indicated by the nearly equal yields of all the nothing plots, appears 

 to have been of quite uniform quality throughout. 



The manure used in this experiment was not sampled for analysis, 

 neither were weather observations taken. In other respects, the 

 experiment was conducted precisely as are those immediately under 

 my control ; and the work appears to have been very faithfully 

 executed throughout. There was practically no soft corn in the 

 field, and all was weighed together.

These figures show that the potash plots early showed a superiority 

 which the harvest proved them to have fully maintained.
