Three boats would perform this work, giving two mails each month. Each
boat would be at sea 36 days each voyage = 72 monthly = 864 yearly: 25
tons coals daily, 21,600 tons yearly--43,200_l._ At Trincomalee, a
spare boat would require to be stationed, in case of accidents, which
would make four for the station; prime cost, 96,000_l._, and one
sailing-vessel, 2,000_l._ The yearly charges for provisions, wages,
&c. &c. will be 6820_l._ each, and 1000_l._ for the sailing-vessel is
28,280_l._, which, together with the expense of coals, amount to
71,480_l._

Three boats would perform this work, giving two mails each month; (p. 071)
but in case of accidents, there would require to be one spare boat on
the station, to be stationed either at Batavia or Sydney. The cost of
the four would be 96,000_l._ Each boat actively employed would be at
sea 42 days each voyage = 84 monthly = 1008 yearly: 25 tons coals daily
is 25,200 tons yearly, at 40_s._, 50,400_l._ The yearly expenditure of
each boat besides would be 6820_l._; for four, 27,280_l._, together
with coals, 77,680_l._

It is unnecessary to dwell on the immense advantages which such a plan
of mail communications as this would give to the commercial world in
general, and to the commercial interests of the United Kingdom
