Thanks Lighter, I appreciate your help.
Does your photocopy have the date and page numbers?, and was it the Harpers' American or London edition? Monthly Indexes for the American edition, 1882, do not show an article by Alden.
I would like to add the complete article to my notes, and if it is the American edition, I can copy from the website.

I have been looking for any evidence that the song was known to soldiers of the Civil War, but there seems to be none. That it was a chantey at the time is fairly well-established.
