“We’ll take this boy along and drop him off at Fort Chipewyan,” said Curlie, turning to D’Arcy Arden.

The boy beamed his gratitude.

A few moments later the motor thundered and they were away.

When the party had in this manner been reduced to three, Johnny, Sandy and the hunchback bowman, Sandy exclaimed:

“Now, son! Lead me to this enchanted cave!”

An enchanted cave it proved to be. “It’s radium! Richest find ever made!” the prospector exclaimed the moment his eyes rested upon its walls. “Must be phosphorus and zinc blended with it in a peculiar manner. But it is rich in radium. I would stake my life on it.”

Just as they were preparing to leave the cave, they caught the sound of some one shouting. On reaching the exit they found Scott Ramsey waiting outside.

“You left no word,” he accused Sandy.

“The dog came with an emergency call. I could but answer,” Sandy rumbled.

“So you’re all safe!” Scott seemed relieved.
