter in the fodder, than the smaller Northern vari- 

 eties. As an average of seven culture trials, Professor 

 Jordan thus obtained the following results at the Maine 

 Station. 



COMPARATIVE YIELDS OF SOUTHERN CORN AND MAINE 

 FIELD CORN GROWN IN -MAINE, 1888-1893. 



The average percentage digestibility of the dry sub- 

 stance is 65 per cent, for the Southern corn, and 72 per 

 cent, for the Maine field corn, all the results obtained for 

 the former varieties being lower than those obtained for 

 the latter. While the general result for the five years, so 

 far as the yield of digestible matter is concerned, is
