BULLETIN 814, U. S. DEPARTMENT OF AGRICULTURE. 
The average performance of the 2-row planter in drilling corn, 
as reported by 136 farmers, is given in Table XI. Most of these men 
reported that they also used a check rower. As with the check rower 
there seems to be practically no diiference between a day's work in 
drilling in rows 40 and 42 inches apart. However, on the average 
about 2 acres less per day are covered when checking than when 
drilling, this reduction in acreage being due probably to the time 
necessary to move and' set the check-wire stakes, and the attention 
that must be given to the check- rower attachment. 
Both in using a check rower and in drilling corn more men 
reported 20 acres per day than any other amount. However, the 
men using a check rower frequently reported from 15 to 18 acres as

a day's work, and less than 3 per cent gave over 20 acres, while 25 
per cent of the reports on drilling gave more than 20 acres.

CULTIVATING CORN. 
Practically every farmer in the area uses the 1-row, 2-horse riding 
cultivator. (See fig. 3.) About 40 per cent of the men stated that 
they also use 2-row cultivators (fig. 4) , though only two men reported 
the use of the 2-row machine exclusively. (See Table XII.)
