to 1,500 pounds on Plot 24. The yields upon plots 20 and 

 22 were 395 and 640 pounds per acre respectively. 



The first year of the experiment, upon Plot 18 stable 

 manure, for some unknown reason, was not applied in 

 preparation for the corn crop, but in its stead the following 

 fornuila was used broadcast, viz. : — 



Pounds per Acre. 



Nitrate of soda 300 



Acid phosphate, ....... 450 



Muriate of potash, . . . . . .120 



Plot 20 was introduced into the rotation the same year as 

 Plot 18, but it began with potatoes instead of with Indian 

 corn. 



Since Plot 22 was to begin the rotation with Indian corn 

 in 1894 so as to follow one year behind Plot 18, and in view 

 of the fact that winter rye had not been sown in the autumn 

 of 1892, spring rye was sown with common red clover seed 

 in the spring of 1893. In view of the exhausted condition 

 of the soil, the following fornmla was applied before the rye 

 and clover seed were sown, viz. : — 



Pounds per Acre. 



Nitrate of soda, ....... 300 



Acid jjliosphate, ....... 240 



Fine-ground bone, ...... 180 



Muriate of potash, . . , . . .120 



The rye seed was evidently poor, for it is recorded that 

 the crop was a failure. The clover also failed in 1894, 

 owing, as has since been learned, to the acidity of the soil 

 which had not yet been corrected by the use of lime. This 

 failure of the rj^e and clover was unfortunate, in view of the 

 fact that the year 1894 was the beginning of the actual 

 rotation. 



In 1895 the plot was devoted to Indian corn, and from 

 that time forward proceeded according to the regular plan. 



Plot 24 should, according to the scheme of rotation, have 

 been occupied by common red clover in 1893 ; but, as this 

 was impossible, it Avas manured with the following mate-
