"Remember how we managed to align this thing? I wonder if it might not take another alignment to make it work as a relay."
"Could be," said Jim. "I'll try it. Christine, you work these screws at the same time we do, and make the current come out as low as we can."
They returned to their stations and began to work on the alignment screws. Jim came out first on the receiver. Christine was second on the transmitter, while Barney fumbled for a long time with the relay tube.
Then Christine called: "Fellows, my meter readings are climbing up again. Shall I diddle?"
"Wait a minute," said Barney. "That means I'm probably taking power out of that gadget you have in there. Leave 'em alone."
He fiddled a bit more, and then Jim called: "Whoa, Nellie. Someone just lost me a millimeter. She wound up on the far end."
"Hm-m-m," said Barney, "so we're relaying."
"Go ahead," said Jim. "I've got a ten-ampere meter on here now."
Barney adjusted his screws some more.
"Wait a minute," said Jim. "I'm going to shunt this meter up to a hundred amps."
