According to Professor Ó hÓgáin, "The Cailleach Bhéarra was credited with extremely sharp sight, being able to discern from a distance of twenty miles. It is said that she never carried mud on her feet from one place to another, and never threw out dirty water before bringing in clean." (Ó hÓgáin, Dáithí.
