_The West Indian Station._

This station is one of the most important, and extensive, and

complicated of the whole, and one where steam-vessels can be employed

with the most beneficial effects. The prevailing winds and currents,

however, render it necessary that the vessels employed should be of

high power, in order to enable them to stem those winds and currents.

Into the Gulf of Mexico, through the Windward islands, sets; first,

the equatorial current; secondly, the prodigious current occasioned by

the influx of the waters of the great river Maranon, and of the

several rivers which flow through British, Dutch, and French Guiana;

thirdly, the current occasioned by the influx of the waters of the

great river Oronoque, through the Gulf of Paria, between the island of

Trinidad and the mainland of South America. These united waters,

directed by the trade winds, blowing always from the eastward,

occasion a current of such force, running westward from the Windward

Islands to the shores of Mexico, that it is frequently impossible for

the best sailing vessels to make their way through it. Steam-boats,

therefore, of at least 240-horse power, are indispensably necessary,

in order that they may not only be able to stem these winds and

currents, and carry a sufficient quantity of coals, but also to afford

spacious and well-ventilated accommodation, both for the crews

attached to them, and also the passengers which may travel by them.

Without such, neither the one nor the other could ever enjoy health,

nor could the despatches of Government, and the correspondence of

individuals, be conveyed with that celerity and regularity which these

could otherwise be, and which it is necessary that they should be.

In carrying a more general plan into effect, no reasonable or

necessary expense ought to be spared by the country. In such a general

plan it will be seen by the subsequent details, that the (p. 029)

steam-boats of the power mentioned, assisted by nine sailing schooners

(at present ten, are employed in less than half the work,) would be

sufficient to convey the mails from Barbadoes to every place of

importance in the western Tropical Archipelago, or connected with it.

This force would give two mails each month to every island and colony

from Demerara to Vera Cruz; taking in Laguayra, Carthagena, Chagres,

Honduras, the principal parts of Cuba and Porto Rico. From Demerara to

Havannah and Chagres, &c. inclusive, every colony and place would be

able to reply to the letters received from Europe, or the Colonies, by

the same packet which brought them; and still that packet remain in

the West Indies a shorter period than the packets now do.

In this department there are two stations, however, of such vital

importance, that the considerable additional expense which will be

required to place steam-boats on them from the outset, ought not to be

taken into consideration. These are, first, the station between

Jamaica and Chagres; and, secondly, the station between Jamaica, Cuba,

and Vera Cruz. The first goes to connect the Great Pacific Ocean, and

the coasts thereof, with Europe and the eastern coasts of America, and

on which former coasts a steam mail communication has been already

concerted. Through the channel from Panama to Chagres will be

concentrated, as it were, into a funnel the whole movements,

travelling and mail communications and money transactions of the

western coasts of America, from California on the north, to Valparaiso

on the south, the whole of which again must converge to and diverge

from Jamaica.[2] The second station, or that from Cuba to Vera (p. 030)

Cruz, is little inferior in importance to the other, that town and

Tampico being the great outlets of the trade and the commerce, but

more especially the outlets of specie from the kingdom or empire of

Mexico. A steamer on this station becomes indispensable, in order to

secure the safe conveyance of specie, because small sailing vessels

would be liable to be attacked and plundered by pirates. With steamers

all would be safe.

[Footnote 2: Should the Colombian Government

obstinately and ignorantly oppose the transmission

of mails across the isthmus from Chagres to Panama,

or propose to shackle this point of communication

with unreasonable and inadmissible restrictions,

then in that case there remains a point, it is

believed, more practicable, safer, and more

eligible, where the communication could be

effected, namely, in the State of Guatemala, or

Central America, by the River St. Juan's and Lake

Nicaragua, both of which are navigable for vessels

of any size. The south-west shores of the lake in

question approach to within fourteen or fifteen

miles of the Pacific, and this distance, in one

place, through a valley nearly level throughout,

and at but little elevation above the level of the

sea. From Lake Managua, or Leon, the distance to

the sea is still shorter, being, in one place,

according to good maps, not more than eight to ten

miles. From this lake also, and the capital, Leon,

the distance north-west to Rialejo, a fine port on

the Pacific, is twenty-three miles, and through an

accessible, if not very easy country. The

Government of the Republic of Guatemala, or Central

America, would doubtless be ready to afford every

facility to open such a communication, which would

prove the greatest and most certain means of

improving their country. Moreover, if a ready

communication is once afforded, from any point on

the east coast of America, in the places alluded

to, it would speedily become the object and the

interest of the Chilian, the Peruvian, and the

Mexican Governments to watch and to see that the

communication with the world to the eastward should

not only be rendered secure, but be maintained.

