In 1927 Donald Pharis purchased a 160-acre farm in rural Clay County and gave up teaching to farm full time. As a farmer he continued to teach about the importance of soil and water conservation. He was the first farmer in Clay County to terrace his fields. He was a founding member of the Clay County Soil & Water Conservation District and assisted farmers throughout the Midwest. Donald and his second wife, Laura welcomed students to their farm and taught them about historical and modern farming practices, the importance of soil and water conservation, and pioneer life. Today, visitors can tour the farm during special events.
