FUEL AND SUPPLIES 
The outlay for fuel and supplies is determined principally by the 
cost of fuel, which is calculated in terms of oil at 5 cents per 
gallon (Table 13). As the price of fuel changes, the cost of fuel and 
supplies may, without any appreciable error, be obtained by makin 
a change proportional to change in cost of fuel. Table 16 will serve 
as a guide in determining whether oil, coal, or wood is the most 
economical fuel. This tabulation has been prepared on the assump- 
tion that red or black oak, weighing 3,250 pounds per cord, is the 
wood used, that the oil has a density corresponding to 12° Baumé 
and a calorific value of 18,500 British thermal units per pound, and 
that coal has a calorific value of 12,000 British thermal units per 
pound. Oil can be burned more efficiently than coal, and coal can 
be burned more efficiently than wood. It is therefore calculated in 
this table that one cord of wood is equivalent to 1,300 pounds of 
coal, and one pound of oil to 1.6 pounds of coal. It is also calculated 
that it will cost 75 cents per cord to handle the wood, 75 cents per 
ton to handle the coal, and nothing to handle the oil.
