"So that the fish wouldn't see him coming?" asked Mr. Steele. "Well, Jacob, to tell you the truth, I never thought much about it. And I don't really know how a shark would look from underneath, in the water. The pearl divers in India could tell you. But I guess that comes as near to the reason as any other—near enough, anyway. I've no doubt that his coloring makes him very hard to see, in the water."

"I would like to see the pearl divers," said little Jacob, "but I s'pose I can't. And I'm rather glad the shark is gone."

"Huh!" said little Sol. "He isn't gone. He only stopped a minute. He'll be back. Won't he, Mr. Steele?"

Mr. Steele smiled. "There he comes, now."

And the boys looked and they saw the three-cornered fin cutting through the water at a great rate. The shark caught up with the ship easily and took his old place, just astern.

The shark stayed with the Industry all of that day, and little Jacob watched him once in a while. He thought the shark was kind of horrible and he wished that he would go away. But he didn't, that day or that night, or the next. And Captain Solomon didn't like it, either.

So, when Captain Solomon saw him on the third morning, he spoke to the mate.

"Better get rid of that fellow, Mr. Steele," he said. "Got a shark hook?"

"Yes, sir," answered the mate. "But I'm afraid it isn't big enough for him."
