of soda 160 pounds, equivalent to 25 pounds of nitrogen; dis- 

 solved bone-black 320 pounds, equivalent to 53 pounds of phos- 

 phoric acid; muriate of potash 160 pounds, equivalent to 82 

 pounds of potash. These are applied singly, two by two, and. 

 all three together, thus making seven different kinds of fer- 

 tilizers, the combination of the three being a so-called ' ' com- 

 plete" fertilizer. On an eighth plot a moderate quantity of 

 stable manure with some phosphoric acid in addition was ap- 

 plied, and on a ninth a liberal quantity of stable manure alone. 

 Three other plots in the group are left unmanured.
