Including oil for station-ary engine.
This table would seem to justify the assumption of 9 mills per milerun , for the consumption of oil and cotton waste by the engine andtender alone.
There is to be found a considerable list of reports in which the aggregate consumption of oil by engines, tenders, and cars, may beseparated from all other items. I have also some manuscript state-ments from which these items can be obtained. The following tableexhibits the aggregate cost of oil for various lines, and the cost re-duced to the mile traveled by the train.

The consumption of oil and tallow may be estimated, in general,at 9 mills per mile run for the engine and tender, and an additionalallowance of i mill for each ton net conveyed one mile.
I have also the consumption of oil and tallow for some other roads,but as these statements manifest great and censurable extravagance,and cannot be used to show the necessary expenditure on a wellconducted work, I have not included them in the preceding list.
Sawing Wood, Pumping Water, and Loading Tenders.- —It isnot easy to collect facts which will exhibit the actual cost of theitems included under the present head for many roads; but it is veryeasy to estimate their average value by direct calculation. We knowthat it is worth, on the average, about 40 cents per cord to saw thewood suitably for this purpose: and we know also that a cord ofwood is sufficient to supply the consumption of the engine while
