“The above table shows at a glance the ships that have come between
the _Campania_ and the _Lusitania_. The _Baltic_ shows the type of
steamer that pays the best, going across at a moderate speed sufficient
for most people while at the same time carrying an enormous amount of
cargo.”[92]
[92] _Shipping World_, January 2, 1907.
Alterations have been made in the propellers of both these steamers
with a view to finding the size, pitch, number of blades, material,
weight, and number of revolutions per minute and the other details upon
which efficiency depends, but the result is carefully guarded. Such
tests are expensive.
In 1889 the White Star Company built the _Teutonic_ of 10,000 tons,
which, like her sister ship the _Majestic_, was intended to be an armed
mercantile cruiser. These two vessels, which each took nearly three
years in building, were at that time the finest the world had seen, and
the speediest, and were regarded with such wonder that at the naval
review in 1889, one of them was visited by the German Emperor and the
late King Edward (then Prince of Wales) and many distinguished officers
of the Navy. The _Majestic_ soon brought the record from Queenstown to
New York down to 5 days 18 hours 18 minutes, but this was reduced by
the _Teutonic_ to 5 days 16¹⁄₂ hours.
The second _Oceanic_, also of steel and a twin-screw boat, was placed
in the Liverpool and New York service in 1899. She was 704 feet in
length and was the first vessel to be built longer than the _Great
Eastern_, but in other respects she was smaller, her beam being 68·3
feet, her gross tonnage 16,900 and her displacement tonnage 26,100. The
indicated horse-power of the _Oceanic_ was 29,000 as against the 11,000
of the _Great Eastern_, and her speed was 21¹⁄₂ knots as compared with
13. In equipment, too, she was regarded as the last possible word in
luxury and magnificence. Her promenade deck was 400 feet long, and the
saloon was 80 by 64 feet, the latter surmounted by a glass dome 21 feet
square.
