"He's ribbing me about those relays," laughed Larry, while Jimmy was saying: "Y'smell that smell? That was my pride and joy."

"Tell me," asked McBride, "what does he do?"

"Who, Steve? Oh he's just the bird that wanted the things done that resulted in this mess. He's primarily responsible."

"Hm-m-m. That puts the fix on the whole thing," said McBride. "Well, fellow, you've heard about Enid. I've got to get home. If we can fake up something so that the Haywire Queen will cut loose with a couple of hundred feet per for long enough to get me to Station 1, I'll see that your ruined equipment is replaced so that you can make a safe landing. Say! How come you do not carry a spare alphatron?"

"Why doesn't man come with two hearts?" asked Jimmy. "That's because they're usually dependable. No one ever tried to run two brains off of one heart—that's why one heart stands up pretty well. I can imagine the trouble that would result if two involuntary control centers were running the same heart—it would be something like what happened when the mech-grav made the E-grav cut in—something would blow a fuse."

They laughed, and then Hammond explained about the program. "Right away quick we'll try the mech-grav along with the mag-grav. That sounds like our best bet for something that works. Also breach the lifeship and sabotage the little alphatron for the mech-grav. Might as well have it down here where it's needed." In an aside to McBride, he added: "Is this like your place? No fuses, no safety devices, no spare equipment because some screwball is always filching something off of a bit of standard equipment to make an experimental set-up?"

"Anything but the running and operating gear of the Lens stations," said McBride, "is subject to change without notice. I've even seen a spare mech-grav generator used to counterbalance Jim Lear's teeter-totter. Jim's dad is on Station 3 and there isn't any kid of that size and age on Three. Did a good job, too, since Bob Lear fixed the mech-grav density control with a switch that urged the far end of the plank so that Jim was lifted and dropped at the right speed."

"Sort of expensive counterbalance, wasn't it?"

"I suppose so, but Bob said it was better than having to crank his son up and down by hand. Besides, we have lots of power out at the Lens." McBride paused. "Say. Do you run the Haywire Queen with this crew? Who's pilot?"

"Hannigan. But he got hurt when the works blew up. He ran us in all right, though any of us can take a trick at landing. But he's taking a rest cure to soothe his nerves; they got a scrambling from too much electricity."
