Monument constructed of Georgia marble, consisting of a semi-circular fountain 66 feet broad and 44 feet deep and in the center, a pylon crowned with a globe supported by four eagles connected by garland. A 15 foot statue of Columbus, facing the U. S. Capitol and wrapped in a medieval mantle, stands in front of the pylon in the bow of a ship with its prow extending into the upper basin of the fountain terminating with a winged figurehead representing democracy.
