From this partial list an idea may be formed of the extent and variety of the supplies that go to a modern war-ship. The clothing, medical and mechanical departments of the _Osprey's_ outfit are not included, and each in itself would make a long roll. Of course the delicacies mentioned above are for the officers' use alone. When in port or on a short cruise the sailors get fresh meat, bread, fruit, vegetables and milk. On a long voyage their staple is "salt horse, hard tack, and boot-leg," which, being translated, is corned beef or pork, with crackers and black coffee. They receive frequently, too, oatmeal and rice, hot rolls and tea. It will be noted that the important items of ice and fresh water do not appear in the list of supplies. Neither is taken aboard from the outside. The ship condenses fresh water pumped in from the sea by ingenious machinery contrived for the purpose, and the supply is limitless. From this fresh water ice is manufactured in any quantity desired, and no properly appointed modern war-ship is now without its ice-plant. It is for the manufacture of ice that ammonia is so largely shipped. In the general disposition of the stores and supplies the articles likely to be needed for immediate use are usually stored forward under the berth deck. Such stores as cloth and made-up wearing apparel go in the lower hold, and there are also nearly all the magazines, guncotton, and torpedo-heads, if the ship carries them. The coal bunkers on the _Osprey_ were located between the engines and boilers and the hull of the vessel, at a point a little abaft of midship. Thus the coal afforded protection to the machinery from projectiles aimed at the most vital part of the ship. Such inflammable liquids as oil and alcohol are never stowed below. Allusion has been made to the "life centre" of the vessel. This has been well described as the throbbing heart of every war-ship in the navy; the wires radiating from it like veins and arteries through which flow the life and intelligence which direct the movements of ship and crew. Innumerable electric lamps light the cabins, engine-rooms, magazines, conning towers and decks, while a finger's pressure on a knob, or the turn of a tiny handle, throws a flood of radiance streaming out into the black night, disclosing the enemy and rendering futile his attack or escape as the case may be. Other wires operate telegraph, telephone, and signal from the bridge, or move compartment doors, massive guns, and, on a battle-ship the huge turrets themselves.
