our wheels." 
•' The Glasgow may be 100 tons larger, fat bot-

Common wheels.” 
In this iiisiance Ihe admirers of modeiatc sized 
vessels and large power will tind they aie beaien

“ Dba R s I Bj— i send you at foot, an exiiact of a

“ Gentlkmkn,— 1 wiiie to infotm )ou that Ihe 
an iveil at this port (Lisbon) on Eiiday 
evening, in four days from Falnioiiih, against stiong 
contraiy winds, with a heavy sea. Ihe Engines 
peifoiiii very beautifully. 1 have not had any tiou- 
ble with Ihein at <11 The cojiper pipes answer the 
purpose veiy well, and we are now quite conifoita- 
ble in the En<giiie decarinient. We beat the Glas- 
gow Steainer 40 hoiiis ironi i'altnouth; both vessels 
left Falmouth.” 
“ The distance from Falmouth to Lisbon is 728 
nautical miles, being 46.j lo cape Fiuisire, 254 mote 
to the month of the I agiis, and Lisbon is siiuaied 9 
miles inside ilie entiance of the river. 1 he Tran, 
sit tlieiefoie made good, under ilie cii ciitiislances 
detailed in the letters quoted above, knots in 4 
days, being 162 miles per diem, or "^-12 knots per 
hour for the wliole dist ance. I liis would have been 
a very good aveiage spied, even with fine weather 
and fan winds, hot when it is stated to have lieen 
against a heavy sea and strong contrary wind, it is 
indeed excellent. 
With this example before ns, 1 think no reasona- 
ble man, can doniii the pel ft-ct fiiness of vessels of 
the same <lescii|ilioii as ilie Transit for keeping up 
a steam communication between Uoinbay and 6mz • 
for it is Cel lain ibat a vessel sufficiently poweifnl to’ 
cioss the Bay of Biscay against a conliaiy wind and 
heavy sea, at the late of ?JL.knots pei hour, could 
always average alleast ihe^ame speed with any 
vveailiei she is likely lo eiic<juuier in the Indian seas 
lot 9 months in the year. 
It ha\ iiig been thus ascertained that a vessel of 
such modeialesize and power is fully sufficient for 
keeping up steam cotninunicaiion, it now onl\ re- 
mains to estimate the cost and circonisiaiices* un- 
der which ihiee vessels of this desciiplioii could he 
placed ill Boniltay baiboiir, ready for use, and 
wiwl Would be iheii expeiices in luniiing inonthly 
Irips fur 9 mouths in the year. 
The first point is to asceriain what would be the 
ptiine cost of three such vessels, and to do this Sir 
Piilieny Malcolm’s and Mr. ftlorgan’s evidence be 
fore ibe commiiiee of ihe House of Commons 
aff.iid the necessary data upon which tiie following 
estimate has Iteeii fiaiued, and to which, in order 
to tnsuie its being tiiliy sullicient to cover every 
possible outlay, I have added 10 per leiit. foi coii- 
tiugeiicies, after eveiy item, including one spate set 
of copper boilers, has been provided for. 
Outline Estimate of expence of procuring from 
England three Steam Vessels, each 300 tons 
burden atid fitted with a pair o/’40 horse pow

N. B. — Sir Pulteny MalcoLn estimates ihe total 
cost ol 3 vessels of 433 tons each, and lOo horse 
power with duplicate (laits &c. built in England 
and sailed out lu Bo.iibay only at £6 1,600, so that 
the above estimate must be amply sufiicieni to cover 
every item of piime cost. 
The next point for consideration is theexpenc® 
ofinniiiiig such vessel; and on this point also 
there is much valuable iiifoiitialioii in the evitleiice 
of Sir I’lilteiiy Malcolm and Mi . Morgan ; and in 
Ollier lespccis where their estimates are too low, 
I have foniiiiately by me Hie immibly expeiiceof 
Ihe Hon’hle Company’s Sleaiuer//rfli/r;«r/y, a vessel 
of the same size and power as lltose now proposed j 
and this I have assumed as a settle for ineusuiiii" the 
expence of wages to the establislimeut. 
The next item is the quantity of coal which would 
be coiisunied and its cost.— In 01 dei to asceiiain this 
it is necessary to estimate Hie number of hoiiis dur- 
ing which each vessel must be under steam in each 
passage.- It would in every respect be most desira- 
ble, in Older lo economise in liiis respect, to divide 
the distance mote equally than is effecied by the 
present arrangt-iiient of dep6ts, and this from iafoi- 
III nion which 1 liave lately received seems exceed" 
iiigly feasible. Hi<lainea-ihe largest of the Ciiria- 
Muiia islands — has safe aiichoiage dtiiiiig both 
iiioiisootis, and is only about 950 miles from Bom. 
bay. — Cainaiaii, ail island a shoit distance wiihiu ihe 
siiaits of Bahelmamlel, has an exceedingly good 
harbour and plenty of water. It is about 970 miles 
fioiii Hiilaiiiea.-Fidin caniarau island to Suez is 
about 1000 miles, and might form the thiid stage, 
coal being deposited at .Suez from Alexandria for 
the reiiiiu nip. — Ktckoiiing an average of only 7 
knots per lioiii , each of these stages would be com- 
pleted in (5 days at the veiy utmost, or each vessel 
would make the trip to Suez in 18 day sunder steam- 
and reckoning by Hie passage of the Transit, would 
no douhi, under favorable circiinistances, compiete 
Ihe Hip wiihiii 16 days steaming. -Tivo days slop, 
page at each depot would complete Hie passa>e in 
23 and 20 day s fioni Bomhav.— lleckoiiii,<» 18 day# 
under steam, each vessel with an 80 hoise power 
would consume 84 tons of coal per diem, or about 
150 tons for a single passage, being for 18 passa-ea 
2,;00 tons, and allowing 10 per cent for waMe 
It would require about 3t>00 tons coal per anniini 
to make 9 moiiHily double trips with vessels iich 
as those in question. -Supposing coal to cost in 
Bombay 13 Hiipees per ton, and I have reason to 
believe that it coyld beliad, under proper arraii»a- 
nients, at 12 Rupees, and supposing the cost in tlie 
Bed Sea lo be 23 per too, it give an aveia-e 
Ihroiighoiit, of Hiipees 20 per ton as Hie priccof 
coal, at which cost 1 have reckoned in the annexert 
estimate.
