at we have found
out here, so they gave the fellow back his money. But I am morally
certain that their man is the spy who carries the messages across the
border."

"Of course," cried Willie. "What else could he be--sneaking across the
boundary with three silver dollars."

Everybody laughed.

"It doesn't follow that he's a spy, just because he has three silver
dollars. He may be a smuggler, all right enough. But I believe the
smuggling is just a blind. If he were a genuine smuggler, he'd bring
more than three dollars' worth of stuff across."

"What have they done with his dollars now?" asked Roy eagerly.

"I don't know, Roy. The Chief got into instant touch with his men at
El Paso as soon as I showed him the dollar Henry got. But I left
before I knew what the outcome was. However, I have no doubt they will
find that the dollars are what we suspect them to be."

"Gee!" said Willie. "To think that the wireless patrol found out about
those dollars!"

"I guess the secret service knows by this time that boys are worth
something," smiled Roy. "Before we get through, they may think so even
more."

"You're certainly not increasing in modesty," laughed their leader.

"Well, I don't care," said Roy hotly. "It makes me tired. Everybody
says, 'Oh! They're only boys.' Of course we're only boys, but look at
what we've done. Why, the wireless patrol has got the best set of
fellows----"

But Roy's protest was smothered in a burst of laughter from his fellows.

"Well, I'm glad you feel so good over what we've been fortunate enough
to accomplish," said Captain Hardy, "for I fear there will be no more
excitement for you. The Chief says his men now have the spy business
well in hand, and that all he wants of us from now on is merely to stay
here and catch their messages until he is ready to make his raid."

"Just what I was saying," burst out Roy indignantly. "They won't let
us in on their raid because 'we're only boys.' But who was it caught
the dynamiters, if it wasn't 'just boys'? The men couldn't do it.
They tried twice and failed. Gee! It makes me tired."

"Never mind, Roy," said Captain Hardy smiling. "Even if we don't have
any further taste of excitement, we can always remember that we had a
big part in catching these spies--for they're going to be caught, sure.
And you mustn't forget that if we stay here and do well the part
assigned to us, we are helping just as much as the men who actually
