This table also shows that for the comparatively few farmers 

 using 14-inch sulky j)lows with three horses in spring plowing about 

 3 acres is an average clay's work. While theoretically the 16-inch 

 plow should cover about 15 per cent more ground in the same length 

 of time, this apparently has not been found true in practice. How- 

 ever, the fact that such a large percentage of the farmers use 16- 

 inch plows shows that they are more satisfactory for this locality. 

 The reports of the small number of farmers who use four horses 

 on their sulky plows show that the fourth horse increases the ef- 

 ficiency of the outfit by a little over 10 per cent. 



FALL PLOWING. 



The performance of 3- and 4-horse teams with 14-inch sulky plows 

 and 3-, 4-, and 5-horse teams with 16-inch plows is given in Table III, 

 The greater frequency of the 4-horse teams and even the use of 

 some 5-horse teams is accounted for by the fact that plowing in 

 the fall is usually about 1 inch deeper than in the spring, and also 

 by the fact that the ground is generally dry and hard to turn.

On an average, outfits of the same size cover about a half acre 

 less per day in the fall than in the spring, due not only to the more 

 difficult conditions mentioned above, but also to the fact that the 

 time spent in the field is about two-thirds of an hour less per day 

 in the fall. As is the case in spring plowing, the 14-inch plow seems 

 to cover practically as much ground per day as the 16-inch size, pro- 

 vided both are drawn by the same number of horses. The addition
