Handsome is as handsome does; these two sisters, one of which is no
more, were not long in showing that their achievements were not belied
by their good looks. In appearance less like “the biggest things
afloat” than the most symmetrical colossal yacht, the _Campania_ was
built for business, and not primarily to be a thing of beauty. She has
made the run between Queenstown and New York in 5½ days, and ocean
travellers soon appreciated the important fact that in getting from one
country to the other she had a reputation for regularity that would be
hard to beat, irrespective of winter and summer weather. The _Campania_
is slightly larger than her late sister, and has averaged just under
22 knots for a whole year’s east-bound voyages. The engines of these
elegant ships were arranged in the manner already indicated so as to
avoid having unnecessarily large cylinders, the two high-pressure
cylinders driving one crank, being arranged tandem fashion, the
intermediate cylinder driving one crank, whilst the two low-pressure
were also put the one above the other like the high-pressure, and by an
ingenious contrivance it is possible to prevent the screws racing; for
when the number of revolutions begins to exceed its proper limit the
supply of steam is automatically cut off.
In order to render these boats less likely to roll in a sea-way, they
were fitted with bilge-keels. They have, too, since been provided with
wireless telegraph gear, whose aerials stretch from one mast to the
other, and connect with the Marconi cabin, and the up-to-date system
of submarine signalling is also installed, so that in case of thick
weather the sound waves transmitted from submerged bells on lightships
outside Liverpool or New York may be conveyed to the ship herself below
the waterline, and so by means of a telephone up to the officer on duty
in the navigating room.
