[137] See Weale’s Papers on “Engineering,” vol. iii. Part V. pp. 1-7, “Steam Navigation.” [138] With regard to the question of the progress of steam-ships in the Royal Navy since then, Mr. T. H. Farrer, of the Board of Trade, remarks, with great force, in a letter I recently received from him: “We hardly know how fast we move. One of my first colleagues at the Board of Trade, in 1850, was Admiral Beechey, an officer of very superior attainments and intelligence, and one who, having been much employed on surveys, was well acquainted with steam-vessels. And yet I well remember his telling me that he did not believe that the Navy of the future—the Royal Navy—ever could consist of steamers! Nor could he endure iron ships. It was a very few years after this that, in company with him, I witnessed one of the most beautiful sights of my life—the Naval Review at Spithead, in the first summer of the Russian war, when the last four or more sailing-vessels of the Royal Navy formed the attacking squadron. I shall never forget the beauty of the scene, when late in the afternoon these magnificent ships came on with a gentle breeze from the east, and the descending sun shed a ‘dying glory’ on their towers of canvas. It was a fit obsequy for the Hearts of Oak of Rodney, Howe, and Nelson.” [139] “Specifications relating to Marine Propulsion,” Part II. p. 127. [140] _Mechanics’ Magazine_, vol. xxxi. p. 225. [141] The first experimental trip of the _Archimedes_ was made on Monday, October 14th, 1839, the second on the following Wednesday, in the presence of Sir Edward Parry, Sir William Symonds, Captains Basil Hall, Austin, and Smith, R.N., and several civil engineers. Subsequently to the Admiralty trials between Dover and Calais, Captain Chappell, R.N., sailed round England and Scotland in her, calling at numerous ports; details of this voyage will be found in Appendix D to Tredgold “On the Steam Engine.” [142] The _Rattler_ was launched from Sheerness Dockyard in April 1843. She was considered a remarkably fine model, and of very unusual length in proportion to her beam, her dimensions being 195 feet extreme length, close upon 33 feet extreme breadth, and 18½ mean depth of hold. Her burden was 888 tons. The log of this vessel from 28th of March to 13th April, 1851, will be found in the Appendix to a Report of a Committee of the House of Commons, 1851, p. 565, where the merits of the screw are examined. [143] The “screw” which Mr. Stevens used in his boat cannot have been of a practical character, or the Americans would not have allowed so valuable an invention to lie dormant for 35 years. [144] Mr. Woodcroft patented, on the 18th of November, 1826, a mode “for propelling boats and vessels,” but no specification was enrolled; and on the 22nd of March, 1832, he “prolonged” his patent “increasing-pitch screw-propeller,” which he then fully described.
