CHAPTER IV
"WHO ARE YOU?"
For a moment terror held the Racer boys motionless. The danger had come so suddenly that it deprived them of the power to think. Then came the reaction, and they were themselves once more.
"Quick! Throw your helm over! We can just make it!" yelled Frank.
"I'll attend to the sheet—you manage the tiller! Lively now!"
Andy needed no second command. He fairly threw himself at the helm, and with all his strength forced it hard over. The shortened sail rounded out with the pressure of the wind on it, and the Gull heeled over at dangerous angle. Under her keel came that ominous scraping sound that told of her passage over part of the Shark's Teeth.
"It's a submerged rock!" shouted Andy. "We may scrape over it!"
"Let's hope so!" murmured Frank, as he looked hastily down at the unconscious form of the strange lad. Then he gave all his attention to the rope that controlled the end of the swinging boom.
With the same suddenness that it had come upon them, the danger was past. The Gull slid into deep water, and the hearts of the boys beat in glad relief. Rapidly the craft paid off until she was well away from the ugly black points that could be seen, now and then, rearing up amid a smother of foam.
"Round about and beat for home!" yelled Frank. "Whoever this fellow is, he needs a doctor right away. I hope the wind holds out."
"Did you learn who he was?" asked Andy, as he gave his attention to putting the boat on the proper course.
