Kathleen B. Walsh, 67, a former Agriculture Department employe and a longtime Washington area resident, died of cancer Sunday at the National Naval Medical Center in Bethesda.

Mrs. Walsh was born in Goldston, N.C., and reared in Durham, N.C. She attended Duke University for about three years before moving to this area in 1934 to work for the Agriculture Department. She was secretary to the director of the department's Soil Conservation Service for several years before quitting work to devote time to her family.

Although she and her husband, retired Marine Col. Walter R. Walsh, had maintained a home in Arlington for the last 43 years, Mrs. Walsh had accompanied her husband to several military posts in this country.

Mrs. Walsh was a member of the Duke University Alumni Association and St. Ann's Catholic Church in Arlington.

Besides her husband, survivors include three daughters, Kathleen Reams of Silver Spring, Linda Lee Wells of Arlington, and Rosemary Haas of Orchard Lake, Mich.; two sons, Walter of Birmingham, Ala., and Gerald of McDonough, Ga.; a brother, Herbert Barber, and a sister, Myra Morgan, both of Durham; another sister, Doris Stocking of Arlington, and 12 grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the American Cancer Society.
