Four men came bounding over the bulwarks. "Captain!" they called; "where are you, captain?"
"Here!" yelled the captain. "Make prisoners of these two fellows, Katz and Clancy. Katz is on the deck, there, and Clancy—"
Clancy was just going over the side and into the water, so it was impossible to make a prisoner of him. He took the valuable satchel along.
"Get back into that boat, two of you," bellowed Hogan, "and snake that red-headed streak of lightning out of the water and back aboard the Sylvia! Look alive, now! A hundred-dollar bonus to the man who captures Clancy and recovers the satchel he's got with him!"
Two of the men flung themselves into the boat and put off. The other two gave their first attention to Bob Katz, and bound him with the rope which was taken from the captain. So Katz, as it will be seen, was left in the hands of his enemies, thereby getting vastly more than he had bargained for.
Meanwhile, the motor wizard was swimming. He was perfectly at home in the water, and, even though he was handicapped with a game shoulder, he found no difficulty in keeping afloat with the satchel, and in spite of the weight of his wet clothes.
"Clancy!" called a voice across the water. "Where are you, Clancy?"
Two boats, at that moment, were searching for the motor wizard. One, of course, held enemies and was coming from the Sylvia, the other, carrying Hill and Burton, was approaching from the pier.
It was Hiram Hill who had hailed. Clancy knew, for he had recognized the voice.
"This way, Hiram!" the motor wizard cried.
