The reported and adjusted data for seeding with a broadcast seeder, 
a knapsack sower, and a wheelbarrow sower are brought together in 
Table XL With the wheelbarrow seed sower the 14-foot width w r as 
used by 40 per cent of farmers, the 16-foot width by 23 per cent, and 
the 12-foot sower by 18 per cent. While the acreage planted daily 
increased with the increasing width, it was seen that the proportion 
of increase fell off at the same time, indicating that the 16-foot width 
approaches the mechanical limit to convenience in manipulation.

In Table XII there are grouped the original averages for planting 
corn and cotton in rows 42 inches apart, the most common width. 
Adjusted acreages are also included and a scale of allowances for each 
6 inches difference in width of row. As with other tables in this 
bulletin, Table XII is based on analytical tables covering the entire 
number reporting for these operations. It was found that 41 per cent 
of farmers plant corn and cotton in rows 42 inches wide, while about 
equal percentages plant in rows 36, 44, and 48 inches apart, respec- 
tively. Throughout the country the range is from 10 to 72 inches. In 
these operations two horses are used by 61 per cent, and 39 per cent 
use one horse. The 2-row planter is used by 54 per cent and the 
1-row planter by 46 per cent. Comparatively few growers use two 
horses with a 1-row planter, but the meager data for this group 
indicated that the addition of one horse and the advantage of the
