One day a fellow who had been unfortunate in turtle hunting, and taken nothing for a fortnight, determined to follow the chief, and find out where he had so much good luck. He paddled his canoe silently along, keeping some distance in the rear, so that he was not noticed by the lover. The latter reached the cave, and was so intent on seeing his lady love that he did not think to look around. Taking a bag of cocoa-nuts, he dived and rose as usual. The other waited a long time for his reappearance, and at last was rewarded by seeing him come up dragging a turtle, which he lifted into the canoe. Just as he was picking up his paddle, he discovered the spy, and knew that his secret, or at least a part of it, had been found out. [Sidenote: FATE OF A SPY.] The other laughed, but his laugh was brief, as the lover went for him, and there was every promise of a fight. The canoes met with a crash, and the men grappled and fell into the water. Their struggle was long, as neither had any weapons or clothing, and their oily skins did not offer good holding-ground for their hands. At last the chief had the spy by the throat, and at the same time struck him a violent blow on the nose, so that the blood spurted out. The waters of the South Pacific swarm with sharks. Some of these grow to a considerable size, and are strong enough to seize a man and kill him. They rarely attack the natives; there seems to be a friendliness among the sharks and the natives, as the latter can swim among them with almost complete safety, while a white man would be caught in a moment. It sometimes happens that a group of natives will be bathing and frolicking in the water with sharks all around, as inattentive as though nothing were near them. But let a white man join the party, and he will instantly attract the sharks. A white cloth thrown into the water will bring them around; anything white seems to draw them and receive their attention. It not unfrequently happens that sailors who have incautiously put their naked hands or feet into the water over the sides of a boat have had them bitten off by sharks. [Sidenote: FOOD FOR SHARKS.] Blood also attracts them, and where there is blood, they make no distinction between natives and foreigners. In the present instance, the lover had drawn blood from his antagonist, and it instantly occurred to him that both their lives were in danger if any sharks were around. He released his hold, dived under his canoe, and swam away a hundred feet or more, so as to be out of the vicinity of the blood he had drawn.
