1/ycEE) The latest thing in fly! ng caps by Messrs. Harrod, of Brompton Road. It is of tan chrome leather, lined with chamois, with beaver fur in the top half. Note specially the straps which make it possible of adjustment to any size for comfortable fitting. Altogether a very fine example of headgear. The price is £2 2s. The Aerofoil and the Screw Propeller. STUDENTS of aeronautics will doubtless welcome the action ul Ihr liiMiiiitiim of Automobile Engineers in publishing the two papers, read last session by Mr. F. \V. Lanchester, in a single volume. Both " The Aerofoil: in the Light of Theory and Kx- peritnent" and "The Screw Propeller" are valuable contributions to aeronautical literature, anil in a sense complementary to each other, and it is of great assistance to have the important matter which they contain available in a convenient form. In addition the book includes the discussions which followed the reading of the papers. The volume is bound in a substantial cloth cover, and the I.A.E. have been wise to fix on a moderate price—y. 6d. net. Copies can be obtained from the offices of " FLIGHT" for p. lid. post free. A new type "Auster" aeroplane and seaplane wind-shield, which is lifted with Triplex glass. The extreme width is 22 Ins., and the total weight 3 lbs. 7 ozs. If you require anything pertaining to aviation, study "FLIGHTS" Index to Advertisers and "FLIGHTS'' Buyers' Guide and Trade Directory, which appear alternately in these pages—one each week. MARCH 2, 1916. CORRESPONDENCE. Flying—Science or Art. [1917] With reference to the article by the "Dreamer" and letters Nos. 1910 and 1911, I do not agree with " One Interested in Flying " re his remarks on " pushing the rudder bar and the machine turns by science" Possibly he has forgotten the possibility of side slips, &c, which only the art, or skill, of the pilot can prevent, aided, of course, by a scientifically built and controlled machine. If there is no art in anything there can be no genius, yet genius is an acknowledged fact. Take as an example an instrument, two people learn ; both have the same tuition, practice, &c, yet one becomes a master and the other remains & pupil, not because of lack of trying or love of his instrument, but because it comes to one as intuition. while the other has to be repeatedly taught a fact before he masters it. The one has genius, or, if not genius, at least remarkable aptitude. The same thing in aviation ; the man whose every move is graceful and smoothly carried out, and who can coax "his machine like a tender-mouthed horse, surely he is not in the same class as the man whose moves, though perfectly accurate and correct, are roughly and jerkily carried out. No ; one is an " aeroplane artis-," the other a "well-trained aviator." Thanking you and with every good wish to your fine paper. Melbourne, Australia. KENNETH WALLACE-CRABBE. ® ® ® ® The R.F.C. Hospital. THE Hon. Treasurer of the R.F.C. Hospital, 37, Dorset Square, N.W., acknowledges the receipt of a donation of £$ from a reader of " FLIGHT." Look for the Gold Seal on Triplex. WHEN buying goggles or anything else in which " Triplex " glass is utilised, care should be taken to see that each piece of glass carries the little gold seal with the "Triplex" monogram S.T.G. The importance of this warning is emphasised by the fact that the Company recently had a pair of goggles returned to them, which were sold as " Triplex," but were in fact just plain glass. The Price of "Shell." USERS of "Shell" are reminded by an announcement of the Asiatic Petroleum Co., Ltd., that they should be able to purchase everywhere, Shell motor spirit in two gallon tins to the extent of one-third of their normal consumption lat the old prices, which for England and Wales remain at: Shell, 2s. 2d. per gall. ; Shell II, 2s, id. per gall. ; Crown, 2s. per gall. In Scotland and Ireland the prices are one penny more. ® ® ® ® Index and Title Page for Vol. VII.
