Into the water he cast his bent pin hook, with the fluttering rag for bait. No one saw him, everyone else being at the seal-pool. Sue watched her brother eagerly. She wanted him to hurry, and catch a fish, so they could go over where their mother and Aunt Lu were.

But the fish in the pool did not seem to care for Bunny's rag bait. Perhaps they knew it was only a piece of cloth, and not a nice worm, or piece of meat, such as they would like to eat. Anyhow, they just swam past it in the water.

"Hurry up, Bunny, and catch a fish!" begged Sue. "I want to go and look at the seals."

"All right—I'll have a fish in a minute," Bunny said, hopefully.

But he did not. The fish would not bite. Bunny wanted to catch something, and, all at once, he decided that if he could not get a fish he might get a turtle, or a small alligator. But he did not tell Sue what he was going to do, for he knew she would not like it. She was afraid of alligators and turtles.

Bunny pulled his line from the fish-pool and tossed the pin-hook over into the turtle-pool. And then something happened, all at once! There was a rush through the water, as a big turtle saw the fluttering rag, and the next minute Bunny was nearly pulled over the low railing into the pool. For the turtle had swallowed his bent pin hook.

"Oh, Sue! I've got one! I've got one!" cried Bunny, shouting out loud, he was so excited.

"Have you got a fish, Bunny?" asked Sue, who had walked a little way over toward the seal-pool.

"No, I haven't got a fish, but I've got a turtle. But I won't let him hurt you, Sue!" he called. "Oh, I've got a big one! Look, Sue!"

Bunny was holding tightly to the string. He had wound it about his hands, and as the cord was a strong one, and as the turtle had swallowed the bent-pin hook on the other end, Bunny was almost being pulled over into the tank full of water, where the alligators and other turtles were now swimming about, very much excited, because the turtle which Bunny had caught was making such a fuss.
