"Now for the terror!" remarked George, as later in the afternoon they approached the spot where Watchapreague lay.

Ahead they could see the whitecaps marking the fierce cross currents that have given this half-mile wide inlet its bad name. Many a wreck of shore boats has taken place here, and lives been lost.

"We might as well get over now, as in the morning, for the tide is as good as it will ever be. Those whitecaps are caused by the wind blowing from the shore, and the tide coming in," Jack decided, as they advanced steadily on.

"And in case of any accident, then, a fellow couldn't be carried out to sea," George remarked, with what seemed like a distinct look of relief.

So the start was made. All around them the water fairly boiled, and unseen influences apparently tugged at the frail little craft, as though the fingers of those fabled monsters were gripping their keels.

They were just about the middle and most dangerous spot when George gave a sudden cry. It was echoed by a wail from Nick. Looking up, Jack discovered a sight that thrilled him to the core. The erratic Wireless had chosen to play its skipper a nasty trick at just the time it should have been on its best behavior, coming to a stop with such abruptness that poor Nick lost his hold forward, and went splashing into the water like a giant frog!
