“Sir,—Observing that it is stated in your last number (No. 1232, dated the 20th instant, page 269), under the head of ‘Twenty-one Years’ Retrospect of the Railway System,’ that the greatest speed of Trevithick’s engine was five miles an hour, I think it due to the memory of that extraordinary man to declare that about the year 1808 he laid down a circular railway in a field adjoining the New Road, near or at the spot now forming the southern half of Euston Square; that he placed a locomotive engine, weighing about ten tons, on that railway—on which I rode, with my watch in hand—at the rate of twelve miles an hour; that Mr. Trevithick then gave his opinion that it would go twenty miles an hour, or more, on a straight railway; that the engine was exhibited at one shilling admittance, including a ride for the few who were not too timid; that it ran for some weeks, when a rail broke and occasioned the engine to fly off in a tangent and overturn, the ground being very soft at the time. Mr. Trevithick having expended all his means in erecting the works and enclosure, and the shillings not having come in fast enough to pay current expenses, the engine was not again set on the rail.” SHREWD OBSERVERS. Sir Richard Phillips was a man of foresight, for, in the year 1813, he wrote the following words in his “Morning Walk to Kew,” a book of some popularity in its day:—“I found delight in witnessing at Wandsworth the economy of horse labour on the iron railway. Yet a heavy sigh escaped me as I thought of the inconceivable millions of money which had been spent about Malta, four or five of which might have been the means of extending double lines of iron railway from London to Edinburgh, Glasgow, Holyhead, Milford, Falmouth, Yarmouth, Dover, and Portsmouth. A reward of a single thousand would have supplied coaches and other vehicles of various degrees of speed, with the best tackle for readily turning out; and we might ere this have witnessed our mail coaches running at the rate of ten miles an hour, drawn by a single horse, or impelled fifteen miles an hour by Blenkinsop’s steam engine. Such would have been a legitimate motive for overstepping the income of a nation; and the completion of so great and useful a work would have afforded rational ground for public triumph in general jubilee.” Mr. Edgeworth, writing to James Watt on the 7th of August, 1813, remarks, “I have always thought that steam would become the universal lord, and that we should in time scorn post-horses. An iron railroad would be a cheaper thing than a road on the common construction.” CUVIER’S DESCRIPTION OF THE LOCOMOTIVE.
