6. SOME CONCLUSIONS DRAWN FROM THE PRECED- 

 ING RECORDS. 



1. Tlie relative proportion of digestible uitrogenous aud uon- 

 uitrogeiious constituents consumed differs on the whole in a larger 

 degree during the year of 1887 than in 1888. During one-half of 

 the year 1887 it ranged above 1 :8.5, while during the year 1888 it 

 reached 1 :7.3 in only one case ; and for six of the remaining months 

 it was below 1 :6 (nutritive ratio). 



2. The amount of fat in the milk varied during the year of 1887 

 from 3.45 to 4.50 per cent, with an average of 4.00 per cent., while 

 d.iiing the year of 1888 it varied from 3.14 to 4.86 per cent, with an 

 average of 3.i)7 per cent. 



3. The quantity of milk, in quarts, required to produce one space 

 of cream during the year of 1887 varied from 2.12 to 1.63 and 

 amounted on the average, to 1.93 quarts, for the entire year; during 

 the year of 1888 it varied from l.'J3 to 1.43, while it averaged for 

 the year 1.72 quarts. 



4. The value received for one space of cream during the year 

 of 1887 varied from 3.00 to 3.88 cents with an average of 3.58 cents ; 

 during the year of 1888 from 3.25 to 4.00 cents were received for 

 each space, with an average of 3.72 cents, which would equal 12.17 

 cents per quart of cream for 1887 and 12.65 cents for 1888. 



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

 cpiart of cream amounted for the year 1887 to 15.0!J cents and for 

 the year 1888 to 13.55 cents. 



6. The value of the fertilizing constituents which are lost to the 

 farm by the sale of cream produced amounted, during both years.
