Our Supply of Coal.

Philadelphia Record. Prof, McGee, of the United States Geological Survey, says that a calculation as to the quantity of anthracite coal in the country and the probable consumption leads to the conclusion that such deposits will be exhausted within a century,-while, judging from the known supply, bituminous coal will not last longer than three or four centuries. It is altogether probable, however, that great veins of undiscovered bituminous coal may yet be tapped.
