communicating respectively with the turret, the engine-room, and steering-wheel. It is probable that the pilot tower would never really be made much use of, but that the Captain would fight his ship in the turret, from which he steers by sounding tubes. So much for the exterior of the Glatton-that is, from a general and very rough bird's-eye point of view. Horizontally the interior is divided into three flats, except in the regions of the boiler and engine the first consisting of the officers' and men's quarters; the second of store and ammunition rooms; with here and there empty spaces; and last and lowest of all comes the double bottom. Vertically the interior is divided into nine compartments, of which any one can be at a moment's notice isolated completely from all the rest, and have water, for instance, furiously pumped into or out of it by a system of piping, while the adjoining compartment is perfectly dry. This principle of isolation, intended obviously to prevent partial injury from becoming general, is one of the cardinal characteristics of the ship's construction, and is carried so far that not only each of the nine compartments, but even the subdivisions of these compartments, can be turned each into a little self-sufficing world of its own, to be destroyed by fire or water without involving other worlds in its destruction. In fact, almost every space in which a human being can turn round is an air-tight box fitted up with the most ingenious contrivances, not merely for isolating it, but for doing so from above-if necessary, without approaching it—and when you have done it informing you by tell-tale indicators that it is done. There are actually somewhere about 250 appliances, for keeping up this intercommunication in the shape of water-tight doors, hatches, valves, pipes, and tubes. There is an admirable. system of ventilation. The air is forced by steam-worked fans into a labyrinth of pipes, permeating the vessel as arteries the human body, and by simply turning a cock in any one of these pipes air is let into each room or safe as easily as water.
