This élite of which the University is thus robbed must be got back. Since the young do not attend the lycée because they like it, they must come through necessity; to this end, other issues are rendered difficult and several are entirely barred; and better still, all those that are tolerated are made to converge to one sole central outlet, a university establishment, in such a way that the director of each private school, changed from a rival into a purveyor, serves the university instead of injuring it and gives it pupils instead of taking them away. In the first place, his high standard of instruction is limited;[6117] even in the country and in the towns that have neither lycée nor college, he must teach nothing above a fixed degree; if he is the principal of an institution, this degree must not go beyond the class of the humanities; he must leave to the faculties of the State their domain intact, differential calculus, astronomy, geology, natural history and superior literature. If he is the master of a boarding-school, this degree must not extend beyond grammar classes, nor the first elements of geometry and arithmetic; he must leave to State lycées and colleges their domain intact, the humanities properly so called, superior lectures and means of secondary instruction.--In the second place, in the towns possessing a lycée or college, he must teach at home only what the University leaves untaught;[6118] he is not deprived, indeed, of the younger boys; he may still instruct and keep them; but he must conduct all his pupils over ten years of age to the college or lycée, where they will regularly follow the classes as day-scholars. Consequently, daily and twice a day, he marches them to and fro between his house and the university establishment; before going, in the intermission, and after the class is dismissed he examines them in the lesson they have received out of his house; apart from that, he lodges and feeds them, his office being reduced to this. He is nothing beyond a watched and serviceable auxiliary, a subaltern, a University tutor and "coach," a sort of unpaid, or rather paying, schoolmaster and innkeeper in its employ.
