Imagine the horror of the six scouts when they realized that they were now completely at the mercy of the storm, since the last barrier seemed to have given way when the treacherous engine broke down.

Even brave-hearted Thad Brewster felt that their case was desperate: and he knew in his secret heart that if they managed to escape a serious situation it must be through a narrow gap.

At the same time Thad always made it a point to put on a good face when up against trouble. This was of course partly done because of his comrades, since, as the scout-master he felt more responsibility than fell to the share of the rest.

Bumpus had been hanging on like a good fellow. He greatly feared lest some sudden violent lurch of the boat toss him headlong into that yeasty sea; which he was gazing upon with terror.

At the same time Bumpus had been closely observing the actions of the eccentric motor, and was one of the first to discover that it had petered out, giving up the ghost completely, as Giraffe would have said.

"Oh! what can we do now, Thad?" shouted the stout scout, as usual turning to the quick-witted one in an emergency; but for once even Thad was at his wit's ends to know what to attempt, the situation was that desperate.

"Everybody hold on!" was all Thad called back.

There was hardly any need of this injunction, for each fellow had managed to brace himself, so that unless the boat actually "turned turtle," or at least was thrown on her beam ends, they could not be dislodged.

Thad was straining his eyesight as best he could, endeavoring to see ahead. The furious wind of course made this a difficult task, because it not only sent the waves high, but as these broke into foam along their crests, this was actually cut off as with an invisible knife, and blown away in the shape of flying spud; so that the very air was surcharged with a fine mist, rendering it hard to distinguish anything fifty feet off.

Of course it was the island that the young leader was striving to see all this while. He knew as well as anything that the one slim hope remaining to them must rest upon their chance of finding some sort of shelter behind this oasis in the watery waste.
