(Concluded from page 229.) with shutters operated from the cockpit, is so mounted as to be unaffected by engine vibration, even in the case of a badly missing engine. It might also be mentioned that the complete wing structure, and, if desired, the engine unit, can be removed after undoing eight bolts. As already mentioned, the petrol tank is mounted in the hull, and the fuel is fed to the carburettor by pressure from a pump. This is the usual arrangement on seaplanes, and for some reason has not been found to give as much trouble as does a similar petrol system on a land machine. One would prefer gravity feed, but it is difficult to see how this could be attained, and practical experience appears to indicate that it is not really necessary on a machine of this type. The wings are of usual design, with one pair of inter-plane struts on each side. Bracing is by stream-line wires. Both upper and lower planes are provided with ailerons, controlled by cables in the usual way. Attention has already been called to the method of mounting the engine independently of the wings, and apart from this fact the wings do not possess any unusual features. The fittings are very robust, and treated ro withstand the action of salt water. Also they are very accessible and easily renewed. The machine is steadied laterally, when on the water, by wing tip floats of the usual Supermarine type. Figures relating to the performance have already been given. The following are the main characteristics of the Supermarine " Sea King " :— Length of hull, 24 ft. g ins. ; wing span, 32 ft. ; chord 5 ft. 9 ins. ; gap (maximum), 6 ft. ; area of main planes, 352 sq. ft. ; weight of machine (empty), 2,115 lbs. The useful load is composed as follows :—Pilot, 180 lbs. ; Lewis gun and six double trays, 100 lbs. ; instruments, 20 lbs. ; equipment, 30 lbs. ; petrol (50 gallons), 365 lbs. ; oil (4 gallons), 40 lbs. ; total useful load, 735 lbs. Weight of machine fully loaded, 2,850 lbs. Wing loading, 8.1 lbs, /sq. ft. Power loading, 8.4 lbs./h.p. m m m m PERSONALS Death Lieut.-Col.

THE LONDON AERO-MODELS ASSOCIATION A VERY successful meeting was held at Headquarters, 20, Great Windmill Street, Piccadilly, W-> on Thursday, the 13th inst. Four new members joined the Association, namely, Mr. Houlberg, Mr. W. Hersom, Mr. Brough and Mr. Bedford; all these gentlemen are areo-modellists of repute and already have proved themselves energetic supporters. The competition which was to have been held on Sunday, the 16th, at Wormwood Scrubs, was postponed on account of the unsuitable weather conditions, there being a wind estimated by those present at over thirty miles per hour. There were approximately forty members present and in spite of the conditions many of the members unpacked their models and gave an excellent demonstration of what model aeroplanes can do in a high wind. The most prominent display was given by the members from Leytonstone, and also Mr. L. Grey, whose enclosed model gave wonderful performances, to the admiration of the general public who attended in large numbers. The competition will be held on Sunday next, the 23rd inst., at Wormwood Scrubs, at 11 a.m., when it is hoped that members will put in an even better attendance than they did last Sunday. Meetings are held every Thursday at Head quarters, 20, Great Windmill Street, at 7.30 p.m., where Mr. A. E. Jones, Hon. Sec, or the Assistant Secretaries, Mr. Hatfull or Mr. Rippon, will be pleased to give full particulars of the Association. m. m m m PUBLICATIONS RECEIVED Annual Report of the Smithsonian Institution, 1919.
