Airships past and present, together with chapters on the use of balloons in connection with meteorology, photography and the carrier pigeon . Fig. 132.—Basket of Count de la Vaulx balloon, showing the deviators. countrymen, named Herve, continued these experiments, andmade many successful expeditions. He used floating timbers inconjunction with sails, and succeeded in producing a deviationof about 70 degrees from the direction of the wind. Such BALLOONING AS A SPORT. 213 deviators consist of a frame into which a number of straightor bent pieces of wood are fitted, one behind the other, somewhatafter the fashion of a ladder. From the ends of this contrivance,ropes are taken to the balloon, by means of which the positionof the rungs can be altered so as to present a variable angle tothe course of the balloon. If the rungs are placed parallel tothe direction of flight, the balloon is subjected to a slight braking. Fig. 133.—Count de la Vaulx deviator in action. action, but the direction of its course is unaffected. If therungs are placed obliquely, the resistance, due to the water, isincreased, and the balloons course is deflected to that side onwhich the rope has been shortened. Count de la Vaulx has a balloon specially arranged for suchwater expeditions. He has an air-bag, which is not a necessityin the case of a free balloon; but it helps to preserve the shapeof the envelope, seeing that from some points of view his balloonmay be considered as being of the captive type. Many failures 214 AIKSHIPS PAST AND PEE SENT. have resulted, but a man of his energy is not easily beaten. Thecar of his balloon also contains a small motor for driving a pro-peller. His plans have been well laid, and he thinks there is nodanger in making a descent on the water. His water-anchorproduces such a braking action that in case of need theaccompanying steamship could easily overtake him. Othershave talked about cr
