Mabel Cary Scholtz, 95 who with her husband had raised thoroughbred race horses and purebred Hereford cattle on their farms at Warrenton, Va., died of pneumonia Monday at Fauquier Hospital in Warrenton.

She was the widow of retired Army Maj. Herman F. Scholtz, who died in 1973. They had maintained Woodbourne and Riverland farms for many years. Mrs. Scholtz was still living at Woodbourne at the time of her death.

She was born in Stillwater, N.Y., and studied voice at the Master School of Music in New York City under Ernestine Schuman-Heink. She married Maj. Scholtz in 1908.

From the end of World War I until 1942, they lived in Bangkok, Thailand, where Maj. Scholtz was president of the International Engineering Co., Ltd. When the Japanese invaded Thailand, they were interned in a prisoner-of-war camp.

The Scholtzes were among those who were returned to this country on the first trip of the repatriation liner, Grispsholm, in 1942. They then acquired their farms at Warrenton.

Mrs. Scholtz had been an active member of the Colonial Dames of America, the Women's Club of Washington, the Bangkok-Washington, D.C., Society, the Warrenton Garden Club, the Garden Club of Virginia, the Antiquarian Society of Warrenton and St. James Episcopal Church in Warrenton.

She is survived by a sister, Agnes Cary Gardenier, of Melrose, N.Y.

It is suggested that expressions of sympathy be in the form of contributions to the Warrenton Rescue Squad.
