"Ahoy!" roared Jack. "That's done it," he added; "they've heard us." Five minutes later half a dozen of the _Titania's_ crew, headed by Harborough and with Pete bringing up the rear, arrived upon the scene. The rest of the crew were roaming over the other side of the island. "There's one thing," remarked Harborough in a low voice to Villiers, "we shan't have our rest disturbed tomorrow night prowling around for the youngster. I was afraid he had shot himself. What did he shoot, by the by?" "Two pigs," replied Jack. "Hurrah, massa!" shouted Pete, who happened to overhear the conversation. "Roast pork to-morrow!" "Right-o, Pete!" rejoined Villiers. "You can jolly well help to bring in the meat." CHAPTER XX Up and Down "All ready? Stand clear." With a deafening clatter the powerful little motor of the _Cormorant_ sea-plane fired, and the aluminium propeller revolved until it merged into a dazzling circle of light. Slowly, but with increasing momentum, the compact air-craft began to skim along the placid surface of the lagoon, leaving a long and ever-widening wake. It was the _Cormorant's_ first ascent since the trial flight at the works. The sea-plane's tanks were but half full in order that the single seater might accommodate a passenger. Claverhouse, leather-helmeted and goggled, was at the joy-stick. Behind him on a somewhat precarious perch strapped to one of the struts was Trevear, armed with a camera. Originally it had been Harborough's intention to equip the two sea-planes with a wireless-telephone outfit, but, further consideration ended in the proposal's rejection on the grounds that the practical results would not justify the initial outlay. The application of aerial photography would be of great service in locating the sunken _Fusi Yama_, and the view thus obtained would be of a more or less permanent value. Reporting by wireless telephone would have been satisfactory up to a certain point. There would not have been the delay entailed in the use of photography with its processes of developing and printing, but on the principle that the camera cannot lie Harborough hoped for definite and important results. There had been keen competition on the part of the _Titania's_ crew to "go up", but Harborough reminded the applicants that they were not joy-riding at a couple of guineas a flight, and proceeded to whittle down the aspirants for the part of aerial photographer, until Trevear, the reserve pilot, was alone left in the running. Every available boat carried by the _Titania_ was pressed into service to act in conjunction with the seaplane. Fitted with mark-buoys and sinkers, the boats paddled across the lagoon ready to buoy the wreck if luck enabled the airmen to spot it.
