Who is the great Unknown? — I've heard, And I believe, Sir WALTER SCOTT; What, that wise, wonder-working Bard, Who wrote about your one-pound note? The same, but now th' unknown no more, How shall we style this Rhetorician? Alike in taste, in tact, and lore, Suppose we dub him the Magician, Who, with his incantations strange, His wizard wand, and mystic rounds, Can one Napoleon quickly change To twenty thousand sterling Pounds!