Also, with a communication opened in this quarter,

such as it is believed can be opened, the commerce

and communications between North America and

Europe, and New South Wales, China, and all Eastern

Asia, would most certainly, as it could most

advantageously and expeditiously, be carried on by

it.]

Two powerful steamers would be sufficient for both stations, in order

to carry two mails each month. That steamer to run between Cuba and

Vera Cruz, would always be in time with the return mails for the

following packet from Europe; while that boat which runs between

Jamaica and Chagres would, by returning immediately by the route

afterwards pointed out, always be in time for the same packet at

Jamaica. To stop at Chagres for the mails from the Pacific would not

be advisable or proper, because the arrival of these mails at Chagres

could not be calculated upon with any certainty. If at Chagres when

the outward mail arrives, good and well, they would be immediately

taken up and carried forward; but if not, then they would be brought

forward by it on the next voyage, and in time for the following

European packet.

The mails for Honduras will be most conveniently forwarded from

Montego Bay, Jamaica. With the mails for the western parts of that

island they could be landed at Savannah la Mar, and thence carried by

land with the others, about twenty-five miles, to Montego Bay. From

thence a good schooner would proceed with those for Honduras and (p. 031)

Trinidad de Cuba; and having readied Honduras, return to Montego Bay

by Trinidad de Cuba. By this arrangement, Honduras rather gains more

than by the plan first proposed, to go from Batavano; and the letters

from thence will still and always be in excellent time for the

following packet, making every allowance for casualties during the

voyage. The steamer could then proceed direct from Jamaica to

Havannah, which would save one day each voyage, besides avoiding the

difficult navigation about Batavano. The coals saved yearly would be

1100 tons, 1475_l._, which would do more than pay the expenses for an

additional schooner for the Honduras communication; for, by this

arrangement, two schooners, instead of one, will be necessary. Their

route and time would be--Montego Bay to Trinidad de Cuba, 172 miles,

1-1/2 day; Trinidad de Cuba to Honduras, 520 miles, 3-1/2 days; back

to Montego Bay by Trinidad de Cuba, 692 miles, 10 days; stop at

Honduras 3 days; in all 18 days.

Bermuda being a great naval depôt, a ready communication between it

and every part of the West Indies becomes an object of the greatest

importance. Under the general arrangement proposed, this communication

can be best effected from and with Cape Nichola Mole, Hayti; because

the downward steamer from Barbadoes, with the European and other

mails, will have passed St. Thomas before the steamer returning from

Jamaica, &c., comes up; by which means all the letters from Jamaica,

and every other place to the westward, would, were St. Thomas made the

starting point, be obliged to remain at that island till the arrival

of a following packet; whereas, starting from Cape Nichola Mole, the

mails, both from the eastward and the westward, and also those brought

from Europe, would go forward to a day. Moreover, owing to the winds

which prevail in those seas, vessels running between Cape Nichola Mole

and Bermuda would make passages equally quick, if not quicker, than

vessels running between St. Thomas and Bermuda could generally do. The

courses and distances stand thus:--

(p. 032)

Geo. Miles. Days.

St. Thomas to Bermuda. Nearly due N. 840 9

Cape Nichola Mole to do. N. 32° E. 890 10

Nassau to Bermuda N. 57° E. 800 7

Crooked Island to Bermuda 740 7

Ditto to Cape Nichola Mole S. 19° W. 146 1

Ditto to Nassau 270 1-1/2

Cape Nichola Mole to do. N. 56° W. 380 2-1/2

The communication might still, however, be from St. Thomas, the boat

destined for Bermuda stopping at that island, when this was necessary,

one day, until the boat from Jamaica came up; taking particular care

always to be back at St. Thomas, from Bermuda, before the steamers

with the outward mails from Europe came down from Barbadoes, in order

that the letters from Bermuda for Jamaica, and all places to the

westward of St. Thomas, may go forward by the steamer in question.

