Down by the sea, farther to the west, a young squirrel was skipping aimlessly about in the snow. He was quite a foolish little squirrel who liked to think of himself as “the squirrel with the marvelous tail.”
  As a matter of fact, he never though about anything for very long. Mostly he just had a feeling about things. His latest feelings was that his mattress in the nest was getting knobbly, so he had gone out to look for a new one.
  Now and again he mumbled: “A mattress,” to keep himself from forgetting what he was looking for. He forgot things very easily.
