In the summer of 1768 Fletcher undertook an office which greatly increased his labours and responsibilities. The religious movement directed by the Countess of Huntingdon continuing to develop, a considerable number of chapels had, by this time, been built or hired in various parts of the country. The pulpits were generally supplied by clergymen of the Established Church, procured by the countess's personal influence. But such arrangements became increasingly difficult to make. Their 'irregularity' was disapproved in high quarters. Lady Huntingdon's chaplains were, in fact, as 'irregular' in their labours as Wesley's itinerant preachers. The system that found no place for the one could not long sanction the other; whilst her ladyship's ecclesiastical authority was a still greater anomaly than that of Wesley.

It became necessary therefore to meet the demand for earnest, evangelical preachers in some other way than by the services of the regular clergy. Meanwhile, the expulsion of six students from the University of Oxford for "being attached to the sect called Methodists, and holding their doctrines," showed that the university was hardly likely to be the nursing mother of such men as were required.

In these circumstances the countess resolved to found a school or college for the training of godly young men for the work of the ministry. She proposed to admit such as were truly converted to God and gave evidence of being called to preach the gospel, and to give them the advantage of three years' residence and instruction, at the close of which they might enter the ministry, either in the Church of England, or among Protestants of any other denomination. After taking counsel with Whitefield, Romaine, Venn, Fletcher, and others, Lady Huntingdon established the institution on which her heart was set.

Fletcher appears to have been in thorough sympathy with the countess's aims from the first. Being consulted as to the selection of books for the college, he writes: "Having studied abroad, and used rather foreign than English books with my pupils, I am not acquainted with the books Great Britain affords well enough to select the best and most concise. Besides, a plan of studies must be fixed upon first, before proper books can be chosen. Grammar, logic, rhetoric, with ecclesiastical history, and a little natural philosophy, and geography, with a great deal of practical divinity, will be enough for those who do not care to dive into languages. Mr. Townsend and Charles Wesley might, by spending an hour together, make a proper choice; and I would recommend them not to forget Watts's 'Logic,' and his 'History of the Bible by Questions and Answers,' which seem to me excellent books of the kind for clearness and order. Mr. Wesley's 'Natural Philosophy' contains as much as is wanted, or more. Mason's 'Essay on Pronunciation' will be worth their attention. Henry and Gill on the Bible, with four volumes of Baxter's 'Practical Works,' Keach's 'Metaphors,' Taylor on the Types, Gurnal's 'Christian Armour,' Edwards on Preaching, Johnson's English dictionary, and Mr. Wesley's Christian Library, may make part of the little library. The book of Baxter I mention I shall take care to send to Trevecca, as a mite towards the collection, together with Usher's 'Body of Divinity,' Scapula's Greek lexicon, and Lyttleton's Latin dictionary."

But while Lady Huntingdon received counsel and assistance from many quarters, and from Fletcher amongst the rest, there was one service for which she looked to him alone. Would Fletcher allow himself to be placed at the head of her college? Would he accept the presidency, visiting Trevecca as often as he conveniently could, to direct the studies and discipline of the place, and test the character and qualifications of the students? From his profound esteem for the countess, and in the hope of assisting in the good work of raising up an earnest ministry, Fletcher accepted the office, and, without fee or reward of any kind, threw himself heartily into its duties.

An old mansion, known as Trevecca House, in the parish of Talgarth, South Wales, was altered and adapted to the requirements of a college; tutors were procured, and the house was soon filled with students, the first of whom was a young man from Madeley, converted under Fletcher's ministry. Lady Huntingdon herself took up her residence there, and by her presence stimulated the zeal of the household. Much of the time of the students was employed in evangelistic work. On foot or on horseback they visited the towns and villages for twenty or thirty miles round, preaching in chapels and houses, in field and market-places, as opportunity allowed. The pious founder soon saw a revival and extension of the work of God which filled her heart with joy, and assured her that the undertaking, concerning which some of her best friends had their misgivings, was approved by God. At the dedication of the college and chapel, on August 24th, 1768, Lady Huntingdon's birthday, Whitefield was the preacher, and large numbers of people came together from all parts of the country. The following year, the anniversary was the occasion of a still more remarkable gathering, and of a series of religious services marked by great manifestations of spiritual power. The most eminent ministers that Lady Huntingdon's summons could assemble were present. The congregations, too large for the chapel, assembled in the court. Day by day, and almost all day long, for a week together, vast crowds were moved to tears, to rapture, and to awe under the preaching of the gospel. Howel Harris, Howel Davies, and Daniel Rowlands, men whose names are household words in Wales to-day, preached in Welsh; and Wesley, Fletcher, and Shirley in English. Thousands of voices rose in hymns of praise, and joined in fervent responses and cries of prayer. On the Saturday and Sunday, and again on the following Thursday, the Lord's supper was administered, and Fletcher addressed the communicants with an earnestness and pathos that it seemed impossible to withstand. Many were awakened and converted. "Truly God was in the midst of us," said Lady Huntingdon, "and many felt Him eminently nigh. The gracious influences of His Spirit seemed to rest on every soul.... Words fail to describe the holy triumph with which the great congregation sang—

'Captain of Thine enlisted host,
Display Thy glorious banner high.'"

After a week of never to be forgotten blessings, the great crowds slowly dispersed, and the tireless evangelists took horse and rode away, each to his work, with strength renewed, and spirit refreshed as from the presence of the Lord.

Although Fletcher did not reside at the college, his connexion with it was by no means a nominal one. His journeys to Trevecca were frequent, involving fatigue and privations, which his feeble frame could ill endure, though he counted them less than nothing. As to the character of his visits, and the influence that accompanied him, the testimony of Mr. Benson, the headmaster, himself a man of exceptional intelligence and sanctity, is well known, but is too important to be omitted here:

"Mr. Fletcher visited them frequently, and was received as an angel of God. It is not possible for me to describe the veneration in which we all held him. Like Elijah in the schools of the prophets, he was revered, he was loved, he was almost adored; and that, not only by every student, but by every member of the family. And indeed he was worthy. The reader will pardon me if he think I exceed. My heart kindles while I write. Here it was that I saw, shall I say an angel in human flesh? I should not far exceed the truth if I said so. But here I saw a descendant of fallen Adam so fully raised above the ruins of the fall, that though by the body he was tied down to earth, yet was his whole conversation in heaven, yet was his life, from day to day, hid with Christ in God. Prayer, praise, love, and zeal, all ardent, elevated above what one would think attainable in this state of frailty, were the element in which he continually lived. And as to others, his one employment was to call, entreat, and urge them to ascend with him to the glorious Source of being and blessedness. He had leisure comparatively for nothing else. Languages, arts, sciences, grammar, rhetoric, logic, even divinity itself, as it is called, were all laid aside when he appeared in the schoolroom among the students. His full heart would not suffer him to be silent. He must speak, and they were readier to hearken to this servant and minister of Jesus Christ than to attend to Sallust, Virgil, Cicero, or any Latin or Greek historian, poet, or philosopher, they had been engaged in reading. And they seldom hearkened long before they were all in tears, and every heart catched fire from the flame which burned in his soul.
