92 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. 

 y 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 and a half inch a satisfactory 

 depth to plant the seed. 



As bearing on this subject, the following 

 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 (1883-1888) and those of Illinois of five 

 years' duration (1888-1893):
