trie controls by which the 73,0OO-

There will be scarcely a flutter
Of annoyance when one of the

nfher ships. SO low has 1T been
nitcbed that it will not distress the
most sensitive human ear, but SO

By these contrasts in delicacy

Dual control systems, operated

There are two Starboard engine

EVEN THE WIND is FOOLED
Out on the bridge, in front of
the wheelhouSe. officers on watch
will be screened against storm by
an ingenious arrangement which
forces onrushing wind to rise be-
fore and over them, and form q
protective shield.
They will stand in comparative
calm. while the wall of high
pressure air, formed through a
Slot running along the bridge, will

enclosed wings reach IL feet be-
