The passenger accommodation in the _Great Eastern_ is very extensive-- namely, 800 first-class, from 2000 to 4000 second-class, and about 1200 third-class passengers; or if troops alone were taken, it could accommodate 10,000 men. The _saloons_ are fitted up in the most elaborate and costly manner. The chief saloon is magnificently furnished. It is said that the mirrors, gilding, carpeting, and silk curtains for this apartment alone cost 3000 pounds. In the berths, of course, no attempt is made at costly decoration of this kind, though the fittings are good and sufficiently luxurious. The berths are arranged in three classes: those for parties of six or eight, and these are large rooms; those for parties of four; and the rest in the usual style of double cabins. All are very roomy, as cabins go--very lofty, well lit, and those on the outer sides exceedingly well ventilated. On the lower deck the berths are even larger, loftier, and more commodious than those on the upper. Both the berths and saloons here are in fact almost unnecessarily high, having very nearly fifteen feet in the clear. The kitchens, pantries, and sculleries are all on the same extensive scale, and fitted with all the large culinary requisites of first-class hotels. The ice-house holds upwards of 100 tons of ice; and the lofty wine-vaults--for such in fact they are--contain wine enough to form a good freight for an Oporto trader. _Miscellanea_.--In addition to the boats of the _Great Eastern_ (twenty in number), she carries two small screw-steamers, each 100 feet long, 16 feet broad, 120 tons burden, and 40 horse-power, suspended aft of the paddle-boxes. As the captain's voice could not be heard half-way to the bow, even with the aid of the ancient speaking-trumpet, that instrument is supplanted by _semaphore_ signals by day, and _coloured_ lamps by night; the _electric telegraph_ is also used in connection with the engine-rooms. There are ten _anchors_, four of them being Trotman's patent, weighing seven tons each. The _cables_ are each 400 fathoms long, and their united weight is 100 tons. The _tonnage_ of the _Great Eastern_ is 18,500 tons register, and 22,500 tons builders' measurement. The _crew_ at first consisted of thirteen officers, seventeen engineers, a sailing-master, and a purser, four hundred men, and two or three surgeons, all under the command of the late Captain W. Harrison, (formerly of the Cunard line).
