Part 24 (1/2)

Chapter XIV.--The Finding Of The Stone Chest.

”Help! help!”

Why he uttered the cry Bob could scarcely tell.

He did not imagine that any human beings were within sound of his voice.

Yet it is natural for a person in mortal peril to cry for a.s.sistance.

Luckily his cries were heard.

Captain Sumner was returning from the _Dart_, having hastily summoned Bok, Leeks, and the others.

Glancing in the direction, he saw the polar bear and then Bob.

He did not stop to think, but, taking hasty aim, fired.

Bok also discharged his weapon, and, hit twice in the neck, the beast staggered back.

Bob now saw his friends, and, running up the stream, joined them.

With so many against him the bear tried to flee, but a second bullet from the captain's gun finished him.

”Oh, how thankful I am that you have come,” cried Bob gratefully. ”I thought I was a goner.”

”Don't waste time here,” exclaimed Captain Sumner. ”These shots will alarm those people we left at the ice cave.”

”That is true,” said Bob. ”Come on--we must rescue my father!”

And he led the way, with the captain at his side.

It was a rough journey up the side of the hill again, and more than once they had to stop to catch their breath.

At the top a surprise awaited them.

The band of strange people had disappeared!

At first Bob could scarcely believe his eyes.

”Where are they?”

”Gone!”

”But to where? I can't see them anywhere.”

Captain Sumner shook his head.

A telescope was brought into play, but it did no good.

Captors and captive had alike gone, no one could tell where.
