A1PP05T BY DOUGLAS B. ARMSTRONG -.-_.,. The " Aerosemist " REVIEWING a newly - published treatise on "Aero StampCollecting," Mr. Gavan Duffy, one of the foremost exponents of the air postage cult, coins a new definition for the collectorof air mail material—he dubs himself an " aerosemist." The expression is not a particularly engaging one, but it isby far the best that has been put forward as yet. Certainly it is preferable to the term " aero-philatelist," which carrieswith it the implication that the collecting of air post items is merely a side line of philately—a point of view that calls forthvigorous protest from Mr. Duffy, who comments :•— " The two pursuits are, of course, as distinct as chemistryand biology, or, shall I say, as the theatre and the kinema, and there is no imaginable reason why the peculiar standards ofstamp collecting should be forced upon the more vigorous and up-to-date enthusiast for air mail. The one finds hismain interest in the stamp as a stamp, the other in the stamp or entire as a development in aerial mail." This is the view that has been advocated consistently inthis column, and is shared, we believe, by the majority of aerosemists, many of whom have no interest in the study ofphilately per se. Danzig ErrorA,SCARCE and interesting error of the 5,000,000 mark aero stamp of Danzig, recently chronicled, has been brought toour notice by Mr. W. E. Hughes. It arises, apparently, from the insertion of a wrong cliche in the electrotyping forme, theseventy-third stamp in each sheet being of the original face value 10,000 ink., instead of 50,000 mk. upon which the" 5 Millionen " surcharge is normally applied. As it is understood that flying has been suspended for the winter andthe air stamps are accordingly rendered obsolete, it is possible _ that this aero error will prove elusive. Syrian Air PostsFROM the Syrian State of Lebanon comes a curious semi- official air post label in the form of a roughly executed mapof the province, marked with the main routes, railway and air lines, printed in red and blue, with inscriptions in Frenchand Arabic reading " Syrie-Leban—Aviation Civile 1 Piastre Syrienne." The design also includes an aeroplane flying over , the sea, towards the coast.i- Previous issues of Syrian air post stamps have all been made under military auspices, in connection with the army air linesbetween Aleppo and Alexandretta, Damascus and Swedia, Damascus and Palmyre, Latakia and Horns, and Aleppo andDeir el Zoor. The first set of three values overprinted " POSTE PAR AVION " on ordinary postage stamps of theFrench military occupation appeared on December 1, 1920. This was followed in June, 1921, by a second series, similarlyoverprinted, but upon different denominations. In October of the same year the form of overprint was modified to the singleword " AVION," impressed vertically in small Roman capitals.As these stamps were never on sale to the public, they are extremely hard to obtain in unused condition. , Proposed U.S.A. Speed Stamp . ACCORDING to the American press, the Aeronautical Chamberof Commerce has proposed to the United States Post Office Department the creation of a special speed postage stamp toensure transmission by aeroplane, express train, motor-car or fast steamer. A questionnaire is being circulated amongst commercialassociations throughout the country, with a view to securing more extensive use of aeroplanes in the postal service.
