"Here we are," he said a minute later. "We can't jump in, for there is no knowing where we are."
"Sure," from Donald. "Let's run along the wall."
This they did for about a hundred yards and then the wall ended abruptly against what appeared to be an abutment.
"We must act quickly," declared Donald. "They think you are Funston and won't hurt you. Keep up the deception. I'm going to swim for it. I'll have help here just as quick as I can. So long," and, throwing off his coat, he jumped into the water some twenty feet below.
CHAPTER XXVII.
THE ADMIRAL TO THE RESCUE.
When Donald struck the water he allowed himself to go clear to the bottom, as he wanted to find out just about how deep it was.
It was, as he had expected, about the depth of the water in the harbor and he made up his mind that he could not be far from some of the wharves that constitute the water front.
When he came to the surface, he struck out away from the wall, and by the light of the moon was soon able to see the vessels in the offing. He could also see that he was well north of the principal docks.
