"There is no port we can enter before we reach Key West, madam. With the wind as it is now, and blowing hard, I am afraid to go any nearer the reefs than we are now."

"I hear that a great many vessels are wrecked on the Florida Reefs," added the lady.

"That is quite true, Mrs. Shepard; and for that reason I shall not approach them any nearer than we are now. As long as we have plenty of sea room, I do not apprehend any particular danger."

The rain began to fall about six, and the weather was so thick we could no longer see the Islander. The last time we had seen her she must have been some miles farther to the northward than the Sylvania, and I was satisfied that Captain Blastblow had not gained anything by going inside of the reefs. As I made it out from the chart, he had twice been obliged to go to the eastward over two miles, in order to keep in the deepest water. I suspected that he had been aground, and had to wait for the tide; for at dark, when we saw the steamer for the last time, we were at least five miles farther south.

"We will keep her going as briskly as the heavy sea will permit, until about midnight; and then we will ease off till daylight. Then I think we shall get another sight of the Islander," I said to the mate, as he was about to turn in at eight.

"I don't think there is any danger of her getting ahead faster than we do," replied the mate, with a yawn. "I believe I shall sleep well, if I don't get pitched out of my berth."

He was leaving the pilot-house, when the distant report of a gun came to our ears. I concluded at once that the Islander was in trouble.
