rowed in. Daring the pa«t season the .sani«^ halves of all the 

 plots have onee more been limed, and at practieally the same 

 rate as before ; but this year, as the land was in grass, the 

 lime was applied as a top-dressing on the grass in spring. 

 The date of application was May 13. The crops grown in 

 this field, in the order of succession, beginning in 181)0, 

 have been : potatoes, corn, soy beans, oats, grass and clover, 

 grass and clover, cabbages and ruta-baga turnips, potatoes, 

 onions for four years (1898 to 1901 inclusive), potatoes, 

 grass and clover, and grass and clover. The field was sown 

 to grass and clover after the harvesting of potatoes in the 

 autumn of 1902 (September 15). The rate of seeding per 

 acre was : timothy, 18 pounds ; red- top, 8 pounds ; red 

 clover, 5 pounds ; and alsike clover, 4 pounds. The clover 

 winter-killed, and accordingly additional clover seed (15 

 pounds) was sown on April 4, 1903. 



On account of the deficiency in rainfall from the middle 

 of April to about the 10th of June, 1903, the yields last 

 year on all plots were very small. The yields during the 

 past season have been much larger. They are shown in the 

 following table : —
