Hilda Walker Boice, 85, a retired employe of the old Bureau of Public Roads and a former officer of state and local chapters of the Daughters of the American Revolution, died of congestive heart failure Thursday at Prince George's General Hospital. She lived in Mitchellville, Md.

A native of Mitchellville, Mrs. Boice moved to Washington at an early age and attended public schools here. She was a member for more than 75 years of the Ryland Epworth United Methodist Church in Washington.

In 1918, she went to work for the old Bureau of Public Roads, where she remained until retiring in 1956 as administrative assistant to the bureau's general counsel.

After her marriage in 1949 to Bertram Boice, a Prince George's County tobacco grower, she moved to her husband's tobacco farm in Mitchellville. He died in 1961.

Mrs. Boice was a member of the Prince George's County Chapter of the DAR. She had held every chapter office, including regent and treasurer. She also held DAR state offices, including state correspondent of the D.C. Chapter, and served on a number of DAR national committees.

Survivors include a brother, W. Desmond Walker, and two sisters, Lillias Hamilton and Naomi Walker, all of Mitchellville.

The family suggests that expressions of sympathy be in the form of contributions to the Kate Duncan Smith DAR School, Grant, Ala.
