The Chums of Scranton High on the Cinder Path / Or, The Mystery of the Haunted Quarry

A tight-knit group of five high-school friends stage outdoor exploits and investigations when strange happenings at a nearby quarry and an intruder stir suspicion; they split between training for athletic contests and sleuthing, confronting pranks, betrayal, and ghostly rumors while mounting rescue efforts, organizing searches, and exposing a prowler. Episodes include preparations for a major tournament, an open-house day, persistent physical challenges culminating in an intense marathon, and personal reckonings that test loyalty and character. The narrative emphasizes teamwork, courage, resourcefulness, and the rivalry and sportsmanship that shape the boys' coming-of-age adventures.
