rebel movement itself only within the past few days. Thurston had asked
Tom and his companions to treat the information as confidential.

"I'd better get back to work," Tom decided after Bud and Ames had left
his office. Tom sat down at his drawing board and began to sketch out
some rough ideas for a vehicle to house the "brain energy" from space.

Tom wondered if the brain would be able to perform actions by itself,
given the proper mechanical output devices. Or would he have to help it
function via an electronic computer to digest incoming information or
stimuli and then to respond through servo controls?

The problem was so baffling and complex that Tom became completely
oblivious to the passage of time. He sketched out plan after plan, only
to crumple and discard each one.

Suddenly a disturbing thought jarred the young inventor out of his
concentration. Perhaps the Brungarian rebel scientists had now figured
out how to decode the radio messages from the Swifts' space friends!

If so, when the brain energy was launched toward earth, they might try
to divert it to their own receiving setup!
