I have heard of a wonderful ball, which floats in the sweet blue air, and has little soft white clouds about it, as it swims along. It is a very big ball; far bigger than the great soft ball, of bright colors, that little Charley plays with on the floor. . . . Let me tell you about "my" ball. It is so large that trees can grow on it; so large that cattle can graze, and wild beasts roam, upon it; so large that men and women can live on it, and little children too. . . .
