Inflying, a bird does notpropel itself throughthe air, but glides for-ward by opposing theresistance of its wingsurface to the air. Itwill be recollected thatboth Lilienthal and Pil-cher adopted this the-ory in their respectivemachines, and were em-inently successful in. idson that the successful flying machine must be heavierthan the air, and that it must not be raised by meansof the balloon, but by a mechanical agency in whichthe vertical raising power should be greater than thedownward pull of gravity. To propel a machine up-ward against gravity, only a small fraction of the op-erators power is available to overcome the attractionof gravity, and the weight of the apparatus to generatesufficient power for this purpose is always more thanit can lift. In his machine the lifting power is greaterthan gravity, so that the apparatus can easily liftitself, the combination of the two forces supplying thenecessary forward motion to the machine. In design, the Davidson machine resembles a hugebird with its extended. The body of thebird constitutes the car, in which are placed the steamturbines for generating the necessary power to actu-ate the lifting appliances, placed at the extremitiesof each wing. These lifters, as they are called, re-semble r
