the north end of the field, where the oats had been raised 

 during the preceding season, and the oats were raised at the 

 south end of the field, the part previously occupied by the 

 corn. The oats were cut for hay when well headed out, and 

 the corn when fully matured, for grain and stover.

Conclusions. 



The difference in the yield of oats and corn for two suc- 

 ceeding seasons points in the same direction ; namely, phos- 

 phatie slag used in connection with nitrate of soda is a very 

 efficient substitute for ground bone. To what extent these 

 results, in our case, have to be ascribed to the presence of 

 an excess of lime in the phosphatie slag, as compared with 

 ground bone, is to be determined by a future actual trial.
