A pistol ought to be invented which will fire eight or ten shots in
rapid succession, the discharge continuing simply by the holding back of
the trigger. In many kinds of fireworks the balls are sent off in
succession in this way, while the piece is held in the hand. Apply the
same or a similar principle to the pistol, and your reward will be that
of a Mauser or a Maxim.
