Nearly every member present had a machine to fly. Messrs. Rippon, Moranne, Lansdown, Whelpton, Burchell, Burchell, Jun., and others made several flights and obtained plenty of prac tice in view of the forthcoming competitions. The enthu siasm of the Hampstead members of the L.A.M.A. appears to be increasing weekly. Great credit is due to the recently joined members of the Association who are building models, the workmanship comparing favourably with that of the older members. SIDE-WINDS SIR ROSS SMITH, acting no doubt on the results he obtained with the Smith aviation instruments he used during his Australian flight, is. we understand from S. Smith and Sons, having the Vickers " Viking " on which he will attempt the flight round the world fully equipped with Smiths' instru ments. These will include the following : Revolution indi cator, air-speed indicator, altimeter, oil and petrol pressure gauges, Cambridge radiator thermometers and Campbell- Bennett aperiodic compass. And, of course, he will use K.LG. sparking plugs.
