The new life that came to the denomination in 1865 had its influence upon the Sunday School Society. In the autumn of 1866, when the Unitarian Association had secured a large increase of funds, it was proposed that the Sunday School Society should unite with it, and that the larger organization should have the direction of all denominational activities, especially those of publishing. The more zealous friends of the society did not approve of such consolidation, and succeeded in reanimating its work by appointing as its secretary Mr. James P. Walker, who had been the head of the publishing firm of Walker, Wise & Co., a young man of earnest purpose, a successful Sunday-school teacher and superintendent, and an enthusiastic believer in the mission of Unitarianism. Mr. Walker devoted his whole time to the interests of the society, and an energetic effort was made to revive and extend its work. He proved to be the man for the position, largely increasing the bookselling and publishing activities, visiting schools and conferences, and awakening much enthusiasm in regard to the interests of Sunday-schools. He wore himself out in this work, however, and died in March, 1868, greatly lamented throughout the denomination.[[11]]

After the death of Mr. Walker, consolidation with the Association was again urged; but Rev. Leonard J. Livermore was in June elected the secretary. At the annual meeting it was resolved to raise $5,000 for the work of the society, and the next year it was proposed to make the annual contribution $10,000. The name was changed to the Unitarian Sunday School Society at the annual meeting of 1868, held in Worcester. In 1871 Mr. John Kneeland became the secretary; and with the beginning of 1872 the Gazette was changed to The Dayspring, which was issued monthly. In the autumn of that year the society began the publication of monthly lessons, and there was issued with them a Teachers' Guide for the lessons of the year. With the beginning of 1877 the Guide was discontinued, and the lesson papers enlarged. In November, 1875, Rev. George F. Piper became the secretary,--a position he held until May 1, 1883. During his administration about three hundred lessons were prepared by him, and these had a circulation of about nine thousand copies. The transition condition of the denomination made it difficult to carry on the work of the society at this time, for it was impossible to please both conservatives and radicals with any lessons that might be prepared. One superintendent warned his school against the heretical tendencies of lessons which, from the other point of view, a minister condemned as being fit for orthodox schools, but not for Unitarians. In the same mail came a letter from a minister saying the lessons were too elementary, and from another saying they were much too advanced. In the latter part of Mr. Piper's term service was begun an important work of preparing manuals thoroughly modern in their spirit and methods.[[12]]

In May, 1883, Rev. Henry G. Spaulding became the secretary; and the work of publishing modern manuals was largely extended.[[13]] At the suggestion and with the co-operation of the secretary there was organized, November 12, 1883, the Unitarian Sunday School Union of Boston, having for its object "to develop the best methods of Sunday-school work." At about the same time a lending library of reference books was established in connection with the work of the society. In the autumn of 1883 the society began to hold in Channing Hall weekly lectures for teachers. In 1885 The Dayspring was enlarged and became Every Other Sunday, being much improved in its literary contents as well as in its illustrations. The same year the society was incorporated, and the number of directors was increased to include representatives from all sections of the country; while all Sunday-schools contributing to the society's treasury were given a delegate representation in its membership. Mr. Spaulding continued his connection with the society until January 1, 1892.

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.

Western Unitarian Sunday School Society.

In the west the first movement towards Sunday-school activities began in 1871 with the publication of a four-page lesson-sheet at Janesville, Wis., by Rev. Jenkin Lloyd Jones. This was continued for two or three years. Through the interest of Mr. Jones in Sunday-school work a meeting for organization was called in the fourth church, Chicago, October 14, 1873, when the Western Unitarian Sunday School Society was organized, with Rev. Milton J. Miller as president and Mr. Jones as secretary. At the meeting the next year in St. Louis a committee was appointed to prepare a song-book for the schools, which resulted in the production of The Sunny Side, edited by Rev. Charles W. Wendte. The next step was to establish headquarters in Chicago, where all kinds of material could be furnished to the schools, with the necessary advice and encouragement. Through successive years the effort of the society was to systematize the work of Unitarian Sunday-schools, to put into them the best literature, the best song and service books, the best lesson papers, and other tools,--in short, to secure better and more definite teaching, such as is in accord with the best scholarship and thought of the age.[[16]]

In 1882 the society became incorporated, and its work from this time enlarged in all directions. To develop these results more fully, an Institute was held in the Third Church, Chicago, in November, 1887, at which five sessions were given to Sunday-school work, and two to Unity Club interests. In the course of several years of encouraging success, the Institute developed into a Summer Assembly of two or more weeks' continuance at Hillside, Helena Valley, Wis., which still continues its yearly sessions. In May, 1902, The Western Sunday School Society was consolidated with the national organization; and the plates and stock which it possessed were handed over to the Unitarian Sunday School Society. A western headquarters is maintained in Chicago, where all the publications of the two societies are kept on sale.

Unity Clubs.

As adjuncts to the Sunday-school, and to continue its work for adults and in other spheres of ethical training, the Unity Club came into existence about the year 1873, beginning with the work of Rev. Jenkin Ll. Jones at Janesville. In the course of the next ten years nearly every Unitarian church in the west organized such a club, and the movement to some degree extended to other parts of the country. In 1887 there was organized in Boston the National Bureau of Unity Clubs. These clubs devoted themselves to literary, sociological, and religious courses of study; and they furnished centres for the social activities of the churches. About the year 1878 began a movement to organize societies of young people for the cultivation of the spirit of worship and religious development. This resulted in 1889 in the organization of the National Guild Alliance; and in 1890 this organization joined with the Bureau of Unity Clubs and the Unitarian Temperance Society in supporting an agency in the Unitarian Building, Boston, with the aid of the Unitarian Association. The Young People's Religious Union was organized in Boston, May 28, 1896; and in large degree, it took the place of the Bureau and the Alliance, uniting the two in a more efficient effort to interest the young people of the churches.[[17]]
