For the use of a transplanter costing $45 there are charges for 

 replacement and interest averaging $0.28 per acre for depreciation 

 and $0,114 per acre for interest at 6 per cent. 



The repairs on cabbage transplanters average $0,091 per acre *or 

 $0,336 per day used. The average transplanter costs about $45 and 

 the repairs necessary during its life amount to about 36 per cent of 

 the original outlay for the machine. 



ENGINE SPRAYER. 



The average cost of repairs for gasoline-engine-operated spraying 

 outfits is $0.27 per day (Table XIII). The number of trees per acre 

 is so variable that it is most convenient to consider repair charges on 

 the basis of the tree rather than the acre.
