CANAL OF COMMUNICATION.—For the canal of communication, we have first to erect pumps of 500 horse power in the aggregate, in order to provide amply for all the incidents of navigation, irrigation, losses by filtration and evaporation; as, for irrigation and navigation we only require 800,000 _metres cub. per diem_, while pumps of 500 horse power will supply 1,296,000. STEAM PUMPS.—The steam pumps that have been erected in Egypt, have come to 2,200 _fr._ per horse power, fixed and mounted complete; for this item, therefore, there will be an expenditure of 1,100,000 BARRAGE LOCKS.—There will be six barrage locks with draw-bridges; the locks will be 12 _met._ wide and 54 _met._ long between the gates. The cost of each barrage lock complete will be 300,000 _fr._ and for the six 1,800,000 CULTIVATION OF LANDS.—For bringing the lands into cultivation we must reckon 200 _fr. per feddan_, or 500 _fr. per hectare_. It is true that land may be bought in the country, all prepared with agricultural buildings, magazines, cattle, plant, &c. &c., at the rate of 250 _fr._ the _feddan_ (625 _fr._ the _hectare_), but the agricultural system established on these lands is very defective. The expenditure for 40,000 _feddans_, or 16,000 _hectares_, will be 8,000,000 FIXING THE SANDS.—For fixing the sands we have seen that the cost would be 66 _fr._, 80, the _hectare_. It appears to us advantageous to carry out this operation on a large scale; we have therefore adopted the figure of 24,000 _hectares_ (60,000 _feddans_). The expenditure for this item will be 1,603,200 CONDUIT PIPES.—For the conduit pipes, of which there will be a total length of 80,000 _metres_, we adopt those on the Charmeroi principle, although there are now earthenware pipes very suitable for water courses, and which do not cost half what the Charmeroi pipes do. These latter, 0 _met._, 10, in diameter, which is the size adopted, are laid complete, including the trenches, 1 _met._, 40 deep, at 6 _fr._, 30 _per metre_. On account of the carriage, we put the _metre_ at 8 _fr._, which makes an amount of 640,000 LIGHT HOUSES AND BEACONS.—We assume that there will be two lighthouses, one at the Damietta point, and the other on the Red Sea, at Raz Mohammed. There will be besides, two beacons at the head of the jetties at Pelusium and at Suez. The lighthouses with their lenticular apparatus will cost, the two 150,000 _fr._ and the two beacons 20,000 _fr._ in all 170,000
