"Where is the other half?" I asked, blankly.

"I have no doubt this half belongs to my friend Mr. Boomsby; and I have no more doubt Cornwood would have stolen it by the time they got to New Orleans," added the colonel.

We concluded that it would not be as easy to find the second half of the treasure as it had been the first.

CHAPTER XX.

THE THEORY AND THE FACTS.

We spent an hour in searching in every nook and corner of the cabin for the other half of the lost treasure. Cornwood had not been stupid enough to put it under the companion-way; and Nick had been stupid enough to let his companion know where he had hidden his own share. As Colonel Shepard had suggested, it was probable that the Floridian meant to take it before he went on shore at New Orleans. Cornwood had not concealed his share of the treasure in the cabin of the Islander, and we could think of no other place where he was at all likely to deposit it.

"I think he has too long a head to hide his money anywhere," interposed Captain Blastblow. "I should say that any man was a natural fool to hide his money in a vessel, under such circumstances as these fellows came on board of the steamer. In my opinion, he has concealed the money on his person, for you seem to have no doubt that he divided with the young swell."

"That looks very reasonable," added Colonel Shepard. "I think if I had a large sum on board of a vessel, I should provide myself with a money-belt, and keep the treasure in it at all times."

"All we have to do is to search him," said Captain Blastblow. "We shall soon find out whether or not he is a party to the robbery. I suppose there isn't any doubt about the young swell, as the steward called him, and which I think is the best description of him."
