IAH appear prohibitive and any figures given by you as to the compara tive safety of flight will, we feel sure, meet with the respect they •deserve from the insurance offices. . . We may say that we have made a particular study of av'atlo° rkks and quite appreciate that any diminution in the rates would lead to increase of business and, therefore, the interests of aviators and the interests of insurance brokers are identical in this case. We truit that you will excuse our taking up so much space in your valuable pa]>er. DEIGHTON PATMORE AND CO. 43, Leicester Square, W.C. Top Pressure on Wing Surfaces. -tI54IJ 1N reference to the statements that you have recently published in your excellent journal with regard to the insufficient strength in the upper trussing of monoplane wings, it has occurred to me that in addition to monoplanes, those biplanes that ate fitted with what is generally known as extensions, should come under the same category. Even though the recent disclosures have suggested •a hitherto unrecognised cause for many of the accidents that have marred the progress of flight, it has always seemed to me that these extensions were by far too weak, and in rough weather I have always looked at an extension biplane in flight with a certain amount of suspicion and have felt anxiety for the occupants in case one of these flimsily braced extensions should collapse. As you know, two methods are employed in bracing them. One method is to erect a pair of masts at the end of and above the cellule, from which the extension is braced by tension wires as would be a mono plane wing. The other method is to support the extensions from the end of the bottom plane by two steel tubes. In this latter case especially I think something ought to be done to make for greater strength, for I hardly believe that two steel rods of such small cross- section and of such relatively long length would be sufficient to withstand much compression. Wishing you a continuance of the success your paper has all along met with. EGA V AS. The Aircraft factory Aeroplane. [1542] I have heard very glowing accounts from acquaintances who have seen the Army B.E. 2 Aeroplane in flight, which is said to be far in advance of all other machines as regards steadiness, sjieed and general appearances. As there is so much talk just now regarding England's backwardness in aeroplane construction, especially in relation to the War Office, I should like to know if there is anything really wonderful about the B.E. 2. Harrow. EDWARD H. QUINN. Redivalls Model. tJS43l ' should be much obliged if your correspondent, Mr. W. II. Booth (1504), would inform me as to whether his Redivalls patent refers to models having a diamond-shaped piece in the centre of the main plane or whether it refers to models having upturned tips to the main plane. Crawford Street, W. B. F. HUSSEY. British Manufacturing Firms. ,[1544] I notice with some interest that the Farman advertisement appearing in FLIGHT now bears an English address and also the title of a new company, with an admirably chosen English name —"Aircraft." Perhaps you will permit me to enquire whether the Aircraft Co. intends actually to follow the trade implied by its so well chosen name or whether it is merely going to import foreign-built machines from France. 1 have an interest in writing that is doubtless common to other readers of FLIGHT who are watching with more than a little concern the policy of the Government that you very justly defended in your last issue. We are all agreed, I think, that the Government owes it to the Flying Corps that the pilots of that new arm should have an adequate opportunity of obtaining personal experience of original foreign-built machines. But, we all want to hasten the day when it is the British workman who is receiving the wages for construction, and it occurs to me that that day is likely to be more expeditiously reached if the Govern ment are in a position to buy British-built originals of the foreign machines they require from actual British firms duly manufacturing under licence. In these days of small beginnings even the outsider likes to take a personal interest in commerce and, sad at the loss of the Aeronautical Syndicate, I for one should welcome the Aircraft •Co. to fill a gap in the ranks of British construction concerns— especially if they are going to employ Englishmen at the work. "CRAFTSMAN." MAY 4, 1912. Aviation at the Naval Review. LIEUT LOVGMORE, R.N., recently made a visit to Portland, with the object, it is understood, of finding a suitable piece of ground to serve as a centre from which to make flights in connection with the Naval Review and Manoeuvres on Monday and the following days The battleship "Hibernia" has been fitted up with a launching platform, and is taking four machines, including one monoplane, from Sheerness to Portland for the Review. More Deperdussins for the British Army.i THE War Office has ordered from the British Deperdussin Aero plane Co., Ltd., several more Deperdussin monoplanes similar to that delivered to the Admiralty recently. The machines will be built in London, and will be delivered within the next four or five weeks. A Lilt to Brooklands Track. COMMENCING on Saturday next, Mr. H. H. Beach, ot the Holstein Garage, Weybridge, has arranged to run a motor waggonette between Weybridge Station and the Byfleet entrance to Brooklands track. The vehicle will run on Sundays, and on any day when there is sufficient attraction to draw visitors. The fare will be one shilling each way. A Unique Signpost. ON the main London to Brighton Road at Bromley South, a curious signpost has recently been erected. One of the three directing arms, having the inscription Hastings and Paris, carries a model of a Bleriot monoplane ; another, pointing to London and John O'Groats, has a racing motor car, while the third arm, directing to Croydon, is surmounted by a motor-bike. The post also carries advertisements referring to the Bromley South Motor Garage, &c. and it is surmounted by a model of a biplane, arranged in weather cock fashion. Shell Spirit for Aviators. WE understand that during his trip from Holyhead to Dublin Mr. Vivian Hewitt used Shell motor spirit, and Lieut. A. M. Longmore, R.N., used the same spirit during the flight which won for him the Mortimer Singer Naval prize. ® ® ® © Aeronautical Patents Published. Applied for In IBM. Published May znd, 1912. 9,445.
