_Direct._ X. Especially curb or cashier the leaders of impiety and rebellion, who corrupt the rest. There are few great schools but have some that are notoriously debauched; that glory in their wickedness; that in filthy talking, and fighting, and cursing, and reviling words, are the infecters of the rest. And usually they are some of the bigger sort, that are the greatest fighters, and master the rest, and by domineering over them, and abusing them, force them both to follow them in their sin and to conceal it. The correcting of such, or expelling them if incorrigible, is of great necessity to preserve the rest; for if they are suffered the rest will be secretly infected and undone, before the master is aware. This causeth many that have a care of their children's souls, to be very fearful of sending them to great and public schools, and rather choose private schools that are freer from that danger; it being almost of as great concernment to children, what their companions be, as what their master is.
