Astounding Stories of Super-Science January 1931

“You see, Smithers, if a two-dimensioned creature wanted to adjust two right angles at right angles to each other, he’d have them laid flat, of course. And if he put a spring at the far ends of those right angles – they’d look like a T, put together – so that the cross-bar of that T was under tension, he’d have the equivalent of what I’m doing. To make a three-dimensioned figure, that imaginary man would have to bend one side of the cross-bar up. As if the two ends of it were under tension by a spring, and the spring would only be relieved of tension when that cross-bar was bent. But the vertical would be his time dimension, so he’d have to have something thin, or it couldn’t be bent. He’d need something ‘thin in time.’

“We have the same problem. But metallic ammonium is ‘thin in time.’ It’s so fugitive a substance that Denham is the only man ever to secure it. So we use these rings and adjust these springs to them so they’re under tension which will only be released when they’re all at right angles to each other. In our three dimensions that’s impossible, but we have a metal that can revolve in a fourth, and we reinforce their tendency to adjust themselves by starting them off with a jerk. We’ve got ’em flat. They’ll make a good stiff jerk when they try to adjust themselves. And the solenoid’s a bit eccentric – ”

“Shut up!” snapped Smithers suddenly.

He was facing the door, bristling. Von Holtz was in the act of coming in, with a beefy, broad-shouldered man with blue jowls. Tommy straightened up, thought swiftly, and then smiled grimly.

“Hullo, Von Holtz,” he said pleasantly. “We’ve just completed a model catapult. We’re all set to try it out. Watch!”

He set a little tin can beneath the peculiar device of copper-tubing rings. The can was wholly ordinary, made of thin sheet-iron plated with tin as are all the tin cans of commerce.

“You have the catapult remade?” gasped Von Holtz. “Wait! Wait! Let me look at it!”

For one instant, and one instant only, Tommy let him see. The massed set of concentric rings, each one of them parallel to all the others. It looked rather like a flat coil of tubing; certainly like no particularly obscure form of projector. But as Von Holtz’s weak eyes fastened avidly upon it, Tommy pressed the improvised electric switch. At once that would energize the solenoid and release all the tensed springs from their greater tension, for an attempt to reach a permanent equilibrium.

As Von Holtz and the blue-jowled man stared, the little tin can leaped upward into the tiny coil. The small copper rings twinkled one within the other as the springs operated. The tin can was wrenched this way and that, then for the fraction of a second hurt the eyes that gazed upon it – and it was gone! And then the little coil came spinning down to the work bench top from its broken bearings and the remaining copper rings spun aimlessly for a moment. But the third ring of whitish metal had vanished utterly, and so had the coiled-wire springs which Von Holtz had been unable to distinguish. And there was an overpowering smell of ammonia in the room.

Von Holtz flung himself upon the still-moving little instrument. He inspected it savagely, desperately. His full red lips drew back in a snarl.

“How did you do it?” he cried shrilly. “You must tell me! I – I – I will kill you if you do not tell me!”

The blue-jowled man was watching Von Holtz. Now his lips twisted disgustedly. He turned to Tommy and narrowed his eyes.

“Look here,” he rumbled. “This fool’s no good! I want the secret of that trick you did. What’s your price?”

“I’m not for sale,” said Tommy, smiling faintly.

The blue-jowled man regarded him with level eyes.

“My name’s Jacaro,” he said after an instant. “Maybe you’ve heard of me. I’m from Chicago.”

Tommy smiled more widely.

“To be sure,” he admitted. “You were the man who introduced machine-guns into gang warfare, weren’t you? Your gunmen lined up half a dozen of the Buddy Haines gang against a wall and wiped them out, I believe. What do you want this secret for?”

The level eyes narrowed. They looked suddenly deadly.

“That’s my business,” said Jacaro briefly. “You know who I am. And I want that trick y’did. I got my own reasons. I’ll pay for it. Plenty. You know I got plenty to pay, too. Or else – ”

“What?”

“Something’ll happen to you,” said Jacaro briefly. “I ain’t sayin” what. But it’s damn likely you’ll tell what I want to know before it’s finished. Name your price and be damn quick!”

