He managed to get one hand comparatively free, so that he could move it about, but then he struck several hard knots, and could make no further progress. The conference seemed on the point of breaking up.

"One of you go for a big kettle to boil the tar in," ordered the leader, "and the rest of you dig up some feathers."

"I must get loose!" thought Tom desperately. "If they try to tar and feather me it will be a risky business. I've got to get loose! They may burn me severely!"

But, though he tried with all his strength, the ropes would not loosen another bit. He had one hand free, and that was all. The crowd was moving back toward him.

"My knife!" thought the captive quickly. "If I can reach that in my pocket I can cut the ropes! Once I get loose I'll fight the whole crowd!"

He managed to get his free hand into his pocket. His fingers touched something. It was not his knife, and, for a moment he felt a pang of disappointment. Then, as he realized what it was that he had grasped, a new idea came to him.

"This will be better than the knife!" he thought exultantly. The crowd of lads was now surrounding him, some distance from the fire, which burned in front of the captive.

"Sentence has been passed upon you," remarked the leader. "Prepare to meet thy doom! Get the materials, brothers!"

"One moment!" called Tom, for he wanted the crowd all present to witness what he was about to do. "I'll give you one chance to let me go peaceably. If you don't—"

"Well, what will you do?" demanded Andy sneeringly, as he pulled his mask further over his face. "I guess you won't do anything, Tom Swift."
