Another famous vessel of this period was built in 1814 at Fairlie by William Fyfe. This was the _Industry_, known in later years as the _Coffee Mill_ because of the grinding noise made by the cog-wheels in her machinery.[35] She is also remarkable as being the only trading steamer ever built at the Fairlie yard, for William Fyfe steadfastly refused to construct anything but yachts and smart fishing smacks.[36] [35] Mr. John Hastie’s Address to the Institute of Engineers and Shipbuilders in Scotland, December 2, 1880. [36] “The Clyde Passenger Steamers.” The year 1814 saw the building of the _Princess Charlotte_ and _Prince of Orange_, the first British steamers with engines by Boulton and Watt. In the same year at Dumbarton, Archibald MacLachlan built the _Marjory_, the first steam vessel to enter the Thames. She was sent through the Forth and Clyde Canal and down the east coast, and as her beam was wider than the canal locks her wings had to be removed. Steamship building now proceeded with great energy. In 1815 boats were built in Ireland at Cork, and the first voyage of a steamer from Glasgow to London was made by the _Thames_, while in England the London river steamboat service was opened. The _Thames_, previously the _Argyle_, is described by the _Times_, July 8, 1815, as a steam yacht, and as a “rapid, capacious, and splendid vessel,” which “lately accomplished a voyage of 1500 miles, has twice crossed St. George’s Channel, and came round the Land’s End with a rapidity unknown before in naval history.... She has the peculiar advantage of proceeding either by sails or steam, separated or united, by which means the public have the pleasing certainty of never being detained on the water after dark, much less one or two nights, which has frequently occurred with the old packets.” [Illustration: THE “COMET,” 1812.]