Tommy took his hand out of his pocket. He had a gun in it.

“The only possible answer to that,” he said suavely, “is to tell you to go to hell. Get out! But Von Holtz stays here. He’d better!”

CHAPTER IV

Within half an hour after Jacaro’s leaving, Smithers was in the village, laying in a stock of supplies and sending telegrams that Tommy had written out for transmission. Tommy sat facing an ashen Von Holtz and told him pleasantly what would be done to him if he failed to make the metallic ammonium needed to repair the big solenoid. In an hour, Smithers was back, reporting that Jacaro was also sending telegrams but that he, Smithers, had stood over the telegraph operator until his own messages were transmitted. He brought back weapons, too – highly illegal things to have in New York State, where a citizen is only law-abiding when defenseless. And then four days of hectic, sleepless labor began.

On the first day one of Tommy’s friends drove in in answer to a telegram. It was Peter Dalzell, with men in uniform apparently festooned about his car. He announced that a placard warning passersby of smallpox within, had been added to the decorative signs upon the gate, and stared incredulously at the interior of the big brick barn. Tommy grinned at him and gave him plans and specifications of a light steel globe in which two men might be transported into the fifth dimension by a suitably operating device. Tommy had sat up all night drawing those plans. He told Dalzell just enough of what he was up against to enlist Dalzell’s enthusiastic cooperation without permitting him to doubt Tommy’s sanity. Dalzell had known Tommy as an amateur tennis player, but not as a scientist.

He marveled, refused to believe his eyes when he looked through the dimensoscope, and agreed that the whole thing had to be kept secret or the rescue expedition would be prevented from starting by the incarceration of both Tommy and Smithers in comfortable insane asylums. He feigned to admire Von Holtz, deathly white and nearly frantic with a corroding rage, and complimented Tommy on his taste for illegality. He even asked Von Holtz if he wanted to leave, and Von Holtz snarled insults at him. Von Holtz was beginning to work at the manufacture of metallic ammonium.

It was an electrolytic process, of course. Ordinarily, when – say – ammonium chloride is broken down by an electric current, ammonium is deposited at the cathode and instantly becomes a gas which dissolves in the water or bubbles up to the surface. With a mercury cathode, it is dissolved and becomes a metallic amalgam, which also breaks down into gas with much bubbling of the mercury. But Denham had worked out a way of delaying the breaking-down, which left him with a curiously white, spongy mass of metal which could be carefully melted down and cast, but not under any circumstances violently struck or strained.

Von Holtz was working at that. On the second day he delivered, snarling, a small ingot of the white metal. He was imprisoned in the lean-to-shed in which the electrolysis went on. But Tommy had more than a suspicion that he was in communication with Jacaro.

“Of course,” he said drily to Smithers, who had expressed his doubts. “Jacaro had somebody sneak up and talk to him through the walls, or maybe through a bored hole. While there’s a hope of finding out what he wants to know through Von Holtz, Jacaro won’t try anything. Not anything rough, anyhow. We mustn’t be bumped off while what we are doing is in our heads alone. We’re safe enough – for a while.”

Smithers grumbled.

“We need that ammonium,” said Tommy, “and I don’t know how to make it. I bluffed that I could, and in time I might, but it would need time and meanwhile Denham needs us. Dalzell is going to send a plane over today, with word of when we can expect our own globe. We’ll try to have the big catapult ready when it comes. And the plane will drop some extra supplies. I’ve ordered a sub-machine gun. Handy when we get over there in the tree-fern forests. Right now, though, we need to be watching…”

Because they were taking turns looking through the dimensoscope. For signs of Denham and Evelyn. And Tommy was finding himself thinking wholly unscientific thoughts about Evelyn, since a pretty girl in difficulties is of all possible things the one most likely to make a man romantic.

