The plan upon the adjoining page will give the reader some idea of the extent of the accommodations required for the manufacture of such heavy and massive machinery. On the right of the entrance may be seen the porter's lodge, shown in perspective in the view below. Beyond it, in the yard, stands the crane, which is seen likewise in the view. Turning to the left, just beyond the crane, the visitor enters the iron foundry, a spacious inclosure, with ovens and furnaces along the sides, and enormous cranes swinging in various directions in the centre. These cranes are for hoisting the heavy castings out of the pits in which they are formed. The parts marked v v v, are ovens for drying the moulds. [Illustration] Turning to the right from the foundry, and passing down through the yard, the visitor finds himself in the midst of a complicated maze of buildings, which extend in long ranges toward the water, with lanes and passages between them like the streets of a town. In these passages companies of workmen are seen, some going to and fro, drawing heavy masses of machinery upon iron trucks; others employed in hoisting some ponderous cylinder or shaft by a crane, or stacking pigs of iron in great heaps, to be ready for the furnaces which are roaring near as if eager to devour them. And all the time there issues from the open doors of the great boiler-shops and forging-shops below, an incessant clangor, produced by the blows of the sledges upon the rivets of the boilers, or of the trip-hammers at the forges. The relative positions of the various shops where the different operations are performed will be seen by examination of the plan. The motive power by which all the machinery of the establishment is driven, is furnished by a stationary engine in the very centre of the works, represented in the plan. It stands between two of the principal shops. On the right is seen the boiler, and on the left the engine--while the black square below, just within the great boiler-shop, represents the chimney. Other similar squares in different parts of the plan represent chimneys also, in the different parts of the establishment. These chimneys may be seen in perspective in the general view, at the head of this article, and may be identified with their several representations in the plan, by a careful comparison. The one belonging to the engine is the central one in the picture as well as in the plan--that is, the one from which the heaviest volume of smoke is issuing. This central engine, since it carries all the machinery of the works, by means of which every thing is formed and fashioned, is the life and soul of the establishment--the _mother_, in fact, of all the monsters which issue from it; and it is impossible to look upon her, as she toils on industriously in her daily duty, and think of her Titanic progeny, scattered now over every ocean on the globe, without a certain feeling of respect and even of admiration.
