The acreage covered per day increases with the increase in width 

 of the harrow, but not directly in proportion to it. While the larger 

 harrows are most efficient from the standpoint of both man and 

 horse labor, the 20 and 22 foot harrows cover on the average only 

 2 and 1.9 acres per day per foot of width, respectively, while the 

 15 and 16 foot harrows cover 2.2 and 2.4 acres per day per foot of 

 width. 



Out of 422 reports summarized in this table, 217 gave 40 acres as 

 an average day's work. However, very few men using the smaller 

 sizes reported over 40 acres, while 15 per cent of those using the 20 

 and 22 foot sizes said that on an average they covered 50 acres per 

 day. 



PLANTING CORN. 



Except where the fields are small and irregular in shape, nearly 

 all the corn in this region is checked, so that it can be cultivated in 

 both directions. The 2-row planter with check-rower attachment is 

 used universally for this work, about one-half of the farmers making 

 the rows 40 inches apart and the remainder 42 inches:. (See Table 

 X.) Theoretically the amount of ground covered per day w^hen the 

 ixDws are 42 inches apart should be about 5 per cent greater than 

 when the rows are 40 inches apart, but the figiu^es show that on the 

 average there was practically no' difference on these farms.
