feet, or until the mixture was burned out. lie claims that it sails 

 along evenly, balancing perfectly, and that it may be steered by the 

 rudder. He prefers to fill the tank of the car with liquid air, on the 

 ground that it furnishes a maximum of stored power with light weight. 

 The air is exhausted and expanded through the nozzle at the top of 

 the pipe. Mr. Moore says: 



"The nozzle is placed at the top of the pipe, so that the push will 

 act directly on the string of the kite and not push the car out of 

 plumb, nor disturb the equilibrium of the machine. The kite is at- 

 tached to the machine by wires, which allows it to balance itself auto- 

 matically. Tin's property would be destroyed if it was attached rigidly

to the balance of the machine. The method of attaching the wires is 

 original and adds to the stability of the kite. The wheels are not 

 necessary for the locomotion of the machine in the air, but are nec- 

 essary in starting and alighting. In starting the machine, it is placed 

 in an open road, and when the power is applied it runs along on the 

 ground, gathering speed and giving the kite lifting power. When the 

 machine has attained the necessary speed, it will leave the ground 

 at a slight angle and continue in the air as long as it is forced ahead 

 at sufficient speed to sustain its weight on the aeroplane. In alighting, 

 the power should be shut off slowly until the machine settles to the 

 ground, where it would slow down and stop."
