"The same firm [the Reed brothers] is opening a mine on the Benedict property, about one-fourth of a mile below the borough of Dudley. The Barnet vein, which here has a thickness of four feet, has been reached through a tunnel of four hundred yards, and preparations for shipping coal are in progress. The daily capacity of this mine will be three hundred tons. This work is under W. Scott Reed's superintendence."1
