It seems to be scarcely necessary to add that the above 

 estimates refer only to the cost of feed and of the cow, and 

 do not include cost of labor, housing, interest and risk of 

 life of animal, etc. 



6. Some Conclusions suggested hy the Preceding Finan- 

 cial Record. 



1. The total value received above net cost of feed and of 

 cow does in no instance exceed 15.97 cents per day; its 

 average in eleven cases is 13,02 cents. There is an actual 

 loss of 1.2 cents per day in one case (No. 8), where the 

 average daily yield of milk for the entire period of observa- 

 tion (331 days) is as low as 7.7 quarts. 



2. The total value received above net cost of feed and of 

 cow consists in every instance in a controlling degree on the 

 manure obtainable. In No. 8 it prevents a serious loss, 

 while in No. 4 it represents practically the entire gain; in 

 some instances it amounts to from three-fourths to two- 

 thirds (Nos. 12 and 3), and in none as low as one-half of the 

 total value secured. 



3. As the value of the manure depends in a controlling 

 deijree on the amount of fertilizino- constituents contained in 

 the feed, it becomes apparent that this point ought to be 

 seriously considered when selecting suitable fodder articles 

 for a remunerative daily diet of dairy cows. The table con- 

 taining the valuation of the essential fertilizing constituents 

 of the fodder articles used in our experiments is very sug-
