Soon after the settlement of the Saints in Salt Lake valley, other valleys were explored north and south, and settlements established wherever water could be obtained, as rapidly as the strength and numbers of the Saints would justify. As early as 1860 settlements were rounded and the Saints organized in Wards and quorums of the priesthood, from Cache valley to St. George, a distance of over 400 miles from north to south. Wherever the Saints locate in settlements of a few families, or more, they are organized with a Bishop and counselors to preside over them, with Priests, Teachers and Deacons, as before explained, for a local ministry. As helps in government they had in those early days the Relief Society to relieve the poor and afflicted. The society is composed of women, and was first organized March 17, 1842, by the Prophet Joseph Smith, in Nauvoo. In 1849 the first Sunday school was established in the Church by Richard Ballantyne, in the Fourteenth Ward, Salt Lake City. Later, and during the administration of President Young, the Young Men and Young Ladies' Mutual Improvement Associations were inaugurated. Still later, by suggestion of Sister Aurelia Spencer Rogers, under the administration of President John Taylor, the Primary Associations, presided over and conducted by capable sisters, were established for the especial benefit of little children. All these are helpful regulations to meet the growing requirements of the Saints in matters of religious, moral and intellectual training and development. One of these organizations exists in every Bishop's Ward, unless the number of any class who properly belong to one of the associations named is too limited to make the organization profitable. In such cases those who would take part in such associations are not unprovided for because the Sunday school, more than any other association in the Church, takes in all ages of both sexes. Our Sunday schools now have a membership of nearly 125,000.
