On and on he went until hunger made him look about for a victim. He was not particular as to who or what this creature might be, for his own powers produced an apathy of fear for all dangerous denizens of the deep. He was changing now, and no longer shunned a conflict with anything that formerly might have wounded his soft sides.

One day a whale passed in his wake. The huge bulk of the creature might have appalled any fish, but he was hungry, and the fat blubber was tempting. His own three fathoms of lean, hard flank seemed meager enough.

With a quick movement he turned and made straight for the cachalot. The monster opened his mouth by dropping his long, thin under jaw, and made a chop at him, but he swerved and sank his triangles deep in the blubber of the animal’s neck, covering a good hundred pounds of him.

The whale plunged wildly, lashing right and left with his powerful tail, finally throwing himself clear of the sea and falling again with a stupendous crash. But the shark held grimly on. Rolling over and over the animal tried to throw himself clear of that grip. The blubber was tearing out in a huge ribbon where the triangles had cut it clear, and the blood was showing upon the white fat. The sea was a surf upon a submerged reef. And all the time the shark jerked and wrenched, dodged and pulled until the huge mouthful came clear.

Quickly the whale turned to chop with that long jaw studded with huge points of ivory. Quicker still slewed the shark. The whale missed, and the shark again sank those terrible cutters deep in the hole already made in the animal’s neck. This time it was flesh that felt the bite, and the pain maddened the leviathan. With a bellow like a bull he started off, dragging the shark along with him as though he had been but a tiny pilot fish.

On and on the great whale tore, while the shark hung helpless by his side. The whale was doing all the work, and all he had to do was to hold on. Gradually the pace eased a little, and finally stopped. Then down, straight down into the abyss below, plunged the leviathan.

But even here the shark still held his grip. The pressure became enormous in that cold blackness, but he could stand it as well as the monster.

Then, after an hour of twisting and rolling, they came quickly to the surface again, the whale somewhat tired. Now was the shark’s chance. Letting go his hold he made a sudden fresh chop to tear the bite out, and he backed away with a huge piece of flesh. The whale turned as quickly as possible, but he was tired now, and the shark chopped him again and again, savagely tearing out great pieces of blubber and beef.

The sea was dyed red, and the surging of flukes and threshing about brought several wandering sharks from the depth to see what it all meant. One of these, a huge killer, joined the fight against the whale, and soon he also chopped and tore the wound into a great hole. The fight now became general, as the strangers took a hand. The worried whale rolled and smote right and left, but our shark tore him deeper and deeper.

One of the newcomers ventured across the whale’s head, and was promptly seized in the long thin jaw that swung up and cut him in halves. All except the first assailant left the whale to eat the unfortunate shark, and the two fighters were alone again for some minutes.
