"It's a lesson to keep a sharp lookout," thought the boy to himself. "In future we'll keep all bidarkas at long range unless they can give an account of themselves."

The boy went back to his work, but this time with a rifle beside him. He was still at his task when he heard voices.

"Cracky! It's those rascals coming back, I'll bet a doughnut," he exclaimed to himself excitedly.

With hands that shook a little, he picked up the rifle and prepared to give them a warm reception. As he was stepping out on deck, he collided with a figure just entering the engine-room door.

"Stop right where you are or I'll fire!" he cried out in a loud tone.

"What's the matter with you, Jack, are you crazy?" cried a voice that he instantly recognized as Tom's.

His relief was great, and as the hunting party, laden with three geese, some ducks and shore birds, came into the deck-house, explanations ensued. It appeared that the hunting party had been almost as much alarmed as Jack, for they had heard the report of his rifle and had hastened back at once without lingering at their sport.

Naturally Jack's tale of the occurrences during their absence aroused a good deal of indignation. Mr. Chillingworth, however, said he was not surprised. The Yukon Indians are great thieves, and it is necessary to be on constant watch against them. He was astonished, though, at Jack's story of the dart from the nogock.

"These Indians don't usually resort to anything like that," he said. "That old chief must be what the police in the Yukon country call a 'bad one.' I suppose he saw that only a boy opposed him and his men, and he intended to give you a good scare."
