Norman Wentworth had risen, and with blazing eyes, his oar uplifted, was scrambling toward the bow to repel the boarder, when the latter disappeared.

Norman gazed at the spot with staring eyes.

When he came to the top, he was pulling the other boy up with him.

But fortunately Norman kept his head, and with a supreme effort breaking the drowning boy's hold, he drew him to the top once more.
