From the smallest fitting up to the great engine cranks, the lathes smooth them all--reduce them to the precise size which they were intended to be by the draughtsman. These cranks and larger pieces of metal are conveyed to their lathes and placed in position by a steam crane, which glides along upon a single rail at the will of the driver, who rides on it, and which handles the massive metal almost with the same facility that an elephant would move a log of wood with his trunk. Most of us have an inherent idea that iron is exceedingly hard, but the ease with which it is cut and smoothed by these machines goes far to remove that impression. The carriage department does not offer so much that will strike the eye, yet it is of the highest importance. To the uninitiated it is difficult to trace the connection between the various stages of the carriage, as it is progressively built up, and finally painted and gilded and fitted with cushions. Generally, the impression left from an inspection is that the frames of the carriages are made in a way calculated to secure great strength, the material being solid oak. The brake-vans especially are made strong. The carriages made here are for the narrow gauge, and are immensely superior in every way to the old broad-gauge carriage, being much more roomy, although not so wide. Over the department there lingers an odour of wood. It is common to speak of the scented woods of the East and the South, but even our English woods are not devoid of pleasant odour under the carpenter's hands. Hidden away amongst the piles of wood there is here a triumph of human ingenuity. It is an endless saw which revolves around two wheels, much in the same way as a band revolves around two drums. The wheels are perhaps three feet in diameter, and two inches in thickness at the circumference. They are placed--one as low as the workman's feet, another rather above his head--six or seven feet apart. Round the wheels there stretches an endless narrow band of blue steel, just as a ribbon might. This band of steel is very thin, and almost half an inch in width. Its edge towards the workman is serrated with sharp deep teeth. The wheels revolve by steam rapidly, and carry with them the saw, so that, instead of the old up and down motion, the teeth are continually running one way. The band of steel is so extremely flexible that it sustains the state of perpetual curve. There are stories in ancient chronicles of the wonderful swords of famous warriors made of such good steel that the blade could be bent till the point touched the hilt, and even till the blade was tied in a knot. These stories do not seem like fables before this endless saw, which does not bend once or twice, but is incessantly curved, and incessantly in the act of curving. A more beautiful machine cannot be imagined. Its chief use is to cut out the designs for cornices, and similar ornamental work in thin wood; but it is sufficiently strong to cut through a two-inch plank
