Rev. Edward A. Horton, who had for several years taken an active part in the work of the society, assumed charge February 1, 1892. Mr. Horton was made the president, it being deemed wise to have the head of the society its executive officer. During his administration there has been a steady growth in Sunday-school interest, which has demanded a rapid increase in the number and variety of publications. The book department has been taxed to the utmost to meet the demand. A new book of Song and Service, compiled by Mr. Horton, has reached a sale of nearly 25,000 copies. A simple statement of "Our Faith" has had a circulation of 40,000 copies, and in a form suitable for the walls of Sunday-school rooms it has been in considerable demand.[14] A series of lessons, covering a period of seven years, upon the three-grade, one-topic plan, has been largely used in the schools. Besides the twenty manuals published in this course of lessons, forty other text-books have been published, making a total of sixty in all, from 1892 to 1902.[15] There have also been many additions to Sunday-school helps by way of special services for festival days, free tracts, and statements of belief. The Channing Hall talks to Sunday-school teachers have been made to bear upon these courses of lessons. Every Other Sunday has been improved, and its circulation extended. The number of donating churches and schools has been steadily increased, the number in 1901 being 255, the largest by far yet reached. At the annual meeting of the society and at local conferences representative speakers have presented the newest methods of Sunday-school work. Sunday-school unions have been formed in various parts of the country, and churches are awakened to a new interest in the work of religious instruction. "Home and School Conferences" have been held with a view to bringing parents and teachers into closer sympathy and co-operation. [Sidenote: Western Unitarian Sunday School Society.]
