"I can hardly believe it," added Mr. Watson.

"It is another plan to extort money from you."

Levi persisted in his belief. Putting this and that together, he could almost demonstrate that Mat Mogmore was in the employ of Dock Vincent; indeed, Dock had told him that Mat intended to sail for Australia with him. Mr. Watson decided to return immediately to Rockport, and the yacht lay to off the railroad wharf long enough to land him. He took the morning train for Boston, and reached home at two o'clock.

The Starry Flag did not sail in the race that day. As soon as her owner had been landed, she was headed for Cape Ann again, and arrived before night. Levi was bewildered and confounded by the shock of the blow which had fallen upon him and the Watson family. He could do nothing, and in his inactivity he chafed like a caged lion. Mr. Watson had gone to Boston soon after his arrival, taking Mr. Gayles with him. He did not return till the next day. He had chartered a swift steamer, and the constable, with other officers, had gone in pursuit of the Caribbee.

In the morning mail, on the second day after the disappearance of Bessie, came a letter to her father. Levi was present when it was opened, and it contained a full confirmation of his theory that Bessie had been carried off in the Caribbee, and was now going half round the world to Australia. The letter was written by Dock Vincent, and dated ten days before its receipt. The villain assured the distracted parents that Bessie should be kindly cared for by Mrs. Vincent, and should be restored to her friends as soon as possible after her father had paid over to Mr. Fairfield the sum of seventy thousand dollars.

Mr. Watson dropped the letter on the floor, and breathed a deep sigh. He would have given double the sum for the return of Bessie; but his conscience would not permit him to reward villany like that of Dock Vincent.

"Levi, your uncle is concerned in this affair," said Mr. Watson, turning to the young skipper with a sad look.

"I suppose he is. I will go and see him at once."

"I will go with you."

They went.
