Working together they edited _Unity Hymns and Chorals_, published in 1880, a revised edition of which appeared in 1911. (J. V. Blake, _q.v._, was also an editor of the first, but not of the revised edition). In 1885 they published a small collection of their poems entitled _The Thought of God in Hymns and Poems_, followed by later collections with the same title, 2^nd Series 1894, 3^rd Series 1918.
