EXPERIMENTS WITH MANURES. 



W. G. WYMAN'S STATEMENT. 

 My experiment field contains one acre and thirty-two 

 square rods, divided into six equal parts of one-fifth of 

 an acre each. The soil is a heavy loam upon a clay 

 sub-soil ; is moist and retentive of manures. The crop 

 of 1859 was grass. No manure has been applied during 

 three years previous to 1860. It was first plowed 

 about seven inches deep ; on the 12th of May, after a 

 fine growth of grass had started, which was turned under 

 with a swivel-plow. Five cords of stable manure from 

 a barn cellar, made with horses, cows and hogs, one 

 cord by accurate measure to each lot, 500 lbs. Coe*s 

 ground bone, 100 lbs. to each lot, and 250 lbs. Coe's 

 superphosphate of lime, 50 lbs. to each lot was applied, 

 and the field planted, May 23d, with common yellow 

 corn, with a corn planter, in rows three feet three inches 

 apart each way. It was cultivated with a horse-hoe 

 four times each way, and with a hand-hoe twice, and 

 harvested Nos. 2, 3, 4 and 5, October 29th, and Nos. 

 1 and 6 November 5th, and the whole product of each 

 plot weighed as follows, viz : 



No. 1 produced 879 lbs. sound ears corn, 11 lbs. soft, and 1100 lbs. stover
