*3262. Parent and child, § 3 * —when right of mother of child to its custody will ~not he curtailed. The mother of a child, its father being dead, is its natural guardian and custodian, and her right will not be infringed or curtailed unless there is something in her life and conduct which manes her an undesirable character to be intrusted with its care and nurture.
3. Infants, § 4 * —when mother is proper person to have custody of child. Where the mother of a child was shown to be a woman of education, refinement and exemplary conduct, and the only criticism upon her life or character possible to be indulged was her indiscretion in yielding under promise of marriage to the father of the child, held that she was a fit person to have its care, custody and nurture.
4. , Infants, § 4 * —when for hest interests of child that its mother have custody of it. All other things being equal, it is for the best interests of a child that it be brought up by its own mother rather than by a foster- mother.
5. Infants, § 4 * —when for hest interests of child that mother he preferred as to custody over foster mother. In a habeas corpus proceeding between the natural mother and the foster mother of a child for its custody, where the foster mother appeared to be husbandless and was employed away from her home from 5:30 to 9:30 each evening, leaving the baby in the care of others in a store, and the natural mother was shown to have a home on her father’s farm where she could give the child her maternal and undivided care and attention and rear it in the atmosphere of a healthy country environment, with the protection of her father, held that it would be to the best interests and welfare of the child that it be brought up and cared for by its natural mother.
6. Appeal and error, § 1725 * —when opinion of Appellate Court is law of case. The opinion of the Appellate Court on appeal in a former habeas corpus proceedings by a mother against the foster mother of her child is binding as the law of the case in similar proceedings between the same parties.
