CLOUD-WRITING [To the Editor of the SPECTATOR.] SIR,—The fact that
sky-writing—surely more correctly desig- nated, as in the Spectator, " cloud-writing "—was successfully employed in the recent Presidential Election in Germany, suggests that it may perhaps ultimately be found useful in England for other purposes than war signals and advertisement- _ Meantime, it should not be forgotten that sky-writing, if so it is to be called, can do nothing worse than hide for a few minutes the infinite glory of the stars, and need cause no more permanent disfigurement to the countryside than a display .of fireworks at a village feast. Moreover, the expense of projec- tors and other apparatus will undoubtedly prevent it being very extensively used even for advertising, except in the neighbourhood of large towns ; and there, only when atmos- pheric conditions are favourable. Sky-writing in daylight, effected by aeroplanes which trace out letters of the alphabet in white smoke against a background of azure blue, is a really beautiful sight, as well as a striking exhibition of flying skill ; but I imagine that it is decidedly dangerous, and far too costly to be frequently employed.—I am, Sir, &c., Hadfield Square, Eastbourne.
