Another essential feature of the type is the system by which the valves
are worked automatically. At the present time there is no other system
of valve working so reliable as this.

A third essential feature of the class is the use of a swinging car, in
such a manner that pitching, due to alterations of propeller thrust, is
automatically checked by an alteration of the position of the centre of
gravity.

A fourth feature is the use of limp propeller blades. A propeller of
this type is very easily packed up.

The shape of these vessels is in accordance with the experiments of
Professor Prandtl.
