ing, White and Yellow Dent ; in the Central and Western States, the 

 Learning, Sanford, Flint and White Dent are best adapted. In the 

 south, the Southern Horse Tooth, Mosby Prolific, and other large 

 dent corns are preferred." 



For Canada, Rennie suggests for Northern Ontario, King Phillip's 

 North Dakota and Compton's Early Flint varieties; for Central On- 

 tario, the larger and heavier varieties, as Mamm'oth, Cuban, and Wis- 

 consin Earliest White Dents. A strain of Learning corn is also being 

 grown considerably for silage purposes in southern and central 

 Canada. 



King, of Wisconsin, recommends for northern United States the 

 earliest maturing dent varieties and the largest flint varieties. The 

 flint varieties will stand thicker planting than the dent varieties. He 

 further states that those varieties that will mature 3 to 5 stalks 

 per hill 3| feet apart will produce more fodder and of better quality 

 than when planted thinner. 



*The best variety of corn to plant is that which will mature and 

 yield the largest amount of grain to the acre, since the grain is the 

 most valuable part of the corn plant. The variety commonly grown 

 in any particular locality for grain will also be the most satisfactory 

 to grow for silage. As will be seen from the table below, taken from 

 the First Annual Report of the Pennsylvania State College, 63 per 

 cent of the digestible food materials present in the corn plant are 

 found in the ears and 37 per cent in the stover.

THE TIME OF HARVESTING. As maturity advances the con- 

 tent of water is lessened, which, of course, corresponds to an mcrease 

 of dry matter. The nitrogenous substances and the oil decrease in 

 comparative percentage to the rapid increase in the content of starches 

 and sugars.

 New York, substantiates the above statement :
