"I'll go up the river a bit further, if you say so," said the police officer in charge of the tug.
"Perhaps we had better run down first and make another search on our second trip," suggested Dick. "I shouldn't like them to get out into the Bay and give us the slip."
The tug was turned back, and a little later they reached the vicinity of the Battery once more. Then began another search up the river, from shore to shore, as before. But not a trace of the schooner could be found.
"Must have gone up the river," said the police official. "We'll try it for a way and see."
This they did, the police tug moving from side to side as before.
"This is the end of it, so far as we are concerned," said the officer in charge of the tug, at last. "We don't go up the river any further than this."
"All right then," answered Dick, much disheartened. "I guess the only thing for you to do is to put us ashore."
"Sorry we couldn't find that schooner. Of course, if you'll make a regular charge against these men we'll send word up the river to be on the lookout for them."
"We'll make the charge," answered Dick.
The steam tug turned in on the New York City side and the Rover boys went ashore.
