"No; I don't think I do," said the lad frankly. "I feel a curious fluttering kind of sensation, as if my heart was beating very fast, but I don't think I'm frightened--I'm sure I'm not," he added gravely, and with a simple sincerity far removed from boastfulness. "How can you be sure?" said the doctor, giving him a searching look. "Because if I really were frightened I should cut the line." "Of course you would," said the doctor. "Stands to reason. But I didn't come out prepared for shark-fishing, so I'm beginning to think we may as well cut or break the line, and go back. We don't want to have far to row on such a day as this." "Oh, don't do that," cried Jack. "It's so exciting and strange to be dragged along like this." "What do you say to trying to get the fellow up to the surface, so as to have another look at him?" "But suppose it attacks us?" "I don't think there is any fear," said the mate, smiling. "Try and get it up then," said Jack eagerly. "Come and lend a hand, Edward," said the mate; and they began to take a slow, steady pull on the line, drawing in the strong hemp fathom by fathom, till the number of rings in the bottom of the boat showed that they must be near their captive, but there was no sign of it till another dozen yards were hauled in, and then, as Jack leaned over the bows, he could dimly see deep down a shadowy form going right onward, slightly agitating the water as it passed through. Then as the pair in the boat hauled, the dark shadow began to show more and more clearly, proving that the buoyancy of the boat was beginning to tell upon it, and draw it nearer to the surface. "Can't stand this much longer, Jack," said the doctor; "the line must break." "I wonder it has not parted before now," cried the mate. "It is of wonderfully good quality, and stretches like india-rubber. Hah! he's coming up now. Will you take the boat-hook and give him a prod, doctor, if he is disposed to show fight?" "Well, yes, unless you would like to, Jack." "Yes, I should like to," said the lad, with a couple of red spots appearing in his cheeks; and he bent down, picked up the light boat-hook, and stood with one foot upon the thwart, holding the implement as if it were a lance. "Bravo! Mr Jack," whispered Edward. "See him plainly?" said the mate. "Yes, very clearly now. It is not above six feet down, a great long black creature. Would it be a shark?" "Oh yes, that's a shark, sure enough," said the mate. "I saw him plainly enough when he took your fish. But you had better watch him, for at any moment the line may give way." Another pull or two resulted in the great fish being brought so close to the surface that its back fin showed from time to time. "Aren't we quite near enough?" said the doctor in a low tone to the mate; "it's a big, dangerous-looking creature."
