In 1830, on the opening of the Liverpool and Manchester Railway, the mails of the district were consigned to the new company for transmission. The railway system developed but slowly, exerting little influence on Post-Office arrangements for the first few years. After public attention had been attracted to railways, many proposals were thrown out for the more quick transmission of mails, to the supercession of the mail-coach. One writer suggested the employment of balloons. Professor Babbage threw out suggestions, in his _Economy of Machinery and Manufactures_, 1832, pp. 218-221, deserving more attention, because in them we see shadowed forth two at least of the greatest enterprises of our time. After proceeding to show, in a manner which must have been interesting to the post-reformers of 1839-40, that if the cost of letter-carrying could be reduced, the result might be (if the Post-Office people chose) a cheaper rate of postage and a corresponding increase in the number of letters, he proceeded to expound a scheme which, though vague, was described in words extremely interesting, seeing that he wrote long anterior to the time of the electric telegraph. Imagine, says he, a series of high pillars erected at frequent intervals, as nearly as possible in a straight line between two post-towns. An iron or steel wire of some thickness must be stretched over proper supports, fixed on these pillars, and terminating at the end, say of four or five miles, in a very strong support, by which the whole may be stretched. He proposed to call each of these places station-houses, where a man should be in attendance. A narrow cylindrical tin case, to contain bags or letters, might be suspended on two wheels rolling upon the wire, whilst an endless wire of smaller size might be made to pass over two drums, one at each end, by which means the cylinder could be moved by the person at the station. Much more of the details follow, and our author thus concludes:--"The difficulties are obvious; but if these were overcome, it would present many advantages besides velocity." _We might have two or three deliveries of letters[74] every day_; we might send expresses at any moment; and "it is not impossible that a stretched wire might itself be made available for a _species of telegraphic communication yet more rapid_." After the first few years of railways, all other speculators quietly withdrew into the shade. In the Post-Office, towards 1838 and 1839, the influence of railways promised soon to be paramount, and it was now that Acts were passed in Parliament "to provide for the conveyance of mails by railways."
