In 1876, Roderick Ross, one of Florence's first blacksmiths, constructed this Sonoran-style adobe house. Its original flat earthen roof, made of round log beams, saguaro ribs, and mud, is well preserved by a gable roof added between 1899 and 1910. Turned-wood posts support a timber-framed, hip-roof veranda. W.C. Smith was the second owner. Pauline Cushman, a celebrated Union spy, and her husband, Jere Fryer, later purchased the house. Tom Mix was a tenant here in the 1930s. It is listed on the National Register of Historic Places.
