"You're on," echoed Noddy, not to be outdone. But, as a matter of fact, the red-headed lad, who had eaten far more than the others, wasn't feeling very well. However, he did not wish to spoil the fun, so he didn't say anything.

Jack and Billy struck out with long, strong strokes.

"Come on," cried Jack, looking back at Noddy, who was left behind, and who began to feel worse and worse. "What's the trouble—want a tow-rope?"

"I'll beat you yet, Jack Ready," cried Noddy, fighting off a feeling of nausea.

"I guess I went in the water too soon after eating," he thought. "It will wear off."

"Help!"

The single, half-choked cry for aid reached the ears of Jack and Billy when they were almost at the anchored boat, which was the objective point of the race.

"Great Cæsar!" burst from Jack. "What's up now?"

He turned round just in time to see Noddy's arms go up in the air. Then the red-headed lad sank out of sight like a stone.

"He can't be fooling, can he?" exclaimed Billy nervously.
