“Perhaps not.”

Then a wave curled over the side of the boat and came near swamping her. Wallace cried out in fear, but Frank ripped out a seat and used it as a paddle to aid in holding the boat steady.

“Take your cap and try to bail out some of that water,” directed Frank. “We must keep afloat as long as we can.”

Wallace obeyed.

Now they could hear a roaring that grew louder and louder with each passing moment. It was an awesome sound, and Wallace shuddered and grew sick at heart.

“What is that?” he asked, his voice trembling.

“It must be the sea beating on a ledge,” answered Frank.

“Great Heaven! Then we are being carried straight upon it!”

“It seems that way. See if you can tear out another seat. We must try to paddle past the ledge.”

Merry’s companion did his best, but he could not get out another seat, and the roaring of the water told that each moment was carrying them nearer and nearer to the fatal ledge.
