[146] Cf. _Engineering_, 27th March, 1868--'Trevithick was the real inventor of the locomotive;' also Zerah Colburn's 'History of the Locomotive,' p. 13 (ed. 1871); and O. D. Hedley's 'Who invented the Locomotive?' (ed. 1858). The second model had a horizontal instead of a vertical cylinder. His locomotive of 1804, built at Newcastle-on-Tyne, was specially fitted with flanged wheels for running on a railway. [147] Sir Humphry Davy spoke of these machines more euphemistically as Trevithick's 'dragons.' [148] Trevithick was born April 13th, 1771, and died April 22nd, 1833. George Stephenson was born June 9th, 1781, and died Aug. 12th, 1848. [149] Viz., not until 1814--twelve years after Trevithick's locomotive. [150] Brunel, who afterwards constructed the Thames Tunnel, at Wapping, is said to have formed the highest opinion of Trevithick's inventive skill in this operation. (It had been previously attempted by Dodd.) Trevithick very nearly lost his life when the water flooded the driftway, owing to his insisting upon seeing all his men safely out before him. [151] Trevithick's claim to the invention of the screw-propeller was disputed. [152] Earlier attempts were made in 1788 and 1803. The first remunerative steamboat for passengers seems to have been the _Comet_, which ran, in 1812, between Glasgow and Helensburgh, on the Clyde. [153] 'The next step was to call in the aid of Steam to Agriculture. Steam is almost an Englishman.'--_Emerson._ [154] Trevithick, before leaving England for South America in 1816 being pressed for money, sold a half share of his patent in the high-pressure steam expansive pole-engine to Messrs. Williams, of Scorrier, for £200. He remained abroad for ten years. [155] Some of the remains of the machinery were seen lying about on the mountain-sides in 1850. _VIVIAN_, THE SOLDIER. [Illustration: (beginning of chapter vignette.)] _VIVIAN_, THE SOLDIER. 'See! through the battle's lurid haze, How Vivian, as the trumpet blew, Led the last charge at Waterloo.' H. S. STOKES: _Rhymes from Cornwall_. The nest of the Vivian family was Truro; here our hero was born, and here resided his father, John Vivian, who may be called the founder of the copper trade in Cornwall, and who subsequently became Vice-Warden of the Stannaries: but the present seat of the Vivians is Glynn, the ancient residence of the Glynn family, from which place the subject of the following remarks, Richard Hussey, first Baron Vivian of Glynn and Truro, derived the former of his titles. He derived his second name from his grandmother, who was a Miss Hussey, of Okehampton; his grandfather was the Rev. Thomas Vivian, of Comprigney, Kenwyn; he was vicar of Cornwood, Devon, and was a man of some literary ability.
