The highest royalties charged, such as those in Wyoming and Utah, are due to the local conditions. In the Appalachian region there is no marked difference except in the case of anthracite and the high grade coking coals. These prices are high for the reason that the quantities of these coals are limited and command a correspondingly higher market price. Royalties in the east are on the increase. The same condition will undoubtedly prevail in the State of Washington especially in the better grades of coal, which are rapidly becoming exhausted. A coal bed one foot thick with a specific gravity of 1.35 (which is the average specific gravity for bituminous coal) will contain approximately 1,750 tons per acre. Fifteen hundred tons per acre-foot production is considered very good mining, and as a rule about thirteen hundred tons per acre-foot is the average. However, in order that the operator be given the benefit of the doubt, it may be assumed that only one thousand tons per acre-foot be recoverable; then with a coal bed such as the McKay of Franklin and Black Diamond, which averages about five feet for the lower bench, we would get five thousand tons per acre for this bed alone. If the value of the coal in the ground be based on the royalty rate, we would have, at ten cents per ton, a value of $500 per acre for the one bed alone; and obviously if the royalty were twenty cents per ton we would have a valuation of $1,000 per acre. As an example of the value of coal land, based on a royalty basis, Ashley quotes an instance where the Pittsburg bed in the Connellsville region, which more
