saloon and entire range of cabins were lighted by gas; made on

board; though this has since given place to the incandescent

electric light。  A fine promenade deck was provided over the

saloon; which was accessible from below in all weathers by the

grand staircase。



These; and other arrangements; greatly promoted the comfort and

convenience of the cabin passengers; while those in the steerage

found great improvements in convenience; sanitation; and

accommodation。  〃Jack〃 had his forecastle well ventilated and

lighted; and a turtle…back over his head when on deck; with

winches to haul for him; and a steam…engine to work the wheel;

while the engineers and firemen berthed as near their work as

possible; never needing to wet a jacket or miss a meal。  In

short; for the first time perhaps; ocean…voyaging; even in the

North Atlantic; was made not only less tedious and dreadful to

all; but was rendered enjoyable and even delightful to many。 

Before the Oceanic; the  pioneer of the new line; was even

launched; rival companies had already  consigned her to the

deepest place in the ocean。  Her first appearance in Liverpool

was therefore regarded with much interest。  Mr。 Ismay; during the

construction of the vessel; took every pains to suggest

improvements and arrangements with a view to the comfort and

convenience of the travelling public。  He accompanied the vessel

on her first voyage to New York in March; 1871; under command of

Captain; now Sir Digby Murray; Brt。  Although severe weather was

experienced; the ship made a splendid voyage; with a heavy cargo

of goods and passengers。  The Oceanic thus started the

Transatlantic traffic of the Company; with the house…flag of the

White Star proudly flying on the main。



It may be mentioned that the speed of the Oceanic was at least a

knot faster per hour than had been heretofore accomplished across

the Atlantic。  The motion of the vessel was easy; without any

indication of weakness or straining; even in the heaviest

weather。  The only inducement to slow was when going head to it

(which often meant head through it); to avoid the inconvenience

of shipping a heavy body of 〃green sea〃 on deck forward。  A

turtle…back was therefore provided to throw it off; which proved

so satisfactory; as it had done on the Holyhead and Kingstown

boats; that all the subsequent vessels were similarly

constructed。  Thus; then; as with the machinery; so was the hull

of the Oceanic; a type of the succeeding vessels; which after

intervals of a few months took up their stations on the

Transatlantic line。



Having often observed; when at sea in heavy weather; how the

pitching of the vessel caused the weights on the safety…valves to

act irregularly; thus letting puffs of steam escape at every

heave; and as high pressure steam was too valuable a commodity to

be so wasted; we determined to try direct…acting spiral springs;

similar to those used in locomotives; in connection with the

compound engine。  But as no such experiment was possible in any

vessels requiring the Board of Trade certificate; the alternative

of using the Camel as an experimental vessel was adopted。  The

spiral springs were accordingly fitted upon the boiler of that

vessel; and with such a satisfactory result that the Board of

Trade allowed the use of the same contrivance on all the boilers

of the Oceanic and every subsequent steamer; and the contrivance

has now come into general use。



It would be too tedious to mention in detail the other ships

built for the White Star line。  The Adriatic and Celtic were made

17 feet 6 inches longer than the Oceanic; and a little sharper;

being 437 feet 6 inches keel; 41 feet beam; and 32 feet hold。 

The success of the Company had been so great under the able

management of Ismay; Imrie and Co。; and they had secured so large

a share of the passengers and cargo; as well as of the mails

passing between Liverpool and New York; that it was found

necessary to build two still larger and faster vesselsthe

Britannic and Germamic: these were 455 feet in length; 45 feet in

beam; and of 5000 indicated horse…power。  The Britannic was in

the first instance constructed with the propeller fitted to work

below the line of keel when in deep water; by which means the

〃racing〃 of the engines was avoided。  When approaching shallow

water; the propeller was raised by steam…power to the ordinary

position without any necessity for stopping the engines during

the operation。  Although there was an increase of speed by this

means through the uniform revolutions of the machinery in the

heaviest sea; yet there was an objectionable amount of vibration

at certain parts of the vessel; so that we found it necessary to

return to the ordinary fixed propeller; working in the line of

direction of the vessel。  Comfort at sea is of even more

importance than speed; and although we had succeeded in four

small steamers working on the new principle; it was found better

to continue in the larger ships to resort to the established

modes of propulsion。  It may happen that at some future period

the new method may yet be adopted with complete success。



Meanwhile competition went on with other companies。  Monopoly

cannot exist between England and America。  Our plans were

followed; and sharper boats and heavier power became the rule of

the day。  But increase of horse…power of engines means increase

of heating surface and largely increased boilers; when we reach

the vanishing point of profit; after which there is nothing left

but speed and expense。  It may be possible to fill a ship with

boilers; and to save a few hours in the passage from Liverpool to

New York by a tremendous expenditure of coal; but whether that

will answer the purpose of any body of shareholders must be left

for the future to determine。



〃Brute force〃 may be still further employed。  It is quite

possible that recent 〃large strides〃 towards a more speedy

transit across the Atlantic may have been made 〃in the dark。〃



The last ships we have constructed for Ismay; Imrie and Co。 have

been of comparatively moderate dimensions and powerthe Arabic

and Coptic; 430 feet long; and the Ionic and Boric; 440 feet

long; all of 2700 indicated horse…power。  These are large cargo

steamers; with a moderate amount of saloon accommodation; and a

large space for emigrants。  Some of these are now engaged in

crossing the Pacific; whilst others are engaged in the line from

London to New Zealand; the latter being specially fitted up for

carrying frozen meat。



To return to the operations of the Belfast shipbuilding yard。  A

serious accident occurred in the autumn of 1867 to the mail

paddle…steamer the Wolf; belonging to the Messrs。 Burns; of

Glasgow。  When passing out of the Lough; about eight miles from

Belfast; she was run into by another steamer。  She was cut down

and sank; and there she lay in about seven fathoms of water; the

top of her funnel and masts being only visible at
