nm DS LUDY OF RATIONS FED TO MILCH COWS. 49 
Samples of the different feeding stuffs used in the test were 
taken early in each test and sent to the laboratory for analysis. 
As soon as it was possible to obtain the results of the analyses, 
the ration fed was calculated and suggestions were made for 
changes in the ration. After changes had been made and the 
animals had been upon the new ration for a week or longer, 
the herd was again visited and a new twelve-days’ test was 
made. 
The prices of feeding stuffs which are used in calculating cost 
of the rations fed were current in December, 1893. The manu- 
tial value is based upon figures given in the Report of the Massa- 
chusetts Agricultural Experiment Station for 1893, pp. 358-365. 
The nitrogen in the feeding stuff is counted as worth 17% cents, 
the phosphoric acid at 5 cents, and the potash at 5% cents per 
pound for manure, and it is assumed that 85 per cent. of the 
quantities in the food may be saved in the manure. Unfortu- 
nately most farmers care for manure so poorly that a much 
smaller percentage is usually saved.

A dairy farm was visited by a Station representative December 
4-16, 1893, and after an interval of four weeks it was again vis- 
ited (January 15-27). There were 19 cows in each test, but four 
of them were changed between the two tests.
