He tosses about in every bare tree,
As, if you look up, you plainly may see;
But how he will come, and whither he goes,
There's never a scholar in England knows.
He will suddenly stop in a cunning nook,
And ring a sharp 'larum;—but, if you should look,
There's nothing to see but a cushion of snow
Round as a pillow, and whiter than milk,
And softer than if it were covered with silk.
Sometimes he'll hide in the cave of a rock,
