Once upon a time, not so very many years ago, there lived three ducks in a duck pen. And this pen was not far from where Sammie and Susie Littletail, the rabbit children, had their burrow, and it was close to the trees where Johnnie and Billie Bushytail, the squirrel brothers, learned to jump from their nest. Now I am going to tell you some stories about these ducks, and what they did. To begin with there was the mamma duck. She was Mrs. Wibblewobble, a nice, white duck, being a cousin to Mrs. Quack-Quack, who once rescued Billie and Johnnie Bushytail, and Jennie Chipmunk from the desert island where they had been shipwrecked, you remember.
