“I give ye the word of a gentleman that he shan’t never trouble ye no more,” replied Jack significantly.

Mr. Mortimer hurried out of the cabin, slamming the door after him. As he sprung upon the deck of the flatboat he was met by the captain, who was impatiently awaiting his appearance.

“We are ready at last,” said the passenger, “and the sooner you get under way the better it will suit me.”

“Stand by the lines,” shouted the captain.

“Where’s that man?” continued Mr. Mortimer.

“He must be made of iron,” said the skipper, “for he has kept up that walk ever since we landed here this morning, and shows no sign of giving out.”

“There is nothing strange in that. He is working for money, and wants to be where he can see everything that is going on. Have you told him that he can not go down the river with us?”
