Launched in Montreal in 1854 as the Kingston, she was one of the finest Canadian steamboats of her day on the
Upper St. Lawrence and Lake Ontario. Indeed, when the Prince of Wales (later Edward VII) toured Canada in 1860,
she was chosen to be his 'floating palace.' Stained glass windows, pianos, and luxurious carpeting comprised part of
her decor. In 1872 she was gutted by fire while off Grenadier Island in the St. Lawrence River. Rebuilt as the
Bavarian, she burned a second time in the fall of 1873. The iron hull, rebuilt yet again, at Power's shipyard at
Kingston, was this time christened the Algerian. Under this name she served in the Royal Mail Line for the Richelieu
and Ontario Navigation Company until the turn of the century, running between Toronto and Montreal. Renamed the
Cornwall in 1905 she gradually assumed a stand-by role, filling in when one of her newer, faster line mates had a
breakdown.

Near the end of 1911 she was purchased by the Calvin Company of Garden Island, opposite Kingston. In their hands
she underwent a remarkable transformation. The Calvin's weren't interested in passengers, their business since the
1830's had been the movement of lumber and ship building, with a towing and wrecking business on the side. They
removed much of the upper works and added salvage equipment and a derrick for 'lightening' the cargo of stranded
vessels. After two highly remunerative seasons the Cornwall was sold to the Donnelly Salvage and Wrecking
Company, who used her for many more years as a wrecker. As late as 1928 they still considered her the flagship of
their fleet. With her 40 ton derrick, clamshell outfit, 12 inch rotary steam pumps, diving equipment, air compressor
lifting jacks, wrecking hawsers, syphons, steam connections and steel hose, she was well equipped to fulfill her role of
rescuing vessels in trouble.

In the winter of 1928, the Donnelly Salvage & Wrecking Co. was one of several Great Lakes salvage outfits
purchased and combined to form Sin Mac Lines, later Sincennes-McNaughton Tugs Ltd.

Shortly thereafter her owners decided that the Cornwall had finally outlived her usefulness. Her iron hull was tired
after 75 years of continuous use. The late Vic Ruttle of Portsmouth, an old Donnelly hand, described her last voyage.
About 1930, just before Christmas, they towed her out in a snow storm. Her engine had been removed but her boilers,
paddle-wheels and cabins were intact. Not being anxious to hang around, the crew hurried her on her way by the
generous use of dynamite. He wasn't sure of her exact location but thought she was somewhere near Amherst Island.

When found she was pretty much as Mr. Ruttle described her. Sitting upright on the bottom in 70 feet of water, the
176 foot long iron hull is split open in several places, either from the dynamite or impact with the bottom. The engine
is missing from between the large a-frame, but the boilers are still in place, sticking some 20 feet off the bottom. The
ten bladed feathering paddle wheels, 20 feet in diameter, are intact. The cabins are all gone but a great deal of
wood-work lies on the bottom around the outside of the hull. Scattered throughout the wreckage are other items of
interest; wooden barrels, tools, steam pipes, a bed, a ladder. At the bow a large piece of fore deck still has the
windlass in place; a small engine and port-holes may also be seen here.

The sandy bottom and relatively shallow depth ensure that there is plenty of light; visibility during the summer is
often in the 15-20 foot range. The lack of silt inside the hull allows divers to examine the construction methods used
on what is only the fourth commercial iron vessel on the Great Lakes
