month. At
Sea each voyage 8 days = 16 monthly = 192 yearly. Coals 25 tons
daily = 4,800 tons yearly, at 40_s._, 9,600_l._ Other charges,
6,820_l._--together 16,400_l._
6. _Trincomalee to Calcutta._
A steamer would proceed from Trincomalee to Calcutta and back, calling
in going and returning at Pondicherry and Madras. The route and time
would be thus:--
Geo. Miles. Days.
Trincomalee to Madras 300 1-1/2
Madras to Calcutta 735 3-1/2
Stop at Calcutta, Coals, &c. 2
Calcutta to Trincomalee, same route 1035 5
---- --
Totals 2070 12
One steam-boat would perform this work, giving two mails each (p. 077)
month; at sea each voyage 12 days[16] = 24 monthly = 288 yearly.
Coals, 25 tons daily = 7200 tons yearly, at 40_s._, 14,400_l._ Other
charges, 6820_l._--together 21,220_l._ per annum.
[Footnote 16: The time here is only ten days; but
the calculation was made for a different division
of the mails, and it has not been thought necessary
to alter it.
The time in which the different distances may be
run has been here stated, but the necessary
arrangements for the arrivals and departures of the
mails will, in some instances, extend that time.
These arrangements resolve the periods into--say
45, 60, 75, 90, 105, 120, &c. &c. days. Thus, if
the mails between Alexandria and Bombay cannot be
back at Alexandria, as they really cannot be,
within 30 days, the object to come up with the
regular return Mediterranean mail for England is
equally attained if it is back at Alexandria within
45 days; and the same principle applies equally to
every other station.]
From Trincomalee eastward to Batavia, Canton, and New South Wales, the
routes, periods, distances, and expenses, would be exactly the same as
those which have already been pointed out in the plan of having the
communications by the Red Sea, under heads Nos. 7, 8, 9, and 10.
