Mabel Lossing Jones, 100, a former missionary teacher for the Methodist Church who spent many years in India, died Thursday at the Asbury Methodist Village Health Center in Gaithersburg.

She had became a resident at the home about four years ago after breaking a hip and being confined to a wheel chair.

Mrs. Jones was the widow of the Rev. E. Stanley Jones, a noted Methodist missionary and evangelist who died in Orlando, Fla., in 1973.

She had grown up in Clayton, Iowa, and her husband grew up in Baltimore. They met and were married in India where they became friends of the Indian pacifist leader Mahatma Gandhi.

Mrs. Jones was principal of a boy's school in Sitapur, where she introduced the use of women teachers in classes for primary school boys in India. She helped keep thousands of Indian boys in school with scholarship funds raised through friends in this country. She also treated thousands of Indians during epidemics and emergencies.

Mrs. Jones came back to this country in 1946 and divided her time between Orlando and Clayton, Iowa.

On her 90th birthday, she received an honorary doctor of human letters degree from her alma mater, Upper Iowa University at Fayette.

On her 100th birthday on April 3, the city of Gaithersburg, also marking its 100th birthday, honored Mrs. Jones with a cake and a plaque.

She is survived by a daughter, Eunice Mathews, wife of United Methodist Bishop James K. Mathews of Washington, three grandchildren and two great-grandchildren.
