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!"
