The man got off his horse to let him graze, and walked along till he got so far ahead of the horse that he had to sit down and wait for him.

Suddenly he found that he was on a quicksand.

His feet had sunk in the sand, and he could not get them out.

He threw himself down, and whistled for his horse, and shouted for help, but no one came.

He could hear some young people singing out on the river, but they could not hear him.
