Mateer’s work in connection with the school lay only in part in the classroom; but whatever shape it took, it was always of such a character as to impress his own individuality in a remarkable degree. Both he and Julia regarded personal influence as of such vital importance that they were not quite prepared to welcome an increase of pupils so great as to hazard this element of training. Dr. Corbett says: “As a teacher he was enthusiastic and eminently successful. He was always wide-awake and never dull; so he was able to keep the attention of every student. Any attempt to deceive him was useless, and students found no comfort in going to a recitation unless they had been faithful in their preparation.” The truth is that, helpful as he gladly made himself to everybody who tried to conduct himself as he ought, he was a terror to all triflers and evildoers, old or young. Dr. Mateer’s surname in Chinese was Ti. The tiger is called Lao Hu. It is significant that among themselves his students sometimes spoke of him as Ti Lao Hu. One thing he believed with his whole heart, and endeavored to impress in every legitimate way on his pupils. This is that the highest office to which a Christian man can be called is the ministry of the gospel. In all his conduct of the school his dominating desire was to raise up faithful, able, well-educated men, filled with the Spirit, to go forth as ambassadors of Christ to win China for Him. As Dr. Corbett adds: “For this purpose he gave wise counsel, intellectual effort, unceasing toil and daily prayer. He gave of his own money freely to help the destitute, and make it possible for youths of promise to fit themselves for usefulness.”
