AUGUST 7, 1909. firstly in order to avoid a long run (which with the Wright flyer is limited by the starting-rail), and secondly in order to avoid regaining the ground at an unnecessarily high speed. The above considerations only take into account horizontal winds dead ahead and dead astern. Horizontal winds blowing obliquely have to be considered in respect to their resultant in the direction of flight. Winds with an upward trentl, by contributing independently to the lift of the machine, are a case apart. It is sometimes asked, can a flyer travel with the wind slower than the wind ? This is only possible by heading against the wind, under conditions such that the thrust of the propellers is sufficient to maintain the necessary velocity for flight through the air, but is yet inadequate to fully overcome the drifting effect, relative to earth, of the wind on the machine ; in other words, the flyer is being blown back while trying to advance. It is very instructive in this con- nection to watch the flight of birds on a windy day in open country- near the sea, and to observe the tremendous velocity they acquire directly they turn tail to the wind after they have been trying their utmost to fly against it.—ED.J AN ODE TO AVIATORS. To the Editor of FLIGHT. SIR,—As one of the large army of (unengined) inventors for long interested in the problem of flight, I venture to contribute the enclosed, one of those brilliant (?) inspirations which, if it does not assist others to fly, may at least help them to flee. Yours truly, Southsea. PERCY A. K. BROCK. It was the Frenchman Bleriot Who scorned to take the Ferry O, But climbed forthwith into his monoplane. He did not make a rumpus, He did not take a compass, Or e'en a stout umbrella should it rain. Oh ! this historic sally, From the neighbourhood of Calais, Was certainly what folks call " Pretty Fly " ; To get twice half-seas over, And then tell the Port of Dover, " Doveriah, Doveriah, I am dry." It is neither stuff nor blarney, Monsieur Bleriot's Anzani; His pluck, and will, and luck, and other things, With just-mentioned gem of motors, Helped him soar above the bloaters, Triumphantly to England upon wings. This man, who does not boast When he first descried our coast, Proved his word to be his bond for woe or weal; And by virtue of this rule, "\~.~.-.:_ Scooped the profit of the pool, •' - While refusing to be tempted by a Deal. .',':'!': It has since appeared in print, A policeman made a sprint, To receive the man who did the very best; And the peeler did not dim it, With a lecture on speed limit, Though he may have said, " It's time, sir, fora rest." Poor Latham, all have said it, Deserves the fullest credit And sympathy for troubles on his flights ; And all aviation songs Would be radically wrongs, If they failed to somewhere touch upon the Wrights. Be the day a rough or calm un, Here's a toast to Henry Farman, Who has English somewhere lurking in his veins; And any who find fun in My excruciating punning May pass to the deserving what remains. But we all must give to Bleriot, Who would not take the Ferry O, And left a fast destroyer on a run, This fame-emblazoned panel— Louis Bleriot flew the Channel— What no man on earth before had ever done. AEROPLANE PROPELLER TEST. To the Editor of FLIGHT. SIR,—With reference to the test of aeroplane propellers in your Journal, these tests do not seem to me to be at all practical or con- clusive. It is quite evident that to obtain a fair result the speeds should be varied to suit each type of propeller, and we therefore propose that another lest should be made with larger propellers, of, say, 24 ins., 38 ins., or even 84 ins. We will provide the propellers and motors of a proper speed to drive them, and our competitors should provide their own. Will you kindly act as judge ? Yours faithfully, THE WATFORD ENGINEERING WORKS. CROSS-CHANNEL BALLOONING — MR. P.SOUVESTRE'S TABLE. To the Editor of FLIGHT. SIR,—You published in FLIGHT on 17th July an incomplete account of over-sea balloon voyages. Do you consider the two following unworthy of recording. Maldon to Arras. J. Simmons. June nth, 1882, when I broke my leg. 12 minutes crossing the Channel. Maldon to Flushing. J. Simmons and myself. July 31st, 1883. The first time, and I believe the last, that a balloon ever started from England and landed in Holland. Yours faithfully, CLAUDE CHAMPION DE CRESPIGNY, BART. [We are glad to have Sir Claude Champion de Crespigny's addi- tions to Mr. Souvestre's table. Thus by the help of our readers we shall hope to obtain a really complete list, when we shall re-publish it in amended form.—ED.] FABRICS FOR AEROPLANES. To the Editor of FLIGHT. SIR,—It would interest me, and possibly many others, to hear of an aeroplane fabric which is manufactured in our own country, and which is reasonable in price. The regulations governing certain competitions demand that the competing machines should be English. Yours faithfully, s. P.S.—I am waiting for a high-class material to cover the planes of my machine. ® ® ® ® ••-••••• v NEW COMPANIES REGISTERED.
