acre of newly plowed land in the same time (see " Tlie Soil," by King, 

 pp. 155^ 189) — tl'en we may readily understand how the moisture 

 tliat was conserved by early plowing might result in an increase of 

 crop of TO per cent above that grown on the late plowed land. 



Result of deeper ])lanting and level tillage. — 



Robert Call, Genesee Co. Soil deep sandy loam with sandy sub- 

 soil. A clover and timothy sod dressed with a light application of 

 stable manure and j^lowed seven inches deep just before planting, 

 June 8th. Rolled and harrow^ed three times, marked two feet ten 

 inches each way. Covered with a common potato coverer, leaving 

 a ridge over the rows. On the special plat a one-horse plow was used 

 to make furrows deeper one way. After a few days the ridges were 

 scraped off level. Both plats received three or four cultivations. 

 The only difference in treatment was in depth of planting and that 

 wliile the field was hilled at the last working the special area was 

 left level. 



The result was that the shallow planting and hilling yielded 132 

 bushels per acre, while the deeper planting and no hilling yielded 156 

 bushels. 



Area of special plat, one-eighth of an acre. Mr. Call writes 

 " Shall try a larger piece next year." 



Shallow 2ylanting and hilling vs. deep planting and level culture. 



Geo. W. Pierce, Ontario Co. Soil a dark loam — planted June 

 11. One plat was marked shallow, seed covered with plow and 

 hilled at last cultivation. The other plat was furrowed deeply, 

 covered with plow and left level at last cultivation. 



Result : The shallow planted and hilled plat yielded at the rate of 74 

 bushels per acre, while the deep planted and level tilled yielded 107 1-2 

 bushels, a difference of 33 1 -2 bushels in favor of the latter. 



From report of R. E. Barden, Tioga Co. Soil a loam with clay 

 or rock subsoil — plowed al)Out seven inches deep. Part was marked 

 with a corn marker three or four inches deep — seed covered with 

 a cultivator, worked five times — hilled. Another part was furrowed 

 five or six inches deep — seed covered the same as the other plat, 

 harrowed with a spike tooth harrow ten days after planting — 

 worked seven times without hilling.
