168 AMERICAN DAIRYING. 



average weight of fat unaccounted for daily 

 was Jersey 0.35, Guernsey 0.37 and Short-horn 

 0.38 lb. These weights of fat were for the 

 Jersey 0.9, Guernsey 1.2 and Short-horn 1.4 per 

 cent of the total weight of fat produced daily 

 during the ninety-day test, or for the Jersey 

 0.043, Guernsey 0.054 and Short-horn 0.052 per 

 cent of the milk produced per day in the ninety- 

 day test. 



Considering the great difficulty of getting a 

 fair sample of forty pounds or more of butter, 

 the analysis of which must come into every 

 one of these 360 accounts, and the fact that the 

 fat is measured in the test bottles instead of 

 weighed, these results show very close work, 

 not onlj'' by all the men connected with the 

 Columbian dairy test but also by the Babcock 

 milk test.
