per week for his own use and sold the balance of his cream for 

 $536 during the nine months. 



I. F. Given kept five cows, the cream from which brought 

 .$276. 



The town farm sold from seventeen very common cows 

 $742 worth of cream. 



If these parties had as much cream during the remaining 

 three months of the year as they had in March and November, 

 or at that rate, they would have had $90 a piece for the cream 

 from Jersey cows and $75 each for the commonest kind of cows. 



C. D. Sage, of North Brookfield, averaged 14 spaces on each 

 Cooley can, of seventeen quarts of milk, from grade Jerseys 

 during the first eleven months of 1886. The average price paid 

 per space during that time was 3.52 so that Mr. Sage received 

 $49.28 for the cream from seventeen quarts of milk, besides 

 having the skimmed milk left; this is equal to 140.80 per 

 100 pounds of milk during the eleven months. Skimmed milk 

 divested of every particle of butter fat, contains 10 per cent, ol 

 plant food, made up of lime, magnesia, nitrogen, phosphoric 

 acid, potash, and other oubstances which have their place in 

 the vegetable economy, as against 12 or 13 per cent, in full milk. 

 Now take it for granted that no dairyman should be satisfied 

 with a less yield of milk from each cow kept on the farm than 

 5,000 per annum, which is equivalent to 500 pounds of plant 

 food contained in the skimmed milk of an average cow for one 

 year; multiply this amount by the number of cows in the herd 

 and you have the annual drain upon your land from this source, 

 where the milk is sold from the farm. Continue this process 

 of depletion for series of years and you can no longer wonder 

 at the exhausted condition of the soil. The fact is selling the 

 milk is equivalent to selling the fertility of the land.
