That facility of intercourse creates commerce, and commerce carries with it civilization, is an axiom founded on universal experience. Where seeming exceptions to it are found, they may be traced to the blind selfishness of human legislation, counteracting the natural laws established by the all-wise and beneficent Governor of the universe. A project, therefore, which, by severing two continents, proposes to change the whole course of commerce and communication between the eastern and western worlds, and approximate by many thousand miles the knowledge and industry of the west to the ignorance and barbarism of the east, presents considerations of a nature to excite the imagination, and to awaken some of our best feelings in its favour. In dealing with it, the writer, however, purposes to limit himself to a strictly practical view of the subject. He will state his facts with accuracy,—place every circumstance, whether for or against the undertaking, as far as his information enables him to judge, impartially before the reader,—and thus leave him to form his own opinion as to the practicability of accomplishing the contemplated enterprise, and of its utility should it be accomplished. The writer deems it proper to add, that the matter was some time since submitted by him to the consideration of Her Majesty’s Government, and that the extract from M. Linant’s Survey of the Isthmus, herein given, appears in the “_Commercial Tariffs, Regulations, &c., of Foreign Countries, part 10, presented to both Houses of Parliament, by command of Her Majesty, 14th July, 1843_,” being part of those valuable compilations, for which it is well known the country is indebted to the talents and industry of Mr. Macgregor, of the Board of Trade. PHYSICAL PRACTICABILITY OF THE ENTERPRISE. The improvement of our communication with the East has been, for some time past, an object of much public solicitude, and in proportion to the progress made in its developement, its importance becomes more and more manifest. The establishment of a steam communication with India, &c., _viâ_ the Mediterranean and the Red Sea, although as yet only in its infancy, has already been productive of considerable benefit, both to Great Britain and her Oriental dependencies. But, although the steam communication presents a greatly improved means of transit by this route for passengers and letters, it cannot, except in a comparatively very limited degree, be made available for the general purposes of commerce. The transport of all articles of merchandize of moderate value, compared to their bulk or weight, must, from the small stowage-room afforded by steam vessels, and the expense of the transit across Egypt, continue to be effected by means of sailing vessels navigating by the long and circuitous route round the Cape of Good Hope.
