At Edgewaroj, London, a De Havil land type D.H. 50, was flown with a new wing flap contrivance designed for tlierpurpose of reducing the speed for landing, or of carrying greater load' at some sacrifice of speed, says the “Daily Tefegraph.” The flaps are practically the- rear portion of the wings, hinged’ so that they can be depressed, and thus increasing the curve of the wing (as seen from the side). Normally, however, they are part of the natural curve*, or comber, of the wing. Similar flaps have been used on some of the Fairey aeroplanes for many years, but those are actuated by the pilot. In the Do HavilTand machine the action is automatic. As the speed of the machine is reduced, either by reducing power or by climbing, the flaps lower themselves. As the speed increases the hinged trailing rises against the action of a spring until it is a continuation or the normal wing curve. The machine flying during the trials did not stall until its air speed was less than 40 miles per hour. Having _ completely “stalled” its head slowly dipped, and the aeroplane picked up speed and resumed its normal flying attitude. Such a contrivance obviously may prove* or oreat value, enabling an aeroplane to drop into a small field. Against quite a eentle breeze its forward speed would be quite low. No cold is NAZOL-proof. And no and cold remedy is so economical as “NAZOL.” Eighteenpenoe buys oU flospfi—mors than a penny. That tickling, irritating cough can be promptly relieved by a few drops of “NAZOL” taken «R lump w
