A diminution of two months out of five, must necessarily produce a corresponding advantage in all the expenses which press upon merchandize: thus— 1. The average value of imports and exports between Europe and the extreme East, being about 600 _fr._ per ton, the saving in the interest, on the capital employed at the rate of six _per cent._ will be 6 _fr._ per ton. 2. A ship of 500 tons burthen, costs at the least, fully equipped, 150,000 _fr._, and pays seven _per cent._ _per ann._ to the assurance companies when it navigates the Chinese waters. It only makes at present two voyages in the year including the return; with the Maritime Canal it will be able to make three, which will effect a saving to the owner of two _per cent._ that is 3000 _fr._ or 6 _fr._ per ton. 3. The capital represented by the ship ought to yield an interest arising from the freight, of at least twelve _per cent._ on account of wear and continual reparation. By enabling the ship to make an additional voyage, the Canal gives the means of saving four _per cent._ that is, 6000 _fr._ or 12 _fr._ per ton. 4. This same ship has a crew of fifteen men, exclusive of the captain. Taking the pay of each man at 70 _fr._ per month, and that of the captain at 600 _fr._, it will be found that a saving will be made of 2500 _fr._ which is 5 _fr._ per ton. 5. Although it may be said that the insurance upon merchandize is not determined by the duration of the voyage, but by the risk which the ship runs, according to the route it takes; we do not the less persist in maintaining that the facilities of navigation in the Red Sea being at least equal to those _viâ_ the Cape, the rate of insurance must be lower upon merchandize exposed two months less to the chances of navigation. This rate is usually two and a half _per cent._ upon merchandize going to China; we do not think we are beyond the truth in assuming a diminution of half _per cent._ in favour of the passage by the Canal, which would be a farther saving of 3 _fr._ per ton. By adding up the figures thus obtained, we find a saving of 32 _fr._ per ton on merchandize which shall pass by the Canal: this _minimum_ figure of 32 _fr._ calculated for a diminution of 2,000 leagues; will increase in proportion to the distance gained by the ports nearest to the cutting; for Constantinople, for instance, the saving will be more than double, on account of the 4300 leagues gained by her navigation. Leaving 22 _fr._ of the increased profit to the advantage of navigation, there will remain 10 _fr._ per ton for passage dues in favour of the Company, a figure which is less than two _per cent._ on the estimated average value of the merchandize, at 600 _fr._ per ton. Now, silks, indigos, coffees, sugars, tobaccos, gums, cottons, woollens, wines, spirits, &c. &c. are of greater value than this figure; there is only rice and coal which do not reach it.
