record for the month with 37 sees. The hest added flights for the month being thus : J. P. Worrall, 6IJ ; K. K. Rayner, 58J; G. H. Dewsnap, 46*. Windsor Viod^i <\ero Club (10, ALMA KOAD, WINDSOR). NOVEMHER 2nd, Tractor meet in Home Park, 2.30. Monthly• Report.—During the pa<>t momh all the members have been experimenting with tractors. Two txflle models, a trastor biplane, and three tractor monoplanes have been brought out, and two of them, S. Barton's "Ant -inette, and S. Carom's "A. 1). Clark 76," have proved very successful; flights of 120 yds. being obtained on many occasions. E. D wsett's sca'e "Av'o" has not yet been successful. No practice has been possible with the glider, owing t-> the absence • f a good wind. Stanbrook, F. Camm, Hamblin and Parsons are constructing various models. Vors«mr.c le.^. 1 viodei s^c. (S3, WEST STREET, LEEDS). NOVEMBER 2nd. Poppy Fields, Beeston. ® ® ® ® CORRESPONDENCE. Correspondents communicating with regard to letters which have appeared in FLIGHT, would much facilitate ready reference by quoting the number of each letter. The Fatal Dive. [1660] In letter (1632) of Thomas Preston Brooke, is the state ment that Paul Peck's machine " pitched downward with its elevator raised to the limit," and in the article, " Parke's Dive," in your issue August 31st, is the statement that "at point C he drew elevator lever hard back against his chest" . . . and "from C to D (against the wind) the machine was completely out of control, diving headlong at such a steep angle that all spectators described it as vertical and stood, horror-stricken, waiting for the end." I should be glad to hear if Mr. Brooke can give the direction of the wind at the time of Peck's accident. Was Peck heading into the wind at the lime? Also if eye-witnesses of Oxley's, Fenwick's, or other accidents due to dives would kindly forward particulars, stating if machine was heading into the wind at the time ; it would be information of the greatest value. To me it appears that even stable machines must not be expected to flatten from the vertical when heading into the wind. It is significant that when Lieut. Parke, in spiralling, got with the wind he was able to flatten out. It is a reasonable assumption that if a machine drifts in winds when "beam on" owing to the side elevation areas, it will be liable to drift the more when vertical, having a greater plan area exposed, it will be liable to be blown backwards when diving head to the wind. The fact that no backwards drift has been observed does not disprove this theory—the tendency is there, but evidently the pulling of the elevator up to its limit is sufficient to keep the flight path vertical. To me, it appears that the elevator is " used up " in preventing drift, and leaves nothing in hand for flattening out with. Spiralling then from up wind to down wind would bring the wind pressure under the wings, and the drift factor would be with the desire of the pilot to flatten out. There must be a critical angle from which it is impossible to flatten out against the wind, I cannot and refuse to believe that all dead pilots lost control, this behaviour of a machine (when diving) in not flattening out when called upon has not been satisfactorily explained by assuming the pilot lost control, but we have evidence that Peck's and Parke's elevators were hard up to the limit, and in the latter case against the wind. Parke was not able to flatten out against the wind ; more information from eye-witnesses as to the flight path being into the wind or not would help greatly to substantiate my theory. Southport. JOHN GAUNT. Clutches on Aeroplanes. [1661] With regard to the arrangements of the engine, &c, on an aeroplane, would it not be possible for the engine and propeller to be connected by means of a friction clutch on the same principle as a motor 'bus. Thus the engine could be running at top speed, and the propeller stationary. This would render unnecessary the use of a lot of heaving, straining mechanics hanging on to the tail of the machine, and if the engine were fitted with a starting lever inside the pilot's cabin it would do away with the horrible and dangerous performance known as " propeller swinging." Barking. H. OLIVER. Brakes on Aeroplanes. [1662] In your comment on letter No. 1647, by Lieut. E. R. Knox-White, you say that the only aeroplane using a brake to your knowledge, is the Cody, which overlooks the claims of the Breguet biplane. I was present when that fine pilot, M. Moineau, put two Gnome- Breguets through their paces for the Government, and I assure you that the brake was so effective that he was enabled to pull up the machine, a none too light construction, travelling at anything between 55 and 60 miles an hour, in 25 yards or so. Wishing FLIGH r every success in its new life. Farnboro'. L. E. MORELAND-GILLMAN. [We are compelled to hold over other correspondence.—ED.] NOVEMBER 2, 1912. AERONAUTICAL SOCIETY OF GREAT BRITAIN. Official Notices. Elections.—Lieut.-Col. R. de Villamil (Member), John Johnston (Student), and W. M. Fane-Pendlebury (Foreign Member). Aeronautical Examination.—The Council have under con sideration a proposal that an elementary examination in aeronautics be instituted by the Society. Before proceeding further in the matter the Council would be glad to receive notification from anyone who would be desirous of sitting for such examination. Letters should be sent to the Secretary, at 11, Adam Street, Adelphi, W.C. MeetinRS.—The first geneial meeting of the Society for this session will be held on Wedne>day, November 13th, at 8.30 p.m., at the Royal United Service Institution, Whitehall, when Mr. A. E. Berriman, A.F.Ae.S., will read a short paper, to be followed by a discussion, on " Aeroplanes in the Light of the Military Trials." Leading constructors, military officers and others have promised to attend. The second meeting will be held on Wednesday, November 27th, at 8.30 p.m., R. U.S.I., when Brig.-Gen. F. G. Stone, R.A., will read a paper on " Aircraft as Targets for the Artillery." BERTKAM G. COOPER, Secretary. ® ® ® ® Bargains for Model Makers. WE learn from Mr. Weston, who is again very active in the model world in connection with the Star Model Aeroplane Co., that they have purchased all the W.H.C. patterns and accessories. Our model advertisement columns show that Mr. Weston is offering an excellent selection of model materials. A New Catalogue. MESSRS. AERONAUTICAL ACCESSORIES, of 39, St. James's Street, Piccadilly, W., are making a speciality of clothing, &c, for aviators. A new li-t which they have published gives particulars of the Warren safety helmet, leather and other suits for fl>ing, goggles, top boots, gauntlets, and other things specially suitable for use by aviators. The "Dally Mirror" War Map, IN order to follow intelligently the course of events now taking place in the Balkans, it is necessary to have a good map, and that issued by the Daily Mirror is one of the best for this purpose. When it is stated lhat it is produced by Mr. Alexander Gross, of the Geographia Designing and Publishing Co., it will be understood that it is a very clear and easily read map, which is a mo.-t important point where the names of places and districts appear rather awful to a plain Anglo-Saxon. The price of the map is 6a?. net on paper, or mounted on cloth is. 6d. net. ® ® ® ® PUBLICATIONS RECEIVED. The "Daily Mirror"" War Map of the Balkans.
