" Trust the Oak,” said she; “trust the Oak, and the Elm, and the great Beech. Take care of the Birch, for though she is honest, she is too young not to be changeable. But shun the Ash and the Alder; for the Ash is an ogre,—you will know him by his thick fingers; and the Alder will smother you with her web of hair, if you let her near you at night. "
