"BE PREPARED"
"Paul!"
Jack's groping hand gripped the arm of his chum as he gave vent to this whisper.
"Yes," came the low reply close at hand, showing that Paul was awake, and alert.
"Did you hear it?" asked Jack, eagerly.
Bobolink was breathing heavily on his blankets, and it seemed as though he must have been the first one to get to sleep, after all his complaining about the hardness of his bed.
"Yes. Some one shook the door," answered the patrol leader, still whispering.
"That was what I thought. Shall I wake Bobolink and William?" asked Jack.
"Let me do it. If one of them gave a shout it would tell that we had a guard in here."
Paul, while saying this, started to crawl to where Number Three was enjoying a nap. He shook him gently, and when that failed to arouse Bobolink, the motion was increased.
