"Allowing that I wrote 'seven p.m.,' or that I did not write either morning or evening, what is Captain Blastblow doing down here?" demanded Colonel Shepard, warmly.

"If he understood that you were not to sail till this evening, he may have brought the Islander out here to try her, and enable him to get accustomed to her ways before he took on board his passengers. That is all the explanation I can suggest, but I don't think it will hold water. He knows very well, for he has been around Cape Horn several times, that if he comes out here in a fog, he may not be able to get back to Jacksonville in time to take you on board to-night, or even to-morrow or next day."

"If Captain Blastblow had any doubt in regard to my orders, he could have sent one of his men up to my house, and ascertained just what I intended," said the owner, rather wrathfully.

"That is what I should have done; but Captain Blastblow has had more experience than I have," I replied, with a smile.

"Did you notice anything unusual about the Islander, or the conduct of those on board of her, when you saw her this morning, Captain Alick?" continued the colonel.

"Nothing at all, sir. A boat went off to her a few moments before she weighed her anchor," I answered. "There were two persons in the boat when it went alongside the Islander, but only one returned to the shore in it. I concluded some one of her officers or crew had remained ashore over night, and came off in a shore boat. I did not think of the boat till you asked the question."

"I don't see that the boat throws any light on the transaction," mused the owner. "We don't know who was in the boat, though if we were in Jacksonville, we could easily ascertain."

"I don't have any idea that we shall know anything about this matter until we overhaul the Islander," I added. "We can guess for the next week, but we are as likely to guess wrong as right."

"I can't help being considerably disturbed about this mysterious conduct of Captain Blastblow; but I do not see that we are likely to be any wiser in regard to it, as Captain Alick says, till we see the captain," replied the colonel. "We have got to make the best of it, and be patient till we learn more. What do you think of it, Major Garningham?"

"I don't think it is possible to form an intelligent opinion without further information in regard to the facts," replied my father. "I am more inclined to believe that Captain Blastblow has made a mistake of some kind, than that he means anything wrong. It would be worse than folly for him to attempt to run away with the steam-yacht, for he is sure to be discovered and punished."
