"But remember I cannot test it for speed on this short and almost circular track. Right at the start, however, I see that something about the power-feed must be changed."
"What is that?" asked Mary, curiously.
"I have only had rigged here one trolley wire. There must be two attached alternately to the catenary cable. Such a form of twin conductor trolley will permit the collection of a heavy current through the twin contact of the pantagraph with the two trolley wires, and should a.s.sure a sparkless collection of the current at any speed. You noticed that when I took the sharper curves there was an aerial exhibition. I want to do away with the fireworks."
The fact that the Hercules 0001 was a going and apparently powerful draught engine satisfied most of the onlookers that Tom Swift was on the road to final and overwhelming success. The mechanics, indeed, saw no reason why the locomotive could not be run right out of the yard on the freight track and coupled to the first train going West. Of course, the Hercules 0001 could not be delivered to the Hendrickton & Pas Alos under its own power.
When the locomotive was run back into the shed and stood once more on the erection track, Tom confessed to Mary and Ned, while Mr. Damon and Mr. Swift were looking through the huge cab, that he was not at all pleased with the action of the machine.
"I have the best equipment of any electric locomotive on the rails today. I am sure of that," he said. "The Hercules Three-Oughts-One is not as long as those electric locomotives of the C. M. &. St. P. But that"s all right. I have built mine more compactly and, properly geared, it should have all the power of either the Baldwin-Westinghouse or the Jandel locomotive."
"Then, Tom dear, what is wrong?" cried Mary.
"Speed. That is what troubles me. Have I got anything like the speed I am aiming for?"
"Two miles a minute!" breathed Ned Newton. "Some speed, boy!"
"And must you have such great speed, Tom?" repeated Mary.
"That is in my contract. Not only that, but to be of much use to the H.
& P. A. this locomotive must have such speed--or mighty near it. Of course, under ordinary conditions, two miles a minute for a locomotive and train of heavy freights would burn up the track--maybe melt the f.l.a.n.g.es and throw everything out of gear."
"Why try for it, then?" demanded Mary.
"It is the power suggested by the possession of such speed that we want in the Hercules Three-Oughts-One. That two miles a minute is a fiction of the imagination, cannot be claimed. It is possible. It is humanly possible. It is coming."
"Then you must be the fellow to first accomplish it, Tom Swift," Ned declared.
"Of course, if anybody can do it, you can, Tom," agreed the girl complacently.
"Thanks--many, many thanks," laughed the young inventor. "I"d be able to harness the sun and stars, and put a surcingle around the moon if I came up to my friends" opinion of my ability.
"Nevertheless, two-miles-a-minute is my objective point, and I do not believe it is visionary. Consider the motor-cycle. Ninety miles an hour has long been possible with that, and some tests have shown a speed of over a hundred and ten. That is not far from my mark.
"Some Mallet locomotives of the oil-burning type have achieved from eighty-five to ninety-five miles an hour with a heavy load behind them.
They are very powerful machines. The Mogul mountain climbers are powerful, too, although they are not built for speed.
"The electric Goliaths built for the C. M. & St. P., and the Jandels, are both very speedy under certain conditions. The former has a maximum speed of sixty-five miles and the Jandel slightly faster."
"But that is only half what that Mr. Bartholomew demands of your invention, Tom!" Mary cried.
"That is a fact. I must reach twice sixty miles an hour, anyway, to meet his demand and gain that hundred thousand bonus. But I have the advantage of a knowledge of all that has been done before my time in the matter of electrical locomotive construction."
"The world do move," repeated Ned. "You believe that you have the edge on all the other inventors?"
"Along the line of this development--yes," said Tom. "I am taking up the work where former experimenters ended theirs. Why shouldn"t I find the right combination to bring about a two-miles-a-minute drive?"
"Oh, Tom!" cried Mary, with clasped hands, "I hope you do."
"I hope I do, too," said Tom, grimly. "At least, if trying will bring it, success is going to come my way."
Chapter XIV
Speed
More than four months had pa.s.sed since the contract had been signed, when Tom made his first yard-test of the Hercules 0001. For a month nothing had been seen or heard of Andy O"Malley, whose ident.i.ty as the spy, set by Montagne Lewis to cripple Tom"s attempt to help the Hendrickton & Pas Alos Railroad, had been determined beyond any doubt.
The private inquiry agent that Tom had engaged to find O"Malley had been unsuccessful in his work. The spy had disappeared from Shopton and the vicinity. Nevertheless, the inventor did not for a moment overlook the possibility that the enemy might again strike.
Every night the electric current was turned into the wires that capped the stockade of the Swift Construction Company enclosure. Koku beat a path around the enclosure at night, getting such short sleep as he seemed to need in the forenoon.
"Dat crazy cannibal," grumbled Rad, "got it in his haid dat he"s gwine to he"p Ma.s.sa Tom by walkin" out o" nights like he was dis here Western, de great sprinter, Ma lawsy me! Koku ain"t got brains enough to fill up a hic"ry nut sh.e.l.l. Dat he ain"t."
Nothing anybody else could do for Tom ever satisfied Rad. The colored man fully believed that he was the only person really necessary for Tom"s success and peace of mind. In fact, Rad thought that even Ned Newton"s duties as financial manager of the firm were scarcely of as much importance.
When he heard that Tom was going West, after a time, with the electric locomotive, to try it out on the tracks of the H. & P. A., Rad was quite sure that if he did not go along, the test would not come out right.
"O" course yo"ll need me, Ma.s.sa Tom," he said, confidently. "Couldn"t git along widout me nohow. Yo" knows, sir, I allus has to go "long wid yo" to fix things."
"Don"t you think father will need you here, Rad?" Tom asked the faithful old fellow. "You"re getting old--"
"Me gittin" old?" cried, the colored man. "Huh! Yo" don"t know "bout dis here chile. I don"t purpose ever to git old. I been gray-haided since befo" yo" was born; but I ain"t old yit!"
Mr. Damon chanced to be present at this conversation, and he was highly amused, yet somewhat impressed, too, by the colored man"s statement.
"Bless my own antiquity!" he exclaimed. "I agree with Rad, Tom. It"s us old fellows who know what to do when an emergency of any kind arises. Experience teaches more than inspiration."
"Oh," said Tom, laughing, "I do not deny the value of old friends at any stage of the game."
"Bless my roving nature! I am glad to hear you say that. For I tell you right now, Tom, I want to be out there when you make your final test of the locomotive."
"Do you mean that you will go West when I take out the Hercules Three-Oughts-One?" cried Tom.
"It"s just what I want to do. Bless my traveling bag, Tom! I mean to be present at your final triumph."
"What will happen to your buff Orpingtons while you are gone?" asked the young inventor, gravely.
"I have got my servant trained to look after those chickens," declared Mr. Damon. "And this invention of yours is really more important than even my buff Orpingtons."
"Just the same," remarked Tom to his eccentric friend, when Rad had left the room. "I"ve got to fix it so that Eradicate stays at home with father. He doesn"t really know how old and broken he is--poor fellow."
"His heart is green, Tom. That"s what is the matter with Rad."
"He is a loyal old fellow. But I shall take Koku with me, not Rad," and the young inventor spoke decidedly. "And that is going to trouble poor Rad a lot."
