20 November and 25 December 1884, 15 January and 2 April 1885, 14 January and 4 February 1886, 29 October and 24 November 1887, 18 April 1889 and 10 February 1898; Marine Review 1 December 1887 and 30 December 1897; Toronto Globe 5 November 1920. THOMSON see DAVID G. THOMSON TOILER motor canaller (C 129767) (signal letters HSLG). Original as motor vessel: 1,659 tons gross, 1,334 net, 248' (between perpendiculars) 255.4' (overall). Capacity 2,230 tons or 86,000 bushels. Rebuilt as steamer: 1,692 tons gross, 1,026 net. Rebuilt as salvage barge: 1,686 tons gross. Launched by Swan, Hunter and Wigham Richardson at Newcastle-on-Tyne England 1910. Yard #840. As built she had no "boiler house", no funnel and no booms on her masts. Twin two-cycle reversible four-cylinder Polar diesels of 180 brake horse power (200 indicated horsepower) at 280 rpm. TOILER's diesel machinery weighed half as much (60 tons) as steam engines and boilers would have been. The diesels also took up less space than a steam plant would have needed. Oil fuel consumption was estimated to be a quarter of what would be achieved with coal. As a result, TOILER had a capacity 15,000 bushels larger than a steam vessel of the same dimensions. TOILER also required a smaller crew than steamships did because she did not need firemen to run a boiler. This freighter was the first of four diesel or diesel-electric canallers built in the UK close together in time, three of which were by Swan Hunter. When she was built TOILER was the largest motor vessel in the world. She was the first large motor vessel to be built in the UK, the first motor vessel to cross the Atlantic and the first motor vessel on the lakes with the exception of the American ferry MISS VANDENBURG (U 206195, 197 gross tons) that ran across the St. Lawrence between Prescott Ontario and Ogdensburg New York. TOILER was also the first canaller to have twin screws. In appearance, TOILER was a near sister to CALGARY (C 133514, 1,639 tons), managed by Playfair, which was also built and initially owned by Swan Hunter, but CALGARY had a funnel, "engine house" and booms. More importantly, CALGARY also had more power, with twin 260 brake horse power engines as opposed to the twin 180 brake horse power engines fitted in TOILER. The engines of both vessels were built by Aktiebolaget Diesels Motorer of Stockholm Sweden. The other two of the first four motor canallers were the package freighter FORDONIAN (C 133077, 2,368 tons) of 1912 and Montreal Transportation Co.'s TYNEMOUNT (see below). FORDONIAN was first fitted with a Belgian Carels design single open four-cylinder two-stroke diesel of 750 brake horse power. She was soon converted to steam. In 1922 an 8 cyl. two-stroke Ansaldo diesel- electric plant was installed and finally in 1934 she received a 6 80
