You must have a sense ofrelative values and proportions and knowthe comparative weights and strengths ofthe various articles used. The aeroplane with its light wires andthin framework is quite as strong andheavy, when compared with the air inwhich it moves, as a boat is when com-pared with the water in which it floats,which is eight hundred times denser thanair, or the structure of an automobile.

READY FOR THE START. function for which they are used with-out unnecessary weight or size, and so itmust be with all the other parts, whetherof wire, metal, or wood. It must be borne in mind, however,that the entire proportions of the designmust be adjusted to an element eighthundred times less dense than water, andharmony in weight and strength mustexist through all elements of the struc-ture. It is easy to see the fundamentaldifference between an aerial motor andone of marine or automobile type. Thesame difference is evident in a well-builtframe and chassis. Another element enters into the con-struction of an aerial motor, which isthe comparatively constant speed atwhich it is required to run; there areno shocks or jars caused by changinggears or reversing the direction of thethrust, so much lighter construction canbe used. The main structure of theaeroplane itself is lighter than the frame-work of water and land vehicles, in re-gard
