It will be noticed from the results of these experiments given in 

 Table I., dissolved bone black, with potash and ammonia salts, 

 give the highest yield of grain, fine ground bone standing next, 

 while fine ground South Carolina rock and stable manure produce 

 about the same results. In 1888, without the further addition of 

 manure, the stable manure stands far ahead of the others in its 

 yield of hay, while the fine ground bone stands next.
