The silage gave, in round minibcrs, 7,100 pounds of dry matter per 

 acre, 4,400 pounds of wliicli are estimated to be digestible, and the 

 beets, 3,750 pounds per acre, all of which is assumed to be digestible. 

 This would make the cost of a pound of digestible dry matter in the 

 beets 1.01 cents ami in the silage 0.71 cent. 



Profit and loss. — The following estimate of the relative cost of the 

 feed for the alternating lots A aud B during nine weeks in the experi- 

 ment of 1890, and for the alternating lots and D during eight weeks 

 in the experiment of 18S9, is based on clover hay at $9, bran at $13, 

 silage at $2.30, and beets at $2 per ton :

No accouut i.s taken of the silage refused, which amounted to about 10 per cent of 

 the total amount fed, because the refuse was of no further value as feed. In the case 

 of the hay, however, it was the aim in both experiments to ofter more than wouhl be 

 eaten ; hence only that actually eaten is calculated. * * * [In the experiment of 

 1890] the increase of live weight apparently due to the beets, added to the increase 

 of milk, would amply justify the increased cost of feed; but in last year's experi- 

 ment [1889], the increase of live weight was greatest with the silage ; hence we are 

 in doubt whether the difference this year may not be due to an inferior quality of 

 silage [it being made from less mature corn and containing a smaller proportion of 

 grain than the corn nsed in 1889]. 



The authors conclude that before beets and silage can safely be 

 compared on the basis of their digestible dry matter it must first be 

 conclusively demonstrated that the increase in live weight in 1800 ap- 

 parently due to beets was in reality due to this cause and was not 

 merely accidental.
