FAEM PRACTICE IN THE CULTIVATION OF CORN.

TILLAGE IMPLEMENTS USED AFTER PLOWING AND BEFORE 
PLANTING. 
Table VII is presented to show what implements are used in pre- 
paring the land for corn after plowing and to show where and to 
what extent each implement is used. The kind of implement used is 
governed by the type of farming practiced, the topography of the 
land, and the type of soil.

cloddy land for corn. 
The spike-tooth harrow (fig. 8) is extensively used in almost every 
region visited. 
The disk harrow (fig. 9) is also extensively used, but where the 
land is extremely rolling or 
stony the spring-tooth harrow" 
(fig. 10) is more popular. The 
acme harrow (fig. 11) is used 
only on soils free from stones, 
but is well adapted for thor- 
oughly pulverizing the seed bed 
on such soils. The spring-tooth 
harrow is also often used on 
loamy soils (fig. 12). The plank 
drag (fig. 13) and roller (fig. 14) are used on soils which easily be- 
come cloddy and to compact light, porous soils. For the more pro-
