"You risked the lives of us all by running so close," cried Billy indignantly.
"Never attempt such a thing again," said Jack angrily, "or——"
"Or what, my nervous young friend?" taunted the elderly man.
"Yes," said the lad, with an unpleasant grin, "what will you do?"
"I shall feel sorely tempted to come on board your boat and give you the same sort of a thrashing I gave you the other day when I found you tormenting that poor dog," said Jack, referring to the incident Billy Raynor had already hinted at when he first recognized the occupants of the Speedaway.
"You'll never set foot on my boat," cried Donald Judson, with what he meant to be dangerous emphasis; but his face had suddenly become very pale. "You think you got the best of me the other day, but I'll fix you yet."
The two craft were out of earshot almost by this time, and none of the three lads on the Curlew thought it worth while to answer Donald Judson. The millionaire and his son occupied an island not far from the Pine Island Hotel. A few days before the incident we have just recorded, Jack, who hated cruelty in any form, had found Donald Judson, who often visited the hotel to display his extensive assortment of clothes, amusing himself by torturing a dog. When Jack told him to stop it the millionaire's son started to fight, and Jack, finding a quarrel forced upon him, ended it in the quickest way—by knocking the boy flat.
Donald slunk off, swearing to be revenged. But Jack had only laughed at him and advised him to forget the incident except as a lesson in kindness to animals. It appeared, however, that, far from forgetting his humiliation, Donald Judson was determined to avenge it even at the risk of placing his own life in danger.
"I wonder if he followed us up to-day on purpose to try to ram us or force us on a sandbar?" mused Noddy, as they sailed on.
"Looks like it," said Billy.
