"My dear Mr. Fletcher spares no pains; I know not which is greater, his earnest desire for souls, or his patience in bearing with their infirmities and dulness. His preaching is exceeding lively; and our sacraments are more like those in the chapels of London than any I have seen since I left it. Yet I find a great difference between the people here and those in Yorkshire."

Mrs. Fletcher accompanied her husband in his preaching excursions and visits to the religious societies within reach. She rode with him through the rain, and stood by his side, "where there was neither house nor church to cover them," while he preached to a large congregation who listened with "Yorkshire attention." It was not all smooth and easy work even now, among the ruder and more ignorant part of the people. On one occasion he writes: "I got many a hearty curse from the colliers for the plain words I spoke.... Had I searched the three kingdoms, I could not have found one brother willing to share gratis my weal, woe, and labours, and complaisant enough to unite his fortunes to mine; but God has found me a partner, a sister, a wife, to use St. Paul's language, who is not afraid to face with me the colliers and bargemen of my parish until death part us."

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.

The labours of many years had, indeed, begun to tell, not only on individuals, but on the general tone and character of the community. Vice was checked and restrained; the people were better disposed towards religion; the standard of morals was raised; the conversion of notorious evil doers made its impression upon the conscience of the careless and profane; something like a general reformation had taken place in the parish, and the progress of religion and morality was now further aided by the regular religious instruction of the young. Love for children was characteristic of Fletcher all through life. He was never happier than when amongst them. Before his Sunday-school was opened, he used to meet some two or three hundred of them on a Thursday evening, and he continued to do so to the very week in which his last illness began. As a result of this, a loving remembrance of him remained in the neighbourhood where he had lived much longer than is usually the case, even with the best of men. The image of his person and character, stamped upon the hearts of children, was found sixty, seventy years afterwards, in the hearts of aged men and women.

Among the young people over whom Fletcher exercised a powerful and lasting influence was Melville Horne, who was introduced to him when seventeen years of age. At their first interview a deep impression was made upon the youth's mind, and he afterwards sought every opportunity of being in Fletcher's company. At the vicarage he came to be treated almost as a son. He subsequently received ordination, and, upon Fletcher's death, became curate of Madeley. When far advanced in life he would refer with deep feeling to his early intercourse with Fletcher. He says: "I know not which most to venerate, his public or private character. Grave and dignified in his deportment and manners, he yet excelled in all the courtesies and attentions of the accomplished gentleman. In every company he appeared as the least, the last, and the servant of all. From head to foot he was clothed with humility; while the heavenly-mindedness of an angel shone from his countenance, and sparkled in his eyes. His religion was without labour and without effort, for Christianity was, not only his great business, but his very element and nature. As a mortal man, he doubtless had his errors and failings; but what they were, they who knew him best would find it difficult to say, for he appeared as an instrument of heavenly minstrelsy, attuned to the Master's touch.... In every view, he was a great man, and entitled to rank in the very first class of ministers; but it was his goodness that raised him above all the ministers of his day."

In August, 1783, Fletcher and his wife visited Ireland. They had received a pressing invitation from the Methodists of Dublin to come over and spend a few weeks there, and help them in the good work. As long as it seemed possible to decline the invitation they had done so; but the requests were so urgent that it seemed to them at last that this was a call from God. Fletcher's health at the time was not good, and on various grounds they both shrank from so long and formidable a journey; but the conviction that it was God's will settled the matter. On the day they set out they rode to Shrewsbury, paying a tribute of love and reverence to the memory of Richard Baxter as they passed through the village of Eaton Constantine, his early home. The next day they reached Llangollen, where, for want of a change of horses, they were detained for the night. A few persons who could understand English came together next morning, and Fletcher preached to them before resuming his journey.

They remained about six weeks in Dublin, and their labours were made a great blessing to many. Fletcher preached with his accustomed unction and power. His host, a gentleman of position and influence in the city, applied to the rector of the parish in which he lived to allow Mr. Fletcher to preach in his church, and this was immediately granted. The church was crowded to excess. The congregation was greatly moved; but when it became known that he had preached on the evening of the same day at the Methodist chapel, all the churches were at once closed against him, with the exception of the Huguenot French church. Here he preached, both in French and in English. Even when he preached in French, people who could not understand a word would be present. "We go to look at him," they said, "for heaven seems to beam from his countenance." In addition to his public labours Fletcher met the members of the society in private, and exhorted and counselled them to their great comfort. Mrs. Fletcher met the classes of women. A great revival of religion followed. The Methodist society increased in numbers from about five hundred persons to upwards of a thousand, and the spiritual life of many was deepened and enriched.

When Fletcher was about to leave them the grateful people pressed him to accept a sum of money in payment of his expenses. This he entirely refused to accept, until being pressed in such a manner that further refusal seemed impossible, he consented to receive it on condition that he might dispose of it as he pleased. To this they readily agreed, and every penny of it was given to their own poor people before Fletcher and his wife left Dublin. A letter warmly thanking them for "your labour of love in crossing the sea to visit us, and your spending body and soul for our profit while among us," was signed by one hundred and fifty-one members of the Dublin Methodist society, and sent after them to Madeley. The passage from Dublin to Holyhead was a stormy one, but they reached their home at last in peace.
