"Don't excite him," murmured Prescott in an undertone. "The poor fellow isn't responsible for what he's doing. And I'd fight, too, if I thought any one was trying to seize me."

"I'm sorry if I had to hurt you," said Amos Garwood in a milder tone. "But I allow no one to come near me. I have too many enemies —-so many who are jealous of me that I can trust no one."

"He isn't really dangerous, poor fellow," whispered Prescott to his companions.

"No, though he has a habit of blowing up suddenly," muttered Reade. "He did the same thing once before, you'll remember, at the old water-works cottage."

"Are we going to try to catch the fellow this time?" Darrin whispered.

"Yes," nodded Dick. "We ought to, both for his father's sake and his own."

"What do you say, then, if we all three rush him?" pressed Darrin.

"It would be mean," Dick retorted in an undertone. "The poor fellow might be tempted to use his injured hand. And you can see how it's burned. I don't wonder. You saw how the flame of the explosion leaped all over that arm. It's a wonder it didn't set him afire."

"Are you boys going to leave me," inquired Garwood, "or are you going to remain and thus show me that you are truly of my enemies?"

"You slip back into the woods, Tom," whispered Dick. "See if you can find Greg and the other fellows. If you can, bring them up quickly."
