The first literary production of his own pen in Chinese was a tract on infant baptism; this was called forth by local conditions at Tengchow. A small sheet tract, entitled “A Prayer in Mandarin,” also followed early. As chairman of the committee appointed by the Educational Association, he made a report on chemical terms, and recommended a new and distinctively Chinese method for the symbols in that science. This was printed. In a preliminary report of the Shanghai press, made in September, 1871, he, in a list of books in course of preparation, mentions under his own name as author the following: “1. Catechism on Genesis, with answers to the more difficult questions,—_finished_, needing only a slight revision. 2. An explanation of the moral law as contained in the ten commandments,—_half-finished_. 3. Scripture Text-Book and Treasury, being Scripture references by subjects, supplying in great part the place of a concordance,—_one-third finished_.” All of these had been under way for several years, but had been frequently shunted off the track by other imperative work. Very soon after that date the catechism was published. He had a good deal to do with Julia’s “Music Book,” especially in coining appropriate terminology, though he never claimed joint authorship in it. Along with Dr. Nevius, he published a hymn book for use in Chinese services; and down to the close of his life, especially on a Sabbath when he did not preach, he now and then made an additional Chinese version of a hymn. In fact, whenever he heard a new hymn that especially moved him he wished to enrich the native collection by a translation of it into their speech. One which the Chinese came greatly to like was his rendering of the Huguenot song, “My Lord and I.” A subject that was always dominant in his mind and heart was the call to the ministry, and it was significant that one of the last things on which he worked was a translation of the hymn which has the refrain, “Here am I, send me.” It was not quite finished when his illness compelled him to lay down his pen; but recently at a meeting of the Chinese student volunteers, constituting a company rising well toward one hundred and fifty, that hymn was printed on cards, and a copy was given to each of these candidates for the ministry. In 1907 he had carried a theological class through the Westminster Shorter Catechism, and as an outcome his translation was published. This is the last religious book he made in Chinese. During his long service as a missionary he taught a number of theological classes in various studies, and his lectures were regarded as very superior, but he published none of them.
