two bedrooms and a bath.

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

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
