the next year wood ashes, and the third year fine-ground bone 

 and muriate of potash. As we have tliree plots, the system of 

 manuring has been so arranged that every year we have a plot 

 illustrating the results of each of the applications under trial. 

 The rates at Avhich the several manures are employed are as 

 follows: barnyard manure, 8 tons; wood ashes, 1 ton; ground 

 bone, 600 pounds; and muriate of potash, 200 pounds, j^er 

 acre. The manure is always applied in the fall; ashes and the 

 bone and potash in early spring. 



The past .season has been rather unfavorable for the pro- 

 duction of large yields of hay, as there was a considerable 

 deficiency in both spring and summer rainfall. The yields 

 of hay and rowen and the total yields for each system of 

 manuring were at the following rates per acre : —

The average yield of the entire area this year was 4,840 

 pounds per acre. The average yield of the entire area from 

 1893 to 1904, inclusive, has been 6,718 pounds per acre. , 

 The average yield from 1893 to 1905, inclusive, has been 

 6,479 pounds per acre. The average yields under the 

 different systems of top-dressing have been as follows : —

 When top-dressed with wood ashes, . 

 When top-dressed with bone and potash,

It will be noticed that the average yields of the entire 

 area for this year are much below similar averages for the 

 period. 



VIII. — Nitrate of Soda for Rowen. 

 For the past five years we have been experimenting in 

 one of our fields for the purpose of determining whether 

 nitrate of soda applied soon after the first crop is cut will
