OF THE SOCIETY OF ENGINEERS TO THE nvR STRATFORD September27 a visit Carriage Works at Stratford. These works were ft npned in the year 1847, and now occupy a total 0P na nf 52 acres, of which the shops alone cover 13. 55 number of hands employed is about 4,800. The illincstock consists of 546 tender-engines, 357 tank- Xnes, 3,785 carriages, 16,118 waggons, and 925 road- vans which are renewed and kept xn repair mainly at these works.

The whole of the new stock, averaging enrine, 6 carriages, and 14 waggons per week, is also now built at the Stratford Works; 1,260 carriages are by compressed oil-gas, and all engines and carriages used for passenger trains are fitted with the Westinehouse automatic compressed-air brake. The following is a brief description of thelocomotive department. The erecting shop is 348 feet by 142 feet. It has four bays the two centre ones are used for erecting purposes, ana fifty engines can be in hand at the same time. It was in this shop that a locomotive of the goods-engine type was recently built in ten working hours, being commenced at 9 a.m.

on December 10 and turned out finished at 9.15 a.ni. on December 11, 1891. This engine has not yet been in the shop for repairs. There are four 30-ton and one 15-ton overhead travelling cranes, worked by flying ropes, travelling at a velocity of about 2,200 feet per minute, also four 3-ton hand- cranes. The main portion of the drilling on the pits is done by "Stow" flexible shafts.

There are also portable machines for cutting off tube ends, boring and facing cylinders, facing slide valve-faces, dome tops, and tapping stay holes. The two side bays are used for fitting purposes, boiler mounting, and for heavy machinery, including a frame-slotting machine, radial drills, planing machines, cylinder-boring machines, and a vertical milling machine. In one corner of this shop there is a 50-ton testing machine, fitted with Wickstead's patent self-recording apparatus, which gives stress diagrams of the tests. Bending, compression, and tensile tests are here made of boiler and frame plates, and records kept. Above the southbay is a floor containing the pattern- shop, the chemical laboratory, and the works-manager's drawing office; in the latter of which is a model motion for experimentally setting out and determining the motion of different classes of engines.

In the laboratory tests are made for determining the constituents of iron, steel, and other materials, the calorific value of coal and oil, the properties of water, Above the north bay is a shop in which Westinghouse brake work is fitted up and repaired, and there are also brass finishers, working here. In the machine shop, which is 144 feet by 138 feet, there are 189 machines, comprising lathes, planing, slotting, shaping, drilling, and milling machines, the latter being a special feature. Twist drills are mainly used throughout the establishment. In the iron foundry there are three cupolas, two of about 3 tons capacity each, and one of 7 tons. There are two overhead travelling cranes, one 15-ton hand gear, and one 10-ton, driven by square shaft running the full length of the shop.

About 40 tons of castings are turned out per week. The brass-foundry and coppersmith's shop adjoin the iron-foundry. In the Doiler-shop there are six overhead travelling cranes driven by flying ropes. The greater portion of the riveting is done by means of two fixed and four portable hydraulic riveters, worked by special pumps and accumulators, two of the portable riveters being specially designed for foundation and fire-hole riiigs. There is also a large punching press for engine frame- plates lj-inch thick, and horizontal and vertical plate- bending rolls.

In the flanging shop there are two hydraulic presses for flanging and stamping plates, worked at a pressure of about per square inch, giving on the 20-inch ram of the larqe press a total pressure of about 220 tons. Boiler, firebox, and other plates connected with engines and tender work are flanged here. In the steam-hammer shop stamping by means of blocks and dies is carried on to a large extent. In the wheel shop there are two powerful nydraulic presses for pressing the wheels on and off the axles these are worked by pumps, which give a pressure on the ram of 20Q tons. The various processes of turning and slotting the wheels, tires, axles, and crank axles were seen in action, including six lathes with 9-feet face Pjates- We reserve a description of other portions of the works for our next issue.

pressure. This steamer, which is the third of similar type built by the Elsinore Iron Shipbuilding and Engineering Company for the some owners, viz. the Steamship Company Kobenhavn, of Copenhagen, was run over the measured mile, the result being a mean speed of 10 4 knots on a very moderate consumption of coal. Comet September Hugh M'Intyre, marine surveyor, of Glasgow, had a trip down the Firth in his new paddle-yacht, which has been built specially for the purpose of showing in a practical manner that paddlewheels or screw-propellers geared in the manner patented bjr Mr. M'Intyre will be much more effective and economical than direct acting engines.

