IF you have younger sisters, who are just entering society, all your interest should be awakened for them. You cannot but have seen some little below the surface, and already made the discovery that too few of the young men who move about in the various social circles to which you have admission, are fit associates for a pure-minded woman. Their exterior, it is true, is very fair; they sing well, they dance well, their persons are elegant, and their manners attractive; but you have met them when they felt none of the restraints of female society, and seen them unmask their real characters. You can remember the ribald jest, the obscene allusion, the sneer at virtue, the unblushing acknowledgment of licentiousness. You have heard them speak of this sweet girl, and that pure-minded woman, in terms that would have roused your deepest indignation, had your own sister been the subject of allusion. You may know all these things, but your innocent sisters at home cannot know them, nor see reason for shunning the society of those whose real characters, if revealed, would cause them to turn away in disgust and horror. From the dangers of an acquaintanceship with such young men it is your duty to guard your sisters; and you must do this more by warding off the evil than by warnings against it. In order to this, you should make it a point of duty always to go with your sisters into company, and to be their companion, if possible, on all public occasions. By so doing, you can prevent the introduction of men whose principles are bad; or, if such introductions are forced upon them in spite of you, can throw in a timely word of caution. This latter it may be too late to do after an acquaintanceship is formed with a man whose character is detestable in your eyes, provided he have a fair exterior. Your sister will hardly be made to believe that one who is so attractive in all respects, and who can converse of virtue and honour so eloquently, can possibly have an impure or vicious mind. She will think you prejudiced. The great thing is to guard, by every means in your power, these innocent ones from the polluting presence of a bad man. You cannot tell how soon he may win the affections of the most innocent, confiding, and loving of them all, and draw her off from virtue. And even if his designs be honourable--if he win her but to wed her--her lot will be by no means an enviable one; he cannot make her happy; for happy no pure-minded woman ever has been, or ever can be made, by a corrupt, evil-minded, and selfish man. You are a brother; your position is one of great responsibility; let this be ever before your mind.
