The trouble occasioned by the recent strike of coal miners hascaused man? steam users to investigate the question of the relativecost of oil and coal as a boiler fuel. Some interesting figures fromMr. Charles F. Foster, who was Mechanical Eogiueer of the WorldsColumbian Exposition, are printed in the Engineering Record, andwe reprint the following valuable comparison and formula fromthat journal: In determining equivalent costs of coal and oil for various pricespaid for coal based upon the Worlds Fair results, we can establish. Great Northern Railway Elevator. Buffalo, N. formula in which the price of the oil per gallon iA) multiplied bythe number of gallons burned per horse-power hour iBi plus thecostof handling(C) is equal to the price of the coal per pound ti»multiplied by the number of pounds burned per horse-power hour{E) plus the cost of the handling iF>, or AB + C = DE + F In this case B = .30J7.
