Or, stated in another way, the cows in the four groups fed 

 upon normal rations during periods 2 and 3 gave three and 

 eight tenths per cent less milk per day during period 3 than 

 during period 3, while the two cows in group 3 fed upon what 

 ought to be considered an abnormal ration gave during period 

 3 fourteen and one tenth per cent less milk during period 3 than 

 during period 3. If the two cows in group 3 had shrunk in 

 the same proportion as the cows in the other four groups, 

 their shrinkage would have been 1. 19 pounds, leaving a short- 

 age of 3.24 pounds, or a quart and a half of milk per cow 

 directly chargeable to wrong feeding. We do not wish in 

 this connection to be understood as condemning corn meal as 

 a dairy food. It is a very valuable food when fed in connec- 

 tion with fodders rich in albuminoids, as clover hay, such 

 grains as peas and oats or the highly nitrogenous by-fodders, 

 cotton-seed, linseed, and gluten meals; but to make it the 

 chief grain food with coarse fodders furnishing ample sup- 

 plies of non-albuminoids but deficient in albuminoids, is 

 simply inexcusable. 



Coming now to group 4, we find the changes to have been 

 to oat hay in period 3, in 23eriod 3 oat ha}' is replaced by 

 clover hay, and in period 4 they returned to the original 

 ration. Table 4 shows the results from these changes.
