The amount of nutrients consumed in each period and the yields of 

 milk and of fat are tabulated. 



Lot 1 , which received corn fodder first, gave practically the same 

 yield of milk aud of fat in both periods; but lot 2, which received silage 

 first, showed a marked falling off in yield of both milk and fat in the 

 dried fodder period. Combining the yields of the 2 lots on silage and 

 on dried corn fodder to neutralize any effect of advancing lactation 

 gives the following:

"It will be observed that, although the total amount of dry matter 

 furnished by each ration was practically identical, the yield of milk 

 from the silage ration is 258.3 lbs., or 12.8 jier cent, greater than that 

 from the dried fodder ration for the same cows for a like period; aud 

 the yield of butter fat is 8.13 lbs. greater, or 10.4 per cent." 



About 6.8 per cent more dry matter was consumed on the silage 

 rations than on the dried fodder rations. The animals gained about 

 200 lbs. on the silage. The results of the experiments are summarized 

 as follows: 



"(1) The cost of harvesting, storing, and preparing tin- dry matter contained in 

 corn was greater in the form of silage than in the form of dried fodder. 



"(2) The changes that occur in the composition of silage were not snch as to 

 decrease its feeding value in a greater degree than those which occur in the process 

 of curing corn fodder; and the losses due to spoiling in the silo amounted to 4 per 

 cent of the total amount stored. 



"(3) For milk and butter production the feeding value of the dry matter of the 

 silage was greater than that of the dried fodder corn. The yield of milk was 12.8 

 per cent greater and the yield of fat 10.4 per cent greater." 



On the basis of these experiments it is estimated that about $10 per 

 acre more would be realized for corn fodder when preserved and fed in 

 the form of silage than as dried fodder. 



Further experiments in cream ripening — flavor, aroma, acid, 

 H. W. Conn {Connecticut Storrs Sta. Rpt. 1896, pp. 17-43). — As showing 

 the variation in the number and character of the bacteria at different 

 times a series of experiments with 8 cows are reported in which the 

 milk of each cow was examined for bacteria at different intervals. 

 There was found to be a great difference in the number of bacteria 

 from different cows at the same time and also great variety in the 

 bacterial flora at different times. No 2 of the samples from the first
