FAKM PRACTICE IN THE CULTIVATION OF CORN.

TILLAGE BIPLEMENTS 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.

Fig. 13. — A plank drag, an implement used in some regions instead of a roller to prepare 



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. 

 I nit is well adapted for thor- 

 oughly pulverizing the seed bed 

 "ii such soils. The spring-tooth 

 harrow is also often used on 

 loamy soils (fig. L2). The plank 

 drag (fig. 13) and roller (fig. 1 I) are used on soils which easily be- 

 come cloddy and to compact light, porous soils. For the more pro-
