Relative Yield of Corn and Millet^ in Percentages. 



It will be seen that the two halves of the several plots 

 Avere not quite even in fertility, as indicated by the yields 

 of the first year, at the start. The greatest difference was 

 found on plot 3. The north half of this plot suffers from 

 spring or ooze water to a greater extent than the south part. 

 AVe must be cautious, therefore, in attaching importance to 

 the largely increased difference in yield on that half of this 

 plot manured in spring for the past season. It wdll be 

 noticed, however, that, while there are differences in the 

 degi'ee, there is a marked tendency to increased superiority 

 in favor of spring application on the other plots of the field 

 as Avell as on this. 



This experiment will be continued 5 but it has seemed 

 wise to call attention to the results so far obtained, for the 

 reason that the conditions on this field as resfards the nature 

 of the surface are similar to those existing in the fields on 

 many farms, and for the further reason that the results cer- 

 tainly indicate that there is grave reason to doubt whether 

 application of fresh manure during the winter and allowing 

 it to lie upon the surface until spring is wise. In conclu- 

 sion, I should perhaps call attention to the fact that, while 

 the difterence between the south and the north half of plot 3 

 may be to a considerable degree due to the diflerent natural 

 conditions, it seems only reasonable to conclude that it wyaj 

 be in part also due to the fact that the fertility of this jdot 

 at the start was much lower than that of the others, as it
