Prickly Porky in "Ryder Has To Tell His Story Many Times"

That is the reason why you should always be sure that a story you repeat is a good story. Then you will be glad to have it travel on and on and on, and will never want to call it back. But if you tell a story that isn't true or nice, the time is almost sure to come when you will want to call it back and cannot. You see stories are just like rivers,—they run on and on forever. Little Mrs. Ryder Rabbit knew this, and that is why she advised Ryder not to tell any one else the strange story he had told her of the dreadful creature without legs or head or tail that had chased him in the Green Forest.
