It chanced that his friends, the other boys, were farther out than the men; having, with the ardor of youth, engaged themselves in races, regardless of the admonition that had frequently been given them to keep near the ship; for the terror of these water beasts was very great.

The men all gained the ship in safety, but the shark, which had come up from a direction in which it would cut them off, was clearly likely to arrive before the boys could gain the side. At first it seemed, indeed, that their fate was sealed; but the shark, who in many respects resembles a cat with a mouse, and seems to prefer to trifle with its victim to the last, allowed them to get close to the ship; although, by rapid swimming, it could easily have seized them before.

The nearest to it, as it approached the ship, was Tom Tressilis, who was not so good a swimmer as the others; but he had swum lustily, and with good heart, though his white face showed how great the effect of the danger was upon him. He had not spoken a word, since the shark first made its appearance. As he struck despairingly to gain the ship, from which the sailors were already casting him ropes, his eye caught that of Ned, who cried to him cheerily:

"Keep up your spirits, Tom. I will be with you."

As the huge fish swept along, at a distance of some four yards from the side of the ship, and was already turning on its back, opening its huge mouth to seize its victim, Ned dived head foremost from the ship onto him. So great was the force and impetus with which he struck the creature, that it was fairly driven sideways from its course, missing by the nearest shave the leg of Tom Tressilis. Ned himself was half stunned by the force with which his head had struck the fish, for a shark is not so soft a creature to jump against as he had imagined; however, he retained consciousness enough to grasp at the fin of the shark, to which he held on for half a minute.

By this time the shark was recovering from the effects of the sudden blow, and Ned was beginning to be able to reflect. In a moment he plunged the half pike deep into the creature's stomach. Again and again he repeated the stroke; until the shark, rolling over in his agony, and striking furiously with his tail, shook Ned from his hold. He instantly dived beneath the water, and came up at a short distance. The shark was still striking the water furiously, the sailors on board were throwing down upon him shot, pieces of iron, and all sorts of missiles, and some of the best archers were hastily bringing their bows to the side.

The shark caught sight of his opponent, and instantly rushed at him. Ned again dived, just before the creature reached him; and, rising under him, inflicted some more stabs with the pike; then he again swam off, for he was in no slight fear that he might be struck by his friends on board ship, of whose missiles, indeed, he was more in dread than of the shark himself.

When he rose, at a short distance from the shark, he was again prepared for a rush on the part of his enemy; but the great fish had now had enough of it. He was still striking the water, but his movements were becoming slower, for he was weakened by the loss of blood from the stabs he had received from below, and from the arrows, many of which were now buried to the goose quill in him. In a minute or two he gradually turned on one side, and floated, with his white belly in the air.

A shout broke from the crew of the Swanne, and also of the Pacha, who had been attracted to the side by the cries. When he saw that the battle was over, and that the enemy had been vanquished without loss of life, or hurt to any, Ned speedily seized one of the ropes, and climbed up the side of the ship; where he was, you may be sure, received with great cheering, and shouts of joy and approval.

"You are a fine lad," Captain John Drake said, "and your name of Otter has indeed been well bestowed. You have saved the life of your comrade; and I know that my old friend, Mr. Frank Tressilis, his father, will feel indebted indeed to you, when he comes to learn how gallantly you risked your life to preserve that of his son."
