Peter was suddenly reminded of Rattles the Kingfisher, whom he had quite forgotten. From the Big Hickory-tree on the bank, Rattles flew out over the Smiling Pool, hovered for an instant, then plunged down head-first. There was a splash, and a second later Rattles was in the air again, shaking the water from him in a silver spray. In his long, stout, black bill was a little fish. He flew back to a branch of the Big Hickory-tree that hung out over the water and thumped the fish against the branch until it was dead. Then he turned it about so he could swallow it head-first. It was a big fish for the size of the fisherman and he had a dreadful time getting it down. But at last it was down, and Rattles set himself to watch for another. The sun shone full on him, and Peter gave a little gasp of surprise.

“I never knew before how handsome Rattles is,” thought Peter. He was about the size of Yellow Wing the Flicker, but his head made him look bigger than he really was. You see, the feathers on top of his head stood up in a crest, as if they had been brushed the wrong way. His head, back, wings and tail were a bluish-gray. His throat was white and he wore a white collar. In front of each eye was a little white spot. Across his breast was a belt of bluish-gray, and underneath he was white. There were tiny spots of white on his wings, and his tail was spotted with white. His bill was black and, like that of Longlegs, was long, and stout, and sharp. It looked almost too big for his size.

Presently Rattles flew out and plunged into the Smiling Pool again, this time, very near to where Longlegs was patiently waiting. He caught a fish, for it is not often that Rattles misses. It was smaller than the first one Peter had seen him catch, and this time as soon as he got back to the Big Hickory-tree, he swallowed it without thumping it against the branch. As for Longlegs, he looked thoroughly put out. For a moment or two he stood glaring angrily up at Rattles. You see, when Rattles had plunged so close to Longlegs he had frightened all the fish. Finally Longlegs seemed to make up his mind that there was room for but one fisherman at a time at the Smiling Pool. Spreading his great wings, folding his long neck back on his shoulders, and dragging his long legs out behind him, he flew heavily away in the direction of the Big River.

Rattles remained long enough to catch another little fish, and then with a harsh rattle flew off down the Laughing Brook. “I would know him anywhere by that rattle,” thought Peter. “There isn't any one who can make a noise anything like it. I wonder where he has gone to now. He must have a nest, but I haven't the least idea what kind of a nest he builds. Hello! There's Grandfather Frog over on his green lily pad. Perhaps he can tell me.”

So Peter hopped along until he was near enough to talk to Grandfather Frog. “What kind of a nest does Rattles the Kingfisher build?” repeated Grandfather Frog. “Chug-arum, Peter Rabbit! I thought everybody knew that Rattles doesn't build a nest. At least I wouldn't call it a nest. He lives in a hole in the ground.”

“What!” cried Peter, and looked as if he couldn't believe his own ears.

Grandfather Frog grinned and his goggly eyes twinkled. “Yes,” said he, “Rattles lives in a hole in the ground.”

“But—but—but what kind of a hole?” stammered Peter.

“Just plain hole,” retorted Grandfather Frog, grinning more broadly than ever. Then seeing how perplexed and puzzled Peter looked, he went on to explain. “He usually picks out a high gravelly bank close to the water and digs a hole straight in just a little way from the top. He makes it just big enough for himself and Mrs. Rattles to go in and out of comfortably, and he digs it straight in for several feet. I'm told that at the end of it he makes a sort of bedroom, because he usually has a good-sized family.”

“Do you mean to say that he digs it himself?” asked Peter.
