plans mentioned is the best fitted for the objects had in view? To determine this, it will be best to consider the communication, each of the three ways in which it may be taken, thus:-- Making Owhyhee the central point of communication, the routes, distances, and periods, and expenses, would be-- Geo. Miles. Days Rialejo to Owhyhee 4,100 22 Owhyhee to Canton 5,200 28 Stop at Canton " 2 Canton to Owhyhee (circuitous) 5,900 39 Owhyhee to Rialejo do. 4,700 29 ------ --- Totals 19,900 120 ------ --- Eight boats would perform this work, giving two mails each month: cost, 76,000_l._; yearly charges, 33,600_l._ _Owhyhee to Sydney._ (p. 061) Geo. Miles. Days. Owhyhee to Sydney, N. S. Wales 4,600 24 Stop at Sydney " 3 Sydney to Otaheite, say 3,900 25 Otaheite to Owhyhee 2,250 13 ------ -- Totals 10,750 65 ------ -- Six packets (one to spare) would perform this work between Owhyhee and Sydney, giving two mails each month: cost, 57,000_l._; yearly charges, 25,200_l._ Admitting that the packets on the Owhyhee and Sydney line take longer time than is here stated, they would still be in time to reach Owhyhee by the time that the Canton mail came up; which in its course with Owhyhee is calculated to be 91 days. In fact, there is thus time sufficient to allow the Owhyhee and Sydney packet time to communicate with Hobart Town, and to call at Otaheite in her outward voyage; as she will do, and, in fact, from the course which she must take, she may and can do, in her return voyage, without any inconvenience or delay whatever. The next plan is, to consider the communications alluded to as to be carried on by making Christmas Island the central point of arrangement; thus:-- _Rialejo to Christmas Isle._ Geo. Miles. Days. Rialejo to Christmas Isle 4000 21 Christmas Isle to Sydney, N. S. Wales 3650 20 Stop at Sydney " 3 Sydney to Christmas Isle, by Otaheite 5100 35 Christmas Isle to Rialejo, by Owhyhee 5800 35 ------ --- Totals 15,500 114 ------ --- Eight packets would perform this work, giving two mails each month: cost, 76,000_l._; yearly charges, 35,600_l._
