Specter Moose Haunts the Woods
In Curtis D. MacDougall's 1940 book, Hoaxes, one of the early chapters is called "Why We Don't Disbelieve." In that chapter, brief mention is made, under the heading of "recent additions to unnatural history, all of which received space on press association wires", of "a 'specter moose' reported to have appeared again in the woods of Maine after having previously been seen in 1901, 1917, and 1932."
Well, there's another item to add to my list of research treasure hunts in the old newspaper files...
