into imprudent extremes of exertion. He would commit to memory fifteen chapters of the Bible as an evening exercise after the labours of the day, and after such killing efforts, allow himself but four hours of repose. To this excess of exertion he was probably stimulated by the near approach of the period to which he had long looked forward with trembling hope the day which was to reward the toils and trials of his various youth, by investing him with the solemn function of an ambassador of Christ. During the vacations of his school, he was now engaged in the regular study of philosophy and divinity under the inspection of the Associate Synod, and the superintendence of the Rev. Ebenezer Erskine, and James Fisher, two of the original founders, and principal lights of the Secession church. At length, in the year 1751, having completed his preparatory course of study, and approved himself on trial before the Associate Presbytery of Edinburgh, he was licensed by that reverend body, at Dalkeith, to preach the gospel in their society. He entered upon the sacred work with deep impressions of its solemn responsibilities. He has himself mentioned that his mind, immediately previous to his receiving authority to preach, was very vividly affected by that awful text in Isaiah vi. 9, 10, "He said, Go and tell this people, Hear ye indeed, but understand not; see ye indeed, but perceive not; make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and convert and be healed." He had not been long a probationer, when he received two nearly simultaneous calls to the settled discharge of ministerial duty; one from the congregation of Stow, a village in the shire of Edinburgh, and the other from that of Haddington, the principal town in the county of that name. The Presbytery of Edinburgh, within whose bounds both congregations were included, and which had therefore, according to the Presbyterian constitution, the right of deciding between their competing claims, submitted the matter to his own discretion. His choice was determined to Haddington, partly by his feelings of sympathy with that congregation for disappointments it had already experienced, and partly by his modest estimate of his own qualifications, to which he felt the smaller of the two charges more suitable. Over this congregation therefore he was finally ordained pastor in the month of June, 1751. It deserves to be mentioned, however, that he continued regularly to visit and examine the congregation of Stow until it was supplied with a regular minister.
To the duties of the sacred office he devoted himself with the most zealous and laborious industry. The smallness of his congregation enabled him at once to undertake the widest range of ministerial duty, and to execute it with the greatest minuteness and accuracy. Besides regularly preaching four discourses every Sunday during the summer, and three during winter in his own place of worship, and occasionally in the country during the week, he visited all his people annually in his pastoral capacity, and carried them twice in the same period through a course of public catechetical examinations. He was very assiduous in his visits to the sick and the afflicted, and that not merely to those of his own congregation, but to all, of every denomination, who desired his services. The peculiar characteristic of his manner of address on all these occasions, public and private, was an intense solemnity and earnestness, which extorted attention even from the scorner, and was obviously the genuine expression of his own overwhelming sense of the reality and importance of the message. "His grave appearance," says a late English divine, who had attended his ministry for some time, "his solemn, weighty, and energetic manner of speaking, used to affect me very much. Certainly his preaching was close, and his address to the conscience pungent. Like his Lord and Blaster, he spoke with authority and hallowed pathos, having tasted the sweetness and felt the power of what he delivered." To the same
