Naturally enough, therefore, the organizers of the extension movement, despairing of finding among us competent unattached teachers, have turned at once to the colleges; but the colleges are a very unsafe support to lean upon. A professor in a university where the studies are elective has no more superfluous time than a busy lawyer, or doctor, or business man. Merely to keep up with the literature of a subject, to say nothing of that research and writing which should enlarge its limits, is an enormous task. Teaching too is no longer an affair of text-books and recitations. Leisurely days of routine ease belong to the past. A professor nowadays must prepare lectures incessantly; must perpetually revise them; must arrange examinations; direct the reading of his students; receive their theses; himself read a large part of their voluminous written work; personally oversee his advanced men; gather them about him in laboratory, seminary and conference; attend innumerable committee and faculty meetings; devise legislation for the further development of his college and department; correspond with schools and colleges where his students, after taking their higher degree, may suitably be placed; and if at the end of a hard-worked day he can find an hour's leisure, he must still keep his door open for students or fellow-officers to enter. So laborious have become the duties of a university teacher that few large staffs now go through a year without one or two of their members breaking down. With the growing complexity of work it often seems as if the proper business of college officers, study and teaching, must some day cease altogether, crowded out by the multifarious tasks with which they are only indirectly connected. It is useless to say that these things are not necessary. Whoever neglects them will cease to make his college, his subject and his influence grow. It is because professors now see that they cannot safely neglect them that the modern college differs fundamentally from its humdrum predecessor of a quarter of a century ago. Any movement which seeks to withdraw a professor's attention from these things, and induces him to put his soul elsewhere, inflicts on the community a serious damage. No amount of intellectual stimulus furnished to little companies here and there can atone for the loss that must fall on education when college teachers pledge themselves to do serious work in other places than in their own libraries and lecture rooms. To be an explorer and a guide in a department of human knowledge is an arduous profession. It admits no half-hearted service.