This department, however, for Bermuda may, it is conceived, be best

amalgamated and interwoven with the Cape Nichola Mole, Nassau, and

Crooked Island (_the Bermuda mail vessels going and returning by

Crooked Island_) department; as the practical working of the whole

scheme may point out to be most advisable.

In the event of packets arriving from England at Barbadoes within a

day or two of each other, as is sometimes the case under the existing

arrangements, then on the Barbadoes and Demerara stations, let a good

sailing vessel, on the arrival of such packet, take the place of the

steamer for the voyage. Unless, in case of calm weather, this sailing

vessel could do the work thus:--Barbadoes to Demerara, four days; stop

there two days, forwarding the mails for Berbice by land; thence with

the return mails proceed on by Tobago and St. Vincents in five days,

to the packet at Grenada, found, in such a case, either waiting one

day longer at Grenada, or else beating up to St. Vincents, there to

meet the Guiana and the Tobago mails, and which the packet has time to

do. This would occasion little irregularity or delay, because the

cause of the detention, should detention occur, would always be known.

Moreover, the season of the year when the outward packets arrive at

Barbadoes the most irregularly, is during the winter months, from (p. 033)

November to March, and in which period the calms--the greatest

obstructions, in many cases, to sailing vessels amongst the Windward

Islands--are almost unknown.

The same temporary substitute could be applied, under similar

circumstances, on the stations between Jamaica and Chagres, and

between Cuba and Vera Cruz. Even if these places were once or twice in

the year to miss a return mail to Europe, it would not be of such

great importance, because each place having then two mails every

month, the detained mail would go forward by the next opportunity,

while it would save to Government, or to a contracting company, a very

serious expense, which would otherwise be incurred if they were

obliged to have additional steamers for this _probable_ part of the

service.

Further, in the event of any accident happening to any steam-boat on

the great line from Barbadoes to Jamaica, &c., a sailing vessel could

always carry the outward mails westward, when breezes hold, with

almost the same rapidity as steamers; and in her course westward, such

a sailing vessel could scarcely fail to meet a return or a spare

steamer at some of the stations, to relieve it from proceeding

further.

Moreover, it may be observed here, once for all, that by the

conveyance of the mails from Falmouth to Barbadoes by steam, or even

only so far as from Falmouth to Fayal by this power, the irregularity

of the arrival of the mails at Barbadoes, which at present takes

place, would be nearly done away, and consequently no such assistance

as that alluded to would be necessary. Hence, the advantages either

way over the present system are clear and obvious.

Before entering upon the particular details of the West Indian

department, it is proper to observe here, that the point of

communication for the return mails from the West Indies for Europe, so

long as sailing packets are employed to the West Indies, cannot be

altered or removed from Cape Nichola Mole, because, by the general

plan, the outward mails from Great Britain, by steamers, would reach

Fayal on the 10th and 25th of each month, and the return mails to that

place would reach, from Rio de Janeiro, on the 9th and 24th; from New

York and Halifax on the 7th or 8th, or 22d or 23d; and from Barbadoes,

&c., allowing only sixteen days in the Colonies, on the 10th and (p. 034)

25th (App. No. 1.); if brought by sailing packets on dates to

correspond; so that there is not time to spare, the West Indian mail

being the last to reach the central point, and it would be very

detrimental to have any detention of the general mails at this point.

To make Jamaica the central point for the European mails, would

require several days additional; for once at Jamaica the packet would

take eight or ten days to get up and through the windward passage,

which to a sailing packet, notwithstanding this difficulty, is still

the best. In fact, if the mails from Havannah to Demerara are detained

in the West Indies more than sixteen, or at most seventeen days,

beyond the time that these could, by care and exertion, be easily

despatched from thence, the transmission of letters by private ships

to every quarter will most unquestionably be resorted to; and thus the

Post-office revenue suffer severely.

The capital and expenditure in the West Indian department under the

combination and regulations just mentioned will be:--

Capital. Yearly Charges.

