According to a website I found for the book and author you mentioned, it is based on Child Ballad No. 1, which is called Riddles Wisely Expounded, but for the life of me, I cannot find that Child Ballad at any of the sites I know of.

If someone doesn't wander in here and know it, you might want to start a new thread with the title of the ballad and/ Child Ballad No. 1, in the title of the thread.

I'll keep looking, too.
