John Minninger, who has been serving in the regular U.S. Army for the past three years, arrived home Wednesday night of last week. He has put in three years of faithful service for his country and as a reward received an honorable discharge from the army. He has been stationed in Texas during his entire service and has spent much of the time on the border and has witnessed some exciting times.
