FARM MOTOR TRUCK OPERATION. 27 
There was practically no further reduction in work stock during 
the two and one-half years intervening between the two reports, as 
in 1920 the average number kept per farm was 3.95, and in 1922 it 
was 3.T8. 
FARMS ON WHICH BOTH TRUCKS AND TRACTORS ARE OWNED. 
Three hundred and seven of the 325 truck owners whose reports 
are summarized in this bulletin replied to the inquiry as to whether 
or not the}' owned tractors as well as motor trucks. One hundred 
and thirty-eight, or 45 per cent of these men, stated they did, and 
the remaining 169 said they did not own tractors. In 1920, 322 
men answered a similar question, and of this number 83, or 26 per 
cent, owned tractors, and 74 per cent did not. Of the 138 tractor 
owners 107 gave information regarding the size of their farms and 
the number of horses kept, while 133 of the 169 men who stated 
they did not own tractors gave similar information. There was an 
average of approximately 151 crop-acres per farm in the 107 farms 
where tractors were owned, and 81 crop-acres in those farms where 
tractors were not owned. The crop acres per horse in those farms 
Avhere both tractors and trucks were owned averaged 35, and 24 
where trucks but not tractors were owned. 
Both motor trucks and tractors were owned on 75 per cent of the 
crop farms, 66 per cent of the fruit farms, 48 per cent of the dairy 
farms, 37 per cent of the general farms, and 27 per cent of the truck 
farms.
