Oct. 12th aud 13th, and husked Oct. 23d and 24th. A slight mis- 

 take was made in arrangement, four rows being put in each plot, one 

 on either edge, and none in the space between the plots. This, while 

 not vitiating the work to any great extent, makes the apparent 

 Increase due to the fertilizers less than the reality, because the out- 

 side rows in each plot were not fully under the influence of the 

 materials supplied. 



In July the plots which had received potash appeared to be doing 

 distinctly better than the others, my assistant rating them in the 

 order of excellence 13, 10, 7, 9, and 5, with the others considerably 

 poorer. There was a considerable difference in the quality of the 

 soil in the nothing plots; but this, as will be seen, affected chiefly 

 the standing of the plot where manure was used.

Average of Measurements. 



These figures make evident the substantial accuracy of the judg- 

 ment recorded above. The plot receiving nitrate of soda alone does 

 not appear to retain its early supremacy over the nearest nothing ; 

 but the falling off is not serious as compared with most of the other 

 plots. I do not feel warranted in concluding that it would have been 

 better to apply this chemical in fractional dressings.
