Anyone acting as a guardian of a boy or girl, and any Guardian of the who supervises that guardian by virtue of being appointed to control him, must show this child who has had the misfortune of bereavement no less affection than his own children, and be just as zealously concerned for his ward's property as he is for his own more so, in fact; and everyone who acts as a guardian will have just that one law to observe on the subject of orphans.
