11. What advantage may be derived from the height of the tides, both in the course of the Maritime Canal, in the basin of the Bitter Lakes, and at the Pelusiac mouth?
12. To calculate for the Maritime Canal at a breadth of 100 metres at the level of low water in the Mediterranean, with liberty to reduce it to sixty-five or seventy metres, in those few instances where the necessary excavations and removals would be too considerable. The water line, or depth, is to be calculated at six, at seven, and at eight metres, all below the level of low water in the Mediterranean, in order that the Company may choose, according to the expense, that one of the three depths which shall be most advantageous to its interests, combined with those of the navigation.
13. To obviate the objections relative to the difficulties of navigation in the Red Sea and in the Gulf of Pelusium.
14. To make a rough estimate of the maximum of all the expenses, and to state the probable date when the Canal can be opened for navigation.
15. To accompany the scheme of the Maritime Canal, with a scheme for a Canal of communication, of alimentation, and irrigation derived from the Nile, taking its point of departure between the barrage and Boulak, to reach the Wady, and come as far as Lake Timsah. The dimensions shall be so calculated, that, taking into account its fall and its supply, the Canal may water at least 100,000 feddans at the time of the inundation, and from 20 to 30,000 during the low water of the river. In the vicinity of Lake Timsah, with which it will communicate, this Canal is to be divided into two branches, for simple irrigation; the first to be directed towards Suez, the other towards Pelusium.
16. To examine whether the sands of the downs on the Isthmus, will occasion any obstacle to the construction and maintenance of the Canal, and how they may be turned to account by means of the Irrigating Canal.
17. To furnish a maximum estimate of the secondary Canal derived from the Nile, and to state the length of time required for the works.
18. To give an account of the nature and quality of the materials, which can be easily, and without great cost of transport, applied in the whole of the works, and also the localities from whence they are to be obtained.
19. Finally, to furnish an approximate statement of the minimum anticipated revenues, of the grand Maritime Canal, and of the Canal of alimentation and interior navigation.
I do not mean to confine the labours of MM. Linant Bey and Mougel Bey, within the mere limits indicated in this programme.
