The Broncho Rider Boys on the Wyoming Trail Or, A Mystery of the Prairie Stampede

A band of hard‑working bronco riders pushes toward the open plains of Wyoming, leaving the Arizona border behind. Led by the quick‑witted Adrian and his steadfast friend Billie, they share long nights on the trail, swapping jokes about stubborn horses and the endless stretch of sky. Their trusty mount Jupiter, once a source of constant danger, now settles into a steady rhythm, hinting that even the wild can be tamed with patience.

As the convoy nears the cattle country, the men sense that something is amiss among the rolling grasslands. Rumors of a mysterious stampede begin to surface, and the boys find themselves drawn into a puzzle that could endanger the entire herd. Their bond, humor, and daring horsemanship will be tested as they race to uncover the truth before the prairie’s silence is broken for good.
