Early in September, 1833, the locomotive “John Bull” was put on the train leaving Bordentown about 7 o’clock in the morning, and returning leaving South Amboy at 4 P.M.  This was the first passenger train regularly run by steam on the route between New York and Philadelphia.

THE BRITISH CRUISER AEOLUS.

The new twin screw cruiser AEolus was launched from the Devonport Dockyard on the 13th November.  The first keel plate of the AEolus was laid in position on the 10th March last year, and up to the present time fully two thirds of the estimated weight has been worked into her structure.  Says Industries:  She is built of steel, with large phosphor bronze castings for stern post, shaft brackets, and stem, the latter terminating in a formidable ram.  The hull is sheathed with wood, and will be covered with copper to enable her to keep the seas for a lengthened period on remote stations, where there is a lack of docking accommodation.  All the vital portions, such as machinery, boilers, magazines, and steering gear, are protected by a steel deck running fore and aft, terminating forward in the ram, of which it virtually forms a part.  Subdivision has been made a special feature in this type of vessel, and the hull under the upper deck is divided into nearly 100 water tight compartments.  Between perpendiculars the AEolus measures 300 ft. in length, the extreme breadth being 43 ft. 8 in., and moulded depth 22 ft. 9 in., with a displacement of 3,600 tons on a mean draught of water of 17 ft. 6 in.  She will be supplied by Messrs. Hawthorn, Leslie & Co., of Newcastle on Tyne, with two sets of vertical triple-expansion engines, capable of developing collectively 9,000 h.p., which is estimated to realize a speed of 19.75 knots.  As vertical engines have been adopted, the necessary protection of the cylinders, which project above the steel protective deck, is obtained by fitting an armored breastwork of steel 5 in. thick, supported by a 7 in. teak backing, around the engine hatchway.  Provision is made for a bunker coal capacity of 400 tons, and this is calculated to give a radius of action of 8,000 knots at a reduced speed of 10 knots.  The armament of the ship will consist of two 6 in. breech-loading guns on central pivot stands, one mounted on the poop and another on the forecastle; six quick-firing 4.7 in. guns, mounted three on each broadside; eight quick-firing 6-pounder guns, four on each broadside; besides one 3-pounder Hotchkiss and four 5-barrel Nordenfeldt guns.  In addition four torpedo tubes are fitted, one forward, one aft, and one on each broadside.  All the necessary appliances for manipulating the engines, guns, steering gear, etc., when in action, are placed in a conning tower built of steel 3 in. thick, and situated at the after end of the forecastle.  The AEolus will be rigged with two pole mast, carrying light fore and aft sails only.  Her total cost
