Top speed,240km./hr, ; stalling speed, 90 km./hr. Climb to 5,000 m. in 20 mins. Ceiling, 7,000 m. MORANE SAULNIER. THIS veteran firm of aircraft builders, which originated theparasol monoplane type—a type that enjoys today great popularity among French constructors, as will be seen fromthe exhibits of the Salon—will exhibit three machines. The first of these is the Morane-Saulnier type 35 E.P.2elementary training aeroplane, with 80 h.p. Le Rhone engine (the letters E.P. stand for ecole primaire) ; the second is atype 129 E.T.2 (180 h.p. Hispano-Suiza) advanced training aeroplane (the letters E.T. meaning ecole de transition) ;the third machine is the type 132, with 120 h.p. Salmson air- cooled engine, which is mainly intended for touring pur-poses, but may also be used for training work. the seats are adjustable in height and the rudder bar may beadjusted for distance from the seat. Constructionally the 129 E.T.2 follows the practice ofthe 35 E.P.2, that is, the machine is timber-built throughout except for the wing spars which are duraluminium tubes, andthe undercarriage struts which are steel tubes. The engine unit, which is mounted on duralumin tubes, is detachable byundoing a few bolts. The vast experience which the Morane-Saulnier firm hasaccumulated in the long years its training school has been in existence at Villacoublay may be said to have taken bodyin the type 129 E.T.2, a machine so proportioned as to let the pupil do all the mistakes he can so he may realize theirgravity, but with a sufficient tendency to inherent stability so the machine will " forgive the mistake." THE MORANE-SAULNIER 129 E.T.2, with 180 His-pano, is an advance training aeroplane. Morane-Saulnier Type 132 Touring Aeroplane.This machine is essentially an adaptation of the above described advanced training aeroplane to the requirementsof grand tourisme, or distant touring. Both machines are constructionally identical, and have the same wing area(19-7 sq. m.), but the touring type is equipped with a 120 h.p. Salmson air-cooled radial engine instead of with a 180 h.p.Hispano-Suiza. THE MORANE-SAULNIER E.P.2, with 80 h.p. le Rhone, is an elementary training machine. The 3i> E.P.2 elementary training machine, of which largenumbers exist in the French and foreign military air services, is too well known to require more than a brief mention. Theframing of the wings is of timber, except for the spars, which are duralumin tubes. The fuselage has wooden longeronsand plywood formers. Both the wings and the fuselage are fabric-covered. The undercarriage struts are steel tubes. Special care has been taken to make the controls highlyresponsive and so enable the instructor to impart to his pupil good flying manners ; with this end in view the pivotedportions of the controls are mounted on ball bearings, thus insuring great smoothness of action. The tail skid is steer-able. The normal equipment includes a fire extinguisher andparachutes for the two occupants. Morane-Saulnier Type 129 E.T.2 Aeroplane The Morane-Saulnier type 129 E.T.2 advanced trainingaeroplane is a strut-braced' parasol monoplane which incox- porates a particularly complete system of safety features,among which may be mentioned a droppable petrol tank, fire extinguishers, back or seat type parachutes and a self-starter. Special attention has been paid, furthermore, to making the pupil feel comfortable on board ; for the purpose THE MORANE-SAULNIER 132, with 120 h.p. Salmson, is designed as a touring machine. The type 132 incorporates all the safety features and prac- tical points which have been noted above in connection with the advanced training type of aeroplane.

ATELIERS DES MUREAUX THE Ateliers des Mureaux, of Les Mureaux (Seine-et-Oise), will have at its stand in the Salon a Mureaux " Express Marin " single-seater fighter with 420 h.p. Gnome-Rhone engine, and one of the military aeroplanes the company is building under sub-contract for the French Military Air Service, probably a Breguet 19.A.2. The Mureaux " Express Marin " is a tractor parasol monoplane of the strut-braced type, which is fitted with a watertight stepped hull for alighting on the sea. To facilitate this manoeuvre the nose of the fuselage is flared out into wing-root like excrescences (there being no wing-tip floats), which contribute to the buoyancy and hydrodynamic stability of the machine. Besides, the undercarriage can be dropped by the pilot. 784
