The young minister, with so many conspicuous gifts and graces, was not allowed to remain long in the quiet pastoral charge at Dunnichen, where his ministry had been very acceptable; and in 1848--only one year after his ordination, and when not more than twenty-six years of age--he was appointed to the chair of Hebrew in St Mary's College, St Andrews, through which he had so recently passed as a student. He has himself told of the cordial welcome which he received from the venerable Principal Haldane and the other members of the professorial staff, and of the harmony with which they co-operated in the work of the College. It was not then a common thing that so young a minister should be called to occupy such a position of dignity and responsibility, nor was Hebrew then so popular a branch of study as it has, for various reasons, since become in our Divinity Halls; but the ability and success with which the Professor discharged the duties of his chair, and the salutary influence which he exerted in many ways upon the students, more than justified the appointment. He was one of the first in Scotland to introduce a scientific method in the teaching of Hebrew, and his class-room became a place of very real work, necessitating careful preparation on the part of the students. Some of these, perhaps, thought him rather exacting, and the strict discipline which he enforced was not altogether to their liking; but there were very few who did not value his good opinion, or who would not have considered it a kind of degradation to incur his displeasure; while many, imbued with something of his own spirit, attained under his guidance to such a degree of proficiency in the knowledge of the sacred tongue as made the reading of the Old Testament in the original a source of interest and pleasure to them in subsequent years. Dr William Wright, one of the greatest of Orientalists, was one of his students, and two others of them are occupants of Hebrew Chairs in Scottish Universities.
