"I should like to see him when he's dead." "I'm afraid there will be no shark to see," said the captain grimly, as the gig surged through the water.
"Why, there's his back fin, and there it is again and again," cried Mark.

"How he keeps curving out of the water and dashing about! I say, father, row back and put him out of his misery." "I daresay he is out of it by this time, my boy," said the captain, rowing hard.
"But there he is again, swimming round and beating the water." "Why, Mark, can't you see that the water there is alive with sharks, and that they are devouring their wounded brother--fighting for the choice morsels, I dare say.

This is a warning never to bathe except in some pool." "What! do you think?
Oh, I see now! How horrible!" said Mark.
"Horrible, eh ?" grunted Gregory.

"I wish they'd make a day of it, and eat one another all up.

We could get on very well without sharks." Mark said no more about putting their enemy out of his misery, but sat watching till, at the end of a few minutes, the surface of the lagoon grew calm; but until they had turned a low spit of sand, the black fins of at least a dozen sharks could be seen cruising round and round, and to and fro, in search of something more to satisfy their ravenous hunger.
"We are getting some experience of the dangers we shall have to encounter," said the captain, as the scene of their late conflict with the shark passed completely out of their sight, and they rowed on steadily.
