"All good then. Now I want to get to that atomic thing. We can let that slide for a little bit--I'll answer it." The telephone had rung noisily. "Kendall Labs--Kendall speaking." "This is Superintendent Foster, of the New York Power, Mr. Kendall. We have some trouble just now that we think your operations may be responsible for. The sub-station at North Beaumont blew all the fuses, and threw the breakers at the main station. The men out there said the transformers began howling--" "Right you are--I'm afraid I did do that. I had no idea that it would reach so far. How far is that from my place here?" "It's about a thousand yards, according to the survey maps." "Thanks--and I'll be careful about it. Any damage, I am responsible for? All okay?" "Yes, sir, Mr. Kendall." Kendall hung up. "We stirred up a lot more dust than we expected, Devin. Now let's start seeing if we can keep track of it. Douglass, how did your readings show?" "I took them at the ten stations, and here they are. The stations are two feet apart." "H-m-m--.5--.55--.6--.7--20--198--5950--6010--6012--5920. Very, very nice--only the darned thing's got an arm as long as the law. Your readings were about .2, Devin?" "That's right." "Then these little readings are just leakage. What's our normal intensity here?" "About .19. Just a very small fraction less than the readings." "Perfect--we have what amounts to a hollow shell of magnetic force--we can move inside, and you can move outside--far enough. But you can't get a conductor or a magnetic field through it." He put the readings on the bench, and looked at the apparatus across the room. "Now I want to start right on that other. Douglass, you move that magnetostat apparatus out of the way, and leave just the 'can-opener' of ours--the projector. I'm pretty sure that's what does the deed. Devin, see if you can hunt up some electrostatic voltmeters with a range in the neighborhood of--I think it'll be about eighty thousand." * * * * * Rapidly, Douglass was dismounting the apparatus, as Devin started for the stock room. Kendall started making some new connections, reconnecting the apparatus they had intended using on the "atomic engine," largely high-capacity resistances. He seemed to perform this work mechanically, his mind definitely on something else. Suddenly he stopped, and looked carefully into the receiver of the machine. The metal in it was silvery, liquid, and here and there a floating crystal of the dull red metal. Slowly a smile spread across his face. He turned to Douglass. "Douglass--ah, you're through. Get on the trail of MacBride, and get him and his crew to work making half a dozen smaller things like this. Tell 'em they can leave off the tungsten shield. I want different metals in the receiver of each. Use--hmmm--sodium--copper--magnesium--aluminium, iron and chromium. Got it?" "Yes, sir." He left, just as Devin returned with a large electrostatic voltmeter.
