As to the organization of the schools: if possible the children should all wear the same kind of clothing, even if the fabric is varied. It is preferable that the fabric as well should be uniform; if, however, this is not possible, there is no harm done. The more cleanly the pupils are, the better; they should be immaculate. The school must be located in a place where the air is delicate and pure. The children must be carefully trained to be most courteous and well-behaved. They must be constantly encouraged and made eager to gain all the summits of human accomplishment, so that from their earliest years they will be taught to have high aims, to conduct themselves well, to be chaste, pure, and undefiled, and will learn to be of powerful resolve and firm of purpose in all things. Let them not jest and trifle, but earnestly advance unto their goals, so that in every situation they will be found resolute and firm.
