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.

The principal object, therefore, of the contemplated Canal, would be to open a shorter route between Europe and the East, which could be availed of by sailing as well as by steam vessels, and thus serve the general purposes of commercial intercourse.

Previously to proceeding to treat of the practicability of opening such a canal, it may be proper to explain how it has fallen to my lot to deal with this subject:—

In the year 1841, I visited Egypt. While there, my attention was, among other matters, directed to the question which has so frequently been mooted, although never hitherto, I think, satisfactorily treated, viz. the practicability of re-opening the ancient Canal through the Isthmus of Suez, said to have once joined the Red Sea and the Mediterranean.

In following up this object, I became acquainted with M. Adolphe Linant, of Cairo, a French Civil Engineer, of considerable reputation, and who has been in the employ of the Pacha of Egypt, for, I believe, upwards of twenty years.

I found that M. Linant had devoted a great deal of time and labour to the practical investigation of this subject, had recently completed an elaborate survey of the Isthmus, and was in possession of much detailed information derived from a personal examination of the localities through which the proposed Canal would have to be cut. Under certain conditions I induced him to furnish me with a memoir on the subject, accompanied by a manuscript map of his Survey of the Isthmus of Suez, and of Lower Egypt, in which the site of the ancient and track of the proposed Canal are laid down with great minuteness. In short, the map, now in my possession, which is on a large scale, contains a far more complete view of Lower Egypt than any hitherto executed.
