greater in each group where the owners believe the tractor is profit- 

 able than in the groups where the owners state that the tractor is 

 unprofitable. While this difference is in no case greater than 13 per 

 cent, it is invariably present, which indicates that it has probably 

 had some influence on the opinions of the owners. A further com- 

 parison of gasoline and kerosene tractors will be found in Table IX.

AMOUNT OF MOTIVE POWER PER FARM. 



In Table VI are comparisons of the amount and value of motive 

 power maintained by the two classes of tractor users which are being 

 considered, together with the value of special equipment purchased 

 for use with the tractor and the average size of farms for each group. 



Little difference is shown in the average sizes of tractors, in their 

 cost, or in the value of special equipment for the tractor. But the 

 men who find the tractor profitable, although they show a greater 

 average acreage, do not keep so many horses as those who reported 

 unfavorably. A comparison of results obtained on different sizes of 

 farms is shown in Table XIX.
