fastest French and Britishmachines were found to be the mostformidable fighters. Hence they wereimitated (and fatally bettered) by the(■ermans and Austrians. And Yet, the Aeroplane IsUnchanged It is surprising how little the generalappearance of the aeroplane has changedduring its entire history, in spite of itsmar\-elous development.

But theaeroplane is such a simple de\ice (andhas been found best in its simplest forms)that the phenomenon is easih explained.There are onl\- two striking outwardsigns of improxement; the streamlinel)oat-l)ody, enclosing e\erything andminimizing head-resistance, and thesolid, inflexible appearance of the wings,due to the invention of enamels whichstrengthen and shrink the cloth co\eringand make it as smooth on both sides asJapanese lacquer.

Before the war, only two or three machines in an endurance contest, in which perhapstwenty aeroplanes were entered, reached their dcstin.ition. But now we hear otflocks of fifteen flying from Calais to K.irlsriilie on a lionib-droppinR expedition andreturning safely. Surely tlie war has taught ui much about flying macliinc construction Popular Science Monthly 527 attained by the aeroplane that has itsprcjpelier in front of a Ijoat-lxxiy.Thanks to the tractor-screw the IjipUmchas (icvcioped as much speed as tiiemonoplane.
