While the liberal policy which laid the foundation for this expansion of the University's field may properly be said to have been formed during President Tappan's administration, it was continued and wisely expanded under his successors. President Haven's first years were difficult, but he had the support of his colleagues and was fortunate in the appointment of the new members of the Faculty necessitated by the reorganization which ushered in his administration. One of the first of his appointments was that of Dr. Bruennow's favorite pupil, James C. Watson, '57, to succeed him as Professor of Astronomy and Director of the Observatory. Professor Watson's brilliant work had already attracted wide attention, he "was bagging asteroids as though he lured them with a decoy" though he was at that time still a very young man, and his methods as a teacher somewhat peculiar. He paid scant attention to those not vitally interested in his subject, and, as one chronicler observed, showed the folly of a set course of studies and contributed in this way not a little to the eventual adoption of the elective system in the University. His lectures were sometimes brilliant and always lucid, though he was not exacting in recitations or in examinations. The story is told of his passing one student in an examination who had died earlier in the year; he had merely taken the name from the roll prepared the first day of the semester. Whatever were Professor Watson's personal qualifications, however, the long list of eminent astronomers who were his pupils during the years from 1863 to 1879 are ample evidence of his genius, for they include such names as those of his successor Professor Harrington, '68, Otto J. Klotz, '72_e_, of the Observatory of the Dominion of Canada, Monroe B. Snyder, '72, Director of the Philadelphia Observatory, Robert Simpson Woodward, '72_e_, President of the Carnegie Institution, John M. Schaeberle, '76_e_, Astronomer in the Lick Observatory from 1888 to 1897, and George Cary Comstock, '77, Director of the Observatory of the University of Wisconsin. Edward Olney, whose spirit still lives in the memory of older graduates, also came at this time. He was, unlike most other members of the Faculty, for the most part a self-made scholar of whose ability as a teacher one former student rather ruefully remarked that the "students knew something about mathematics when they got through with him." He was always a prominent figure in the shaping of University policies and to him no small measure of credit is given for the diploma system of admission from the high schools in '71 and the elective system of '78.
