the rate of 6 cords per acre, with the following exceptions. 

 No manure was applied in 1897, 1902 and 1905, and in 

 1898 the amount applied was at the rate of 4 cords per acre. 

 The reason for the omission of manure in the years men- 

 tioned and for the smaller amount in 1898 was that experi- 

 ence indicated that its application would cause the grass and 

 clover to lodge badly. 



Manure has been applied to plots 2 and 4 as follows: in 

 1891 and 1892, at the rate of 3 cords per acre; in 1898, at 

 the rate of 2 cords per acre; while in 1897, 1902 and 1905 

 no manure was applied. In all other years the applica- 

 tion has been at the rate of 4 cords per acre. Potash has 

 been applied to jDlots 2 and 4 at the rate of IGO pounds per 

 acre of high-grade sulfate annually, except in the years when 

 no manure was applied. In these years the j)otash also was 

 withheld. 



The entire field was limed in 1900, at the rate of 1 ton 

 per acre. The manure applied has been that made by well-fed 

 milch cows, and carefully preserved. It has usually weighed 

 about 3 tons per cord. Both manure and fertilizer have been 

 applied broadcast after plowing, and harrowed in. 



The crop of the past season was mixed grass and clover, 

 this being the second year, as above indicated. The manure 

 was applied with a spreader on May 2. The high-grade sul- 

 fate was applied broadcast by hand, and this year, by mis- 

 take, it was applied to plots 1 and 3 as well as to plots 2 

 and 4. 



The following tables show the rates of yield on the several 

 plots and the averages under the two systems of manuring : —
