"Barnacles on the vessel's bottom," explained the skipper.

"Yes, and we never cleaned them off, as you told us to," said Cracker Bob Jones, remorsefully.

"Then," continued Cal, "I caught hold of something, and my head came out of water, and as soon as I could I began to holler. I guess I hollered more'n an hour before Captain Crotty came, and I was afraid nobody ever would come; but now it's all right, only I don't want to have anything more to do with mermaids—never!"

"I found the poor little chap sitting straddle of the rudder," commented the skipper, "and pretty nigh ready to drop off from exhaustion; but, thank God, I was in time."

"Oh!" cried Will Rogers. "Isn't it splendid to have him safe back again, and aren't we just the happiest fellows in the world at this minute? But I say, Captain, we won't have to go back to Berks, after all—that is, not until our cruise is finished—will we?"

"Humph!" answered the skipper, as he turned to go on deck; "I don't know about that."

CHAPTER VI.

MUTINY AND SHIPWRECK.

The Rangers ate supper in their bunks, which they thought great fun, and then in their overflowing joy they skylarked and threw pillows at one another, until an unlucky shot brought the lantern down with a crash. As this disaster not only came near to setting the sloop on fire, but left them in total darkness, it also had the effect of so quieting them that several actually dropped asleep, while the others discussed their prospects in low tones, and wondered if they really would have to go back without finishing the cruise as planned.

By this time young Jabe, with a sailor's happy facility for taking a nap at any time, was sound asleep on deck forward, while the skipper sat aft in a big chair, leaning against the tiller, thoughtfully puffing at his pipe, and so affected by the soothing influences of the night that he was wondering if, after all, he should have the heart to disappoint the boys of their cruise.
