"It's my father!"

Chapter XIII.—The Big Polar Bear.

"Your father!" cried Captain Sumner.

"Yes, my father," repeated Bob, in high excitement. "What shall we do?"

He felt like rushing forward, but the captain restrained him.

"We can do nothing against such a force of men," he said. "Wait—or—"
He hesitated.

"What?"

"You or I might go back to the Dart for help. Every man on board can come heavily armed. When these people see our number they may be willing to talk reasonably to us."

"That's so, but I hate to leave," returned Bob. "They may do some harm to my father in the meantime."

"Then I will go, Bob. But mind, keep shady, unless they do something very bad."
