Mallory established and maintained the first free reading room in Portland. For thirty years, it was open to all who would enter it. In it were many rare books of spiritualism and philosophy, as well as periodicals, not easily obtainable elsewhere. Mallory, with her All World Soul Communion hour, to be observed around the world, was the pioneer in the "going into the Silence" idea, collectively. Many New Thought groups have since practised this method of attaining unity of thought. In addition to her reading room and periodicals, Mallory kept parlors open for meetings held twice or three times a week. Often these were addressed by speakers of world reputation, but oftener, those with unusual ideas spoke there as the one place in the city where they could utter their thoughts in a friendly and hospitable atmosphere. Many tried their speaking powers here for the first time. Elizabeth Towne, publisher of Nautilus Magazine, Holyoke, Massachusetts, was one of these. Prince & Schaffer (2017) described Mallory as an "anarchist creative" with her cultural club, the Association of Artists and Authors. Mallory was always a vegetarian.
