A New Balloon.
Mr. Charles F. Ritchel, an American, has invented a balloon which can be raised or lowered at pleasure, without either throwing out ballast or loosing gas. The balloon consists of a horizontal cylinder with square ends, to which is attached a netting six. feet wide and as long as the balloon. Under this is a series of canvas shutters lapping over one another, and opened or closed by a screw propeller worked by hand. When the shutters are closed they offer resistance to the air, when open they allow the balloon to rise. The action of the propeller gives an upward or downward motion, according to the direction m which it is revolved.
