At first the actions of the boys attracted no attention. Then there was a stir on the rear deck of the craft.
"Somebody in a rowboat, calling to you," remarked the captain of the schooner, to Josiah Crabtree.
"To me?" exclaimed the former teacher, in surprise. "I will see about this."
He hurried to the stern of the schooner. The rowboat with the Rovers had now come quite close. Josiah Crabtree gave a start.
"Can it be possible?" he gasped.
"What is it?" asked Jesse Pelter, who had stepped up.
"Those young men in yonder boat! Unless I am mistaken they are Anderson Rover's sons!"
"Is it possible!" ejaculated the broker. "Oh, there must be some mistake."
"No, no! I know them well! And see, they are motioning to us! They want us to stop!"
"They must have seen and followed us!" said the broker, and his manner showed his sudden fear.
