Not an uninteresting department is the smithery. Its length is 306 feet and it is 48 feet wide. On entering one seems to have got into a region where Vulcan and his Cyclops are at work, not forging thunderbolts for Jupiter, but giving shape and form to bars of half-molten iron, which shall afterwards be used in the structure of steam-engines and for other practical purposes. The scene is grand, and might supply a study for such painters as West, Stothard, Conway and Northcote. In the back ground is a depth of gloom, sombrous and murky which is relieved at intervals by the fierce glare of thirty fires. At as many anvils strong, athletic, Titan-like figures, with uplifted arm and heavy stroke scatter "as from smitten steel," sparks like brilliant stars, in all directions. Here are thirty smiths' forges, and the tools used by the smiths, as tongs, hammers, swages, etc., are arranged in racks against the walls. Here also are two steam-hammers, one fifteen tons, the other five tons. Either can be most scrupulously adjusted by aid of a small lever. Here also are furnaces, a stationary engine with fan, grindstone, and powerful shears for cutting bar-iron. Lines of rails run throughout the shop, so that the coal and iron can be conveyed to any part where it is required. A Second Shop for Carriages, Waggons, etc., is being erected at an estimated cost of nearly £14,000. The carriage shop is 370 feet long, 150 feet wide, 30 feet high in the centre, and is capable of containing 80 railway carriages. It is divided longitudinally into three parts by the two rows of iron pillars which support the roof. The central division is forty feet wide and is occupied by the traversing table which is used for shifting the carriages. The two side divisions are the parts for vehicles under repairs, and are also occupied by the workmens' benches, etc. The roof is composed of a light but strong iron framing covered first with deal boards, and with slates over all except the central part, which is composed almost entirely of glass. The floor consists of wood bricks, laid on a solid foundation of concrete, and is intersected by the iron rails for the carriages and traverser. At the south end are the offices, with the trimming shops above them. The shop is well and efficiently ventilated, and is furnished with a system of heating apparatus consisting of a double row of large steam-pipes passing all round under the windows. Water is laid on in ample quantities, and one of the regulations carried out with unvarying rule, is to fix hose pipes in two separate parts of the shops every night with stand pipes ready for instant use in case of fire. There are 130 windows in the shop exclusive of the roof. Most of the carriages are made of teak instead of mahogany, as being more durable as well as economical and not so likely to split when exposed to the heat of the sun.
