Three doctors worked the same eleven rooms in Lincoln, one after another, from 1936 to 1973: house, office, and a four-bed clinic under one roof. The Arkansas Country Doctor Museum is that building, opened as itself rather than as an exhibit about rural medicine. On the clinic side there is an iron lung to stand in front of, surgical tools that went onto Civil War battlefields, and the instruments of early optometry. In the living quarters the Boyers' own mid-century furnishings are still in place, women's hats, china plates, and a long run of salt-and-pepper shakers among them. Out in the carriage house an 1886 Studebaker buggy that a country doctor drove on house calls until 1920 sits beside a 1924 Model T Roadster, and a medicinal herb garden grows on the grounds. Dr. Harold Boyer established the museum in 1994 for his father, Dr. Herbert Boyer, the last physician to practice here, and the person who walks you through is a volunteer; by the museum's own account, many of them knew this kind of care from the inside. Go for the house rather than for any one object in it, and give it an afternoon, because that is what the door offers: 1 to 4 p.m., Wednesday through Saturday, closed November through February. On the western edge of Washington County.
