THE CosT PER ToN.

Of 121,84 cents, divided among tic n tons, gavo
1853 cents Tor tho total per ton, and tho amount

tho direct expense, The average train appeared
to consist Of nine loaded, nine o,npty cars. and
tho ompty cars, tho total additional oxponHo
would bo worry small: Thus tho exponBp OF harljng
ton tons additional, tile original weight OF train
being $40 tons, amounted to total of 1884
mills for dreot expcnsod. Tho expense for
loading md unloading would amount to Ii
cents per ton, and. taking tho average haul Of
142 mlfeB, tho indirect expenses would bo found
to be. per milo 10 mills, making tho total oxtrn
cost Tor 10 tons, 243A mills, or less than 2l15
