Witnesses saw odd lights in an old and isolated schoolhouse in Emerson, Manitoba. Citizens assumed ghosts. The theory that it was spirits was not entirely wrong.
The lights were from nightly sessions of making moonshine (“and not the Sir Oliver Lodge variety”). “On the teacher’s platform,” The Star Press reported, “they [the police] found a huge still, with a capacity of forty-five to sixty-five gallons daily.”
