I gave the pilot my views of the relative speed of the two vessels, though I told him that Captain Blastblow might get a higher rate of speed out of her than any one had done before.

"We shall soon see which sails fastest," said Captain Cayo. "The Islander has laid her course for the South-west Pass of the Mississippi. All you have to do is to follow her. There is our pilot-boat; and this is as far as we usually take vessels."

"But I don't care to have you leave us here, Captain Cayo," I replied. "It is clear enough that the Islander intends to keep out of our way. She may run in among the Dry Tortugas, and having a pilot on board, she could easily elude us."

"She might do that when she finds you are gaining on her, as I see you are, for we have made half a knot on her since we came out of the channel. But if we leave the pilot-boat behind, I can't get off the steamer when you don't want me any longer. Besides, it looks like a change of weather, and pilots are in demand when it is foggy or blows, at this season of the year."

"What sort of weather do you expect next?" I asked.

"The wind will work round to the south-west, and then it will be foggy," replied the pilot, scanning the horizon.

"Can't you go to New Orleans, or remain on board till we meet a steamer for Key West?" I suggested.

"I should be very happy to go to New Orleans with you, for there will be no steamer for Key West for several days. But I am not a pilot for the Mississippi River, and you will have to pay another just the same as though I were not on board."

He named his price, besides expenses; and as it was reasonable, I accepted it at once. My experience the night before, when I found the Sylvania was ten miles from where I supposed she was, made me extremely cautious. I felt entirely competent to take the steamer to the South-east Pass of the Mississippi; but it was evident that Cornwood had obtained control of the Islander, acting as the agent of Colonel Shepard, and that he would not permit the Sylvania to come near her if he could avoid it. Probably the Conch who had acted as her pilot so far would understand the channels of the Tortugas, and could easily take the Islander where I should not care to follow her.

The pilot-boat lay very nearly in our course, and a boat put off from her as we approached. Captain Cayo stopped the steamer when the boat was abreast of her. He jumped upon the rail, and told the oarsmen that he was going to New Orleans.
