truck from the
way he looked. He was afraid to face dad."

"Well, it wasn't his fault," said Joe. "No man without a weapon is a
match for two armed rascals."

"Didn't he say what the robbers looked like?" insisted Jimmy. "He must
have known whether they were short or tall or fat or skinny."

"He said they were about medium height, both of them," returned Herb.
"He said they were both about the same build--rather thin, if anything.
But their faces were so well covered--the upper part by a mask and the
lower by bandana handkerchiefs--that he couldn't give any description of
them at all."

"I bet," Bob spoke up suddenly, "that whoever is at the head of that
rascally gang knows the danger of radio to him and his plans. That's why
his men are so careful to escape recognition."

The boys stared at him for a minute and then suddenly the full force of
what he intimated struck them.

At the same instant the name of the same man came into their minds--the
name of a man who used radio for the exchange of criminal codes, a man
who stuttered painfully.

"Cassey!" they said together, and Herb added, thoughtfully:

"I wonder!"

CHAPTER XV

OFF TO THE WOODS

For days the town hummed with the excitement that followed the daring
robbery of the truck belonging to Mr. Fennington, but as time passed and
there seemed little prospect of bringing the robbers to justice,
interest died down. But the radio boys never abated their resolve to do
all in their power to recover the stolen merchandise, although at that
time they were kept so busy in high school, preparing for a stiff
examination, that they had little time for anything else.

"It's getting so bad lately that I don't even get time to enjoy my
meals," grumbled Jimmy, one sunny spring afternoon. "Swinging an oar a
la Ben Hur would be just a little restful exercise after the way we've
been drilling the last week."

"Get out!" exclaimed Joe. "Why, you wouldn't last two hours in one of
those galleys, Doughnuts. They'd heave you over the side as excess
baggage once they got wise to you."

"After two hours of rowing in one of those old galleys, he'd be glad to
get heaved overboard, I'll bet," put in Herb, grinning. "I think Jimmy
would rather drown any day than work that hard."

"Huh! I don't see where you fellows get off to criticize," retorted the
harassed youth. "I never saw any of you win gold medals for hard and
earnest work."

"Lots of people deserve medals
