New occupations will arise, such as whale and cachalot fishing in the South Seas; pearl fishing in the Persian Gulf and Indian Sea, as well as the pursuit of mother-of-pearl, tortoise-shell and coral. A great part of the Mediterranean fishermen will transport themselves to the Indian Sea, to pursue their occupation, and increase the activity of the navigation in the Maritime Canal.
We may therefore be sure that the cutting through of the Isthmus will increase ten-fold the operations of commerce and navigation; that, as with every undertaking based upon a true principle, the consequences cannot be calculated, and that the idea most exaggerated in appearance, will always be surpassed by the reality.
As, however, we are addressing ourselves to the commercial world, and have to convince all minds, even the most timid, it is necessary that we should fix upon a figure, and that this figure should not startle any one. We have adopted that of 4 milliards (4,000,000,000) of francs, answering to 6,000,000 tons, which, according to what we have been showing, is without doubt, already exceeded at present, or certainly will be, before the close of the undertaking.
We have likewise assumed that of the 6,000,000 tons, 3,000,000 only will take the route of the Canal.
If we had followed the method of estimating adopted in the railway schemes, it would be necessary to make a statement of all the merchandize exchanged between Europe and America on the one part, and Indo-China on the other; then to multiply the figure thus obtained by a coefficient, never less than 3, and which sometimes reaches to 10. The result of this operation would give an enormous product, nevertheless probable. But to remain within the circle of ordinary ideas, instead of tripling the actual figures, we have diminished them by half.
Representing a dividend of about ten per cent., over and above the interest of five per cent., taking the capital at 200,000,000 fr.
We pass over in silence a multitude of sources of revenue, which will not fail to be pretty considerable; such as the supply of water to the population of Suez and Port Timsah, the rent of stations for watering ships, the rent of all the magazines and buildings, which have been employed in the execution of the Canal, the towing of vessels by the steamers purchased by the Company for the service of the dredges and the transport of materials.
