operates the elevator, while a sideways motion controls the warp. The lever itself is attached to a rock shaft that runs a little way down the body until it comes vertically over the pillar supporting the warp wires. are used in the first three bays, pine being employed for the struts further aft. The wings have no dihedral angle, as the designers object to this feature. The wing spars are of ash, and " Flight " Copyright. Lower pylon and its fittings, and on the right, sketch showing method of anchoring lift cables to the chassis members. The rudder is controlled as usual by foot. The rudder and warp wires are enclosed in the body of the machine except for a very short length near the extremity, where they are attached to their respective organs. A peculiarity of the tail is the absence of a fixed horizontal plane, the movable elevator being the only horizontal member. This elevator belongs to what is known as the balanced type, that is to say, its axis of rotation is situated more or less in the position of the usual centre of pressure, so that there is never a very great couple reacting upon the pilot's hand. The rudder is balanced in the same way. The machine is driven by an overhung 8o-h.p. Gnome engine, which is fitted with an 8 ft. Integrale propeller. Two tanks are arranged in the nose of the machine, one containing 14 gallons of petrol, and the other about 5 gallons of oil. A subsidiary petrol tank holding 8 gallons of spirit is located behind the passenger's seat, and there is a hand pump attached to it in a convenient position for transferring its contents to the service tank while in flight. A Bosch magneto firing Oleo plugs forms the ignition equipment of the engine, while a Tell revolution indicator, a barograph, a compass, and a map-holder are fittings in front of the pilot on the dashboard. The body of the machine is surfaced with fabric, but its interior structure is of the usual girder type. Ash booms are employed, and ash struts and cross-members ® ® Deperdusslns Flying in Notts. ON Thursday, Friday and Saturday of last week some splendid flying on Deperdussin monoplanes was seen at the Rolleston racecourse, the exhibitions having been arranged by Mr. J. Mather, of Newark. On the afternoon of the first day there was a forty mile wind blowing, but in spite of that Mr. W. Brock on the 35-h.p. Anzani-Oeperdussin made a good flight at a height of 2,000 ft. in the direction of Newark. Later in the evening he was up again, and this time went to Southwell, and on returning carried out several manoeuvres above the aerodrome before coming down. On this occasion he was in the air for over an hour. It had been hoped that during the afternoon Lieut. Porte would arrive on his big aeroplane from London, but the weather conditions were against it, and the journey had to lie made by road. As on the previous day a large crowd of people, many of them coming by motor cars, arrived At the race-course, but it was not until mid-day that the first flight was made. Then Mr. Brock went up and after making a few circuits the leading and trailing edges are fitted with pine stretchers. An internal bracing of piano wire is pro vided to stay the wing against drift. Both front and rear spars are hinged to the body, the Detail of top pylon. " Flight " Copyright. The forward bracing wires are carried round a pulley. former by a vertical bolt, and the latter, as usual, by a horizontal bolt to facilitate warping. With the exception of the internal wires, stranded cable is employed through out for the wing bracing and control. ® ® went off in the direction of Nottingham. In half an hour he was back again and made a fine landing. In two subsequent trips he climbed to a great height, and meanwhile Lieut. Porte made a number of short passenger flights. On Saturday there was a larger attendance than ever, and both Mr. Brock and Lieut. Porte made many short flights, the latter taking up a large number of passengers. It is proposed to have another meeting on August Bank Holiday, when it is hoped that some competitions may be arranged. The Wight Hydro-aeroplane. FORTUNATELY the accident to the hydro-aeroplane built by Messrs. J. Samuel White & Co. was not so serious as at first appeared, and we learn from Mr. T. Howard Wright that it is expected that the machine will be ready for trials again in about three weeks' time. The accident was caused through an error of judgment in putting the machine to climb too steeply. She behaved splendidly on the water, being very stable on the two floats, and getting off very quickly. 564
