How can I quote a favourite when every definition in the book (300 pages or so) is a gem?. But I'll just cite:
CHRISTIAN: one who believes that the New Testament is a divinely inspired book admirably suited to the spiritual needs of his neighbor.
NEIGHBOR: One whom we are commanded to love as ourselves, and who does all he knows how to make us disobedient.
POCKET: the cradle of motive and the grave of conscience.
RETALIATION: The natural rock upon which is reared the Temple of Law.
KING: A male person commonly known in America as a crowned head, although he never wear a crown and has usually no head to speak of.
DICE: Small polka-dotted cubes of ivory, constructed like a lawyer to lie on any side but commonly on the wrong one.
Then there are the stories and verses that illustrate some of the definitions.
Anyone who doesn't know the work can find it on a variety of websites including www.paganlibrary.com. And on the Project Gutenberg site you can find his "Fantastic Fables".
