When you reach that, you must turn to your right and go toward Hoods' until you come to the pawpaw thicket.
Go around that, look ahead, and you'll see the biggest beech tree you ever saw.

You know a beech, don't you ?" "Of course I do," I said indignantly.

"Father taught me beech with the other trees." "Well then," said Laddie, "straight before you will be a purple beech, and under it is the throne of the Princess, the Magic Carpet, and the walls I made.

Among the beech roots there is a stone hidden with moss.
Roll the stone back and there will be a piece of bark.

Lift that, lay the letter in the box you'll find, and scamper to me like flying.
