This plan provides for no money crop to be sold from the farm, 
but is adapted to make a more finished product from the stable 
the source of income. This seems to be the true course for a 
large class of our farmers. A point which may be graphically 
illustrated by a diagram * showing at a glance a comparison of the 
fertilizing elements (nitrogen, phosphoric acid and potash) removed 
from the farm in one ton of each kind of produce named. The 
average price of each is given in the table, with the value of the 
fertilizing elements, as well as what is left after subtracting fertil- 
izing value removed. The remainder represents cost of seed, 
interest, taxes, labor, and last of all, profits. 
* Authorities consulted in making up the table from which the diagram 
was constructed were: 
Warrington’s Chemistry of the Farm. 
Ladd: N. Y. Agricultural Experiment Station Reports and Bulletin 
14, new series. 
Koenig’s Food Tables. 
Watt’s Chemical Dictionary. 
Wolf's Tables, K 
Johnson’s How Crops Grow, Eng. ed. 
The prices at which the fertilizing elements have been calculated are: 
17 cents per pound for nitrogen. 
6 os tf 43 phosphoric acid. 
4.5 “ * ‘ potash.