It is claimed by the patentee that the machinery will be cheaper, 40 per cent to 50 per cent, lighter, and the consumption of coal about one-third that of the present compound or surface-condensing paddle-engines. The engines, which are by Messrs. Hanna, Donald Wilson, of Paisley, are triple- expansion horizontal cylinders, ana 14 inches, by 9-inch stroke. The'boiler is a return tubular one of the ordinary type, working at 170 lb. pressure, and can be worked by natural or forced draught, the fan being driven by the circulating-pump engine.

The patent consists in the engine being geared to the paddle-wheel instead of acting direct, ana in this way exercising more power. A speed of about 12 miles an hour was attained, but after some alterations have been made a much higher speed is expected. September 17, this screw-steamer, built by the Ailsa Shipbuilding Company, and engined by Messrs. Dunsmuir Jackson, of Govan, ran her official trial trip, when, on the measured mile, she attained a speed of knots per hour. She has been built for the Consorzis Vapore Dubrovnik, of Ragusa, is of the following Length, 170 feet; breadth, 25 feet; depth, moulded, 12 feet.

Engines, triple-expansion. Cylinders, 16, 26, and 40 inches by 30-inch stroke. Isis. September 24, this steamship, built by the Naval Constructions and Armaments Company, Limited, of Barrow, to the order of Messrs. Aitken Walker, of Glagffow, went on her trial trip.

The engines, which are triple-expansion, have been supplied by Messrs. Muir Houston, of Portman Street, Glasgow. The run over the measured mile was satisfactory, the speed being knots. Mud Turtle. September 20, this twin-screw hopper-dredger, constructed by Messrs.

William Simons of Renfrew, for the Indian Government, was tried on the Clyde with very satisfactory results. The machinery worked with great smoothness, and the work done proved that the dredging capabilities of the vessel were considerably in excess of that contracted for. The vessel is propelled by two sets of triple-expansion engines, and the mean speed obtained on four runs on the measured mile was fully one mile in excess of that guaranteed. On September 24, this screw-steamer left the No. 2 dockyard of Sir Raylton Dixon of Middlesbrough, for her official trial trip, which was in every way satisfactory, and at the completion the vessel left for Cardiff to load for Port Said.

This vessel has been built to the order of Mr. R. B. Chellew, of Truro, and is the eighth vessel belonging to this fleet. over all, 311 feet; breadth, 40 feet; depth, moulded, 22 feet inches; deadweight carrying-capacity, 4,000 tons.

Engines, triple-expansion, by Messrs. Thos. Richardson Sons, of Hartlepool. Cylinders, 23, 37i, and inches by 39 inches stroke. Magna.

September 24, this steamer, built by Messrs. Wood, Skinner of Bill Quay, for Mr. Harold Isaaksen, of Grimstad, Norway, left the Tyne for her trial trip. The vessel is of 2,700 tons capacity, and the triple-expansion engines, by the North-eastern Marine Engineering Company, Limited, of Wallsend, are of about 850 horse-power. Throughout the trial the engines worked in the smoothest possible manner.

Tchihatchoft. screw-steamer, built by Messrs. Denny Brothers, of Dumbarton, went down the Clyde on September 21 on her trial trip. The vessel has been constructed for the Russian Steam Navigation and Trading Company, of Odessa and St. Petersburg.

Her tonnage is 4,200 gross. Dimensions 360 feet; breadth, 45 feet; depth, 31 feet. Engines, triple- expansion, by Messrs. Denny of about 3,500 indicated horse-power. The measured mile was first run, and the vessel registered knots, the ean of six runs between Cloch and Cumbrae Lights.

THE second-class cruiser Brilliant started from the Nore on September 23 for an eight hours' trial of her machinery. The trial was attended with unsuccessful results, the boilers priming and the gudgeon bearings becoming overheated. The vessel returned to Sheerness in the evening to prepare for another trial. The anchor trials of the Brilliant also proved unsatisfactory. The engines were supplied by contract.

THE second-class ciuiser Iphigenia, having failed to pass her steam-trials (successfully by reason of leaking boilers, has been fitted with the Admiralty ferrules, and on September 23 she proceeded to Spithead to try her engines under the new conditions. The results under natural draught were highly satisfactory both with respect to power and speed. Tne Iphigenia completed her contractor steam-trials at Ports in somewhat wild forced draught. QUth on September 27, eather, by a four hours'run under The result was also satisfactory..
