The Schuylkill County Historical Society will present a program on the Pennsylvania German healing practice of pow wow from 6:30 to 7:30 p.m. on Aug. 28 at its headquarters, 305 N. Centre St., Pottsville.

“Porcupine Pat” McKinney will discuss the history and practice of this Bible-based folk medicine, which uses verbal incantations, gestures and manipulation of material objects.

There is an admission charge for anyone who is not a historical society member.
