99 INDIAN CORN CULTURE. 
on well-prepared land the drill system will be 
most economical in rapidity of planting and 
cultivating. This means, of course, that a 
modern horse corn-planter shall be used. 
Depth of planting.—On warm, light soil, the 
seed should be planted deeper than where it 
is cold and retentive. The process of vegeta- 
tion is slower on cold than warm land, as the 
temperature is lower at the same depth below 
the surface. In summer if a drouth occurs the 
greater depth of planting on the light soil is 
beneficial to the growing crop. If a low river 
bottom is the corn field, shallow planting will 
do, as crops rarely suffer from lack of moisture 
in such a location. Generally speaking the 
writer believes one anda half incha satisfactory 
depth to plant the seed. 
As bearing on this subject, the follows 
table of results of experiments on depth of 
planting, conducted at the Ohio and Illinois ex- ' 
periment stations, is of interest.* The Ohio 
experiments are average results of six years’ 
work (1885-1888) and those of Illinois of five 
years’ duration (1888-1893):
