"What do you want?" he asked deliberately, and there was a subtle menace in his tones. As for Neils Halvorsen, thinking only of the surprise he had in store for his old employer, he replied evasively:

"Aye bane want job."

"Well, I'm Captain Scraggs, and I haven't any job for you. Get off my boat and wait until you're invited before you come aboard again."

For nearly half a minute Neils Halvorsen stared open-mouthed at the spurious Captain Scraggs, while slowly there sifted through his brain the notion that he had happened across the track of a deep and bloody mystery of the seas. There was "something rotten in Denmark." Of that Neils Halvorsen was certain. More he could not be certain of until he had paved the way for a complete investigation, and as a preliminary step toward that end he clinched his fist and sprang swiftly toward the bogus skipper.

"Aye tank you bane damn liar," he muttered, and struck home, straight and true, to the point of the jaw. The man went down, and in an instant Neils was on top of him. Off came the sailor's belt, the hands of the half-stunned man were quickly tied behind him, and before he had time to realize what had happened Neils had cut a length of cord from a trailing halyard and tied his feet securely, after which he gagged him with his bandana handkerchief.

A quick circuit of the ship convinced Neils Halvorsen that the remainder of the dastard crew were evidently ashore, so he descended to the cabin in search of further evidence of crime. He was quite prepared to find Captain Scraggs's master's certificate in its familiar oaken frame, hanging on the cabin wall, but he was dumfounded to observe, hanging on the wall in a similar and equally familiar frame, the certificate of Adelbert P. Gibney as first mate of steam or sail, any ocean and any tonnage. But still a third framed certificate hung on the wall, and Neils again scratched his head when he read the wording that set forth the legal qualifications of Bartholomew McGuffey to hold down a job as chief engineer of coastwise vessels up to 1,200 tons net register.

It was patent, even to the dull-witted Swede, that there had been foul play somewhere, and the schooner's log, lying open on the table, seemed to offer the first means at hand for a solution of the mystery. Eagerly Neils turned to the last entry. It was not in Captain Scraggs's handwriting, and contained nothing more interesting than the stereotyped reports of daily observations, currents, weather conditions, etc., including a notation of arrival that day at Honolulu. Slowly Halvorsen turned the leaves backward, until at last he was rewarded by a glimpse of a different handwriting. It was the last entry under that particular handwriting, and read as follows:

June 21, 19—. Took an observation at noon, and find that we are in 20-48 S., 178-4 W. At this rate should lift Tuvana-tholo early this afternoon. All hands well and looking forward to the fun at Tuvana. Bent a new flying jib this morning and had the king and Tabu-Tabu holystone the deck.

A.P. Gibney.

Neils Halvorsen sat down to think, and after several minutes of this unusual exercise it appeared to the Swede that he had stumbled upon a clue to the situation. The last entry in the log kept by Mr. Gibney was under date of June 21st—just eleven days ago, and on that date Mr. Gibney had been looking forward to some fun at Tuvana-tholo. Now where was that island and what kind of a place was it?
