high-wheeled type increase the daily efficiency of the implement 

 from 40 to 90 per cent, making this equipment nearly as efficient as 

 the 2-row planter with two horses. On the 2-row planter it is, of 

 course, necessary to take considerable time in changing the check 

 wire. The 2-row planter with two horses is essentially twice as rapid 

 as the 1-row planter with one horse. With an inexpensive hand 

 planter a man can plant from 60 to 75 per cent as much corn as can be 

 done with a man and one horse using the horse-drawn type of imple- 

 ment. '

Work factors for planting sweet potatoes, cabbage, and tomatoes 

 by hand are arranged by crews in Table XIII. On account of the 

 limited data for each crop, the data for the three crops are averaged 

 in the table. Planting sweet potatoes can be done somewhat more 

 rapidly than planting cabbage, while tomatoes can be set out some- 

 what more rapidly than sweet potatoes. The duty of a man at 

 work of this character is not less than 0.75 acre per day. Compara- 

 tive data for planting these crops with a transplanting machine were 

 not made available because of the limited number reporting trans- 

 planters.

In Table XIV are presented the averages for cutting seed potatoes 

 by hand and with the mechanical cutter, respectively. The cutter 

 does the work somewhat more than 100 per cent faster than it can
