This evidence is corroborated by all the other witnesses; and great as the noise, and fearful as the horrid gasping of the engine may be, we are not prepared to say that terror may not as naturally be excited in the heart of the most gallant of Houyeneans by the thunder and glitter of a fast coach, rushing downhill at the rate of sixteen miles an hour. In fact, the horse that has ceased--like a young lady after her second season--to be shy, will care no more for a steam-engine than a tilted waggon. And it is decidedly our private and confidential opinion, from a long experience of vivacious roadsters, that a quadruped which maintains its equanimity on encountering a baker's cart with an awning, will face the noisiest and most vociferous of boilers. But granting that the committee is right in coming to this conclusion as far as regards the danger arising to horses, the other objection we alluded to was a poser, from which we shall be glad to see how they extricate themselves--we mean the injury done to the turnpike road. Why, it turns out that a steam-coach does no injury at all; but, from the necessity it is under to sport the widest and strongest of wheels, it acts as a sort of roller, and might pass for a deputy Macadam. Mr Macneil, who has had great experience in road surveying, says that, even in 1831, he had stated that, from the examination he had made as to the wear of iron in the shoes of horses, compared with the wear on the tire of the wheels of carriages, the injury done to the turnpike roads would be much less by steam-carriages than that done by mail and stage coaches drawn by horses. Since then, "I have had practical experience on this point, and have carefully examined the roads in different parts of the country where steam-carriages have been running, and I have every reason to believe the opinion I then gave was correct; indeed, I have not the least doubt in my mind, that if steam-carriages ran generally on the turnpike roads of the kingdom, _one-half of the annual expense of the repairs of these roads would be saved_."
