"Ulna, whele him go?" asked Wah Shin, stopping in the midst of loading the raft and looking about.
"He has gone down the river," said Sam, and his sad face told the Mongolian that something serious had happened.
"Him no gone gettee dlownded," gasped Wah Shin, and his eyes grew more oblique with alarm.
"Drownded!" cried Ike. "Why, Ulna kin swim like a whole flock of ducks in a mill pond."
"The river is very rough ahead," said Sam, "and after Ulna fell into the rapids he could not get back."
"An' whar did he go to?" asked Ike.
"Down the river."
"To de bottom?"
"I don't know."
"Golly!" exclaimed Ike, "if de ribber's as rough as dat, den we'd bettah stay whar we is."
