From the crest of a wave on which he struck, Frank turned to look at the whale and see what had become of his companions. The monster was bringing his tail into play now. With one fierce upward sweep of his huge flukes he lifted the battered boat out of the water, and the captain, who had clung to the wreck, was going up with it. The air seemed to be literally filled with pieces of planks, harpoons, ropes and lances. The crew had all escaped without injury—at least they were all able to swim, for Frank counted four frightened faces bobbing about on the waves near him. He had some idea now of the strength and ferocity a whale could display when he once set about it. He made up his mind, too, that men must be simply foolhardy to willingly follow any such business as whaling. Otherwise how could they bring themselves to engage with such a monster as this, against whose tremendous power, which he had just seen exerted with such telling effect, their strength was as nothing?

To say that Frank was frightened would not begin to tell how he felt. How helpless he was! How completely the waves baffled his mad efforts to get out of the reach of his dangerous foe, and how like straws they seemed in the path of the whale which skimmed through them as easily as a bird passes through the air! Then how frightened everybody else was, if he might judge by the pale faces he saw about him, and the frantic attempts the men made to swim away. If those who were accustomed to such scenes and such dangers were so nearly overcome with terror, it was time for a novice to show signs of fear.

"Look out, Nelson!" cried Lucas, suddenly. "Look out! He's——"

The old boatswain's mate no doubt meant to say something else, but he did not stay on top of the water long enough to say it. He ducked his head and went down like lead, making desperate struggles to go faster. Frank cast one frightened glance over his shoulder and went down too. The whale had turned again and was coming directly toward him, rolling from side to side and slashing from right to left with his jaw, describing at each stroke a circle thirty-two feet in diameter. There was no time to swim out of his reach. His only chance for life was to go below him. How Frank blessed his lucky stars at that moment that deep diving and swimming long distances under water were two of his accomplishments! He went as far down as he could, stayed under as long as he could hold his breath, and came up almost strangled. He was out of danger. The battered boat was twenty feet away and the whale a hundred feet still farther off, and moving rapidly toward the ship. The men were all clinging to the boat to keep themselves afloat, and Frank swam up and joined them.

All this while the men in the mate's boat had been doing their best with sail and oars to get near enough to the whale to take part in the fight, but without success. Now, however, they had an opportunity offered them, for the whale had doubled on his course, and if he did not take it into his head to turn again, he would pass their boat at such a distance that they would have a chance at him with their harpoons. The mate prepared for it by ordering one man to take down the sail while the rest still tugged at the oars. He did not even look toward the disabled boat or ask if the crew wanted assistance.

"These whalemen are a heartless lot," thought Frank. "If I were in command of that boat I think I should save my shipmates first; but I suppose that officer thinks we are not worth as much as the whale. Men can be had any day for the asking, and if a few of them lose their lives what's the odds? Nobody misses them. But whales are not as plenty as they used to be, and if one of them is lost it is something to be sorry for."

Frank's meditations were interrupted and his attention called from the chase by the actions of one the men near him, who suddenly began to make desperate efforts to climb into the boat. He persisted in spite of the angry orders and oaths of the skipper, who stormed and threatened to no purpose. The man was almost beside himself with fear.

"What has come over him all at once?" asked Frank, of the man at his side. "He was quiet enough a moment ago."

"He had a narrow escape from a shark once," replied the sailor, "and I guess he has just thought of it."

"Well, I wish from the bottom of my heart that he hadn't thought of it at all," said Frank, "or else that I had not asked you any questions, for I have new cause for alarm now. I wonder if a sailor can turn in any direction without finding himself confronted by some deadly peril?"
