An examination of the yields of the different crops shows that the 

 dissolved bone black has given, with the majority of them, the 

 largest return and the Caribbean sea guano the least. 



With peas and turnips South Carolina rock seems to have been 

 more effective than dissolved bone black. This point is brought 

 out quite sharply. The fact that turnips respond to manuring, with 

 some crude phosphate, has been noted by other experimenters. 



The results obtained in this experiment with South Carolina rock 

 on peas agree very closely with the results obtained from all other 

 experiments made by the Station covering this point. 



Box or pot experiments upon this subject have been in progress 

 at the Maine Station for some years. This work was started by 

 Prof. Walter Balantine and continued by him until his death; since 

 that time the work has been continued by Prof. L. H. Merrill. The 

 first report upon the subject was made in the annual report for 1893, 

 and the last reported up to this time is in the report for 1898, page 64. 

 The following description of the plan of the experiment and the 

 results obtained are copied from the Fourteenth Annual Report of 

 the Maine Station, pages 66 to 74: 



PHOSPHATES USED IN BOX EXPERIMENTS. 



In the experiments here recorded, three forms of phosphates were 

 used.
