First, in regard to yields, the average obtained from the crops of three successive 

 seasons was one ton more per acre from the corn planted in drills. This increase in 

 yield means 937 lbs. more of dry matter per acre, comi^osed of 19 lbs. protein (albu- 

 minoids), 658 lbs. carbo-hydrates, 2 lbs. fat, 224 lbs. fibre and 34 lbs. ash. 



In spite, therefore, of the slightly higher feeding value of the dry matter of the 

 hill-grown corn (due to its containing more protein), more real cattle food was 

 obtained per acre from the corn in drills, by reason of the latter giving a larger yield 

 of fodder containing a higher percentage of dry matter. 



We do not wish to exaggerate the differences here indicated in favour of planting 

 in drills. Though significant, they are by no means large, and it is quite possible 

 that with other varieties of com they might be considerably modified. The general 

 imiDression among those who have planted in both ways is that hill-grown corn pro- 

 duced the larger number of ears, and the analysis bears out this contention ; the larger 

 yield obtained from the drills, however, more than offsets this advantage. 



Dent and Flint Varieties. — It will be remembered that two Dent and two Flint 

 varieties Avere employed in this research, consequently the data obtained may serve 

 to make a comparison between Dent and Flint corn as regards yield of fodder and the 

 relative value of that fodder.

The fodder (fresh material) of the Flint varieties, compared weight f*r weight 

 with that from the Dents, is seen to contain the larger amount of dry matter. The 

 difference is not a large one, but the superiority of the ' Flint ' fodder is still further 

 emphasized by the fact that its dry matter is richer in albuminoids and possesses less 

 fibre. 



In the second table, to be found on page 168, we present the data of the yields and 

 ■weights of nutrients per acre from the Flint and Dent varieties examined.
