 either not turned out at all or for about half an hour only. 

 The cows were all ordinary shorthorns and fairly represent- 

 ative of the herd of over fifty cows.

 MILK OF TWELVE COWS (CALCULATED). 



Mixed milk. More milk was produced in the first milking 

 than in the last two taken together. The solids not fat 

 tended to increase during the day ; and the fat percentage was 

 much higher (nearly 1 per cent.) at mid-day than in the morn- 

 ing, but not higher for the third milking than for the second, 

 though the interval before the third is three hours less, and 

 the quantity is less at this time. The cows, however, were not 

 milked so clean in the evening, and this probably explains the 

 results. Had a third milking not been done each day it is 

 probable that the morning's milk would have occasionally con- 

 tained less than the standard of fat. In. no case did the fat 

 or solids not fat fall below the standard, but the fat varied 

 considerably within a fortnight in some cases. 



Individual milk. The milk of the individual cows showed 

 great variation. Two hundred and sixteen tests were made, 

 with the following results :
