Fresh Material. — Compared weight for weight, the fodder produced in drills con- 

 tains slightly more dry matter, the increase being in the carbo-hydrates (starch, <S:c.) 

 and the fibre. 



In the more important nutrient, crude protein, the fodder from the hills is very 

 slightly the richer, and this relation holds good on further analysis of the nitrogenous 

 bodies, the percentage of albuminoids or true flesh formers being somewhat lower in 

 the corn grown in drills. These differences, with the exception of that relating to the 

 dry matter, are, however, exceedingly small and cannot in themselves be considered 

 of any great significance from the feeding value standpoint.

Dry Matter. — The only difference worthy of special notice here is the percentage 

 of protein, which is somewhat higher in the case of the hill-grown corn. This, as might 

 be expected, is accompanied by a correspondingly lower percentage of carbo-hydrates. 

 In albuminoids (the more valuable part of the crude protein), the dry matter of the 

 fodder from the hills is about thrcc-quartcjs of a per cent ('75 per cent) the richer. 



In summing up the data of the investigation so far discussed, it seems justifiable 

 to conclude that the fodder from the corn planted in drills is slightly the more valu- 

 able by reason of its larger proportion of dry matter, but that in albuminoids (the true 

 flesh formers) the hill-grown fodder is a little the richer. 



We may now consider the data of the yields per acre and thus arrive at an answer 

 to the question which was the occasion and incentive of this investigation.
