I shall speak more particularly on this subject hereafter under the head of instruction; all I wish to secure in this place is that the teacher should make such arrangements that he can devote his exclusive attention to his classes while he is actually engaged with them.
Each recitation, too, should have its specified time, which should be adhered to with rigid accuracy.

If any thing like the plan I have suggested for allowing rests of a minute or two every half hour should be adopted, it will mark off the forenoon into parts which ought to be precisely and carefully observed.

I was formerly accustomed to think that I could not limit the time for my recitations without great inconvenience, and occasionally allowed one exercise to encroach upon the succeeding, and this upon the next, and thus sometimes the last was excluded altogether.

But such a lax and irregular method of procedure is ruinous to the discipline of a school.

On perceiving it at last, I put the bell into the hands of a pupil, commissioning her to ring regularly, having myself fixed the times, saying that I would show my pupils that I could be confined myself to system as well as they.
