"But I did not write that letter, Captain Blastblow," repeated the owner; and by this time we were all rather amused at the straightforward earnestness of the captain of the Islander. "Let me see the letter, if you please."

The captain handed him the letter. Colonel Shepard examined it critically. He shook his head as he did so.

"I must acknowledge that the writing looks very much like mine," he said, after he had read it through and examined it in every part. "Who could have written it?"

"Nick Boomsby wrote it, without a doubt," I replied. "I went to school with him, and he was a good penman, though that was about all he was as a scholar."

"Is that my friend, Mr. Boomsby?" asked the colonel, laughing heartily.

"The same person; and he has become a swell of the first magnitude," I replied. "If I had known, or suspected, before we got to Key West, that Nick was on board of her, I could have explained the strange conduct of the Islander, and why she so carefully kept out of our way."

I gave a full account of the robbery of the bank messenger in the saloon of Nick's father, dwelling upon the efforts Nick had made to arrest Buckner. I stated that he had tried to obtain a passage to New Orleans in the Sylvania, that I had refused to let him go in her, and had taken care that he did not become a stowaway on board of her. I added that Nick told me of his intention to run away from his home, and seek his fortune in some other part of the country.

"I have no doubt that Nick stole the four thousand dollars the messenger laid on the counter, and resorted to the trick of forging a letter to Captain Blastblow, so that he could get the Islander off ahead of the Sylvania," I continued.

"But how is it that Cornwood did not stop the Islander at Key West, as it appears he got on board of her there?" asked Colonel Shepard, deeply interested in the narrative.

"I think you will have to ask Cornwood about that," I replied. "I am a Yankee, and I can guess what he meant."
