But the machinery employed at Crewe seems capable of cutting any thing, even though it were a rock of adamant. You pass into a shed full of little machines, standing separate from each other, with all manner of curious wheels and belts, driven by steam, of course, and each with a man stationed by its side, gazing attentively at the little machine, as if he were absorbed in thought; and, indeed, were it not for an occasional quick movement of his hands, and a rapid change of position, you might almost suppose that he was sleeping on his legs. But go close up, and you notice that the machine is slowly moving backward and forward, and still more slowly at the same time in a lateral direction. Some curious piece of mechanism is placed on it, and the movements of the machine cause a sharp steel-cutter to pass over the iron surface, which cuts it as easily and truly as a joiner planes a piece of fir. The side motion brings all the surface gradually under the instrument, but the machine, clever and powerful though it is, requires to be constantly watched and regulated, and hence the fixed attention of the man in charge. At a large machine, you will see those long, curious rods called "eccentrics" undergoing this operation; at another, a cylinder is being planed; and at a third, the rims of wheels are being cut. The filings thus made are preserved, and will be seen in large heaps in a yard, ready to be melted down, and "used up" again. In some cases both iron and brass filings are produced, which, of course, are mixed with each other; but in a quiet corner of one of the sheds you will find a boy with a heap of these filings before him, separating the brass from the iron by means of a magnet. Only imagine a boy of fourteen or fifteen doing nothing all day long except raking a magnet through a heap of black and yellow dust, and brushing into a separate heap the iron filings off his magnet! You will also see a series of three iron rollers working on each other, by means of which plate iron can be twisted into any given form; a mighty "punch" which will make a hole an inch in diameter through iron an inch in thickness as easily as though it were clay; and a sharp-cutting instrument that shears through sheets of iron as easily as a pair of scissors through a sheet of paper.
Go into another shed, and you will see all these various parts getting their last touches from the hand, and being fitted into each other; and here, also you find two or three men engraving, on circular segments of brass, the names the various engines are to be known by. In another shed the engines are being "erected." Here you see from twenty to thirty in all stages of progress. Perhaps the framework only has been laid; or the boiler, with its many rows of long, circular brass tubes, has just been fastened, and is now receiving its outer clothing of long slips of wood; or the whole is complete, merely wanting to be tried on the many lines of rail in and around the sheds. There are two classes of engines here, whose difference is observable at a glance: some have six wheels, two of which are very large, about six feet in diameter, and the other four much smaller. The two first only are driven by the machinery, the others being merely what are called "bearing wheels." With this description of engine more speed than power is obtained, and hence it is used for passenger trains, where a high velocity is required, and where there is usually little weight, comparatively speaking, to draw. The others have only four wheels, not so large as the two just described, but all driven by the machinery. Such engines I are more remarkable for power than speed, and accordingly they are used for luggage trains. In another shed, "The Hospital," will be found a number of engines laboring under various disorders, sent here to be repaired.
But carriages and wagons are also built here. You enter a shed (of two stories this time), and find wood shavings instead of iron filings, and the hissing of a circular saw instead of the quiet, steady scraping of a "cutter." Here all the woodwork of the carriages is executed, and when ready they are hoisted through a large trap-door in the roof to the second story, where they are painted and varnished, and, if first-class, "up-holstered." In a store-room above stairs, are piled heaps of cushions ready for the most expensive carriages; at a table is a boy stuffing with horse-hair the leathern belts that hang by the sides of the windows; and elsewhere an artist is painting the arms of the company on the panels of a door. Here and there are boards placed before a carriage, with the intimation "Wet!" indicating that you must not go too near; and some of the carriages give evidence of having seen service, but are now renewing their youth under the skillful hands of the painter and the upholsterer. When ready to "go on the line," they are let down through the trap-door, fixed on their wheels and axles, and sent to relieve others that require repair.
Six o'clock strikes, and work ceases. In walking back leisurely to the station, I saw many of the workmen digging in their little gardens, "bringing themselves," as Emerson phrases it, "into primitive relations with the soil and nature;" others were reading the papers of the day at the Mechanics' Institution; others strolling among the green fields round the town; and others walking to a class-room, to hear a teetotal lecture; while some were proceeding to recreations of a very different kind. I was admitted through the iron gate by the same policeman; the "down" express train arrived, and it conveyed me in an hour and a half to Liverpool, a distance of about forty-five miles, stopping only once at the well-known town of Warrington.

STEAM-BRIDGE OF THE ATLANTIC.
In the summer of 1838 the Atlantic Ocean was crossed for the first time by vessels exclusively propelled by steam-power. These pioneers were the Sirius and the Great Western—the former built for another class of voyages, and afterward lost on the station between Cork and London; the latter built expressly for Atlantic navigation, and which has ever since been more or less employed in traversing that ocean. Other ships followed: the British Queen, afterward sold to the Belgian government; the Great Liverpool, subsequently altered and placed on the line between Southampton and Alexandria; and the President, lost, no man knows how or where, in the year 1841. Then came what is called "Cunard's Line," consisting of a number of majestic steam-ships built in the Clyde, to carry passengers and mails between Liverpool in Europe, and Halifax, Boston, and New York in America; a service they have performed with the most marvelous regularity. The only great misfortune that has befallen this line has been the loss of one of the vessels, the Columbia, which, in nautical phrase, "broke her back" on some rocks on the American shore of the Atlantic. Then came the Great Britain, the greatest of them all, differing from the others in two respects—first, in being built of iron instead of wood; and second, in being propelled by the Archimedean screw instead of by the old paddle-wheels; and, alas! she has differed from them all in a third respect, inasmuch as neither the same good-luck attended her as in general fell to the lot of the ships of the Cunard Line, nor the same irretrievable bad fortune as was met by the President and the Columbia; for, after having made several voyages very successfully, she, to the amazement of all mankind, very quietly went ashore in Dundrum Bay, on the east coast of Ireland, from whence, after spending a most uncomfortable winter, she was brought back to Liverpool, and now lies in the Bramley-Moore Dock there, like a huge mass of iron suffering under premature rust. But all this time these ocean steamers that periodically brought to New York passengers and intelligence from Europe were British built. They had been constructed in the Avon, the Mersey, and the Clyde, the greater number having been launched in the same waters as first received Henry Bell's little Comet. Why did America not embark in such enterprise? As regards steam navigation, Fulton was before Bell; New York before Glasgow; the Fulton's Folly before the Cornet; and was
"The greatest nation
In all creation"
to be outdone in the field of enterprise by the old Britishers? American pride said "No;" American instinct said "No;" and, above all, American capitalists said "No!" Keels were laid down in New York; the shipbuilders' yards became unusually active; and the stately timbers of majestic ships gradually rose before the admiring gaze of the citizens of the great republic.
