Altas said: "Now your unit is operating at its correct level. But, son, you've missed one thing. It is far from efficient. Those two leads must be isolated from one another. Coupling from one to the other will lead to losses."

"Gosh," said Than, "I didn't know that."

"No, for some reason the books assume that the tower engineer has had considerable experience in the art. Take it from me, son, there are a lot of things that are not in the books. Now isolate those leads from one another and we'll go on."


"While you're thinking," said Jim, "I'm going to lockstitch these cables together. It'll make this thing less messy." Jim got a roll of twelve-cord from the cabinet and began to bind the many supply leads into a neat cable.

Barney watched until the job was finished, and then said: "Look, chum, let's try that electric-light trick again."

They swung the tube around until it was in the original position, and turned the juice on. Nothing happened.

Barney looked at Jim, and then reached out and pointed the big tube right at the electric light.

Nothing happened.
