1 and 3, showing an apparent influence of the greater amount 

 of potash used on these plots in a larger proportion of clover. 

 For the present season the fertilizers were applied as last 

 year, being evenly broadcasted on April 1 1 . The first crop 

 was cut June 21. It consisted largely of red-top, which 

 was then not fully in bloom. The second crop was cut 

 August 26. Both crops were well secured, and the yields 

 are shown Ijelow : —

AVe have then, as will be seen, an average product, from 

 the application richer in nitrogen and phosphoric acid, at the 

 rate of 150 pounds of hay and 80 pounds of rowen per acre 

 more than from the application poorer in these elements and 

 richer in potash. It is believed that the failure of plots 2 

 and 4 to show greatly superior development of clover is in 

 part due to variations in physical characteristics of the soil 

 of the dift'erent plots, leading to unfavorable moisture con- 

 ditions, which prevented an even catch of clover on plots 2, 

 3 and 4, but did not injuriously att'ect Plot 1. Further, it 

 should be pointed out that results which will be published 

 later in this rejiort in the case of clover experiments on a 

 series of plots manured alternately with muriate of potash 

 and with sulphate of potash indicate that the long-continued 

 use of muriate of potash in liberal amounts without liming is 

 unfavorable to the healthy development of clover. This 

 field has now been broken up, and will be again put into 

 corn next season.