Six Steamers, at 24,000_l._ £144,000 £37,200

Nine Sailing Schooners, at 1500_l._ 13,500 7,200

Coals for Steamers, 30,000 tons, at 25_s._ 37,500

------- ------

£157,500 81,900

------- ------

It is necessary here to observe, that the calculation taken for the

consumption of coals is founded upon the basis that the coals are of

the very best quality, and also that the machinery is of the best and

most economical description and construction, and for a vessel of

240-horse power. The time that the steamers are considered to be

engaged in actual work is calculated to include the time passed in

getting up the steam in each voyage, and also to cover all temporary

stoppages. The time allowed on every route and station is, on the

average, more than will be required. Steamers of the force mentioned

will, in good weather and light breezes and seas, even when contrary,

run ten geographical miles per hour; and, within the tropics, with

trade-winds and currents in their favour, at a still greater

speed: but the average performance may be fairly taken at 200 (p. 035)

geographical miles each twenty-four hours, although in all the

climates within the variable winds, and in the tropics when going

against the winds and currents, the speed made good will be, and is

taken at, much less. Moreover it is proper to observe, on the point of

outlay for coals, that the work is everywhere, as regards the quantity

to be used, calculated as if wholly done by steam, while it is obvious

that the assistance of sails may be had recourse to with advantage.

For this purpose, those steamers which have to go into the torrid zone

ought to be provided with large square fore-sails. The assistance to

be obtained by the use of sails would save a considerable quantity of

coals; or what is the same thing, using them would expedite the

steamer proportionally more on her voyage, and bring it so much sooner

to a close. Sails may fairly be calculated to impel a vessel at the

rate of 2-1/2 miles per hour on a voyage, and which will save either

directly _one-fourth_ the quantity of coals, or impel the steamer so

much sooner to the end of her journey than the time calculated, where

time is taken as if it were impelled by steam alone, and thereby a

proportional saving of fuel will be effected. The saving effected on

this ratio will, on the General Plan, be 27,000 tons, 33,250_l._; on

the West Indian portion thereof 7500 tons, 9375_l._; and on the West

Indian and the Falmouth and Fayal department, 9600 tons, 11,475_l._;

subject to 10 per cent. deduction, being allowance for wastage.

As regards the calculations made concerning the progress of steamers

in the voyages to be made, it is satisfactory to find, from

intelligence lately received, that the _Berenice_ steamer, of

230-horse power, made the passage from Falmouth, by the Cape Verdes,

Fernando Po, the Cape of Good Hope, and the Mauritius, to Bombay, in

eighty-eight days; _sixty-three at sea_. The course taken, and

distance run, is about 12,200 geographical miles, or at the average

rate of 194 geographical miles per day. Her average consumption of

coals was fifteen tons per day. The _Atalanta_ of 210-horse power, ran

the same distance in 106 days; sixty-eight of which at sea, under

steam. Consumption of coals, seventeen tons per day. The _Flamer_

steamer, of 140-horse power, now in the West Indies, two voyages (p. 036)

in succession, last autumn, made the voyage from Barbadoes to Jamaica,

by Jacmel, Hayti, in five days; which is fully nine geographical miles

per hour; and in returning she ran in one voyage from St. Lucia to

Barbadoes in twelve hours, distance 100 geographical miles, with winds

and current unfavourable. Adverting to these facts, it is obvious that

sufficient time is allowed for the progress of the steam-boats, in

every station, under the General Plan now recommended to be adopted,

in order to communicate with the different places in the Western

World. The _Berenice's_ greatest run was 256 miles in twenty-four

hours.[3]

[Footnote 3: See also Appendix, No. 1.]

_West Indian Station._--_Details._

This is a complicated and important department, and the working

details thereof must be planned as follows:--

1.--_First Packet for the Month_.

Immediately on the arrival of this packet at Barbadoes, a steamer of

240-horse power should start for St. Thomas direct (430 miles), with

the mails from England, &c. for that island, Santa Cruz and Tortola,

and for Porto Rico, St. Domingo, the Bahamas, All Cuba, Jamaica,

Carthagena, Chagres, Panama, Honduras, Vera Cruz, and Tampico. This

boat could reach and clear St. Thomas in two days.

The steamer alluded to having landed the mails for St. Thomas, St.

