Consequently, the car may oscillate without altering its weight
position under center of supporting plane, thus avoiding an
involuntary alteration of speed or direction of flight.
That to steer a machine so constructed, it is merely necessary to move
the point of attachment of car to _machine_ proper, out of the center
of plane of support in the desired direction, and thus cause the plane
of support or rotation of propellers to incline in that direction.
That the reservoir of power, the boiler, etc., should be placed in the
_car_, and steam carried to engines through joint connecting car with
machine.
That at present material exists, and power also, of sufficient
lightness and strength to admit of a machine construction capable of a
limited successful flight in any fair wind and direction.
That such _machine_ once built, the finding of a _power_ for long
flights will be easy, if not already close at hand in _electricity_.
That the _easiest_ design for such _actual machine_ should be adopted,
leaving the adaptation of the principles involved to the making of
more perfect machines, to a time after the success of the _first_.
