Undisturbed, so far as anyone could see, Ned shoved the telegraph over till little by little the pointer stopped at "Full speed astern." He rang up on the bridge telephone.

"Confound him! So he has managed to get her afloat, after all," he muttered. "I didn't pile her up quick enough. Well, I'll get another chance, and this time I won't fall down."

Little by little the bulk of the gunboat began to slide backward off the shoal.
