"Look here!" he cried, standing up and facing the red-faced man, "I don't know who you are, and I don't care. But I'll tell you one thing--you'll pay for the damage you did to my boat!"

"I'll pay for it? Come, that's pretty good! Ha! Ha!" laughed the self-important man. "Why, I was thinking of making a complaint against you for crossing my course that way. If I find my boat is damaged I shall certainly do so anyhow. Have we suffered any damage, Snuffin?" and he looked back at a grimy-faced mechinician who was oiling the big, throbbing motor, which was now running with the clutch out.

"No, sir, I don't think we're damaged, sir," answered the man, deferentially.

"Well, it's a lucky thing for these land-lubbers that we aren't. I should certainly sue them. The idea of crossing my course the way they did. Weren't they in the wrong, Snuffin?"

The man hesitated for a moment, and glanced at Tom and Ned, as though asking their indulgence.

"Well, I asked you a question, Snuffin!" exclaimed the red-faced man sharply.

"Yes--yes, sir, they shouldn't have turned the way they did," answered the man, in a low voice.

"Well, of all the nerve!" murmured Tom, and stopped his motor. Then, stepping to the side of his disabled and leaking boat, he exclaimed:

"Look here! Either you folks don't know anything about navigation rules, or you aren't heeding them. I had a perfect right to turn and go ashore when I did, for I found my engine was out of order, and I wanted to fix it. I blew the usual signal on the whistle, showing my intention to turn off my course, and if you had been listening you would have heard it."

"If you had even been watching you would have seen me shift, and then, coming on at the speed you did, it was your place to warn me by a whistle, so that I could keep straight on until you had passed me."
