JyGHT] Therefore it is obvious that a fairly large sized motor would be required, the weight of which, when taken into account with that ot the necessary accumulators, &c, would greatly exceed 2 lbs. or thereabouts. I should advise him to use an elastic motor ; 40 to 50 strands of i-g square elastic, which would weigh approximately 5 to 6 ozs., would be plenty, I should think, besides allowing a safe margin for the weight of the propeller and the various accessories. Stoke Newington. B. H. LONGSTAFFE. PETROL ENGINE MODELS. [560] I am making a J scale Farman model, to which I intend fitting a small petrol engine. Could any of your readers tell me ol what horse-power this engine should be, and whether any great success has hitherto attended scale models driven by petrol engines. A WATSON. © ® ® ® TEACHING THE, LAY OF THE LAND. ONE of the first points which the uninitiated balloonist notices on looking down on the land above which he is floating, is the fact that it fails to arouse any sense of recognition by its geographical features. The truth of the matter is that man has never been able to study the surface of the earth on a realistic small scale, for maps, even when highly coloured, are no more than symbolical at the best. There is the possibility of a change in the future, however, which should be thoroughly in keeping with the needs of modern education, as the Geographical Model Works, of Newcastle on-Tyne, are at work on accurate relief maps which should do much to prepare the student for a knowledge of the earth as seen from the air. The immediate value of these maps relates, of course, to their geological import, and that which has first been produced, a photograph of which we give, shows the district of Ingleborough, near Settle, which is considered by Professor Hughes to be the most interesting geological spot on the earth's surface. Quite apart from this, however, it is to the general principle of teaching " contour" which, in the interests of the world of flight, we find cause to extend a welcome and wishes of success. ® ® ® (& Aeronautical Patents Published.
