“Where?” demanded Jack, his eyes burning and his heart giving a violent thump.

“Right by the last cage.”

“The one that the black fox is in?”

“Yes.”

“By hookey, I do! It’s—it’s———”

“A man!”

“Holy smoke! What’ll we do now?”

“Get after him, of course. Come on!”

Clutching his rifle in his gloved hands Tom started forward, but before he could move another step he stopped short. From over by the black fox’s cage there came a shot and a blinding flash.

“He’s shooting!” cried Sandy in real alarm.
