- A Corvette of 1780
This ship shows the new sail plan overcoming the old. The masts carry topsails, topgallantsails, and royals, and what was formerly a lateen sail on the mizzenmast has become a spanker. Furthermore, while the ship carries jibs, she has not yet parted with her spritsails. - Miller’s twin boat on Loch Dalswinton, 1788
An experiment was made by Patrick Miller, a banker in Edinburgh, aided by Mr. Taylor, tutor in his family, and Alexander Symington, a practical engineer. Mr. Miller had a boat built and fitted with a small steam-engine, for his amusement, on Dalswinton Loch, Dumfriesshire. It was a twin-boat, the engine being placed on one side, the boiler on the other, and the paddle-wheel in the centre. It was launched in October, 1788, and attained a speed of five miles an hour. The engine, of one horse-power, is still to be seen in the Andersonian Museum, in Glasgow. Encouraged by his experiment, Mr. Miller bought one of the boats used on the Forth and Clyde Canal, and had a steam-engine constructed for it by the Carron Ironworks Company, under Symington’s superintendence. On December 26th, 1789, this steamboat towed a heavy load on the canal, at a speed of seven miles an hour; but, strange to say, the experiment was dropped as soon as it was tried.
