Willy Croup was sitting on the floor of the saloon, sobbing and groaning, and Mrs. Cliff did not know what in the world was the matter with her. But Mr. Litchfield knew, and he knew also that it would be of no use to try to comfort her with any ordinary words of consolation. He was certain that she had not understood anything that she had said, not even, perhaps, the order to back the yacht, but the assertion of this would have made but little impression upon her agitated mind. But a thought struck him, and he hurried to Burke and told him quickly what had happened. Burke listened, and could not even now restrain a smile. "It's just like that dear Willy Croup," said he; "she's an angel!" "Will you be willing," said Mr. Litchfield, "to come and tell her that your orders could not have been forcibly and quickly enough impressed upon the engineer's mind in any other way?" Without answering, Burke ran to where Willy was still groaning. "Miss Croup," he exclaimed, "we owe our lives to you! If you hadn't sworn at the engineer, he never would have backed her in time, and we would all have been at the bottom of the sea!" Mrs. Cliff looked aghast, and Willy sprang to her feet. "Do you mean that, Mr. Burke?" she cried. "Yes," said he, "in such desperate danger you had to do it. It's like a crack on the back when you're choking. You were the only person able to repeat my orders, and you were bound to do it!" "Yes," said Mr. Litchfield, "and you saved the ship!" Willy looked at him a few moments in silence, then wiping her eyes, she said, "Well, you know more about managing a ship than I do, and I hope and trust I'll never be called upon to back one again!" Burke and most of the other men now gathered on deck, watching the _Dunkery Beacon_. She was still lying to, blowing off steam, and there seemed to be a good deal of confusion on her deck. Suddenly Burke saw a black object in the water near her starboard quarter. Gazing at it intently, his eyes began to glisten. In a few moments he exclaimed, "Look there! It's Shirley! He's swimming to the yacht!" Now everybody on deck was straining his eyes over the water, and Mrs. Cliff and Willy, who had heard Burke's cry, stood with the others. "Is it Shirley, really?" exclaimed Mrs. Cliff. "Are you sure that's his head in the water?" "Yes," replied Burke, "there's no mistake about it! He's taking his last chance and has slipped over the rail without nobody knowing it." "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!"
