The little man appeared again, hefting a ponderous automatic. 'Who do we have to pop off?' he asked amiably.
Ann shivered. 'Bloodthirsty, isn't he?'
'They bred us that way in South America. Is it a riot, or what?'
'No, none of them. We're going to blow up World Research.'
'Splendid! I'd often thought of how elegant it would be to do that, if only some way could be figured out. Where's the machinery ye spoke of? I presume that is what you toss the bombs with.'
'In our apartment. Only it isn't bombs; it makes the most powerful explosive look like a slingshot in comparison.' They walked back to Train's flat and Ann pointed out Independent Fourteen.
'That's the junk,' she said simply.
'It's a powerful-looking bit of machinery. But what does it do?'
Ann told him briefly.
'No!' he cried. 'If it were as big as the Research Building it couldn't do that!'
'Calling us liars, mister?'
'Not a bit of it. All right. It does what you say it will—I hope. What's the campaign?'
'We march on the Syndicate Building, pushing Independent Fourteen before us. It's got wheels, you notice. The thing is nicely adjusted—it'll function on any violent shock as well as the hand controls; they know that, so they won't make any attempt to blow it up. In fact they know all about it, but I don't think they quite realize just how good it is.
Otherwise they'd talk differently.
'I'd better show you how to handle it. All you have to know about is this switchboard. The button here indicates radiation. The power will spread in all directions except in that of the operator and directly behind him. This other button is direction. That aims the influence of the machine in a fairly tight beam. Its action is invisible, but it's controlled by this pointer. And the results are soon apparent.'
'And what could be the meaning of these cryptic signs?' asked Hogan, indicating a long vertical list of symbols running parallel to the slot of an indicator needle.
'They are the chemical names of the elements.'
'I seem to remember,' remarked Hogan, knitting his brows.
'Got everything straight? Radiant, director, pointer, and elements?'
'Yes. We can go in my car, I suppose.'
They eased the ponderous machine safely down the flight of stairs, then into Hogan's car. Suddenly there boomed from Train's frequency inductor the voice of Hartly. 'Train!' it said. 'Listening,' the scientist snapped back.
'This is your last warning. I have a man across the street from you. He says that you've loaded Independent Fourteen into a car. You seem to think I intend to back down on my promise to release the fungus.'
'Not at all.' replied Barney cheerfully, 'not at all. On the contrary, I am convinced that you'll not hesitate to pour the stuff out of your window as soon as we come in sight. In fact, I'm counting on it, Hartly. Don't disappoint me, please.'
'Then remember, Train, nothing …nothing …can stop the fungus. As you say, one false move nearer my building, and I release the culture.'
'The false move is made, Hardy,' said Train, with steel in his voice. 'In case your man hasn't told you, the car has started. We are on our way.'
He snapped off the transmitter.
'What was that all about?' asked Hogan, his eyes on the road.
'Just Hartly. He thinks he has a final stymie to work on me. Plans to release a kind of mold that eats away all organic matter. Fire cannot destroy or injure it, nor can chemicals. Once he releases it, it'll spread through the world, attacking all live wood, grass, and animal life.'
'Yeah? What are you going to do about it?'
'Can't you guess? Hartly still doesn't realize that any power of his is just a joke so long as Independent Fourteen is in my hands. Pull up!'
The car skidded to a halt before the building that housed World Research. 'Take it out tenderly, husband mine,' said Ann. 'It means a lot to me.'
There was a rattling from the pocket wherein Train had thrust his frequency inductor. He took it out, held it to his ear.
Hartly's voice was dry by now. 'The bluff's never been pushed this far by any man, Train. This is your last chance. I'm looking down at you, and I have the fungus in my hand. Train, I'm ready to drop this bottle.'
'Are you, now?' The scientist's voice bespoke amusement. 'And what am I supposed to do about it?'
'Abandon your machine and walk into the building. I'll see that you are taken care of rightly. You'll not regret it if you choose to compromise; you will if you do not.'
Train laughed. 'For once, Hartly, I'm holding every ace in the deck.
Drop your little toy and see how useless it is to you.'
There was a long, tense pause. Hogan and Ann watched, but could see nothing. Train swiftly manipulated the little instruments on the control board. There was a little tinkle in the street near them.
'There, Barney, there!' Ann screamed, pointing a trembling finger at a scarcely visible splotch of green. Train swung the pointer of the machine on it even as it exploded upward into a bomb of poisonous vegetation that rustled foully as it spread serpentine arms outward and up.
Train slammed down the button that flung the machine into action, swept the pointer right and left as the tubes sputtered angrily.
'Glory!' muttered Hogan. The fungus had suddenly been arrested and now stood etched in silvery metal.
'Free metallic magnesium,' said Train. 'It works on a large scale and with one hundred percent efficiency.'
'Elements transmuted at will,' breathed Ann. 'And nothing went wrong!'
'And the machine will do—that—to anything?' demanded Hogan. 'It has the Midas touch.'
'That it has,' agreed the scientist, swinging the needle and shifting the slide. 'And, unless I'm mistaken, those men mean us harm.'
He swung the pointer against a squad of uniformed militia that were running from the huge doors of the building. The button went down, and the police went transparent, then gaseous. They vanished in puffs of vapor that sought the nearest solid.
'Fluorine,' said Train quietly. 'Those poor devils are just so much salt on the street and portico.'
'Let's go in,' said Ann. They walked into the lobby, treading carefully around the white crusts on the pavement.
'Easy, Hogan,' warned Train as they pushed Independent Fourteen into an elevator under the eyes of the horrified attendant. 'Take us to the Hartly floor,' he snapped at the latter, 'and no harm will come to you. Otherwise …' He drew a sinister finger across his throat.
The doors of the elevator rolled open and they carefully pushed the machine before them. 'Come out, Hartly,' called Ann at the bronze doors to the inner office.
'Come in and get me,' sounded from the frequency inductor in her hand. Resolutely they swung open the doors and marched in. Hartly was alone behind the desk. Quietly he lifted his hands, displayed two heavy pistols.
'I haven't been too busy managing my affairs to learn how to use these,'
he remarked. 'Stand away from that machine.'
Train tensed himself to leap, flinging Fourteen into operation, but Ann touched his arm and he relaxed, stepped aside with her and Hogan.
Hartly strode over and glanced at the machine. He set the slide absently. 'How does it work?' he asked.
'Red end of the pointer directs the beam. Slide determines the element required. Button on the left starts the operation.'
'The red end?' asked Hartly smiling. 'You would say that. I'll try the black end first.' He aimed the black end at the little group of three, thus bringing the red end squarely on himself.
'This button—' he began, pressing a thumb on it. But his words were cut short. A wild glare suffused his face as he brought up one of the pistols, but it fell from his hand, exploding as it hit the floor. He tried to speak, but a
