The scene within the high brick walls which keep out idlers is exhilarating but scarcely picturesque. All the materials which enter into the construction of a modern ship are visible in profusion. A bird’s-eye view reveals great stacks of timber, iron, and steel; a net-work of rails which connect the works with all the principal lines converging at Glasgow; long brick sheds, and edging the water-front the launching-slips, where as many as fifteen vessels have been in course of construction at the same time. There the great hulls of many of the most famous Atlantic liners have been put together; this was the birthplace of all the new ships of the North German Lloyd line; of the Arizona, the Alaska, the Oregon, the Umbria, and the Etruria. Running at right angles from the river, a dock has been excavated, large enough to accommodate a vessel of twelve thousand tons, and after launching, the steamers are hauled in here to receive their engines and boilers. Immediately in the rear of the launching-slips there is an enormous shed, with a roof of glass and iron, where all the iron-work for the hulls of fifteen ships has been handled at one time. Within it gangs of workmen, each skilled in a specialty, carry on that part of the work which belongs to them. Some are carriers of angle steel or iron, others receivers of angle iron, which they place in the furnaces until the metal is at such a heat that it can be shaped to suit the water-lines of the vessel for which it is intended. Others still are busy with reverse frames and with the bending of plates; others with funnels, ventilators, and skylights. [Illustration: The Manganese Bronze Propeller-Blade of the Wrecked Steamer Mosel, after it had beaten upon a reef.] There is a special department for the casting of manganese bronze, which is used for the blades of propellers. Standing against a wall not far off is a blade saved from the propeller of the wrecked steamer Mosel. She ran ashore on a rocky coast, and her propeller played upon the reef like a flail upon a threshing-floor without break or fracture; so great is the strength of the bronze that the only effect upon it was a feathering of the edges as revealed by the blade in question.
