[12] The first of these was Rev. Edward H. Hall's First Lessons on the Bible, which appeared in 1882; and it was soon followed by Professor C.H. Toy's History of the Religion of Israel. [13] Among these were Religions before Christianity, by Professor Charles Carroll Everett, D.D., 1883; Manual of Unitarian Belief, by Rev. James Freeman Clarke, D.D., 1884; Lessons on the Life of St. Paul, by Rev. Edward H. Hall, 1885; Early Hebrew Stories, by Rev. Charles F. Dole, 1886; Hebrew Prophets and Kings, by Rev. Henry G. Spaulding, 1887; The Later Heroes of Israel, by Mr. Spaulding, 1888; Lessons on the Gospel of Luke, by Mr. Spaulding and Rev. W.W. Fenn, 1889; A Story of the Sects, by Rev. William H. Lyon, in 1891. In 1890 appeared the Unitarian Catechism of Rev. Minot J. Savage, though not published by the Sunday School Society. These books attracted wide attention, were largely used in Unitarian schools, and were adopted into those of other sects to some extent. In 1886 the president of the American Social Science Association publicly urged the use of the ethical manuals of the society by all Sunday-schools. Several of these books were republished in London, and Dr. Toy's manual was translated into Dutch. The society also published a new Service Book and Hymnal, which went into immediate use in a large number of schools, and did much for the enrichment of the devotional exercises and the promotion of an advanced standard of both words and music in the hymns. [14] The Fatherhood of God, the Brotherhood of Man, the leadership of Jesus, salvation by character, the progress of mankind onward and upward forever. [15] Among the publications under Mr. Horton's administration, which may justly be called significant, are: Beacon Lights of Christian History, in three grades; Noble Lives and Noble Deeds, Dole's Catechism of Liberal Faith, Mott's History of Unitarianism, Pulsford's various manuals on the Bible, Mrs. Jaynes's Illustrated Primary Leaflets, Miss Mulliken's Kindergarten Lessons, Story of Israel and Great Thoughts of Israel, in three grades, Fenn's Acts of the Apostles, Chadwick's Questions on the Old Testament Books in their Right Order, Mrs. Kate Gannett Wells's forty Illustrated Primary Lessons, and Walkley's Helps for Teachers. Mr. Horton, during this ten years, has written fourteen manuals on various subjects. Co-extensive with the large increase of text-books has been the enrichment of lessons by pictorial aids. Excellent half-tone pictures have been prepared from the best subjects.
