In a light road-motor for carrying one or two persons on holiday trips or business rounds, the quality of adaptability of the source of power to the sudden demands due to differences of level in the road is not so absolutely essential as it is in traction engines designed for the transport of goods over ordinary roads.
Another locomotive whistled, and another train came through at top speed, and another, and another, train after train, train after train, till toward the last the trains were composed of passenger coaches, box-cars, flat-cars, dead engines, cabooses, mail-cars, wrecking appliances, and all the riff-raff of worn-out and abandoned rolling-stock that collects in the yards of great railways.
Owing to an accidental injury to the indicator, the power exerted by the engines of the Rattler in this trial could not be ascertained; but judging from the power exerted in other experiments with the same number of revolutions, it appears probable that the power actually exerted by the Rattler was about 300 horses.
The wind increased until it blew with almost the force of a cyclone, and the ship swayed fearfully. "Stop the engines!" cried the professor. "We had better drift than run the chances of hitting an iceberg if we should suddenly take a drop down to the ground." Washington, awakened from his sleep, turned off the power.
Everything she influenced seemed to recur as regularly as the motions of the great ruthless-looking engines that Gillian had seen at work at Belfast; the only loose cog being apparently her sister Adeline, who quietly took her own way, seldom came downstairs before eleven o'clock, went out and came in, made visits or received them, wrote letters, read and worked at her own sweet will.
These discoveries are of present interest chiefly to the scientific community; but they are important foundation-stones for more extensive exploration of outer space for the ultimate benefit of all mankind. Second, our military missile program, going forward so successfully, does not suffer from our present lack of very large rocket engines, which are so necessary in distant space exploration.
"Nothing yet," replied the doctor, who was breathing hard, but striving to keep himself professionally cool. "Not dangerously hurt?" whispered the captain; but in the terrible silence which had fallen his words were distinctly heard above the throbbing of the vibrating engines, which seemed to make the great vessel shudder at what had occurred. "I am not sure yet," said the doctor gravely.
But all these engines, brave hearts, and vigorous proceedings, appeared at first of no avail, for the greedy flames shot out their tongues, hissed through water and steam, and licked up the rich fuel with a deep continuous roar, as if they gloated over their unusually splendid banquet, and meant to enjoy it to the full, despite man's utmost efforts to oppose them.
After a while we got the engines and boilers and wires all done, and the lights in position, before the house was quite finished, and thought we would have an exhibit of the light. About eight o'clock in the evening we lit up, and it was very good. Mr. Vanderbilt and his wife and some of his daughters came in, and were there a few minutes when a fire occurred.
I believe that most all the best motor factories in England have learned to turn out good flying engines by now. It means a lot of difference to produce a machine that can do sixty miles an hour and one that can do two miles a minute.
