Note 3 — Chapter II · CEREMONIAL CUSTOMS
Reading edition
In the case of a boy there is no physiological event so clearly marked as there is in that of a girl. It rests with the relatives and friends to decide when the boy is to become aka-op. It would seem that in the Southern tribes there is no ceremony on this occasion. Among the Northern tribes the boy is made aka-op by means of a ceremony that consists of making the scars on his back that are customary in these tribes3.
