Howard W. Toone, 64, a retired Postal Service employe and a former gas station owner, died at Providence Hospital in Washington Sept. 4 of renal failure and Raynaud's disease, a disorder of the arteries.

Mr. Toone, who was born in Philadelphia and grew up in Arlington, attended Washington-Lee High School. He worked at the Washington Navy Yard and at the Arlington Post Office before enlisting in the Navy during World War II.

He was stationed at the U.S. Embassy in London, where he helped establish "V-mail" service between Europe and the United States.

He returned to the Post Office Department after the war. From about 1948 to 1958, he owned and operated Garry's Service station on Glebe Road in Arlington. He then returned to the Post Office and was an airmail sorter at Dulles Airport when he retired in 1977 for reasons of health.

Mr. Toone, who lived in Lovettsville, Va., was a member of the Cherrydale Methodist Church in Arlington.

Survivors include his wife of 34 years, Doris, of Lovettsville; a son, Garry, also of Lovettsville; his mother, Helen M. Toone of Arlington, and two sisters, Dorothy Van Vladricken of Falls Church and Virginia E. Goff of Arlington.

The family suggests that expressions of sympathy be in the form of contributions to the Loudoun County Humane Society, Hamilton, Va.
