IV.--OCEAN STEAMERS.

In the quarter of a century which elapsed between 1812, when the _Comet_

first began to churn the waters of the Clyde, and 1837, steam navigation

progressed steadily and surely. At first, content with plying along

rivers and quiet bays, steamers by-and-by ventured out upon the open

sea. We owe the regular establishment of deep-sea packets to the courage

and enterprise of Mr. David Napier of Glasgow, "who," says Mr. Scott

Russell, "has effected more for the improvement of steam navigation than

any other man." He was quick to appreciate the capabilities of

steam-vessels, and saw that they were fit for something more than mere

inland voyages. Before starting one of them upon the open sea, however,

he carefully estimated the danger to be encountered and the difficulties

to be overcome. He took passage at the worst season of the year in one

of the sailing vessels which formerly plied between Glasgow and Belfast,

and which often required a week to perform a journey that is now done by

steam in a few hours.

Stationing himself on an elevated part of the deck, he kept a close

watch on the movements of the vessel, observing the tossing to which she

was subjected by the waves, the extent of the dip when she sank into a

trough, the height of elevation when lifted on the summit of a wave, and

calculating in his mind how all this would tell on the paddle-wheels.

Through the roughest of the storm, when the vessel was pitching worst,

and the wind blowing at its fiercest, he kept his place on deck,

regardless of the drenching spray and the blast that almost carried him

off his legs. When at length he had satisfied himself by the observation

of his own eyes and inquiries of the captain and crew, that there was

nothing in the voyage which a steamer could not encounter, he retired

contentedly to his cabin, leaving everybody astonished at his strange

curiosity respecting the effect of rough weather on the ship.

Not long after David Napier started the _Rob Roy_ steam-packet between

Greenock and Belfast, and afterwards between Dover and Calais. In the

course of two or three years more he had established steam communication

between Holyhead and Dublin, Liverpool and Greenock, and various other

parts. The length of each unbroken passage was then considered the great

difficulty; but as steamers got improved both in form and machinery,

passages of greater length were successfully accomplished. Steamers

traversed in all directions the German Ocean, the Mediterranean, the

Baltic, and, in short, all the waters on the eastern side of the

Atlantic; and were in use upon all the rivers and lakes of any size in

Europe.

At length, in 1836, the startling project was set on foot of superseding

the far-famed New York and Liverpool packet ships by a fleet of

steam-ships. Before this the _Savannah_, a steam vessel of 300 tons,

had, in 1819, crossed from New York to Liverpool in twenty-six days,

partly with sails and partly with steam; and another steam vessel had,

in 1825, made the voyage from England to Calcutta; but one swallow does

not make a summer, and many learned folks, on both sides of the

Atlantic, shook their heads doubtfully at the daring scheme of regular

steam communication across 13,000 miles of ocean. The experiment was to

be made, however; and on the 4th April 1838, the _Sirius_, of 700 tons

and 320 horse power, sailed from Cork for the far West. Four days after

the _Great Western_ followed in her wake from Bristol.

Great was the excitement in New York as the time drew nigh when the

_Sirius_ was considered due. For days together the Battery was crowded

with anxious watchers, from the first breaking of the cold, grey dawn

till night dropped its dark curtain on the scene. At that time a

telescope was a thing to be begged, borrowed, or stolen,--to be got,

somehow or other, if only for a minute,--and a man who possessed one was

to be looked up to, made much of, and, if possible, coaxed out of the

loan of it. All day long a hundred telescopes swept the sea. The ocean

steamer was the great topic of the hour, and "any appearance of her?"

the constant question when two people met. On St. George's day, the 23d

April, a dim, dusky speck on the far horizon grew under the eye of the

thousands of breathless watchers into a long train of smoke, beneath

which, as the hours wore on, appeared the black prow of a huge

steam-boat. There she was, long looked for come at last; and with the

American colours at the fore, and the flag of Old England rustling at

the stern, the _Sirius_ swept into the harbour amidst the cheers of the

multitude, the ringing of the city bells, and the firing of salutes. The

excitement reached its climax, and the shouting and firing grew

deafening, when, some few hours later on the same auspicious day, the

_Great Western_ came to anchor alongside of her rival.

Twenty-two years have passed since then, and the marvel of 1838 has

become a mere everyday affair. There are some fourteen different lines

of steamers, comprising more than fifty vessels, running between the

United States and Europe, to say nothing of the magnificent steam fleets

of the Peninsular and Oriental, the Royal West India, British and North

American, Pacific, Australian, South Western, and other companies.

The employment of iron in the construction of ships, thus securing at

once lightness and strength, and the invention of the screw propeller,

in 1836, by Mr. J. P. Smith, a farmer at Hendon, by means of which a

vessel can combine all the qualities of a first-rate sailing ship with

the use of steam power, gave a great impulse to steam navigation, which

is still making steady and continuous progress. From one steam vessel

in 1812 the number in the kingdom has risen successively to 20 in 1820,

824 in 1840, and over 2000 in 1860. During 1858, 153 steamers were built

in the United Kingdom, of which 112 were of iron. It is interesting to

observe the advance in size of the steam vessels from their first

introduction on the Clyde.

Length. Breadth.

1812. Comet 40 feet 10-1/2 feet.

1825. Enterprise (built expressly to go to

India, coaling at intermediate

stations) 122 " 27 "

1835. Tagus (for Mediterranean) 182 " 28 "

1838. Great Western (the first ship built

expressly for Transatlantic service) 236 " 35-1/2 "

1844. Great Britain (the first large screw

ship, and largest iron ship up to that

time) 322 " 51 "

1853. Himalaya (iron) 370 " 43-1/2 "

1856. Persia (do.) 390 " 45 "

1859. Great Eastern (do.) 680 " 83 "

In the interval between 1812 and 1870 the number of steamers in the

United Kingdom has increased from one to nearly three thousand; and the

ocean-going steamer of 1870 is nearly six times the length of that of

1825, and seventeen times the length of the _Comet_, while the

difference in tonnage is still greater. How Fulton or Bell would open

their eyes at the sight of a vast moving city, such as the Big Ship, an

eighth of a mile in length, propelled by both paddle-wheels and screw,

each worked by four huge engines!
