"The traffic of a system of lines, connected with one another, can always be worked more economically and conveniently under one uniform management than by independent Companies. The Company which works the main trunk line, and possesses the principal terminal stations, can run more frequent trains, and make better arrangements for forwarding the traffic of the cross lines, than it could afford to do if two or three separate establishments had to be maintained, and the harmony of arrangements depended upon two or three independent authorities. "It is found also in practice, that unless a very close unity of interest exists among the different portions of what really constitute one great line of communication, it is scarcely possible to introduce that harmony and accuracy of arrangement which are essential to ensure speed and punctuality. Many important branches of traffic also are apt to be neglected, which can only be properly developed where a long consecutive line of Railway is united in one common interest. Coals and heavy goods, for instance, can be conveyed for long distances with a profit, at rates which would be altogether insufficient to remunerate a Company which had only a run of ten or twenty miles: and thus many of the most important benefits of Railways to the community at large can only be obtained by uniting through-lines in one interest."--_Report of Board of Trade on Railways. Sess. 1845._ (20) "The two most expensive commodities in England are crime and poverty; of these the most costly is poverty; and the extent of poverty, by its sufferings, vastly increases the amount of crime. You have heard the expenses of poverty. The cost of crime in England and her penal establishments exceeds a million and a half."--_Speech of Francis Scott, Esq. M.P._ (21) "The circumstance which must first strike any person as extraordinary, in regard to the expatriation of criminals from this country, is the choice of the station to which they have been sent. That a country which, like England, is possessed of an almost boundless tract of unsettled fertile land within four weeks' sail of her own shores, should, in preference, send her criminals to a territory which cannot be reached in less than as many months, thus multiplying the expense of their conveyance, is a course which requires for its justification some better reasons than have ever yet been brought forward."--_A. R. Porter, Esq., Progress of the Nation._ This system has, we believe, come to a close, and Gibraltar and other places fixed upon; (some in Great Britain); but her convicts ought not to be employed at home if it can be avoided, as they of course perform the work that would be performed by the labourers of the country, many of whom are thus thrown out of work.
