From four to five pounds of alsike clover per acre were added 

 by broadcast seeding early in the succeeding spring (1889). The 

 seed came up well, and suffered but here and there in wet spots 

 during the first winter. Barren spots were reseeded. The entire 

 meadow was cut but once during the first summer season, some- 

 what later than usual ; the majority of grasses did not, as might 

 be expected, head out. 



As soon as the first crop of hay was secured, a system of ma- 

 nuring was planned, to show the comparative manurial effect of 

 top-dressing, as follows : by barn-yard manure ; by ground bone 

 and muriate of potash ; by unleached wood ashes. From 1889 to 

 1893 the quantity of barn-yard manure was gradually reduced, to 

 ascertain how far different quantities used per acre would affect 

 the final results. Since 1893 each plat has received in succession 

 annually the same quantity of one of the different kinds of manure, 

 to try a rotation of manures iqion permanent grass lands. The 

 annual yield of hay on the different plats is stated below : —
