Airships past and present, together with chapters on the use of balloons in connection with meteorology, photography and the carrier pigeon . Dayton, Ohio, and having enjoyeda good technical education and started a successful bicyclefactory, they turned their attention to the problem of had the help of Chanute, and followed Lilienthals planof mastering the art of floating before trying the effects of amotor. With a wind blowing at the rate of 26 ft. a second,they were able with their apparatus to maintain themselves fora while in the air. The experiments were carried out on thedunes along the shore of the Atlantic, where a steady wind blowsthe whole year round. FLYING MACHINES. Ill They first directed their attention to three points : (1) whetherit is better to let the driver stand or lie down; (2) whetherstability is better ensured by special steering devices or byshifting the position of the centre of gravity; and (3) whateffect is produced by a rudder placed at the front of the experiments were always carried out in the same order, andthe machines were first tested like kites at the end of a Fig. 64.—Aeroplane in flight.(From the Leipziger Illustrierte Zeitung.) After any necessary changes had been made and a certainmodicum of stability seemed assured, one of the brothers laidhimself at full length in the machine. The work then continuedin the same keen and determined way ; neither the expected northe unexpected was sufficient to upset their mental form of the aeroplane was almost exactly the same as thatof Chanute and Herring. Two surfaces of the nature of sailswere arranged, the one above the other. At first they wereslightly concave; but this was abandoned in favour of flat 112 AIBSHIPS PAST AND PKESENT. surfaces. The driver lies at full length on the lower sail in aspace arranged for this purpose. In front of him is the ruddercontrolling the elevation. The vertical rudder for directing thehorizontal motion is behin
