FEBRUARY IO, 1912. I/Hl this machine has shown. The trailing edge is of flexible construction so that any temporary increase of pressure beneath one wing may be automatically released. Hickory is employed for the spars, and the libs are of I section, constructed from pine and ash. These same materials are used to form the framework of the stabilizing surface at he rear, and in both cases three-ply wood is made use of to form the leading edge. The fabric covering of the wings is treated, as is customary in the Deperdussin workshops, by several successive coatings of special varnish which renders it impervious to water, oil and petrol. Stranded steel cables are provided to take the weight of the machine in flight. Despite the amount of criticism that was applied to the Deper- dussin-type of landing gear at the time of its first appearance at the Paris Aero Show over a year ago, and has been applied at occasional intervals since then, this section of the machine has not, even in this latest model, where landing is effected at speeds in the neighbourhood of 90 miles an hour, undergone the slightest change. This, in our opinion, is sufficient evidence of the soundness of its design. Quite novel is the fitting of the rear skid. Only that part which rubs on the ground emerges from the fuselage, the remainder, together with the elastic cord attachment which endows this organ with flexibility, is disposed in its interior, a feature making for lessened head The Prince Henry Cup. THE cup which Prince Henry of Prussia has offered in con nection with the Upper Rhine cross-country competition from May I2th-25th, will only be open to military aviators, and amateurs and manufacturer's pilots are ineligible. Each competitor must be followed in his flight by a motor car carrying an official observer and the necessary tools and spare parts. In the case of repairs only one mechanic may assist the pilot. The organisers will indemnify the makers of the competing machines at the rate of 1,000 marks per machine per stage. The flights will be followed by three dirigibles carrying official observers. resistance and cleanness of design. The tail has been particularly low built in relation to the front part of the machine, in order that it may leave the ground more quickly, and pull up in a shorter time on landing. As regards the tail, the arrangement of this organ is essentially the same as on the firm's less speedy machines, excepting that the surfaces are applied without the use of bracing wires or strainers. The controlling arrangements are absolutely identical with those on the standard types of this firm's productions—a wheel mounted vertically at the centre of an inverted U-shaped sweep of wood being pulled towards and pushed away from the pilot to effect elevation and depression, while rotating it laterally actuates the warping. One difference is evident, however, that the control is, in this machine, totally enclosed in the fuselage. The rudder is operated from a pivoted foot-bar. Tractive force is derived from a 14-cylinder 100-h.p. Gnome engine direct coupled to a rapid propeller of 8 ft. 3 ins. in diameter. The main support of the engine is at the rear, but there is also a subsidiary support in front composed of three steel tubes arranged Y fashion. A thin shield of aluminium covering the motor effec tively prevents any oil from being thrown in the direction of the pilot. ® ® ® ® The Austrian Aeronautical Exhibition. THE International Flight Exhibition al Vienna, which is being organised by the Austrian Technical Flying Society, assisted by the Austrian Government, under the patronage of the Emperor of Austria, promises to be very successful. It will be held during the four weeks from May 18th to June 23rd, and exhibits will be divided into seven classes, embracing an historical section and sections for free balloons and airships, gliders and aeroplanes (including kites), aero-motors, special apparatus (including machine tools, &c.) and models. Full particulars can be obtained from Vienna .1, Aspernpl atz, Urania- gebaude.
