«It’s a farce, Von Holtz,» he said dryly, «this pretending you’ll run away. You’re here spying now, for Jacaro. Of course. And you don’t dare harm either of us until you find out from me what you can’t work out for yourself, and know I have done. How much is Jacaro going to pay you for the secret of the catapult, Von Holtz?»
Von Holtz snarled. Smithers moved toward him, his hands closing and unclosing. Von Holtz went gray with terror.
«Talk!» said Smithers.
«A-a million dollars,» said Von Holtz, cringing away from the brawny red-headed man.
«It would be interesting to know what use it would be to him,» said Tommy dryly. «But to earn that million you have to learn what we know. And to learn that, you have to help us do it again, on the scale we want. You won’t run away. So I shan’t bother to lock you up hereafter. Jacaro’s men come and talk to you at night, don’t they?»
Von Holtz cringed again. It was an admission.
«I don’t want to have to kill any of them,» said Tommy pleasantly, «and we’ll all be classed as mad if this thing gets Out. So you go and talk to them in the lane when you want to, Von Holtz. But if any of them come near the laboratory, Smithers and I will kill them, and if Smithers is hurt I’ll kill you; and I don’t imagine Jacaro wants that, because he expects you to build another catapult for him. But I warn you, if I find another gun on you I’ll thrash you.»
Von Holtz’s pallor changed subtly from the pallor of fear to the awful lividness of rage.
«You-Gott! You dare threaten-» He choked upon his own fury.
«I do,» said Tommy. «And I’ll carry out the threat.»
Smithers moved forward once more.
«Mr. Von Holtz,» he said in a very terrible steadiness, «I aim to kill you some time. I ain’t done it yet because Mr. Reames says he needs you a while. But I know you got Miss Evelyn marooned off in them fern-woods on purpose! And-God knows she wouldn’t ever look at me, but-I aim to kill you some time!»
His eyes were flames. His hands closed and unclosed horribly. Von Holtz gaped at him, shocked out of his fury into fear again. He went unsteadily back to his lean-to. And Smithers went back to the dimensoscope. It was his turn to watch that other world for signs of Denham and Evelyn, and for any sign of danger to them.
Tommy adjusted the screen before the~ bench on which he was working, so Von Holtz could not see his task, and went back to work. It was a rather intricate task he had undertaken, and before the events of the past few days he would have said it was insane. But now he was taking it quite casually.
Presently he said, «Smithers.»
Smithers did not look away from the brass tube.
«Yeah?»
«You’re thinking more about Miss Denham than her father.»
Smithers did not reply for a moment. Then he said, «Well? What if I am?»
«I am, too,» said Tommy quietly. «I’ve never spoken to her, and I daresay she’s never even heard of me, and she certainly has never seen me, but-»
Smithers said with a vast calmness, «She’ll never look at me, Mr. Reames. I know it. She talks to me, an’ laughs with me, but she’s never sure-’nough looked at me. An’ she never will. But I got the right to love her.»
Tommy nodded very gravely.
«Yes. You have. So have I. And so, when that globe comes, we both get into it with what arms and ammunition we can pack in, and go where she is, to help her. I intended to have you work the switch and send me off. But you can come, too.»
Smithers was silent. But he took his eyes from the dimensoscope eyepiece and regarded Tommy soberly. Then he nodded and turned back. And it was a compact between the two men that they should serve Evelyn, without any rivalry at all.
Tommy went on with his work. The essential defect in the catapult Denham had designed was the fact that it practically had to be rebuilt after each use. And, moreover, the metallic ammonium was so fugitive a substance that it was hard to keep. Once it had been strained by working, it gradually adverted to a gaseous state and was lost. And while he still tried to keep the little catapult in a condition for use, he was at no time sure that he could send a pair of automatics and ammunition through in a steel box at any moment that Denham came close enough to notice a burning smoke-fuse attached.
But he was working on another form of catapult entirely, now. In this case he was using hollow magnets placed at known angles to each other. And they were so designed that each one tended to adjust its own hollow bore at right angles to the preceding one, and each one would take any moving, magnetic object and swing it through four successive right angles into the fifth dimension.
He fitted the first magnet on twin rods of malleable copper, which also would carry the current which energized the coil. He threaded the second upon the same twin supports. When the current was passed through the two of them, the magnetic field itself twisted the magnets, bending the copper supports and placing the magnets in their proper relative positions. A third magnet on the same pair of rods, and a repetition of the experiment, proved the accuracy of the idea. And since this device, like the dimensoscope, required only a forty-five-degree angle to our known dimensions, instead of a right angle as the other catapult did, Tommy was able to work with ordinary and durable materials. He fitted on the last two coils and turned on the current for his final experiment. And as he watched, the twin three-eighths-inch rods twisted and writhed in the grip of the intangible magnetic force. They bent, and quivered, and twisted… And suddenly there seemed to be a sort of inaudible snap, and one of the magnets hurt the eyes that looked at it, and only the edge of the last of the series was visible.
Tommy drew in his breath sharply.
«Now we try it,» he said tensely. «I was trying to work this as the mirrors of the dimensoscope were fitted. Let’s see.»
He took a long piece of soft-iron wire and fed it into the hollow of the first magnet. He saw it come out and bend stiffly to enter the hollow of the second. It required force to thrust it through. It went still more stiffly into the third magnet. It required nearly all his strength to thrust it on, and on… The end of it vanished. He pushed two feet or more of it beyond the last place where it was visible. It went into the magnet that hurt one’s eyes. After that it could not be seen.
Tommy’s voice was strained. «Swing the dimensoscope, Smithers,» he ordered. «See if you can see the wire. The end of it should be in the other world.»
It seemed an age, an eon, that Smithers searched. Then, «Move it,» he said.
Tommy obeyed.
«It’s there,» said Smithers evenly. «Two or three feet of it.»
Tommy drew a deep, swift breath of relief.
«All right!» he said crisply. «Now we can fling anything we need through there, when our globe arrives. We can build up a dump of supplies, all sent through just before we slide through in the globe.»
«Yeah,» said Smithers. «Uh-Mr. Reames. There’s a bunch of Ragged Men in sight, hauling something heavy behind them. I don’t know what it’s all about.»
Tommy went to the brass tube and stared through it. The tree-fern forest, drawing away in the distance. The vast and steaming morass. The glittering city, far, far in the distance.
And then a mob of the Ragged Men, hauling at some heavy thing. They were a long way off. Some of them came capering on ahead, and Tommy swung the dimensoscope about to see Denham and Evelyn dart for cover and vanish amid the tree-ferns. Denham was as ragged as the Ragged Men, by now, and Evelyn’s case was little better.
Frightened for them, Tommy swung the instrument about again. But they had not been seen. The leaders who ran gleefully on ahead were merely in haste. And they were followed more slowly by burly men and lean ones, whole men and limping men, who hauled frantically on long ropes of hide, dragging some heavy thing behind them. Tommy saw it only indistinctly as the filthy, nearly naked bodies moved. But it was an intricate device of a golden-colored metal, and it rested upon the crudest of possible carts. The wheels were sections of tree trunks, pierced for wooden axles. The cart itself was made of the most roughly hewed of timbers. And there were fifty or more of the Ragged Men who dragged it.
