But with the third class of doubts the case is different. These relate to the constitution of the staff of teachers, and here sufficient facts are at hand to permit a few points to be demonstrated with considerable certainty. When, for example, we ask from what source teachers are to be drawn, we are usually told that they must come from college faculties. If the method of the extension lecturer is to be as thorough as that of the universities themselves, the lecturers must be experts, not amateurs; and where except at the colleges does a body of experts exist? No doubt many well-trained men are scattered throughout the community as merchants, doctors, school-teachers, and lawyers. But these men, when of proved power, have more than they properly can attend to in their own affairs. It seems to be the colleges, therefore, to which the movement must look for its teachers; and in the experiments thus far made in this country the extension lecturing has been done for the most part by college officers. A professor of history, political economy, or literature has, in addition to his college teaching, also given a course of instruction elsewhere. This feature of the American system, one may say with confidence, must prove a constant damage to the work of the colleges and, if persisted in, must ultimately destroy the extension scheme itself. In England the extension teachers are not university teachers. To have no independent staff for extension work is a novelty of the American undertaking. The very name, university extension, besides being barbaric, is in its English employment largely misleading; since neither the agencies for extending nor indeed, for the most part, the studies extended, are found at the universities at all. A small syndicate or committee, appointed from among the university officers, is the only share the university has in the business. The impression, so general in this country, that English university teachers are roaming about the island, lecturing to mixed audiences, is an entire error. The university teachers stay at home and send other people, their own graduates chiefly, to instruct the multitude. A committee of them decides on the qualifications for the work of such persons as care to devote themselves to itinerant teaching as a profession. For those so selected they arrange times, places, and subjects; but they themselves do not move from their own lecture rooms. Nor is there occasion for their doing so. In the slender development of popular education in England, many more persons of the upper classes become trained as specialists than can find places as university teachers. There thus arises a learned and leisured accumulation which capitally serves the country in case of a new educational need. On this accumulated stock of cultured men--men who otherwise could not easily bring their culture to market--the extension movement draws. These men are its teachers, its permanent teachers,
