Kit chuckled.  Along with the continuous discovery of his own powers had come an ever-increasing disapproval of the two masters.  It was not so much irritation, which was always present, as disgust.  He had got his taste of the meat, and liked it; but they were teaching him how not to eat it.  Privily, he thanked God that he was not made as they.  He came to dislike them to a degree that bordered on hatred.  Their malingering bothered him less than their helpless inefficiency.  Somewhere in him, old Isaac Bellew and all the rest of the hardy Bellews were making good.

“Shorty,” he said one day, in the usual delay of getting started, “I could almost fetch them a rap over the head with an oar and bury them in the river.”

“Same here,” Shorty agreed.  “They’re not meat-eaters.  They’re fish-eaters, and they sure stink.”

They came to the rapids; first, the Box Canyon, and, several miles below, the White Horse.  The Box Canyon was adequately named.  It was a box, a trap.  Once in it, the only way out was through.  On either side arose perpendicular walls of rock.  The river narrowed to a fraction of its width and roared through this gloomy passage in a madness of motion that heaped the water in the center into a ridge fully eight feet higher than at the rocky sides.  This ridge, in turn, was crested with stiff, upstanding waves that curled over yet remained each in its unvarying place.  The Canyon was well feared, for it had collected its toll of dead from the passing goldrushers.

Tying to the bank above, where lay a score of other anxious boats, Kit and his companions went ahead on foot to investigate.  They crept to the brink and gazed down at the swirl of water.  Sprague drew back, shuddering.

“My God!” he exclaimed.  “A swimmer hasn’t a chance in that.”

Shorty touched Kit significantly with his elbow and said in an undertone: 

“Cold feet.  Dollars to doughnuts they don’t go through.”

Kit scarcely heard.  From the beginning of the boat trip he had been learning the stubbornness and inconceivable viciousness of the elements, and this glimpse of what was below him acted as a challenge.  “We’ve got to ride that ridge,” he said.  “If we get off it we’ll hit the walls.”

“And never know what hit us,” was Shorty’s verdict.  “Can you swim, Smoke?”

“I’d wish I couldn’t if anything went wrong in there.”

“That’s what I say,” a stranger, standing alongside and peering down into the Canyon, said mournfully.  “And I wish I were through it.”

“I wouldn’t sell my chance to go through,” Kit answered.

He spoke honestly, but it was with the idea of heartening the man.  He turned to go back to the boat.

“Are you going to tackle it?” the man asked.

Kit nodded.

“I wish I could get the courage to,” the other confessed.  “I’ve been here for hours.  The longer I look, the more afraid I am.  I am not a boatman, and I have with me only my nephew, who is a young boy, and my wife.  If you get through safely, will you run my boat through?”
