A House-Boat on the Styx

<br> "When the Associated Shades, comprising such notables as Dr. Johnson [... several others listed], established a club in a house-boat on the Styx, and installed Charon as janitor, their meetings naturally were occasions of unusual interest; and remarkable sagacity has been displayed in the selection of Mr. Bangs as the medium for the publication, above ground, of their sayings and doings." -- advertisement by the publisher, <i>New-York Tribune</i> 1895-11-27 p8 "Published To-day"

First published as a serial in 12 parts (one chapter per issue with a skip; including the Peter Newell illustrations, uncredited, commonly signed). Harper's Weekly vol. 39, #2017-2029; August 17 to November 9, 1895; page-span p780 to p1065.   All but the final instalment appear under 6-line headings that begin with these three lines in diminishing typographical emphasis: A House-Boat on the Styx. Being some account of the divers doings of the associated shades. (Publication Authorized by the House Committee.) followed by the by-line, a horizontal line, and a roman numeral chapter number with chapter title. So these three lines may be interpreted as a three-part full title.
