This is stowed, as heretofore, in the three immense iron tanks, built up from tho main deck, one forward, one amidships, and one aft of the vessel. The weight of these tanks and the water in them is upwards of 1000 tons, and in addi tion the Great Eastern will carry 8500 tons of coal, 500 tons of telegraph stores and machinery, and 4000 tons of cable—a dead-weight cargo of more than 14,000 tons in all, exclusive of engines, rig, and all ship's fittings, which will amount to nearly as much more. Thje, however, only brings the vessel down to her fair load-line—in fact, into the perfect trim in which she left last year, when the utmost swell of an. angry Atlantic sea could do little more than make her dip occa sionally among its rugged furrowf. It has been thought advisable, how ever, considering the Great Eastern's depth in the water, and the somewhat shallow channels she will have to pass on her way to the river's mouth, not to put all the coals in her before she leaves Sheerness. At Beerhaven, therefore, 2500 tons will be taken on board beforo she starts for Valentia, and after joining the shore-end steams away on her adventurous voyage across the Atlantic. Except, then, in this matter of coals she will leavo the Thames completely equipped. Among her stores are 20 miles of grappling ropo of the most powerful kind that can be made, and equal to a strain of 30 tons. She also carries five miles of rope equal to a strain of 11 tons,' with quite a collection of buoys, grappling irons, slip ropes, &c. But at the stem and stern are fitted two powerful little engines, made by Messrs. Penn, each of which works up to 80-horse power. These are connected with the paying out and hauling-iu apparatus. Both these latter have been slightly im

proved since last year, and have been made as light as possible consistent with the work they have to do. Cer tainly, the hauling-iu powors of the engines are likely to bo much in excess of what is required to be dono. Last yoar their efforts fell short of what is required to he done. With the Great Eastern on Saturday noxt will also start Her Ma jesty's steamship Terrible, 21, and the steamers William Corry, Albany, and Medway.
