FARM DAIRYING 



A study of the following table explains why 

 poor run-out farms are built up by dairying. The 

 figures show the amount of money received for 

 the products sold, and the value of the fertilizing 

 constituents removed from the farm, based on 

 nitrogen being worth 12 cent per pound, phos- 

 phoric acid 4^ cents, and potash 4^ cents.