Cruz, and Tortola, should then proceed to St. John's, Porto Rico, and

there land the British and Colonial mails; to Cape Nichola Mole

(Hayti), and there land the British, the Colonial, and the Bahama

mails; to St. Jago de Cuba, and there land the British and Colonial

mails; to Kingston, Jamaica, and there land the British, the Colonial,

the Chagres and Carthagena mails; to Savannah la Mar, Jamaica, and

there land the British and Colonial mails for all the western parts

of Jamaica,[4] for Trinidad de Cuba and Honduras; and thence to (p. 037)

Havannah, with the mails for that place, and Vera Cruz, &c.

[Footnote 4: To touch at Savannah la Mar would

scarcely take up one hour, while doing so would be

a very great accommodation to the western part of

Jamaica.]

At the end of the second day this steamer may start on her return,

with the return mails from the Havannah, and the return mails from the

preceding packet from Vera Cruz and Tampico, forwarded and brought up

as after mentioned, and, proceeding, call at Savannah la Mar for the

same, from the western parts of Jamaica, Trinidad de Cuba, and

Honduras; at Kingston for the general Jamaica mails, and those from

Santa Martha, Carthagena, and Chagres from the same packet, and from

Panama, &c. from the preceding packet; at St. Jago de Cuba for the

return mails, and thence to Cape Nichola Mole, where it will deliver

the whole European mails to the packet arrived there, as will

presently be pointed out; from Cape Nichola Mole the steamer will

proceed to St. Thomas, calling at St. John's, Porto Rico, with and for

Colonial mails, and thence to Barbadoes (calling at all the Islands

going up, and carrying up the British mail for Tortola from St.

Thomas, left by the downward steamer) to wait to receive a following

mail from Great Britain.

On the arrival of the downward steamer at Cape Nichola Mole, from St.

Thomas, a fast-sailing schooner to be despatched to Nassau with the

Bahama mails, calling, in going and returning, at Crooked Island. This

schooner, it is calculated, could be back at Cape Nichola Mole in time

to meet the packet at her departure for England with the return mails;

if it could not, then the packet could take Crooked Island in her way,

and there pick up the Bahama return mails for Great Britain.

Two schooners would be sufficient for this station for the Bahama

service, should it be desirable that these islands should have mails

twice each month.

On the arrival of the steamer at Kingston, Jamaica, with the outward

mails, another steamer to be despatched with the mails for Santa

Martha, Carthagena, Chagres, and Panama, calling at Chagres first, (p. 038)

and with the return mails from Panama, the South Sea, and Chagres,

return to Kingston by Carthagena and Santa Martha. One powerful

steam-boat would be in time for the same packet; thus:--to Chagres,

550 miles, two and a half days; to Carthagena, 290 miles, one and a

half day; stop there one day; to Santa Martha, ninety miles, one day;

to Jamaica, 420 miles, three days; in all, nine days.

The mails for Honduras and Trinidad de Cuba by the outward packet

having been brought up to Montego Bay, Jamaica, as has been already

stated, a good schooner should proceed thence to Trinidad de Cuba, 172

miles, one and a half days; thence to Honduras, 520 miles, three and a

half days; stop three or more days; back to Montego Bay, by Trinidad

de Cuba, 692 miles, ten days; in all, eighteen days. Two schooners

will perform this work, giving two mails each month.

On the arrival of the steamer at Havannah another steamer should be

despatched with the outward mails for Tampico and Vera Cruz, and from

thence return to Havannah with the return British and Colonial mails.

The course of this boat would be,--to Vera Cruz, 800 miles, three and

a half days; to Tampico and back, 360 miles, stopping two days, four

days; Vera Cruz, back to Havannah, five and a half days; in all,

thirteen days.

The route of the mail conveyance from Barbadoes to Jamaica, &c., by

steamers, would therefore be:--

Geo. Miles. Days.

Barbadoes to St. Thomas 430 2

St. Thomas to Jamaica, by Porto Rico, Cape Nichola,

and St. Jago de Cuba 780 3-1/2

Jamaica to Havannah, by Cape Antonio 685 3

Stop at Havannah 2

Havannah to Jamaica, by Cape Antonio 685 4

Jamaica, Coals 1

Kingston to Cape Nichola Mole, by St. Jago 305 2

Cape Nichola Mole to St. Thomas, by P. Rico 480 3

St. Thomas, Coals 1

St. Thomas to Barbadoes, calling at all Islands 500 4
