Of course if the work demanded elsewhere is not serious, the case is different. Rather with benefit than with damage a college teacher may on occasion recast the instruction that was intended for professionals and offer it to a popular audience. In this way a professor makes himself known and makes his college known. Many of the small colleges are now engaging in university extension as an inexpensive means of advertising themselves. But such lecturing is incidental, voluntary and perpetually liable to interruption. Beyond the immediate series of lectures it cannot be depended on. There is nothing institutional about it. The men who undertake it are owned elsewhere, and a second mortgage is not usually a very valuable piece of property. A movement which places its reliance on the casual teaching of overworked men is condemned from the start. University extension can never pass beyond the stage of amateurism and temporary expedient until, like its English namesake, it has a permanent staff of instructors exclusively devoted to its service. Where, then, is such a staff to be obtained? In view of the conditions of education in this country already described, it is improbable that it can be obtained at all. But something may still be done,--something, however, of a more modest sort than enthusiasts at present have in mind. There issue from our great universities every year a number of men who have had two or three years' training beyond their bachelor's degree. Some of them have had a year or two of foreign study. They frequently wish to teach. Places do not immediately open to them. If the extension movement would set them to work, it might have all their time at a moderate salary for two or three years. Such men, it is true, would be inexperienced, and their connection with itinerant teaching could not be rendered lasting. As soon as one of them proved his power as a teacher, some college would call him; and he would seldom prefer the nomadic and fragmentary life to an established one. Plainly too under the charge of such men the grade of instruction could not be the highest; but it might be sound, inspiriting even, and it is in any case all that present circumstances render possible. We may mourn that those who are masters in their several provinces are already fully employed. We may wish there were a multitude of masters sitting about, ready for enlistment in a missionary undertaking. But there are no such masters. The facts are evident enough; and if the extension movement aims at a durable existence, it will respect these facts. The men it wants it cannot have without damaging them; and damaging them, it damages the higher education of which they are the guardians. Teachers of a lower grade are at hand, ready to be experimented with. The few experiments already tried have been fairly successful. Let the extension leaders give up all thought of doing here what has been done in England. The principal part
