The organization of Sunday schools was, at this time, being warmly taken up by the Methodists, and by many of the clergy. Raikes established the first of his Sunday schools in Gloucester in the year 1781; but a Miss Hannah Ball, of High Wycombe, a member of the Methodist society, had established one in 1769, and probably there were also others. Though Wesley had nothing to do with originating them, he early perceived in them a great promise and possibility of good, and encouraged their formation throughout his societies. His "Journal" has this reference to them: "_July 18th, 1784._ I find these schools springing up wherever I go. Perhaps God may have a deeper end therein than men are aware of. Who knows but some of these schools may become nurseries for Christians?" At Bolton, three or four years later, he met "between nine hundred and a thousand of the children belonging to our Sunday-schools. I never saw such a sight before. They were all exactly clean, as well as plain, in their apparel. All were serious and well-behaved. Many, both boys and girls, had as beautiful faces as, I believe, England or Europe can afford. When they all sang together, and none of them out of tune, the melody was beyond that of any theatre; and what is the best of all, many of them truly fear God, and some rejoice in His salvation."
In common with Wesley, Fletcher was much impressed with the Sunday-school system as it was developing throughout the country. For some years he had maintained a day school, but he now entered vigorously upon the work of organizing Sunday schools. He issued an address to his people setting forth the evils arising from the profanation of the Lord's day, and from neglecting to educate children in the principles and practice of religion. He referred to the vices by which society was degraded and injured, and asked if nothing could be done to check these growing evils. After noticing the example set in Stroud, Gloucester, Birmingham, Manchester, and many country parishes, he described a plan for establishing Sunday schools in the parish of Madeley. He proposed that the children should be taught reading, writing, and the principles of religion; that each teacher should be paid one shilling per Sunday; that inspectors should be appointed to visit the schools, to see that the children attended regularly, and the masters did their duty; that the schools be solemnly visited once or twice a year, and a premium given to the children that have made the greatest improvement. On these proposals, subsequently modified and developed, Sunday schools were established in Madeley, and another powerful agency for benefiting his parishioners was brought into existence.
