The experiment has now been in progress nine years, and 

 during seven of these years corn has been grown ; on all 

 plots five years and on two only of the plots two years. 

 The averages for the seven years are given in the table : — 



During two years one-half this field was occupied by 

 Japanese millet (^Panicmn Italicum). The average yields 

 per year are shown in the table : — 



It will be seen, then, that thus far the two systems of 

 manuring stand nearly upon an equality. The fertilizer 

 poorer in potash ("special") has given the more corn and 

 the more hay. The other fertilizer, richer in potash, has 

 given the more corn stover, rowen, millet seed and millet 

 straw. At present the two stand practically equal, as shown 

 by the corn crop of the past season. It is believed that by 

 the frequent introduction of clover (of which we have not 

 yet had a good catch) the fertilizer richer in potash will 

 prove superior to the other.

 Various Crops. (Field B.) 

 This experiment has been in progress in its present essen- 

 tial features since 1893. From 1884 to 1889 the odd num- 

 bered plots, 11 to 21, were manured yearly at the rate of 

 200 pounds per acre of muriate of potash, while the even
