He took a more cheerful view of life when the _Titania_ got under way and proceeded seawards, but at the same time that evolution considerably mystified him. He could not understand why the Englishman should retire so tamely from the argument when he had undisputable evidence to support his case. Von Giespert was on the point of shaking hands with himself and abusing some of his crew--an indication that he was regaining his normal state of mind--when Strauss announced that the _Titania_ had turned sixteen points to starboard and was again making for the island. "We'll fight her," declared von Giespert vehemently, for he realized that the game was a desperate one. "Serve out the arms, Herr Strauss. Himmel! What would I give now for a submerged torpedo-tube? Would that she piled herself upon the reef. She nearly did it last time." "Harborough is more cautious this time," observed Strauss. "He's coming in under power." "He is, curse him," growled the other. The two Germans watched in silence as the _Titania_, with her exhaust chortling noisily, passed through the narrow gap and starboarded helm, steering for the opposite part of the lagoon to that where the _Zug_ lay at anchor. That was another puzzler to the already bewildered von Giespert. Presently the yacht reversed engines and lost way broadside on to and at about a mile from her rival. Then, to the consternation of the crew of the _Zug_, a large gun, of a calibre certainly not less than 4.7 inches, was ominously visible betwixt fore- and main-masts. Simultaneously, and without any preparatory signal, a hoist of the letters VOX--"I am going to semaphore to you"--fluttered from the _Titania's_ main truck. Slowly, reluctantly, the answering pennant was displayed from the _Zug_. "I thought you informed me that yonder yacht was unarmed," exclaimed von Giespert, turning furiously upon his henchman, Strauss. "She was when we left Southampton, Herr Kapitan," replied Strauss. "That I can swear to, because we had her under observation all the time. Of course, she might have----" "They're semaphoring," interrupted von Giespert. He himself could not follow the quick movements of the red and yellow hand-flags, but most of the _Zug's_ crew could. More than that, they could read the peremptory message although it was sent in English. "Hand over my airman, Claverhouse, instantly," it read, "or I will blow your bridge and charthouse to blazes." Von Giespert chose the first alternative. Three quarters of an hour later the _Titania_, with Alec Claverhouse once more on board, was bowling along at a steady nine knots for Nua Leha. Then it was that Harborough, with a playful movement of one hand, toppled the formidable 4.7 inch gun through the hatch into the fore-hold. The mounting followed with a distinctly "tinny" sound. The feat was an easy one, since the "gun" consisted of a twelve-foot length of stove-pipe, and the mounting a piece of sheet iron and an empty oil-drum.
