Some coal-tar was burned, or disposed of otherwise than by sale. Some oil-tar was sold, and the income from this is included in the total income from sales of tar, as reported by the Board of Gas Commissioners. (See Note H, Table VI, for income from sales of residuals).

Not all the sales of oil-tar are separately given in the Commissioners' Reports, but from such companies as are so reported it is found that

In 1900, 72% of water-gas made yielded $13,528 from residuals.

From the water-gas yielding the above residuals, there was tar burned, varying from 70,000 to 537,000 gallons per annum.

As nearly as can be determined from the Commissioners' Reports, the total sales of oil-tar did not exceed,—as follows:

Prior to 1895 the sales of oil-tar cannot be determined.

If the net incomes from sales of coal-tar thus determined are considered, and if 12.5 gallons coal-tar are sold per ton of total coal carbonized, then (and only with such qualifications) Column VII, Table V, gives the total gallons coal-tar sold. Column VIII, Table V, gives average price, in cents, received for the coal-tar sold.

NOTE J, TABLE VII.

FOR COAL GAS, INCOME FROM SALES OF RESIDUALS, PER TON

The net sales of coal-tar are obtained by deducting from the total sales of tar, the amounts named in the foot-note to Table V as the limiting income from sales of oil-tar. Prior to 1895, the figures are not corrected for any sales of oil-tar.
