5. The total cost of feed consumed for the production of 

 one quart of cream amounted for the year 1887 to 15.09 

 cents, for the year 1888 to 13.55 cents, and for the year 

 1889 the same as in 1888. 



6. The value of fertilizing constituents which are lost to 

 the farm by the sale of cream produced, amounted, accord- 

 ing to the analyses of our cream, during the year 1887 to 

 3.09 per cent., during 1888 to 3.65 per cent., and in 1889 

 to 3.03 per cent., of the total fertilizing value of the feed. 

 From these figures it will be seen that in selling the cream 

 from the farm much less fertilizing constituents are lost to 

 the farm than in selling the whole milk. A loss of twenty 

 per cent, of the fertilizing constituents contained in the feed 

 has been allowed in our previous publications, when selling 

 the whole milk. The statement of net cost of feed, as com- 

 pared Avith that of its total cost, refers to the original cost of 

 the feed less the value of fertilizing constituents obtainable 

 in manure. 



7. The net cost of feed consumed per quart of cream 

 (1 quart =: 3.4 spaces) averaged, for the year 1887, 8 cents ; 

 for the year 1888, 6.47 cents, and for the year 1889, 6.4 

 cents. As we obtained 12.17 cents per quart of cream dur- 

 ing 1887, 12.65 cents during 1888, and 11.5 cents in 1889, 

 we secured a profit above net cost of feed of 4.17 cents per 

 quart in 1887; in the year 1888, 6.18 cents; and in 1889, 

 5.1 cents, for the same quantity. 



8. We produced, during the year 1887, 1,752.2 quarts 

 of whole milk per month; during the year 1888, 1,662.2 

 quarts; and in 1889, 1,862.3 quarts. It required, on an 

 average, 6.51 quarts of whole milk to produce one quart of 

 cream during 1887, 5.83 quarts during 1888, and 5.64 quarts 

 during 1889. We secured, on an average per month during 

 1887, 1 ,482.9 quarts of skim-milk and 269.3 quarts of cream ; 

 in 1888, 1,380.4 quarts of skim-milk and 285.8 quarts of 

 cream ; and in 1889, 1,531.9 quarts of skim-milk and 330.4 

 quarts of cream. 



9. Counting the Avhole milk at three cents per quart, 

 then skim-milk has cost us, on an average, during the year 

 1887, 1.32 cents per quart; during the year 1888, 1.00 cent 

 per quart ; and in 188;", 1.14 cents per quart. The cost of
