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 round up the spies. You know Milton says 'They also serve who only stand and wait.' If there aren't any reserves to stand and wait behind the lines, the men on the firing-line do not dare to push ahead. And besides, Roy, it is seldom that four boys play so important a part in great deeds as you four boys already have played."

"Four boys and a man," corrected Henry. "Without you we could never have gotten anywhere," and Henry looked affectionately at his captain.

"Oh! Yes, I had a part in it," agreed the captain, "but it was only a part."

"But you read the ciphers," protested Henry. "If you hadn't done that, we could not have made any headway at all."

"And who caught the messages for me to decipher? The reason we have gotten along so well is because we work together so perfectly. I want to thank you boys for being so faithful. I've given you many hard tasks to do."

"After our experiences at Camp Brady," said Lew, "we couldn't do anything else than be faithful. We know by experience what happens when we don't do our duty."

"Then you are going to listen in during the remainder of the spy hunt," said Captain Hardy, with an affectionate smile, "just as faithfully as though your work weren't already done and the spice gone out of it. I know it will be dull and uninteresting, boys, but you've made such a fine record that I don't want you to fall down now. So be very careful—if only for my sake."
