difference in the system of manuring. We knoAV that the 

 plants in the field, on account of imperfect germination due 

 to the unfavorable weather which preceded and followed 

 planting, were not as thick as is desirable, Tlic fact, how- 

 ever, that the yield of stover on Plot 4 is greater than that 

 on Plot 3, renders it exceedingly doubtful whether the cause 

 of the relatively small yield of corn on Plot 4 was the greater 

 proportion of unoccupied space. 



VIII. — Experiment in Manuring Grass Land. 

 The report which is to be made concerning results in this 

 experiment is best introduced by quoting from my sixteenth 

 annual report : — 



In this experiment, which has continued since 181)3, the pur- 

 jiose is to test a system of using manures in rotation for the 

 production of grass. The area used in the experiment is about 

 nine acres. It is divided 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 

 illustrating the results of each of the applications under trial. 

 The rates at which 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, per 

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

 bone and potash in early spring. 



The past season was exceptionally favorable for the pro- 

 duction of a heavy yield of hay, but a relative deficiency in 

 rainfall during the period occupied by the growth of the 

 rowen crop was doubtless the principal reason for the falling 

 off in the yield of rowen, as compared with that produced in 

 the season of 1903. The yields of hay and rowen and the 

 total yields for each system of manuring were at the follow- 

 ing rates per acre : —
