Percy attacked the bag with an appetite equal to Jim's. Malcolm's Ledges were near, breaking white half-way from the Ball to Seal Island. To Percy's ears the roar of the surf sounded louder.

"Sea's making up a bit, isn't it, Jim?"

"Yes; but I don't think it'll amount to anything for a long time yet."

Down swept a squall from the north, roughening and darkening the water. The dory careened a trifle as it smote her side.

"Well, Perce, we're more than a third of the way home. There's Brimstone Point, eight miles ahead. We may see a little rough water before we get there. Lucky you're not seasick nowadays!"

The squall passed, but left a steady breeze blowing in its wake. The sky was gray, the sea leaden. The horizon all around seemed to be contracting, and the familiar islands were losing their height.

They ran to leeward of the breaker on Gully Ledge, and passed into smooth water under the protecting barrier of Seal Island. Pliny Ferguson's shack was in plain view, and its owner came out and swung his hand to them. Spurling remembered Captain Higgins's advice, and hesitated.

"What do you say, Perce? I'll put it up to you. Shall we keep on or stop here with Pliny? Seems to me there isn't the least doubt about our reaching the island before dark; but I don't want to make you run any needless risk. So I'll do as you say. Pliny'll be glad to make us comfortable, and we can slip across after the gale is over."

Percy scanned the steep, desolate cliffs a half-mile to the north.

"What would you do if you were alone, Jim?"
