ANNUAL REPORTS. 251 



The practical results of this experiment seem to indicate 

 that, pound for pound, the light oats have nearly the same 

 feeding value as the heavy oats. Although the heavy oats 

 contain a higher per cent, of protein, fat and nitrogen free 

 extract, and a less per cent, of fiber than the light oats, it 

 seems probable that the relative proportions of these con- 

 stituents in the two grades are such that they are more easily 

 and thoroughly digested. Some digestion trials, however, 

 will be necessary to decide this point. The per cent, of ker- 

 nel, as would be expected, bears a close relation to the weight 

 per bushel. It should be remembered that although the two 

 grades are practically equal, pound for pound, they are not 

 equal, quart for quart, and that in feeding by measure, as is 

 usually done, due allowance should be made for the heavy 

 oats and a less quantity given. Since oats are bought and 

 sold by weight instead of measure there seems to be no gain 

 made in buying the heavy oats at a much advanced price 

 over the light oats. 



IV. Drainage. 



A complete system of underdrainage was installed in the 

 permanent plots referred to in the beginning of this report, 

 4,390 feet of drain tile being used. With this work as a 

 practical basis, bulletin No. 118 was prepared. This bulletin 

 which discusses the principles and practices of tile drainage 

 as applied to New Hampshire conditions was the only publi- 

 cation issued by this department during the year.
