In the year 1829 Stephenson made his famous demonstrations with the _Rocket_, a locomotive running on rails, which attained a speed of thirty miles an hour, contrary to all the predictions of the wiseacres, who had declared the inventor a lunatic for hoping to attain even ten miles. We have already noted that the railway on which the test was made was not built with the expectation of utilizing steam power, that being regarded as a dreamer's vision. Lord Darlington prevented the construction of the road for a time because it chanced to run near his fox covers; and legislative permission was finally secured only with the proviso that the railway was to avoid the region of the preserves. Stephenson with difficulty secured permission to make an experiment on the railway with his engine, in competition with other would-be inventors; and it was his unexpected success that turned the scale in favor of steam power. But even the startling success of the Rocket did not make a great impression upon the British public, the incident being given but slight notice in the periodicals of the day, and no mention being made of it in the _Annual Register_. All this is of interest as showing the attitude of a conservative public toward the steam locomotive running on a railway, and as partially explaining the antagonism to self-propelled road vehicles which found, most unfortunately, an exponent in no less a personage than the Duke of Wellington, then prime minister. The opinion and attitude of the duke were made evident in 1829, in connection with a steam automobile invented by a Mr. Gurney, which was capable of running on an ordinary road at a rate of at least ten miles an hour. The duke was old, and age had strengthened his inherent conservatism. He lent a ready ear to the claims--largely instigated, no doubt, by persons interested in horse traffic--that the automobile on an ordinary road was a menace to public safety, and no doubt his influence had a large share in helping on the unfavorable public opinion and the adverse legislation which were presently to block the further progress of the motor car. Doubtless also the amazing success of the railway locomotive tended to attract the attention of the public away from the automobile, and thus made possible the passage of restrictive laws. In any event, the motor car, notwithstanding its demonstrated possibilities, virtually passed from the scene at about the time when the railway locomotive made its spectacular entrance. That public interest in the matter did not subside immediately, however, is evidenced by the fact that such a book as Gordon's _Treatise on Elementary Locomotion by Means of Steam Carriages on Common Roads_ passed through three editions between the years 1832 and 1836.
