Ruins of Fort Ste. Marie II

C.W. Jefferys' notes about this picture from The Picture Gallery of Canadian History Volume 1

The cannon is a curious piece of artillery, unlike that of the period, and possibly is a discarded specimen of an earlier date. The fore part of the barrel consists of thick wide rings of iron welded together; the rear portion is of bronze, octagonal in shape, and with a projection from the butt, which suggests its use as a handle to direct the cannon when mounted on a swivel, as shown in the illustration on page 176.
