The arrangements, and the extent of the internal Post-office establishments of Great Britain, are upon the most splendid and efficient footing. There is nothing of a similar kind in any other country, either in management, or combination, or regularity, that can equal or even be compared to them. It is, however, much otherwise with all her transmarine mail communications. They are all particularly deficient in combination, limited in their operations, and inefficient as regards the machinery employed to carry the mails. This, in a more particular manner, is the case with the West Indies: the small sailing vessels there employed are generally very unfit for such a service, and the steamers sent out to work them, with the exception of the _Flamer_, being only of 100-horse power, and besides badly constructed, are (p. 008) wholly unfit for the service in any way; and even the vessel named, which is 140-horse power, though much superior to any of the other three, the _Carron_, the _Echo_, and the _Albyn_, is still too small to perform her work in proper and reasonable time, or to stem the currents and trade winds, to say nothing of tempests, which, as regards the two former, constantly prevail in the seas in that quarter of the world. It may also be remarked, that to extend or to add to the number of post communications, does not add proportionally to the machinery necessary for the conveyance of these: in other words, if the communications are doubled in number, the machinery used for conveyance is not necessarily doubled, nor the expense consequently doubled. Take, for example, the station between Barbadoes and Jamaica: with two mails each month, this could not be effected with fewer than three steam-boats; but the same number of steamers will, without inconvenience, extend the communication to Havannah, and take in, at the same time, several important places extra. A judicious and proper combination and regularity in all movements can, with the same machinery, and with but little additional expense, perform, in some instances double, and in many instances nearly double work.
