I was morbidly curious enough to actually go find the 6th edition on open library. The actual definition:
Money. In usual and ordinary acceptation it means coins and paper currency used as a circulating medium of exchange, and does not embrace notes, bonds, evidences of debt, or other personal or real estate. Lane v Railey, 280 KY. 319, 133 S.W.2d 74, 79, 81.
A medium of exchange authorized or adopted by a domestic or foreign government as part of its currency. U.C.C. S 1-201(24).
Neither "sawdust" nor "beaver pellets" appear anywhere in the 1700-page book. Googling that phrase turns up only this very thread.
They seriously believe that the dictionary definition of money is "pellets and sawdust may be money but Federal reserve notes cannot"?
Even aside from the absurdity of it, it refers to itself in the definition. It's a bit like saying the definition of 'milk' is "cow milk is milk, but pineapple juice isn't milk."
