These private promenades were expensive luxuries. The cost figured out something like forty dollars a front foot for a six days’ voyage. They, with the suites to which they are attached, were the most expensive transatlantic accommodations yet offered.
The engine room was divided into two sections, one given to the reciprocating engines and the other to the turbines. There were two sets of the reciprocating kind, one working each of the wing propellers through a four-cylinder triple expansion, direct acting inverted engine. Each set could generate 15,000 indicated horse-power at seventy-five revolutions a minute. The Parsons type turbine takes steam from the reciprocating engines, and by developing a horse-power of 16,000 at 165 revolutions a minute works the third of the ship’s propellers, the one directly under the rudder. Of the four funnels of the vessel three were connected with the engine room, and the fourth or after funnel for ventilating the ship including the gallery.
Practically all of the space on the Titanic below the upper deck was occupied by steam-generating plant, coal bunkers and propelling machinery. Eight of the fifteen water-tight compartments contained the mechanical part of the vessel. There were, for instance, twenty-four double end and five single end boilers, each 16 feet 9 inches in diameter, the larger 20 feet long and the smaller 11 feet 9 inches long. The larger boilers had six fires under each of them and the smaller three furnaces. Coal was stored in bunker space along the side of the ship between the lower and middle decks, and was first shipped from there into bunkers running all the way across the vessel in the lowest part. From there the stokers handed it into the furnaces.
One of the most interesting features of the vessel was the refrigerating plant, which comprised a huge ice-making and refrigerating machine and a number of provision rooms on the after part of the lower and orlop decks. There were separate cold rooms for beef, mutton, poultry, game, fish, vegetables, fruit, butter, bacon, cheese, flowers, mineral water, wine, spirits and champagne, all maintained at different temperatures most suitable to each. Perishable freight had a compartment of its own, also chilled by the plant.
Two main ideas were carried out in the Titanic. One was comfort and the other stability. The vessel was planned to be an ocean ferry. She was to have only a speed of twenty-one knots, far below that of some other modern vessels, but she was planned to make that speed, blow high or blow low, so that if she left one side of the ocean at a given time she could be relied on to reach the other side at almost a certain minute of a certain hour.
One who has looked into modern methods for safeguarding a vessel of the Titanic type can hardly imagine an accident that could cause her to founder. No collision such as has been the fate of any ship in recent years, it has been thought up to this time, could send her down, nor could running against an iceberg do it unless such an accident were coupled with the remotely possible blowing out of a boiler. She would sink at once, probably, if she were to run over a submerged rock or derelict in such manner that both her keel plates and her double bottom were torn away for more than half her length; but such a catastrophe was so remotely possible that it did not even enter the field of conjecture.

The reason for all this is found in the modern arrangement of water-tight steel compartments into which all ships now are divided and of which the Titanic had fifteen so disposed that half of them, including the largest, could be flooded without impairing the safety of the vessel. Probably it was the working of these bulkheads and the water-tight doors between them as they are supposed to work that saved the Titanic from foundering when she struck the iceberg.
These bulkheads were of heavy sheet steel and started at the very bottom of the ship and extended right up to the top side. The openings in the bulkheads were just about the size of the ordinary doorway, but the doors did not swing as in a house, but fitted into water-tight grooves above the opening. They could be released instantly in several ways, and once closed formed a barrier to the water as solid as the bulkhead itself.
In the Titanic, as in other great modern ships, these doors were held in place above the openings by friction clutches. On the bridge was a switch which connected with an electric magnet at the side of the bulkhead opening. The turning of this switch caused the magnet to draw down a heavy weight, which instantly released the friction clutch, and allowed the door to fall or slide down over the opening in a second. If, however, through accident the bridge switch was rendered useless the doors would close automatically in a few seconds. This was arranged by means of large metal floats at the side of the doorways, which rested just above the level of the double bottom, and as the water entered the compartments these floats would rise to it and directly release the clutch holding the door open. These clutches could also be released by hand.
It was said of the Titanic that liner compartments could be flooded as far back or as far forward as the engine room and she would float, though she might take on a heavy list, or settle considerably at one end. To provide against just such an accident as she is said to have encountered she had set back a good distance from the bows an extra heavy cross partition known as the collision bulkhead, which would prevent water getting in amidships, even though a good part of her bow should be torn away. What a ship can stand and still float was shown a few years ago when the Suevic of the White Star Line went on the rocks on the British coast. The wreckers could not move the forward part of her, so they separated her into two sections by the use of dynamite, and after putting in a temporary bulkhead floated off the after half of the ship, put it in dry dock and built a new forward part for her. More recently the battleship Maine, or what was left of her, was floated out to sea, and kept on top of the water by her water-tight compartments only.
CHAPTER III. THE MAIDEN VOYAGE OF THE TITANIC
EVER was ill-starred voyage more auspiciously begun than when the Titanic, newly crowned empress of the seas, steamed majestically out of the port of Southampton at noon on Wednesday, April 10th, bound for New York.
Elaborate preparations had been made for the maiden voyage. Crowds of eager watchers gathered to witness the departure, all the more interested because of the notable people who were to travel aboard her. Friends and relatives of many of the passengers were at the dock to bid Godspeed to their departing loved ones. The passengers themselves were unusually gay and happy.
Majestic and beautiful the ship rested on the water, marvel of shipbuilding, worthy of any sea. As this new queen of the ocean moved slowly from her dock, no one questioned her construction: she was fitted with an elaborate system of water-tight compartments, calculated to make her unsinkable; she had been pronounced the safest as well as the most sumptuous Atlantic liner afloat.
