at other times so low that the farmers must draw upon the income 
from other enterprises to pay the freight bills. The enterprise is 
thus highly speculative, and, unless conditions should change radi- 
cally, can never become of great importance in southern Arizona. 
The relative importance on the farms studied of the enterprises 
that have been described is shown further in Table XVII, which 
presents the total receipts on 725 farms arising from each of the 
various enterprises.

of individual animals. 
THE ADAPTATION OF THE FARM ENTERPRISES TO THE SIZE OF THE 
FARM. 1 
In the group of 54 farms of 19 acres or under were 12 dairy farms, 
10 poultry farms, 9 fruit farms, and 5 diversified farms. There 
were 6 farms on which dairying was combined with some other 
enterprise and 4 upon which poultry was combined with some other 
enterprise. The remaining 8 farms in the group were devoted to 
various crop enterprises. Dairy, poultry, and fruit, and their vari- 
ous combinations, give much better results on these farms than other 
enterprises including diversified farming. The average receipts, 
farm income, and labor income of the 41 farms devoted to these 
three enterprises were SI, 185, $760, and $313, respectively, while 
the corresponding figures for the 13 other farms were: Receipts, 
$700; farm income, $516; labor income, $120. 
Among the 45 farms of 20 acres there were 15 dairy farms, 4 
poultry farms, 4 farms that combined poultry with dairying, 2 fruit 
farms, 3 truck farms, 5 hay farms, 2 farms upon which hay and grain 
were combined, 7 diversified farms, and 3 beginners with enter- 
prises not thoroughly established. The dairy and poultry organiza- 
tion produced average results on the 23 farms as follows: Receipts,
