Report op the Chemist of the 



(5) In October 39 herds produced more cheese than in Septem- 

 ber from 100 pounds of milk by amounts varying from 0.08 to 

 1.94 pounds; while only one herd produced less. There was a 

 general average increased yield of cheese amounting to 0.81 pound 

 for 100 pounds of milk. 



It will be interesting to notice more in detail to what changes 

 in the composition of milk the variations in the yield of cheese 

 were due from month to month. In the subjoined table, we 

 indicate by plus and minus signs the amount of increase or de- 

 crease of fat, casein and cheese for 100 pounds of milk for each 

 month compared with the preceding month.

In June we see that there was a slight increase of fat but a 

 much larger decrease of casein so that the general result was 

 a decrease in yield of cheese. The same was true in July. In 

 August the fat increased largely and the casein slightly. In 

 September, while the fat decreased somewhat, the casein in- 

 creased enough to counterbalance the loss of fat and add to the 

 yield of cheese 0.44 pound for 100 pounds of milk. In October 

 both fat and casein increased and the relative cheese yield in- 

 creased correspondingly.
