View of the ordnance test shed near the the Navy Yard's waterfront, taken by Brady & Company in June 1866. Note the cannon near the shed, some on field carriages and others on naval carriages, and the steamer tied up to the waterfront beyond the shed. The photograph, which has been badly water-damaged, looks southwest from a location in the present (1997) Willard Park, south of the present Building 111.
