Now, suppose that the head t the vessel rises two or three degrees, then the pen-dulum immediately falls against the after bar 15, raises thepinion lb, and thereby drives the rack 7 from left to operation lowers the tiller I. anil with it the steeringplanes on shaft 3. TI10 effect of this will be to slightly raisethe stern and to restore the vessel to 1 In- horizontal position. In order to slow up the vessel gradually and to comegently down to earth, one has only to push the pendulum for-ward by hand, when the rack 7 will be driven from right toleft by the pinion 10 ; the tiller and steering plants will thenbe inclined upward, thus bringing the stern downward. Theincreased angle of inclination at once reduces the speed of thevessel, and it approaches the ground slowly so as to In case of an accidental stoppage of the rotating shaft 8,the pendulum may he fixed and the rack 7 operated by handthrough a lever attached to one of the guide bars 20, or theshaft 8 may be turned by manual power. It is evident that the mechanical details may be varied toa very great extent. Mr. Moy estimates that for a one-man soaring apparatusthe whole of the automatic stability device would not exceed6 lbs. in weight. There are a good many working parts, butthey are all light, and the design is not as complicated as mayupon first sight appear. The proposal to apply an invertedinstead of a hanging pendulum seems to possess merit ; andit is to be hoped lhat some practical experiment upon anadequate scale will be made to test the value of the device inconferring automatic equilibrium upon a flying apparatus.
