Even in this moment of peril, the discipline of the navy assumed its command. At the order from the lieutenant for the men on the keel to relinquish their position they instantly obeyed, the boat was turned over and once more the expedient was tried--but quite in vain; for no sooner had the two men begun to bail with a couple of hats, and the safety of the crew to appear within the bounds of probability, than one man declared he saw the fin of a shark. No language can convey an idea of the panic which seized the struggling seamen; a shark is at all times an object of horror to a sailor; and those who have seen the destructive jaws of this voracious fish, and their immense and almost incredible power--their love of blood and their bold daring to obtain it, alone can form an idea of the sensations produced in a swimmer by the cry of "a shark! a shark!" Every man now struggled to obtain a moment's safety. Well they knew that one drop of blood would have been scented by the everlasting pilot-fish, the jackalls of the shark; and that their destruction was inevitable, if one only of these monsters should discover this rich repast, or be led to its food by the little rapid hunter of its prey.--All discipline was now unavailing, the boat again turned keel up; one man only gained his security to be pushed from it by others and thus their strength begun to fail from long continued exertion. However, as the enemy so much dreaded did not make its appearance, Smith once more urged them to endeavor to save themselves by the only means left, that of the boat; but as he knew that he would only increase their alarm by endeavoring to persuade them that sharks did not abound in these parts, he used the wisest plan of desiring those who held on by the gun-wale, to keep splashing in the water with their legs, in order to frighten the monsters at which they were so alarmed. Once more had hope began to dawn:--the boat was clear to her thwarts, and four men were in her hard at work; a little forbearance and a little obedience, and they were safe. At this moment, when those in the water urged their messmates in the boat to continue bailing with unremitted exertion, a noise was heard close to them, and about fifteen sharks came right in amongst them. The panic was ten times more dreadful than before; the boat was again upset by the simultaneous endeavor to escape the danger; and the twenty-two sailors were again devoted to destruction.--At first the sharks did not seem inclined to seize their prey, but swam in amongst the men, playing in the water, sometimes leaping about and rubbing against their victims. This was of short duration, a loud shriek from one of the men announced his sudden pain; a shark had seized him by the leg, and severed it entirely from the body. No sooner had the blood been tasted than the long dreaded attack took place; another and another shriek proclaimed a loss of limbs; some were torn from the
