Lake Timsah, situated nearly midway between the two Seas, at the entrance of the _Wady Tomilat_, will form, as we have said, an inland port, to which both the outward and inward navigation will tend. On its shores will be established magazines, stables, workshops for repairs, as well as 1500 _metres_ of quay walls for mooring vessels and embarking merchandize. For, as the illustrious author of the work on the canal of Nicaragua well expresses it, the proposed Canal must not be a mere cutting destined solely to form a passage from one sea to the other for the produce of Europe, but it must make Egypt a prosperous state by enabling her to dispose of her interior produce, and a powerful one by the extent of her commerce. As for the two entrances, whether from the Red Sea or the Mediterranean, all that is necessary is, that ships shall be able to approach at all seasons, and find certain and effectual shelter in bad weather. Now the roadstead of Suez is sheltered from every wind except the south-east. It will therefore be sufficient to prolong the eastern jetty to a certain distance beyond the western to render the shelter complete. All the vessels which now take their stations in the roadstead ride out the bad weather very well, and the magazine corvette belonging to the English Company which has been anchored there for the last two years and a half has suffered no damage. Thus, at the Suez extremity, it will be sufficient to establish two jetties, forming the entrance channel from the Red Sea, and to prolong them sufficiently far into the roadstead to reach the required depth of water, in order that vessels entering may have a draught of 7 _m._, 50 to 8 _met._ at low water. The eastern jetty must be 150 _met._ longer than the western for the reasons we have just given. At Pelusium, the two jetties, in order to reach the depth of 7 _m._, 50 to 8 _met._ must be at least 6000 _met._ in length; but if it should be feared that the channel thus formed would not be sufficiently safe for the approach of vessels, and in order to meet objections, the real value of which have yet to be tested, we have projected a sheltered roadstead in front of these jetties by means of a grand mole from 450 to 500 _met._ in length, placed in such a manner as to afford shelter to vessels in bad weather, and to enable them to enter the channel at their convenience.
