FARM PEACTICE IN THE CULTIVATION OF CORN. 3 
and before planting, and also gives in detail the tillage operations 
after planting. In addition to these tables a description is given 
of each section studied, discussing the general conditions and cus- 
toms found there. 
It is not improbable that tillage methods found in some sections 
of the country could, to a greater or less extent, be profitably em- 
ployed in other sections. In this publication, however, we are con- 
cerned merely with setting forth the findings on actual tillage 
methods employed by representative corn growers in the areas 
studied, and no attempt has been made to make recommendations 
based on the results of these studies.

GENERAL STATEMENT. 
The subject of tillage of corn can properly be divided into two 
parts. The first has to do with the preparation of the seed bed, 
and the second with the cultivation of the growing crop. Both in 
the preparation of the seed bed and in intertillage the prevailing con-
