"It must be the shipwrecked seamen," explained the lady. "Their ship was broken on the crags in the storm last week, and they have been living in one of the caves. They are evil-looking men, and the islanders fear them."

"The shot seemed to me to come from where the Aurora is lying," cried Ben in alarm. "I'll engage 'tis the quartermaster signalling to me to go back." And giving a hasty seaman's salute, he abruptly left his strange companion, and ran across the moor in the direction of the brig. An unaccountable dread of some impending disaster oppressed him as he ran. From the top of the hill he saw that the Aurora was still riding safe at her moorings; but his quick eye discovered the figures of two men moving upon her quarter-deck. Who could they be? He made his way down to the beach. He glanced at the water's edge where he had left his boat, but the boat was gone.

"I'm not by half so ill as Ben thinks," ruminated the quartermaster, as he lay in his lonely hammock pondering over the situation during Ben's absence. "I do believe I'm fit even now to take watch and watch about with him. 'Tis hard on the lad to leave him to do all the work, and me able to lend a hand." He glanced towards the open port, through which he could see a snowy-white seagull calmly floating on the green water. Then looking down at the deck below him, he added, "Blamed if I don't get out of this and see what I can do." He sat up, dangling his trembling legs over the side of his hammock; his toes were but a dozen inches from the flooring.

"I believe I can do it," he went on; and turning over, he gripped the hammock with his two hands, and swung himself slowly and cautiously down until his feet touched the boards.

His limbs were shaky, and his head seemed to swim; but stepping out, he succeeded in tottering across to the nearest bulkhead. Supporting himself by his outstretched hands, he went step by step along the gangway to the foot of the companion-way. Slowly he mounted the stairs, until the fresh sea-air played upon his bare head. He sat on the top stair for a long time, drinking in the sweet cool atmosphere, and looking up into the blue sky and its sailing white clouds.

"Seems to me I'd best step aft to the cap'n's room," he muttered to himself. "'Tis no place for the likes o' me to enter, certainly; but being as Ben and me are in charge of the brig, why, 'tis no court-martial matter. Nay, now I come to think of it, 'tis my duty to go in." And rising with difficulty to his feet, he staggered aft and boldly but respectfully entered.

The first thing that caught his eye was the captain's silver ink-pot on the table; then it was the mingled red and blue folds of the Union Jack lying across the dead body of the captain in the inner sleeping-room.

"Good boy, Ben," he said. "You haven't forgot what's due to a king's officer. You and me'll have to act the parson soon, too, if we can lay our hands on a prayer-book. Mayhap you know the words without the book; you must ha' heard 'em pretty often lately. But I don't know 'em, except 'We therefore commit his body to the deep until the sea shall give up her dead——'"

An unexpected sound startled the quartermaster in his ruminations. It was a man's gruff voice, and it came from outside, below the brig's counter.
