CANAL OF COMMUNICATION.—The quantity of earth-work to be performed for the canal of communication and irrigation is calculated from the sections at 10,320,884 _met. cub._ from the receipt of water to Lake Timsah. For this work men will easily be found, at the rate of 3 _piast._ (0 _fr._ .75) including all expenses, and each workman will do easily 2 _met._ _per diem_, which reduces the price of the cubic _metre_ to 0 _fr_. 37½. The cost of excavating the canal will therefore be 3,870,331 For the small canal of irrigation, leading from the last channel to Suez, the quantity of earth-work is 2,218,500 _met. cub._ For this it will be necessary to pay the men 0 _fr._ 90 _per diem_, and they will easily do 2 _met._ 25 _cub._, which will be 0 _fr._ 40 per _met. cub._ The cost of this part will therefore be 887,400 Add 10 _per cent._ for tools 6,529,667 Contingencies 173,654 ---------------- Total for the first part _fr._ 72,000,000 ARTICLE II. WORKS OF ART. To give a concise but accurate notion of the expense of the works of art, we shall fix the prime cost of the materials, compared with the prices paid in the execution of the works of the barrage, and then it will be easy to determine the outlay necessary for the present works, as compared with that of the former. ROUGH STONE.—The rough stone used in the barrage comes from the quarries of Toura, situated 30 _kil._ from the place where it is used. It costs 22 _paras_ the _quintal_, or 4 _fr._, 20, the _cubic metre_, delivered on the spot. That which will be used in the works of the Maritime Canal will come from the quarries of Ataka, on the shores of the bay of Suez, at a distance of 20 _kil._ from Suez. This being a calcareous stone, like that of Toura, if it is brought to the boats by a railroad and towed by steamers, there is sure to be a saving in the extraction and transport. We have however, taken the price at 5 _fr._ to cover all difficulties in forming establishments, the higher rate of labour, and the cost of the railroad. This is the price paid for the blocks employed at the port of Cherbourg. At the port of Valencia (in Spain), the extraction of large blocks, the transport to the quay and loading, only cost 4 _fr._ 25. HEWN STONE.—The hewn stone for the barrage, came from the quarries of Toura and Massara, at an average distance of 33 _kil._ from the place where used. These stones were first transported a distance of 6 _kil._ to the banks of the Nile, by means of bullock carts, then transferred to sailing barges, and carried by water to the distance above-mentioned.
