"Well, that's a more complicated undertaking," said Mr. Brandon.
"But there's no reason why you shouldn't, if you are willing to

"Uncle Sam has me working for him now as radio inspector, so I'm

"Mr. Brandon was with the aviation radio branch of the service during
the war," explained Dr. Dale, "and he has seen radio telephony develop
from almost nothing to what it is to-day."
"Yes, it was the war that speeded up the growth of radio," said Mr.
Brandon. "It revolutionized war in the air, and made it possible to
control the movements of airplanes in a way that had never, been
dreamed of before."
"You must have had some mighty interesting and exciting work,"
ventured Herb.
"All of that," admitted Dr. Dale's friend, with a smile. "Once our
whole station was wrecked by a bomb dropped on it from an enemy plane.
Luckily, we all had time to duck out before the bomb landed, but there
wasn't anything left of our fine station but a big hole in the ground
and bits of apparatus scattered around over the landscape.
