DECEMBER 11, 1924 the two cuts are so arranged as to give the required angle of incidence at any point along the radius. It will be seen that near the boss the section of each blade is semi-circular, while everywhere the section is an arc of a circle, except for such small changes as are made while grinding down the thickness, when, presumably, it is possible to change the outer sections into something approaching a proper aerofoil shape. The roots of the two blades have shoulders left on their forward face so as to take centrifugal stresses, and the two halves of the propeller are locked by the propeller boss and by a plate on the front, as shown by our sketches. By undoing the nuts it is possible to rotate the blades and set them to any angle required, and then locking them in place. In addition to the machines referred to, one of the N.l D-29 Cl's is exhibited, and also a small cabin machine belonging to the Compagnie Aerienne Francaise. SOCIETE INDUSTRIELLE DES METAUX ET DU BOIS (" Ferbois ") GENERALLY known by the initial letters S.I.M.B. of its title, this firm has absorbed the old Adolphe Bernard company, its chief designer being M. J. Hubert, whose " Ferbois " all-metal monoplane was exhibited at the 1922 aero show. The machine shown this year, although somewhat similar in appearance, is of entirely different construction, being constructed mainly of wood. Thus,«the fuselage is a wooden monocoque, and the wings also are covered with three-ply. The all-metal machine is, we understand, to be developed as a single-seater fighter, while the machine exhibited is the actual one used bv Adjutant Chef Bonnet at Istres, when he estab- LIGHT 'PLANE PROGRESS is slowly but surely being made in the formation of the Light Aeroplane Clubs under the asgis of the Air Ministry, throughout various parts of the country. We propose publishing each week, under the above heading, secretarial notes as to the work being done by the various clubs, together with other items of general Light 'Plane Club interest. For the benefit of those of our readers who may be interested in the Light 'Plane Club movement, we give below the names and addresses of the secretaries of six of these clubs which, it is hoped, will shortly be in active operation. From one of these—Newcastle-on-Tyne—we have received a few notes on the progress so far made, which we also publish. We shall be pleased to have reports regularly from Club Secretaries, or those directly connected with new Light 'Plane Clubs, so that by keeping our readers informed on this matter the whole movement may be helped forward to the benefit of the clubs and the popularising of " that Air feeling." lisLed a new French speed record by averaging 393 km./h. (246 m.p.h.) over the 3 km. course. The " Ferbois " racer, type V.2, is shown in a photograph, and also, from a different point of view, in a sketch. The fuselage is of circular section at the maximum cross-section, flattening out to an oval shape at the stern. All wing and tail surfaces are faired into the fuselage by aluminium covers, and, altogether, everything possible has been done to reduce corners and everything that might add to the resistance. The undercarriage is quite different from that of the metal machine shown at the last exhibition, which was, it may be remembered, in the form of a single large central streamline " leg," into the lower end of which the axle fairing was built. On the V.2 there is a flat tapering leg on each side, made of multi-ply wood and coming almost to a point at the lower end. The divided axle works in a slot in the leg, and simple rubber shock-absorbers are used for springing the wheels. The cantilever wings are of all-wood construction, and Lamblin radiators are fitted under the lower surface. The 450-600 Hispano-Suiza engine is entirely cowled-in, the streamlining being completed by a spinner over the propeller boss. Needless to say, the V.2 is by far the fastest machine in the show. The makers claim it to be the fastest machine in the world, but although this may be true, it still'has to be proved. The main dimensions are : Length o.a. 6-7 m. (22 ft.) ; height, 2-3 m. (7 ft. 6 ins.) : wing span, 9-9 m. (32 ft. 6ins.); wing area, 11-6 sq. m. (124-5 sq. ft.). Weight fully loaded, 1,175 kgs. (2,580 lbs.). Wing loading, 20-8 Ibs./sq. ft. (To be concluded.) <s> <s> CLUB DOINGS Newcastle-on-Tyne.—Alex. H. Bell, Esq., Hon. Sec, Newcastle-on-Tyne Light 'Plane Club, County Hotel. Yorkshire.—Prof. G.

Pilot Killed As a .result of an accident, at Upavon, to an Avro 504K of the Royal Air Force Central Flying School, on December 3, Pilot Officer Douglas Elphinstone Gam, the pilot, was fatally injured and Denham Brown Waight was slightly injured. An Important Judgment AN important decision concerning the responsibility of air transport companies has been given by a Paris Tribunal in connection with an accident to one of the cross-Channel The Secretary of the Newcastle-on-Tyne Light 'Plane Club informs us that the Club has now been definitely formed and a Committee elected. The approval of the Air Ministry has been received, and the Club hopes to receive the subsidy, under the Light 'Plane Scheme, in due course. Headquarters have been established at the County Hotel Newcastle, and two well-attended and enthusiastic meetings have already been held. A series of lectures, to commence immediately, is being arranged, and as many subjects relating to Aeronautics as possible will be covered. When the flying ground is prepared it is intended to form a glider section and a model section. A very suitable site, just out of the City, has been selected as a flying ground, and negotiations regarding obtaining the use of it are in progress. The interest which the formation of the Club has aroused in the district is very gratifying. The subscriptions to the Club are as follows : Flying Members, £3 3s. ; Non-Flying Members, £2 2s. ; Student Members, £1 Is. For each there is an entrance fee of a similar amount. <$> 0 machines which fell into the sea off Folkestone on June 3, 1922, when the pilot and two passengers were killed. Madame Caroll, the widow of one of the passengers, sued the French company to which the 'plane belonged for 500,000 francs damages. The Court decided that air companies have the same responsibilities towards their passengers as land and water transport companies, but since the pilot of the- machine in question was in good health, and since the aeroplane itself was in good working order, the mishap was purely accidental, and consequently the company could not be held responsible, and the claim was therefore rejected. Roumanian Royal Aero Club's New Headquarters THE' Royal Aero Club of Rou mania has now moved into new headquarters, as follows : 9, Rue Clemenceau, Bucharest. The General Secretary .of the Club is Lt.-Col. Aviateur Andre Popovici. R.A.F.
