With these words, and before any of the boys could stop him, he rose to his feet and sent a bullet from his ponderous revolver flying in the direction of the fleeing motor boat. It missed and hit the water near by, sending up a little fountain of spray.
Even at the distance they were the occupants of the Flying Fish could see the fear which this warlike move inspired in the bully and his companion. They threw themselves flat in their boat till only the hands of Bill, who was steering, were visible.
They need not have feared, however. The captain's hasty move brought down on his head Rob's wrath, though the young leader could not find it in his heart to be really angry with the old man who had been irritated past endurance by the bully's mocking defiance.
"Shiver my garboard strake," he exclaimed contritely, when Rob pointed out to him that he might have killed one of the occupants of the hydroplane, "shiver my garboard strake, lad, I saw red fer a minute just like I did that time the Chinese pirates boarded the Sarah Jane Butts in the Yellow River."
Although there was not much hope of catching the two, Rob stuck to the chase even when he realized the scouts were outdistanced, and in fact kept his attention so closely riveted on the other craft that when there came a sudden jar and jolt and the Flying Fish stopped with a grunt and a wheeze, he realized with a start that he had not been watching the treacherous channel and was once more fast on a sand bar.
With a last shout and a yell of defiance the bully and his companion, who had by now got over their fright, shot out on to the ocean and rapidly vanished.
"There goes our hope of catching those two crooks," cried Tubby angrily, while the engine of the Flying Fish was set at reverse. "It's all off now. They know that we have rescued Joe and they'll fly the coop for some other part of the country."
"I suppose they came down here to get their tent, not realizing we'd be here so soon," observed Andy, which indeed was the fact.
Fortunately the Flying Fish was not very hard aground and a little manipulation got her off into deep water once more.
"I guess those two chaps are almost in Hampton by this time and getting ready to leave town," observed Rob as the motor boat forged ahead, once more.
