Imported to US. H. D. Brown established one of the most sensational Thoroughbred nurseries since the days of Haggin`s Rancho del Paso, Brown`s Shasta Farm. Built in the shadow of Mt. Shasta, it exemplified the benefits of raising Thoroughbreds in high mountainous terrain. Tracer and Bistouri, a pair of grandsons of the influential Rock Sand, stood at Brown`s facility, and both became outstanding sires during the Depression.
