$18, and ground flaxseed at $60, perton. All hay was rated at 
$10 per ton, corn silage at $3, roots at $3, and all green forage at 
$2 perton:. It is thought better to assume the one valuation for 
any food throughout all the trials, which extended over portions 
__ of four seasons, than to attempt to follow fluctuations of market 
price. Enough data are given to allow of recalculation, by any 
who desire, of the cost of rations at other prices for foods than 
those just stated. All forage has been placed at the same valua- 
tion per ton. The cost of production per ton of corn forage will 
hardly be the same as for oat-and-pea forage, etc. There is more 
fabor necessary to establish a good stand of alfalfa than for the 
sowing of the oats and peas or similar crops, but after alfalfa is 
once established it will furnish three or more cuttings each season 
with little more labor expense than that .f harvesting the crop. 
_ Not enough data are available, at present, however, to warrant 
us in fixing certain different cost valuations per ton. 
Table I gives the results obtained in feeding 14 cows from 
May 15 to July 15,1891. The average age of these cows was 
on June 1, three years, and they had been in milk on the 
average 6.8 months at the beginning of this feeding trial. 
From: May 16 to May 81 inclusive, corn silage was fed in 
_ the morning and at noon, mixed hay, clover and timothy, at 
night and a mixed grain (No. 16) consisting of six parts wheat 
bran, three parts corn meal, and two parts linseed meal, O. P. 
_ The grain represerted 48.6 per cent. of the cost of the ration and 
supplied 39.7 per cent. of the total digestible nutrients. The 
silage represented 30.0 per cent. of the cost of the ration and sup- 
plied 35.8 per cent. of the digestible nutrients. 3 
From June 1 to June 15, inclusive, corn silage was fed in 
the morning, alfalfa forage at noon and mixed hay at night. The 
grain fed (No. 17) consisted of four parts wheat bran, four parts 
_ ground oats, five parts corn meal, and two parts gluten meal. 
_ The grain represented 52.4 per cent. of the cost of the ration and 
_ supplied 38.3 per cent. of the digestible nutrients. The silage 
and forage represented 24.6 per cent. of the cost of the ration 
and supplied 27.7 per cent. of the digestible nutrients. 
i. From June 16 to June 30, inclusive, alfalfa forage was fed 
_ morning and noon. and hay at night. The same grain was fed as 
io in the preceding period. The grain represented 54.5 per cent. of
