A Cure for the Blues is a classic satirical work by Mark Twain. By courtesy of Mr. Cable I came into possession of a singular book eight or ten years ago. It is likely that mine is now the only copy in existence. Its title-page, unabbreviated, reads as follows: "The Enemy Conquered; or, Love Triumphant. By G. Ragsdale McClintock, [1] author of 'An Address, ' etc., delivered at Sunflower Hill, South Carolina, and member of the Yale Law School. New Haven: published by T. H. Pease, 83 Chapel Street, 1845."
