"In the spring of the year 1828, a higher influence was brought to bear, reinforcing and extending the moral element throughout the college; recovering not a few from irregularities of conduct and waste of talent; awakening the religious nature; giving birth to new motives, and leading many to noble and useful lives. From that period until our class graduated in 1828, I cannot recall an act deserving special even animadversion, nor remember an instance of a student obnoxious to discipline for indolent of other censurable habits. But I remember several young men of exemplary deportment and distinguished ability, among them Salmon P. Chase, who though not publicly regarded as 'subjects of the work,' were greatly affected, their future being largely determined by it. They all subsequently exhibited deep moral and religious purpose, and were foremost in philanthropic action. Without the preaching of Dr. Tyler as its great instrument, and without such a man presiding over it, and guiding it, there is no reason to suppose that the revival would have taken place, or would have been so extensive and powerful. "It is by looking at Dr. Tyler from every point of view that we alone can form a just estimate of his qualities. His greatest power was that of preacher, and he was most at home in this office. He did not seek it, but it providentially came to him in the illness of Professor Shurtleff, the professor of Theology, and he retired from it when in the year 1827, Professor George Howe succeeded Professor Shurtleff. He had risen in it to the very height of the duty he attempted to discharge, and was majestic in it. His mode of delivery and gesture were beyond criticism, and at times sublime. I never heard a student speak of him in this capacity without the highest praise; and his power ended not simply in producing admiration, but in influencing his hearers to duty. The great object aimed at in his preaching was to induce his hearers to be willing, unconditionally, to do and submit to the revealed Divine will. He who succeeds in persuading his fellow-men to faithfully and perseveringly try to do this, does the highest Christian work, and most for the benefit of man. No one who has sat in the presidential chair of Dartmouth, or of any other college, during an equal length of time, has done more in this direction than Bennet Tyler." The librarian says:
