He and Billy walked around and followed the beat which they had taken it upon themselves to cover. Everything was being conducted with military exactness. They had not forgotten the methods of the two rival armies in the mock battle, when they had served as signal corps operators, nor the example of the Naval Reserves, nor the work of the Life Savers.

When the two reached one end of their beat, they waited until another pair of khaki-clad figures approached, and then the secret countersign was passed between them in whispers. After that Hugh and Billy walked to the other end of their beat, and there rubbed up against another couple of scouts.

Ten o’clock came, and as yet all was well. Some of the boys began to weary of this unusual exertion. They had had a warm day and a most strenuous one as well. It did not seem surprising, then, that they should find themselves yawning at a terrific rate, and beginning to wish that something would happen, or else that Hugh would order them home.

This sort of thing was going on all over the section where Hugh had figured it was most likely the prank-loving vandals would start their work, if they ventured to do anything at all. The score and a half of scouts had been placed in such manner as to cover quite a large space. If Lige and his followers managed to slip inside the lines and cut up any tricks, they would have to be mighty crafty about it, for every scout was supposed to be constantly on the alert, watching right and left for suspicious conditions.

“Looks as if it might have been a case of bluff, doesn’t it, Hugh?” Billy said, when another half hour had crept past. Sounds from downtown were dying out as people went home, believing that there would not be any excitement, after all.

“It’s a little too early to settle that question, I’m afraid, Billy,” replied the assistant scout master. “If they meant to do anything, you wouldn’t expect them to start in until as late as this, anyway. We’ll try to hold out till midnight, and then if nothing starts, why I suppose we’ll have to go home and take chances.”

“Whee, an hour and a half yet, that means!” said Billy with a big sigh, as the church clock rang the half hour. He was hardly able to drag one fat leg after the other such was his utter weariness, but being the possessor of a stubborn spirit, Billy would not confess that he felt anything but “chipper.”

“Something may happen before then to change our plans,” Hugh told him. “If we managed to make a capture, I think you’d brighten up.”

“Just try me,” replied Billy, endeavoring to look as though he were not half dead for sleep; for Billy’s two great weaknesses were a love for lying in bed mornings, and a dislike to leaving the dinner table so long as anything to eat remained in sight.

“When the Chief came around just a little while back to see how we were getting on, he said he did not expect to have any trouble to-night,” Hugh continued. “That fierce proclamation from the mayor seems to have convinced him that the evildoers will all take to hiding. But we know different. Fellows like Lige Corbley and their crowd think very little of the mayor’s backbone. You see, about every one of them has a father or uncle who can exercise his ‘pull’ with the authorities, and they rely on that to get them off in case of trouble.”
