Little did Charles Dicey and his sisters think of the fearful dangers to which their brother Willy was exposed. The "Crusader" sailed on over the smooth sea, with her white canvas spread out, towering to the sky, studding-sails on either side reaching to the very surface of the water. An awning had been spread over the after-part of the ship, and beneath it the cabin passengers assembled, sheltered from the hot rays of the sun. Neither Charles nor Mr Paget were ever idle, and their example generally induced many of their companions to work also. Mrs Clagget, if she did nothing else, always contrived to keep her tongue going. Emily and May were usually well employed. Their attention, however, was frequently called to the various objects which appeared around them. They enjoyed watching the flights of flying-fish which darted with the speed of arrows out of the water, hovered like birds in the air for a few seconds, scarcely touching the foam-crested seas, and then sunk quickly again beneath the surface. "How beautiful and blue are the reflections on their glittering wings, how transparent their tiny bodies, how light their movements!" observed Emily; "they look like ocean elves, as they float through the air. What a happy life they must lead--now in the pure ocean, now getting an uninterrupted sight of the glorious sun and the clear sky above them." "They would have a very different tale to tell, Miss Dicey, if they could speak to you," observed Mr Paget. "Could your eyes pierce through the surface, you would see some savage bonitos or dolphins pursuing the hapless fish who visit the air, not for amusement, but in the hopes of escaping from their persecutors." Just then a large covey was seen to rise abeam close to the ship. They flew high into the air, and in an instant the deck was covered with their floundering bodies; their wings, dried by the heat of the sun, no longer spread out, they looked like ordinary fish. "Catch them, catch them," cried Mrs Clagget; "they will make a delightful dish for dinner." "Poor creatures--how unromantic you are," said Emily. "I am practical, my dear. I pride myself on being practical," answered Mrs Clagget. "I prefer eating them myself to allowing the dolphins to have them for their supper." Jumbo, the cook's mate, seemed to be of Mrs Clagget's opinion, for in an instant he was among the poor fish, tumbling them into his bucket as fast as he could pick them up.
