[Footnote 17: The same remark regarding the cost of
steamers, will apply here, that has been made in
the Plan proposed for the Western World.]

The first deduction is the sum for the saving in quantity and price of
coals, as aftermentioned; the last sum shows the difference of cost
and expenditure of the route by the Red Sea, as compared with the
route by the Cape of Good Hope; bearing in mind, however, that the
expense of the establishment from Falmouth to Alexandria would still
remain, admitting that the route by the Cape of Good Hope was adopted.

In the preceding calculation of expenses, the amount is taken
calculating that the work is to be done wholly by steam, and at the
average rate of 200 geographical miles per day. The use of sails,
however, will propel a vessel at the average rate of 2-1/2 miles per
hour throughout a general voyage; consequently, _one-fourth_ should
be deducted from the quantity of coals used. This will amount to (p. 079)
31,935 tons, value 44,587_l._, less 10 per cent. allowed for wastage
on the whole, is 12,770 tons, 17,795_l._, which leaves the net saving
of 26,792_l._ Next, the value of coals supplied to the eastward of the
Cape of Good Hope is calculated at 40_s._ per ton, as received from
Europe. But coals may be supplied in all places to the eastward of the
Cape of Good Hope at 30_s._ per ton, thus:--They can be purchased
excellent, and in abundance, at 9_s._ per ton at Sydney, New South
Wales. Ships coming from that place to ports in the East Indies, and
the Mauritius, for freight, would carry these coals, and be glad to
convey and to sell them at 30_s._ per ton, a profit of 21_s._, instead
of making nothing, as at present. A further deduction, therefore, of
10_s._ per ton, or one-fourth in value, on the quantity used to the
eastward of the Cape, is to be made, which will amount to 44,650_l._,
and which, together with the above balance of 26,792_l._, makes the
sum of 71,442_l._ to be deducted from the total amount of expenditure.

Next, as to the rate of speed--it is calculated throughout the voyage,
at the rate of 200 geographical miles per day. In running before the
wind, and with the monsoons, the vessels would make more, and in
