In 1905, the German Hamburg-American Line became possessed of the
_Amerika_, which with the length of 670½ feet, beam 74·6, and a tonnage
of 22,225, and a moderate speed, makes her rather a rival of the
White Star _Baltic_ and _Adriatic_, than of the Cunard ships or the
Norddeutscher Lloyd _Kaiser Wilhelm der Grosse_ and _Kaiser Wilhelm
II._, and the Hamburg Company’s own fast steamship, the _Deutschland_.
Although sailing under a foreign flag, she is to all intents and
purposes a British ship, for she was built at Harland and Wolff’s
famous Belfast yard, where the White Star ships have come into being.
Her speed is 18 knots, so that she is rather faster than the latest
White Star ships, although inferior to the fastest contemporary liners.
Carrying a total of 4,000 passengers and crew, the _Amerika_ is one of
the finest vessels, not merely in the German fleet, but in the whole
world.

The _George Washington_, which is seen steaming ahead in the
illustration herewith, was the first of the Norddeutscher Lloyd
steamers to make a considerable advance on the 20,000 tons (registered)
limit. In length, breadth and tonnage she was launched as the biggest
of all German ships, and some of her details are not without interest.
Her speed of 18½ knots is obtained by two engines with an indicated
horse-power of 20,000, and her gross register is 26,000 tons. She
is propelled by twin-screws, and was built of steel according to
the highest German standards, with five steel decks extending from
end to end, a double bottom, which is divided up into twenty-six
water-tight compartments, while the ship herself is divided by
thirteen transverse bulkheads which reach up to the upper deck, and
sometimes to the upper saloon deck, and separate the vessel into
fourteen water-tight compartments. A special feature was made in the
bulkheads to render them of such a strength as to be able to resist
the pressure of the water in the event of collision. The three upper
decks seen in the photograph show the awning, the upper promenade,
and the promenade-decks; while, as in the _Mauretania_ and her
sister, and in the _Adriatic_, electric lifts are installed for the
convenience of the passengers wishing to pass from one deck to the
other. The four pole-masts are of steel, and have between them no fewer
than twenty-nine derricks. The _George Washington’s_ engines are of
the quadruple-expansion type, with two sets of four cylinders, the
propellers being two three-bladed, made of bronze. The difficulty
with large reciprocating engines has always been to cause them to
work without giving forth considerable vibration. But the careful
arrangement of the cranks of the engine so as to balance each other
tends to neutralise the vibration.
