[4] Mary Jane Scott Farnham died in Shanghai, China, February 22, 1913.

After many years at the South Gate, Dr. and Mrs. Farnham moved to the Hong Kew section of the Foreign Settlement, which they made the center of their work in helping the Chinese churches which were growing up, and where their home opened its generous hospitality to all and where Mrs. Farnham's kind and friendly spirit brought good cheer to the Chinese, to the missionaries and to foreign visitors.

The Board voted to record its grateful acknowledgment of her long and loving service and to express its affectionate sympathy with Dr. Farnham, and to assure him of its prayer that his remaining years might be filled with blessing as the years that had gone before when he and Mrs. Farnham wrought together.In 1913, Rev.

Farnham published A Devoted Life, a compilation in memory of his wife, containing memorial notices, letters of condolences from missionaries and friends in China, England, the U.S., some verses written by Mrs. Farnham, and her music to "The Radiant Morn Has Passed Away".
