PARIS AERO SHOW.
THIS interesting monoplane, illustrations of which appeared in FLIGHT for December 9th, 1911, constructed to the designs of M. Henri Chazal, is interesting for the fact that its wings are pivoted, by which system their angle of incidence may be varied at the will of the pilot while in flight, and on landing they may be folded back against the fuselage by the mere turning of the wheel on the right of the pilot. To effect this each wing is mounted on and braced to a mast, which is attached at an angle to the fuselage. The adjustment of the wings for balancing purposes is made from the pilot's control wheel. Supposing the machine to be dipping on the left-hand side, the control wheel will be rotated towards the right, which action advances the axis of the left wing, and retards the axis of the right wing a similar amount. It is by virtue of the oblique mounting of the masts that the advancing or retarding of the wings causes their angle of incidence to be increased or diminished respectively.
The convenience of this method of wing-mounting is amply demonstrated by the fact that the machine was towed through the streets of Paris from its hangar at Issy-les-Moulineaux to the Grand Palais without being dismantled; and its re-erection at the latter place merely consisted of about a dozen rotations of the wing operating-wheel. To further assist the ease with which the machine may be steered over the ground, the rudder is made to work in conjunction with a pair of pivoting wheels, situated under the tail. The landing-chassis is identical with that of the Zodiac biplane, except that no provision is made for the accommodation of any sideway's movement in landing. Its propulsive group consists of a Gnome engine and a Chauviere propeller. Accommodation is provided for a passenger, and to lend a little realism to the assertion of the Marcay-Moonen people that their machine has been designed purely for military work, this latter's cockpit was equipped with a quick-firing gun and a wireless telegraphy installation.

Testing the Marcay Moonen Monoplane.
ON the 27th ult. the Marcay Moonen monoplane, which has its wings pivotted so that they may be folded back, was tested at Issy and apparently gave very good results. It was piloted by Aerremans.
