The hull of the “Great Eastern” is proof against the most formidable seas; it is double, and is composed of a number of cells placed between the deck and hold; besides these, thirteen compartments, separated by water-tight partitions, increase the security against fire or the inlet of water. Ten thousand tons of iron were used in the construction of this hull, and 3,000,000 rivets secured the iron plates on her sides. The “Great Eastern” draws 30 feet of water with a cargo of 28,500 tons, and with a light cargo, from 20 to 30 feet. She is capable of receiving 10,000 passengers, so that out of the 373 principal districts in France, 274 are less populated than this floating sub-prefecture with its average number of passengers. The lines of the “Great Eastern” are very elongated; her straight stem is pierced with hawse-holes, through which the anchor-chains pass; no signs of dents or protuberances are to be seen on her finely-cut bows, but the slight sweep of her rounded stern somewhat mars the general effect. From the deck rise six masts and five chimneys. The three masts in front are the “fore-gigger” and the “fore-mast” (both of them mizen-masts) and the “main-mast.” The last three astern are the “after-main-mast,” “mizen-mast,” and “after-gigger.” The fore-masts and the main-masts carry the schooner-sails, the top-sails, and the gallant-sails; the four other masts are only rigged with ordinary sails; the whole forming 5400 square yards of good canvas. On the spacious mastheads of the second and third masts a band of soldiers could easily manœuvre. Of these six masts, supported by shrouds and metallic back-stays, the second, third, and fourth are made of sheet-iron, and are really masterpieces of ironwork. At the base they measure 43 inches in diameter, and the largest (the main-mast) rises to the height of 207 French feet, which is higher than the towers of Notre Dame. As to the chimneys, the two belonging to the paddle-engine and the three belonging to the screw, they are enormous cylinders, 90 feet high, supported by chains fastened to the upper deck. The arrangements with regard to the interior are admirable. The laundries and the crew’s berths are shut off at the fore-part, then come the ladies’ saloon and a grand saloon ornamented with lustres, swinging lamps, and pictures. These magnificent rooms are lighted by side skylights, supported on elegant-gilded pillars, and communicate with the upper deck by wide staircases with metallic steps and mahogany balusters. On deck are arranged four rows of cabins separated by a passage, some are reached by a landing, others on a lower story by private staircases. At the stern the three immense dining-rooms run in the same direction as the cabins, a passage leads from the saloons at the stern to those at the bows round the paddle-engine, between its sheet-iron partitions and the ship’s offices.
