IRONCLADS.

A modern ironclad is an enormous piece of complicated mechanism. In order to protect this mechanism from hostile shot, the greater part of it is placed under water and covered by a thick steel deck; the remainder above water being protected by vast armour-plates varying from eight to twenty-four inches in thickness. From the exterior, an ironclad is by no means a thing of beauty; one writer has described it as 'a cross between a cooking apparatus and a railway station;' but in place of this ingenious parallel, imagine a low flat-looking mass on the water; from the centre rises a huge funnel, on either side of which are a turret and a superstructure running to the bow and stern; two short pole masts, with platforms on the top for machine guns, complete an object calculated to bring tears to the eyes of the veteran sailor who remembers the days of the grand old line-of-battle ship, with its tall tapering masts and white sails glistening in the sun. A stranger going on board one of our newest types of ironclads would lose himself amid the intricacies and apparent confusion of the numerous engines, passages, and compartments; it is a long time, in fact, before even the sailors find their way about these new ships; and the Admiralty allow a new ironclad to remain three months in harbour on first commissioning before going to sea, in order that the men may become acquainted with the uses of the several fittings on board, each ironclad that is built now being in many ways an improvement on its predecessor.

Those who have not been on board a modern ironclad can form no idea of the massiveness and solidity of the various fittings; the enormous guns, the rows of shot and shell, the huge bolts, bars, and beams seem to be meant for the use of giants, not men. Although crowded together in a comparatively small space, everything is in perfect order, and ready at any moment to be used for offensive or defensive purposes. It is not, perhaps, generally known that the captain of a man-of-war is ordered to keep his ship properly prepared for battle as well in time of peace as of war. Every evening before dark the quarters are cleared and every arrangement made for night-battle, to prevent surprise by a better prepared enemy. When at anchor in a harbour, especially at night, the ship is always prepared to repel any attempts of an enemy to board or attack with torpedoes or fireships. In addition to the daily and weekly drills and exercises, once every three months the crew are exercised at night-quarters, the time of course being kept secret by the captain, so that no preparations can be made beforehand, the exercise being intended to represent a surprise. In the dead of night, when only the officers of the watch and the sentries posted in the various parts of the ship are awake, the notes of a bugle vibrate between the decks; immediately, as if by magic, everything becomes alive; men are seen scrambling out of their hammocks, and lights flash in all directions; the huge shells are lifted by hydraulic power from the magazines, placed on trucks, and wheeled by means of railways to the turrets; men run here and there with rifles, boarding-pikes, axes, cases of powder and ammunition; others are engaged laying fire-hose along the decks, others closing the water-tight doors; while far down below, the engineers, stokers, and firemen are busy getting up steam for working the electric-light engines, turrets, &c. At the torpedo ports, the trained torpedo-men are placing the Whiteheads in their tubes; others are preparing cases of gun-cotton for boom-torpedoes. In ten minutes, however, all is again silent and each man stands at his station ready for action. The captain, followed by his principal officers, now walks round the quarters and inspects all the arrangements for battle, after which various exercises are gone through. A bugle sounds, and numbers of men rush away to certain parts of the ship to repel imaginary boarders; another bugle, and a large party immediately commence to work the pumps; another low, long blast is a warning that the ship is about to ram an enemy, and every man on board stretches himself flat on the decks until the shock of the (supposed) collision takes place. After a number of exercises have been gone through, the guns are secured, arms and stores returned to their places, the men tumble into their hammocks again, and are soon fast asleep.

It would be interesting to glance at some of the principal offensive and defensive capabilities of a modern ironclad. The first-class line-of-battle ship of fifty years ago carried as many as a hundred and thirty, what would be called in the present day, very light guns; in contrast to this, her Majesty's armour-plated barbette ram Benbow carries two guns weighing a hundred and ten tons each. These enormous weapons are forty-three feet eight inches long, and are capable of sending a shot weighing three quarters of a ton to a distance of seven miles. The effect of a shell from one of these guns piercing the armour of a ship and bursting would be very disastrous, and there are few, if any, ships whose armour, when fairly hit at a moderate distance, could withstand such a blow.

Guns, however, although terrible in effect, are now supplemented by other and more deadly means of offence. Foremost amongst these stands the Whitehead or Fish Torpedo. This infernal machine can be discharged from tubes in the side of a ship to a distance of a thousand yards under water at a speed of twenty-five miles per hour. Armed with its charge of gun-cotton it rushes forth on its mission; and, if successful in striking the ship against which it is aimed, explodes, and rends a large hole in her side, through which the water pours in huge quantities. In order to protect a man-of-war from this danger, she can be surrounded at short notice with thick wire-nettings, hanging from projecting side-spars, against which the torpedo explodes with harmless effect. These nettings are, however, principally intended for use when ships are at anchor in harbour at night; they could not well be employed in action with an enemy, as they offer such resistance to the water as to reduce the speed of the ship by four or five knots, and so encumber her as to render her liable to be rammed by a more active opponent.

All large ironclads now have two or three torpedo boats. These craft are constructed of steel one-sixteenth of an inch thick, and steam at a speed of sixteen knots, some of the larger kind reaching twenty or twenty-one knots an hour. Carrying two Whiteheads, they are valuable auxiliaries to the parent ship; their rapid movements, together with their dangerous freight, distracting the attention of an enemy.
