"I think Captain Blastblow intends to return soon," I added, for I could not think of any explanation of his singular conduct. I certainly could not reason out any plausible occasion for such a violation of his orders as that in which he seemed to be engaged.

"Perhaps he has run off with the yacht, and intends to become a pirate, or something of that sort," suggested Gus Shepard.

"Nonsense, my son! The Islander is not an armed vessel, and Captain Blastblow is not a pirate," replied Colonel Shepard. "Do you suppose anything was out of order on board of the steamer, Captain Alick?"

"It is possible; but if such was the case, the captain would hardly have gone so far down the river," I replied. "If the Islander had needed any more repairs, Captain Blastblow would have remained in Jacksonville and attended to them."

"Perhaps he wishes to become better acquainted with the vessel before he takes her to sea," added the colonel.

"He might have done that yesterday. He would not have waited until you were ready to sail, and then gone off on an experimental cruise," I answered.

"An experimental cruise!" exclaimed Owen. "What a terrible expression. I hope Captain Blastblow don't use such expressions. If he does, he has gone out to sea where he can have room enough to unsnarl his tongue."

"Captain Blastblow is an American, and he is used to such little trials," I replied.

"What shall be done?" asked Colonel Shepard.

"I think you had better go on board of the Sylvania, with your baggage, and we will stand down the river," I replied, promptly, for I had kept this idea in my mind for some time. "We can at least follow the Islander, and when we come up with her you can go on board of her."
