House of Commons, Great Britain, Report from the Select Committee on Steam Carriages… (1831)
“ What advantage in point of expence do you anticipate to the public from the use of steam in propelling Carriages over that by horses?—I have no doubt that when they arrive at tolerably practical state of perfection, passengers will be carried the same distance which they are carried now by horses at the same velocity for one half of the expence, it may be even at less than that in future. ”
