"And I," added the commodore, "would like Tabu-Tabu's shin bone for a clarionet. Pendin' McGuffey's reflections on the hamperin' of crime in Kandavu, however, we'll turn our attention to the prime object of the expedition. We've had our little fun and it's high time we got down to business. It will be low tide at nine o'clock, so I suggest, Scraggs, that you order the mate and two seamen out in the big whaleboat, together with the divin' apparatus, and we'll go after pearl oysters and black coral. As for you, Mac, suppose you take the other boat and Tabu-Tabu and the king, and help the mate. Take a rifle along with you, and make them captives dive for pearl oysters until they're black in the face----" "Huh!" muttered the single-minded McGuffey. "What are they now? Sky blue?" "Of course," continued the commodore, "if a tiger shark happens along and picks the niggers up, it ain't none of our business. As for me and Scraggsy, we'll sit on deck and smoke. My head aches and I guess Scraggsy's in a similar fix." "Anythin' to be agreeable," acquiesced McGuffey. After breakfast Commodore Gibney ordered that the prisoners be brought before him. The cook served them with breakfast, and as they ate, the commodore reminded them that it was only through his personal efforts and his natural disinclination to return blow for blow that they were at that moment enjoying a square meal instead of swinging in the rigging. "I'm goin' to give you two yeggs a chance to reform," concluded Mr. Gibney, addressing Tabu-Tabu. "If you show us where we can get a cargo of black coral and work hard and faithful helpin' us to get it aboard, it may help you to comb a few gray hairs. I'm goin' to take the irons off now, but remember! At the first sign of the double-cross you're both shark meat." On behalf of himself and the king, Tabu-Tabu promised to behave, and McGuffey kicked them both into the small boat. The mate and two seamen followed in another boat, in which the air-pump and diving apparatus was carried, and Tabu-Tabu piloted them to a patch of still water just inside the reef. The water was so clear that McGuffey was enabled to make out vast marine gardens thickly sprinkled with the precious black coral. "Over you go, you two smokes," rasped McGuffey, menacing the captives with his rifle. "Dive deep, my hearties, and bring up what you can find, and if a shark comes along and takes a nip out of your hind leg, don't expect no help from B. McGuffey, Esquire--because you won't get any."
