THE ONE-HORSE CULTIVATOR. 
The average 1 -horse cultivator lasts 14 years and does 58 days of 
work (Table X). The farmer who cultivates annually 60 acres, as 
compared with the man who cultivates only 7, obtains over five times 
as much acreage and days of use from a similar implement. 
Although the larger acreages are cultivated by the more expen- 
sive and better implements the machines working the smaller acre- 
ages annually are, nevertheless, the more expensive per acre. The 
average depreciation charge was found to be $0,027 per acre and the 
interest charge, at 6 per cent, is $0,012 per acre.
