“In a way it is like yours,” replied Old Mother Nature, “but at the same time it is different. In the first place, it goes almost straight down for a long distance. In the second place there is no mound of sand in front of Yap Yap's doorway. Instead of that the doorway is right in the very middle of the mound of sand. One reason for this is that when it does rain out where Yap Yap lives it rains very hard indeed, so that the water stands on the ground for a short time. The ground being flat, a lot of water would run down into Yap Yap's home and make him most uncomfortable if he did not do something to keep it out. So he brings the sand out and piles it all the way around his doorway and presses it down with his nose. In that way he builds up a firm mound which he uses for two purposes; one is to keep the water from running down the hole, and the other is as a sort of watch tower. He sits on the top of his mound to watch for his enemies. His cousins with the white tail digs a hole more like yours. “Yap Yap loves to visit his neighbors and to have them visit him. They are lively little people and do a great deal of talking among themselves. The instant one of them sees an enemy he gives a signal. Then every Prairie Dog scampers for his own hole and dives in head first. Almost at once he pops his head out again to see what the danger may be.” “How can he do that without going clear to the bottom to turn around?” demanded Peter. “I wondered if any of you would think of that question,” chuckled Old Mother Nature. “Just a little way down from the entrance Yap Yap digs a little room at one side of his tunnel. All he has to do is to scramble into that, turn around and then pop his head out. As I said before, his tunnel goes down very deep; then it turns and goes almost equally far underground. Down there he has a nice little bedroom. Sometimes he has more than one.” “If it is so dry out where he lives, how does he get water to drink?” asked Happy Jack. “He doesn't have to drink,” replied Old Mother Nature. “Some folks think that he digs down until he finds water way down underneath, but this isn't so. He doesn't have to have water. He gets all the moisture he needs from the green things he eats.” “I suppose, like the rest of us, he has lots of enemies?” said Peter. Old Mother Nature nodded. “Of course,” said she. “Old Man Coyote and Reddy Fox are very fond of Prairie Dog. So are members of the Hawk family. Then in some places there is a cousin of Shadow the Weasel called the Black-footed Ferret. He is to be feared most of all because he can follow Yap Yap down into his hole. There is a cousin of Hooty the Owl called the Burrowing Owl because it builds its home in a hole in the ground. You are likely to find many Burrowing Owls living in Prairie Dog villages. Also you are apt to find Buzztail the Rattlesnake there.
