"And can he swim so far?" gasped Willy.

"Oh, he can do that," answered Burke. "I'd steam up closer if I wasn't afraid of attracting attention. If they'd get sight of him they'd fire at him, but he can do it if he's let alone!"

Not a word was now said. Scarcely a breath seemed to come or go. Everybody was gazing steadfastly and rigidly at the swimmer, who with steady, powerful strokes was making a straight line over the gently rolling waves towards the yacht. Although they did not so express it to themselves, the coming of that swimmer meant everything to the pale, expectant people on the Summer Shelter. If he should reach them, not only would he be saved, but they could steam away to peace and safety.

On swam Shirley, evenly and steadily, until he had nearly passed half the distance between the two vessels, when suddenly a knot of men were seen looking over the rail of the Dunkery. Then there was a commotion. Then a man was seen standing up high, a gun in his hand. Willy uttered a stifled scream, and Mrs. Cliff seized her companion by the arm with such force that her nails nearly entered the flesh, and almost in the same instant there rang out from the yacht the report of eight rifles.

Every man had fired at the fellow with the gun, even Burdette in the pilot house. Some of the balls had gone high up into the rigging, and some had rattled against the hull of the steamer, but the man with the gun disappeared in a flash. Whether he had been hit or frightened, nobody knew. Shirley, startled at this tremendous volley, turned a quick backward glance and then dived, but soon reappeared again, striking out as before for the yacht.

"Now, then," shouted Burke, "keep your eyes on the rail of that steamer! If a man shows his head, fire at it!"

If this action had been necessary, very few of the rifles in the hands of the members of the late Synod would have been fired, for most of them did not know how to recharge their weapons. But there was no need even for Burke to draw a bead on a pirate head, for now not a man could be seen on the Dunkery Beacon. They had evidently been so surprised and astounded by a volley of rifle shots from this pleasure yacht, which they had supposed to be as harmless as a floating log, that every man on deck had crouched behind the bulwarks.

Now Burke gave orders to steam slowly forward, and for everybody to keep covered as much as possible; and when in a few minutes the yacht's engine stopped and Shirley swam slowly around her stern, there was a rush to the other side of the deck, a life preserver was dropped to the swimmer, steps were let down, and the next minute Shirley was on deck, Burke's strong arm fairly lifting him in over the rail. In a few moments the deck of the yacht was the scene of wild and excited welcome and delight. Each person on board felt as if a brother had suddenly been snatched from fearful danger and returned to their midst.

"I can't tell you anything now," said Shirley. "Give me a dram, and let me get on some dry clothes! And now all of you go and attend to what you've got to do. Don't bother about that steamer—she'll go down in half an hour! She's got a big hole stove in her bow!"

With a cry of surprise Burke turned and looked out at the Dunkery Beacon. Even now she had keeled over to starboard so much that her deck was visible, and her head was already lower than her stern. "She'll sink," he cried, "with all that gold on board!"
