CHAPTER XV 
IMPLEMENTS FOR DRY-FARMING 
CueapP land and relatively small acre yields 
characterize dry-farming. Consequently, larger 
areas must be farmed for a given return than in 
humid farming, and the successful pursuit of dry- 
farming compels the adoption of methods that 
enable a man to do the largest amount of effective 
work with the smallest expenditure of energy. The 
careful observations made by Grace, in Utah, lead to 
the belief that, under the conditions prevailing 
in the intermountain country, one man with four 
horses and a sufficient supply of machinery can farm 
160 acres, half of which is summer-fallowed every 
year; and one man may, in favorable seasons under 
a carefully planned system, farm as much as 200 
acres. If one man attempts to handle a larger farm, 
the work is likely to be done in so slipshod a manner 
that the crop yield decreases and the total returns 
are no larger than if 200 acres had been-well tilled. 
One man with four horses would be unable to 
handle even 160 acres were it not for the posses- 
sion of modern machinery; and dry-farming, more 
than any other system of agriculture, is dependent
