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.
