teacher; and thus, in every appropriate, unobtrusive way, he will do whatever he can to facilitate the work of all, while hindering none. Superintendents should be very cautious whom they invite to address the school, and particularly strangers of whom they know but little, only that they are called very good men. Few persons can address a Sunday-school with profit; and certainly, without important reasons, the teachers should not be interrupted in their regular duties; for the time allotted to them is _theirs_, and even the superintendent has _no right_ to take it to oblige a friend. _Closing the School._--At the appointed moment the superintendent will call the school again to order, to sing over a verse of a hymn in harmony with the lesson; and then the superintendent may occupy not to exceed five or ten minutes in a clear, well-digested exposition of, or some pertinent remarks or questions upon, the prominent points or teachings of the lesson. Unless he can succeed in interesting and fixing the attention of both teachers and scholars with thoughts not ordinarily dwelt upon by the teachers, he had better not attempt this exercise; for few evils are greater in a school than a superintendent who talks too much. Many of our best and most successful and acceptable superintendents never attempt to address their schools, except to give their notices and necessary directions in a clear, orderly, business-like way, and then stop at once. An opportunity is then given, to distribute the library books and papers, give out the next week's lesson, sing a verse or two of the selected hymn, or with a prayer dismiss the school in regular order. _After the school_ the superintendent will receive any suggestions or requests from teachers or scholars; see that everything is left in its place; review the events of the school, and note down all his plans for improvement, and begin to study his next lesson.
