The hot sun had gone under a cloud, and the ocean was no longer blue, but gray. It was hot and still.
Now when Sunny Boy sat up to look about him, something happened.
“Chug-chug, chug-chug!” said the motor-boat, carrying Mr. and Mrs. Horton and Captain Franklin.
“That looks like a rowboat,” whispered the captain to Mr. Horton, putting down his field glasses. “Don’t tell Mrs. Horton—it’s empty.”
But Mrs. Horton had heard, and she took the glasses before any one could stop her. Just as she put them to her eyes Sunny Boy sat up in the boat.
“He’s in it!” cried Mrs. Horton joyfully. “See, Harry, that little black dot must be his head. Oh, hurry, Captain, hurry!”
“Chug-chug, chug-chug!” gurgled the swift little motor-boat, fairly leaping through the water. “I’ll do my best. Chug-chug.”
And it wasn’t very long before Sunny Boy heard the noise of the engine and he stood up to look. There was a boat coming straight toward him.
“Sit still!” called Mr. Horton. “Don’t jump about, Sunny Boy. We’ll be right there.”
The motor-boat scraped alongside, and Sunny was lifted over and placed on his mother’s lap.
