 An outline of the plan and object of this experiment is 

 quoted from the sixteenth annnal report : — 



In this exi:)eriment, which has eontinued since 1893, the purpose is 

 to test a system of using- manures in rotation for the production of 

 grass. The area used in the exjieriment is about 9 acres. It is d^ivided 

 into three approximately equal plots. The plan is to apply to each 

 plot, one year barnyard manure, the next year wood ashes, and the 

 third year fine-ground bone and muriate of potash. As we have three 

 plots, the system of manuring has been so arranged that every year we 

 have a plot ilhistrating the results of each of the applications under 

 trial. The rates at which the several manures are employed are as fol- 

 lows : barnyard manure, 8 tons ; wood ashes, 1 ton ; ground bone, 600 

 pounds; and muriate of potash, 200 pounds per acre. The manure is 

 always applied in the fall ; ashes and the bone and potash in early 

 spring. 



The past year brought the fifth successive season unfavor- 

 able to hay production. The rain fall in May was slightly 

 above the normal, but the following month was one of the 

 driest Junes recorded since records have been kept here at the 

 college. 



The yield obtained this year on the different systems of 

 manuring is shown in the followine: table : — 



' Owing to the difficulty of .securing good wood a.«hes a mixture of sl.'jg and muriate of potash, 

 supplying the same amount of pkosphoric acid and potash, was substituted this year.
