Biblical law (25th chapter of Book Leviticus) decreed a Jubilee was to be proclaimed every 50 years in order to pardon certain crimes, whereby slaves could be released, a real beacon of hope during slavery days. 1915 was the 50th year since slavery was abolished in the United States, apparantly not celebrated in Alabama, one of the southern states where the 14th amendment didn't seem to count.
