At the age of 18, Mace published her best-known hymn, "Only Waiting till the shadows" in the
Waterville, Maine Mail, under the signature "Inez", the text of which was developed after a friend's recital of the story of a very aged man at the alms-house, who, being asked what he was doing now, replied, "Only waiting!" Her hymn became popular in the United States and Britain, and its authorship was disputed, by a certain U.S. woman, whose right for a time was almost unquestioned. In 1878, 25 years after its first appearance, full proofs of Mace's authorship were accepted by Dr. James Martineau. In 1855, she married Benjamin F. Mace, a lawyer of Bangor, remaining in that city until 1885, when they removed to
San Jose, California, residing at Palmtree Lodge. Four of her eight children died young. After the eighth child turned two, she began writing again after a quiet period of about 20 years. "Israfil" appeared, with illustrations, in ''Harper's Magazine
, gaining for her quick recognition and advancing her toward the front rank of singers. After that, her poems found place in the leading magazines and journals, including Century
, Atlantic
, and Lippincott's''. In 1883, she published a collection of poems in a volume entitled
Legends, Lyrics and Sonnets, soon followed by a second edition, enlarged and extended. In 1888, a volume of work was published with the title
Under Pine and Palm, adding to her reputation. ==Death==
