Near the USMRR railroad wharf, Alexandria, VA. Jones Point extends across the middle background.
Haupt, United States Military Railway Department. Construction And Transportation. No. 5. Represents the platform on which the bottoms of the arks are constructed. It is elevated 10 feet above the launching ways, supported by stout hinges in the middle, so as to afford facilities for turning over the bottom of the ark when it has been finished ready to receive the sides. The inclined braces which support the projecting part of the platform are removed when the bottom is to be turned, and the manoeuver is effected by ropes passing around the windlasses shown on the back part of the platform.
Near the water is seen an ark on the ways, nearly finished.
