“Looks so we were in for it,” said Plum, after they had been left by themselves for an hour or more.

“They don’t stop to consider that. It is my opinion they would dare to do anything but meet an equal number of the enemy. It looks bad for us, Plum.”

“I wonder if we can’t dig out of here somehow? These walls don’t seem so awful thick.”

“Of course we must try and get out of this. The first thing to do will be to free our limbs. Can you loosen your bonds any?”

For the next ten minutes the boys were busy trying to free their hands from the ligatures which had been fastened in no uncertain way.
