First probably for mails, and after this for passenger-carrying, will aeroplanes of the future be employed; and they will find a scientific use, too, in exploring remote corners of the earth, and in passing above forests which are now impenetrable. Small, fast machines, much cheaper than those of to-day, will be bought also for private use--many of them, as suggested by Fig. 105, having room for only one man within their hulls. Then there will be flying clubs; and to these, after their day’s work, will come a city’s toilers. Through the cheapening of craft, as time goes on, practically all members of the community will experience the joys of flight. Thus, say on a summer’s evening, the doors of the sheds will be pushed aside, and the machines wheeled out and overhauled; then, one by one, these small, fast-moving craft will rise into the air and dart here and there--circling, manœuvring, dipping, and diving. So, one after another, either as pilots or passengers, will the members of the club ascend; and before the sheds are closed and the aerodrome deserted, each and all will have soared in flight, and tasted that thrill and exultation which comes of a rush in a plane through the cool of the evening air. But to-day, if we try to grasp such a notion as this, our state of mind is very like that of our grandfathers had some prophet dared tell them the day would dawn when, seated comfortably at dinner in a car on wheels, men would be drawn by an engine at 60 miles an hour: and yet the man or woman who has not, say twenty years hence, made a journey through the air, will be in exactly the same position as one who, at the present time, has never been by train.
