Alabama Marble Company,
Gantt's Quarry
Plate XII. Alabama Marble Co. - Gantt's Quarry, p. 147. "View looking nearly west into quarry of Alabama Marble Co. at Gantt's Quarry, showing in the background the former method of quarrying by making the cuts respectively down the slope and at right angles to it. In the foreground can be seen the present method of quarrying diagonal to the strike and dip direction and parallel with the major jointing directions. This method assures a higher percentage of sound marble, since by its use the unsoundness in the quarry block is less likely to pass diagonally through the block."
