The Boylston Professorship of Rhetoric and Oratory, to which, as has been already mentioned, Mr Child succeeded on his return to America toward the end of 1851, was no sinecure. In addition to academic instruction of the ordinary kind, the duties of the chair included the superintendence and criticism of a great quantity of written work, in the nature of essays and set compositions prepared by students of all degrees of ability. For twenty-five years Mr Child performed these duties with characteristic punctuality and devotion, though with increasing distaste for the drudgery which they involved. Meantime a great change had come over Harvard: it had developed from a provincial college into a national seminary of learning, and the introduction of the "elective system"--corresponding to the "Lernfreiheit" of Germany--had enabled it to become a university in the proper sense of the word. One result of the important reform just referred to was the establishment of a Professorship of English, entirely distinct from the old chair of Rhetoric. This took place on May 8, 1876, and on the 20th of the next month Mr Child was transferred to the new professorship. His duties as an instructor were now thoroughly congenial, and he continued to perform them with unabated vigor to the end. In the onerous details of administrative and advisory work, inseparable, according to our exacting American system, from the position of a university professor, he was equally faithful and untiring. For thirty years he acted as secretary of the Library Council, and in all that time he was absent from but three meetings. As chairman of the Department of English and of the Division of Modern Languages, and as a member of many important committees, he was ever prodigal of time and effort. How steadily he attended to the regular duties of the class-room, his pupils, for fifty years, are the best witnesses. They, too, will best understand the satisfaction he felt that, in the fiftieth year of his teaching, he was not absent from a single lecture. No man was ever less a formalist; yet the most formal of natures could not, in the strictest observance of punctilio, have surpassed the regularity with which he discharged, as it were spontaneously, the multifarious duties of his position.
