"What're those half-barrels, full of small rope?"

"Trawl-tubs; and those coils inside are the trawls. Each tub holds about five hundred fathoms of ground-line, with a thirty-eight-inch ganging, or short line with a hook on its end, tied every five feet; so there're between five hundred and six hundred hooks to every tub. One man alone can bait and handle four tubs of trawl. Two of us are going to fish together, so we ought to be able to swing six tubs without any trouble."

Percy looked about the house. Other barrels stood there; a net was draped over the beams; many coils of small rope were hung along the walls or piled on the floor. His attention was attracted by a large heap of peculiarly shaped pieces of wood. Each was eighteen inches long, five inches square at one end, and tapered almost to a point at the other, near which a hole was bored; they were painted white, encircled by a single green stripe, and bore the brand "SP."

"Cedar lobster-buoys," said Jim. "SP's my Uncle Tom's brand. Every man has a different kind, so his floats won't get mixed with anybody else's. Now let's take these tubs of trawl aboard the sloop."

At six the Barracouta, carrying the five boys and towing the dory, started from Sprowl's Cove for Matinicus. It was so calm that the sails were of little assistance, and they had to depend almost entirely on the engine. Rounding Brimstone Point, they headed slightly north of west for Seal Island, about six miles away.

Everybody took his turn at steering, Jim acting as instructor.

"Any one of you may be called on to handle this boat alone some time in the next three months, and you can't begin learning how any too early."

Percy's experience with automobiles stood him in good stead. He was naturally interested in machinery, and soon mastered the details of the Barracouta's engine. The others also showed themselves apt pupils.

At half past seven the high cliffs of Seal Island lay to the north. Passing for a mile along its rocky shores, they kept on toward Matinicus, now rising into view. Jim pointed to a breaker a little south of their course.

"Malcolm's Ledges! A bad bunch of rocks. Years ago a fishing-schooner struck there in the night. Crew thought at first they'd reached safety, but they soon found it was only a half-tide ledge. The vessel heaved over it when the water rose, and sunk, so that only her topmast stuck out. One man, the sole survivor, hung to that. He was taken off in the morning, but his arm was worn almost to the bone by the swaying of the mast."
