The general outcome for the five years is slightly favorable to 

 the large variety of corn if we consider only the yield of digestible 

 dry matter. But when we take account of the fact that in the one 

 case an average of five and one-half tons more of material have 

 annually been handled over several times, we are led to conclude 

 that the smaller, less watery variety of corn has really proved the 

 more profitable. It is significant, also, that the largest yield of 

 dry matter in any instance has been from the small variety. 

 TVhile the Flint corn grown in this State is not capable of storing 

 so much dry substance as the large varieties of Dent corn, under 

 circumstances equally favorable for both, the latter cannot in this 

 latitude reach anything like maturity, and so loses the advantage 

 of that period when growth is most rapid. 



SU:iIlIARY. 



(1). The average weight per acre of the green crops for five 

 years were: Southern Corn, 34,761 lbs.; Maine Field Corn, 

 22,269 lbs. ; difference, 11,492 lbs., or nearly five and three- 

 fourths tons. 



(2). The average dry matter per hundred pounds was nearly 

 one-third more in the Maine Field Corn, the relation being 

 Southern Corn, 14.50 lbs. ; Maine Field Corn, 18.75 lbs., or as 

 100: 129. 



(3j. The Maine Field Corn proved to be the more digestible, 

 the relation for dry matter being : Southern Corn, 65 per cent ; 

 Maine Corn, 73 per cent., or as 100 : 112. 



(4) . The average pounds of digestible dry matter per hundred 

 pounds of green corn have been : Southern Corn, 7.25 lljs. ; Maine 

 Field Corn, 13.69 lbs., or as 100 : 189. 



(5). The average yield of dry matter per acre has been: 

 Southern Corn, 5,036 lbs. ; Maine Field Corn, 4,224 lbs. 



(6). The average yield of digestible dry matter has been: 

 Southern Corn. 3,251 lbs. ; Maine Field Corn, 3,076. 



(7). The yield of digestible dry matter has averaged 175 lbs. 

 more with the Southern Corn. To offset this it has been necessary 

 to handle annually five and three-fourths tons more weight. 



(8). The largest as well as the smallest yield of digestible 

 matter in a single year has come from the Maine Field Corn.
