The Gilchrist reference to Harpers names only the year 1882, not the month. You may have to go through a whole years's worth. There was, I think, a separate European edition, printed in London, at that time; they seem to have had different volume numbers and quite possibly variant content. It isn't clear whether or not Miss Gilchrist was referring to the American or European version, so that adds to the uncertainty! Finally, Shangadore was the name given the song by Henry Burstow (who would only sing one verse to a lady); the name(s) given it in Alden's article may be different.
