That was the call of the Black Bear Patrol! He knew now that Jack was not far off. At the bottom of the tree he found the boy waiting for him!
"Say, but I've had a long wait!" Jack complained.
"Why didn't you signal before, then?" demanded Ned.
"Why, I thought you'd come right on, come on and meet me!"
"And you never knew I was here until I climbed the tree?"
"Of course not. How should I?"
"Well," Ned observed, "we'll know better next time. I presume I should have made a sign myself—the call of the pack, for instance."
"Of course," Jack replied. "Now," he went on, "do you know what's doing here?"
"I'm in quest of information," Ned grinned. "What have you found?"
"I've discovered that the Brady cabin is being watched!"
