As you all know, Peter Rabbit is out and about at a time when most folks are snugly tucked in bed. The fact is, Peter is very fond of roaming around at night. He says he feels safer then in spite of the fact that some of his smartest enemies are also out and about, among them Hooty the Owl and Reddy Fox and Old Man Coyote. The two latter also hunt by day when the fancy takes them or they have been so unsuccessful at night that their stomachs won't give them any peace, and Peter is sure that though they can see very well at night, they can see still better in the light of day. Anyway, that is one of the reasons he gives for his own liking for roaming after jolly, round, red Mr. Sun has gone to bed behind the Purple Hills.  
Now it happened one moonlight night that Peter had ventured way over almost to the Big River. He had heard Hooty the Owl's fierce hunting call far off in the Green Forest. He had heard Reddy Fox barking up in the Old Pasture. So Peter felt quite safe. He felt so safe that he had almost forgotten that there could be such a thing as fear. And then, from the direction of the Big River, there came such a sound as Peter never had heard before. It was a sound that made his heart seem to quite stop beating for an instant. It was a sound that sent cold chills racing and chasing all over him. It was a sound that made him wish with all his might that he was that instant right in the heart of the dear Old Briar-patch instead of way over there near the bank of the Big River.
 
He didn't waste much time getting back to the dear Old Briar-patch, once he was sure his heart hadn't really stopped beating. The way he went across the Green Meadows, lipperty-lipperty-lip, lipperty-lipperty-lip, was positive proof that in spite of his fright his heart was quite all right. He didn't run a little way, stop, run a little farther and stop again, as is his usual way. He kept lipperty-lipperty-lipping without a single stop until he reached the edge of the dear Old Briar-patch and once more felt really safe. Two or three times he had felt that he must stop to get his breath, but each time that sound, that dreadful sound, had seemed to be following right at his heels, and he had suddenly discovered that he didn't need to stop after all.
 
But having reached the dear Old Briar-patch Peter stopped and panted for breath while he anxiously watched for the appearance of some unknown enemy following him. It was then that he realized that that sound came from the Big River, and that whoever made it had not left the Big River at all. It made Peter feel a wee bit foolish as he thought how he had been sure that there was danger right at his very heels all the way home, when all the time there hadn't been any danger at all.
 
Peter sat there and listened, and despite the fact that he now felt absolutely safe, the cold chills ran over him every time he heard it. It was a voice; Peter was sure of that. It was a voice, but such a voice as Peter never in his life had heard before. It was quite as bad if not worse than the voice of Old Man Coyote. In a way it reminded him of Old Man Coyote's voice, but while Old Man Coyote's voice sounded like many voices in one, it was not so fearsome as this voice, for this voice sounded like a human voice, yet wasn't. Something inside Peter told him that it wasn't a human voice, in spite of its sounding so.
 
The next morning Peter ran over to the Smiling Pool to ask Grandfather Frog if he had any idea who could have such a voice as that. When he tried to tell Grandfather Frog what that voice was like, he couldn't. He just couldn't describe it.
 
"It was the lonesomest and craziest sound I've ever heard," declared Peter, "and that is all I can tell you. It was crazier than the voice of Old Man Coyote."
 
"That is all you need tell me," chuckled Grandfather Frog. "That was the voice of Dippy the Loon. And let me tell you something, Peter: you are not the first one to think his voice has a crazy sound. Oh, my, no! No, indeed! Why, a lot of people think Dippy is crazy, and when any one does queer things they say of him that he is 'crazy as a Loon.'
 
"But is he crazy?" asked Peter.
 
"Chug-a-rum!" exclaimed Grandfather Frog. "Chug-a-rum! Not half so crazy as you are, Peter, coming over here to the Smiling Pool in broad daylight. He likes to be thought crazy, just as his great-great-ever-so-great-grandfather did before him, that's all. Everybody thought his great-great-ever-so-great-grandfather was crazy, and it paid Mr. Loon to have them think so. So he did his best to make them keep thinking so."
 
"Tell me about it. Do please tell me about it, Grandfather Frog," begged Peter. "Please, please, please."
 
Now how could Grandfather Frog resist that? He couldn't. He didn't even try............
