"View of the remains of the French Works. These remains are in the southeastern suburbs of the city, about half way between the [African American] Cemetary and the residence of Major William Bowen, seen toward the right of the picture. The banks have an average height, from the bottom of the ditch, of about five feet, and are dotted with pines and chincapins or dwarf chestnuts, the former draped with moss. The ground is an open common, and although it was mid-winter when I was there, it was covered with green grass, bespangled with myriads of little flowers of stellar form. This view is from the direction of the town looking southeast."—Lossing, 1851
