ANOTHER SCOTTISH PRlZE-£1,000. Jo the Editor of FLIGHT. SIR,—I take pleasure in announcing that I have just been success- ful in arranging a prize of ,£I,OOD for a flight from Edinburgh to Glasgow. This handsome prize has been given by the proprietors, The Daily Record and Mail, Glasgow. Fuller particulars will be furnished later, but meantime might say, that the principal condition will be that it be done by a Scotchman on a Scotch-built machine. This, with the ^500 prize on offer for a successful flight across the Forth near the Forth Bridge, will give our Society a splendid stimulus. Our efforts are meeting with good success. Yours faithfully, WALTER G. DUNCAN, Hon. Secretary pro tern., The Scottish Aeronautical Society. : ^ PROPELLERS. ^ ' .••;. To the Editor of FLIGHT. SIR,—In the article by John Squires, on p. 393 of your issue for July 3rd, I see that he somehow argues that the driving power of a propeller varies as the cube of the pitch. How is this ? Should it not be the square of the pitch ? Further, it seems a pity the author did not use a few symbols in his mathematics, as a simple formula connecting driving power with speed, pitch and area would show much better the effects of varying each of these factors than the sixteen unwieldly paragraphs on p. 394. Yours truly, R. C. CLINKER. [The basis of Mr. Squires argument lies in the last paragraph but one on p. 393. The author is referring to power—not thrust alone.—ED.] A MISLEADING ADVERT. To the Editor of FLIGHT. SIR,—On reading an advertisement in your last week's issue of FLIGHT, the number of which was Box 6,188, the advertiser states he wishes to invest capital in the aeroplane business. On reaching his office by appointment, I was surprised to find instead of wanting to invest capital he wishes to sell an air-cooled engine which he believes to be an Antoinette. I merely write to your paper in the interest of readers warning them of what is in my opinion a mis- leading advertisement. As I stated clearly, I was desirous of investing six or seven hundred pounds in the business. Trusting you will insert this in your valuable columns, Youis faithfully, H. A. PROPELLER ADVERTISEMENTS. To the Editor of FLIGHT. SIR,—We notice that the Cochrane Propeller Cx are advertising rn FLIGHT that they " have challenged and beaten allcomers," We do not think they have any right to make such a statement in view of the account of the tirial against the Beedle propeller which you were good enough to insert in one of your recent numbers. Yours faithfully, : THE WATFORD ENGINEERING WORKS. PROPELLER CHALLENGE ACCEPTED. To the Editor of FLIGHT. SIR,—Referring to a letter in your issue of September 4th from Mr. Sidney H. Hollands, we have accepted his challenge, and understand that Mr. Hollands is making arrangements for an aero- plane so that our respective propellers can be tested upon the same machine. Yours faithfully, THE WATFORD ENGINEERING WORKS. UNDIVIDED REPRESENTATION OF FLIGHT. To the Editor of FLIGHT. SIR,—Although I do not at all agree with your remarks re the Aeroplane Club, of which I was the founder, for the simple reason that I started the Club with a view to arousing some interest in this country in " heavier-than-air machines," I think if you will look at it with an unbiased and unprejudiced mind, and apart from the fact that you are the official organ of the Aero Club, you must admit that there was very little done, and very little interest shown at the time I founded this Club. I did so simply to shake people up and interest them in aviation, and I think you will agree that it certainly did this, in more ways than one. After having founded the Club, Mr. Wallace, K.C., the President of the Aero Club, and myself, did everything possible to try and amalgamate the two bodies, seeing that it might be for the good of aviation. I had, and have, no axe to grind whatever in the matter, and was prepared to hand over our interests, together with the Committee of the Aeroplane Club, to the Aero Club ; but, after promising to 563