In the four days of their hardest working, he saw her three times. The globe was wrecked and ruined. Its glass was broken out and its interior ripped apart. It had been pillaged so exhaustively that there was no hope that whatever device had been included in its design, for its return, remained even repairably intact. That device had not worked, to be sure, but Tommy puzzled sometimes over the fact that he had seen no mechanical device of any sort in the plunder that had been brought out to be demolished. But he did not think of those things when he saw Evelyn.

The Ragged Men’s encampment was gone, but she and her father lingered furtively, still near the pillaged globe. The first day Tommy saw her, she was still blooming and alert. The second day she was paler. Her clothing was ripped and torn, as if by thorns. Denham had a great raw wound upon his forehead, and his coat was gone and half his shirt was in ribbons. Before Tommy’s eyes they killed a nameless small animal with the trunchionlike weapon Evelyn carried. And Denham carted it triumphantly off into the shelter of the tree-fern forest. But to Tommy that shelter began to appear extremely dubious.

That same afternoon some of the Ragged Men came suspiciously to the globe and inspected it, and then vented a gibbering rage upon it with blows and curses. They seemed half-mad, these men. But then, all the Ragged Men seemed a shade less than sane. Their hatred for the Golden City seemed the dominant emotion of their existence.

And when they had gone, Tommy saw Denham peering cautiously from behind a screening mass of fern. And Denham looked sick at heart. His eyes lifted suddenly to the heavens, and he stared off into the distance again, and then he regarded the heavens again with an expression that was at once of the utmost wistfulness and the uttermost of despair.

Tommy swung the dimensoscope about and searched the skies of that other world. He saw the flying machine, and it was a swallow-winged device that moved swiftly, and now soared and swooped in abrupt short circles almost overhead. Tommy could see its pilot, leaning out to gaze downward. He was no more than a hundred feet up, almost at the height of the tree-fern tops. And the pilot was moving too swiftly for Tommy to be able to focus accurately upon his face, but he could see him as a man, an indubitable man in no fashion distinguishable from the other men of this earth. He was scrutinizing the globe as well as he could without alighting.

He soared upward, suddenly, and his plane dwindled as it went toward the Golden City.

And then, inevitably, Tommy searched for the four Ragged Men who had inspected the globe a little while since. He saw them, capering horribly behind a screening of verdure. They did not shake their clenched fists at the flying machine. Instead, they seemed filled with a ghastly mirth. And suddenly they began to run frantically for the far distance, as if bearing news of infinite importance.

And when he looked back at Denham, it seemed to Tommy that he wrung his hands before he disappeared.

But that was the second day of the work upon our own world, and just before sunset there was a droning in the earthly sky above the laboratory, and Tommy ran out, and somebody shot at him from a patch of woodland a quarter of a mile away from the brick building. Isolated as Denham’s place was, the shot would go unnoticed. The bullet passed within a few feet of Tommy, but he paid no attention. It was one of Jacaro’s watchers, no doubt, but Jacaro did not want Tommy killed. So Tommy waited until the plane swooped low – almost to the level of the laboratory roof – and a thickly padded package thudded to the ground. He picked it up and darted back into the laboratory as other bullets came from the patch of woodland.

“Funny,” he said dryly to Smithers, inside the laboratory again; “they don’t dare kill me – yet – and Von Holtz doesn’t dare leave or refuse to do what I tell him to do; and yet they expect to lick us.”

Smithers growled. Tommy was unpacking the wrapped package. A grim, blued-steel thing came out of much padding. Boxes tumbled after it.

“Sub-machine gun,” said Tommy, “and ammunition. Jacaro and his little pals will try to get in here when they think we’ve got the big solenoid ready for use. They’ll try to get it before we can use it. This will attend to them.”

“An’ get us in jail,” said Smithers calmly, “for forty-’leven years.”

“No,” said Tommy, and grinned. “We’ll be in the fifth dimension. Our job is to fling through the catapult all the stuff we’ll need to make another catapult to fling us back again.”

“It can’t be done,” said Smithers flatly.

“Maybe not,” agreed Tommy, “especially since we ruin all our springs and one gymbal ring every time we use the thing. But I’ve got an idea. I’ll want five coils with hollow iron cores, and the whole works shaped like this, with two holes bored so…”
