American and Australian members were enthusiastic about her visits. The Detroit Lodge reported, “One of the happiest events of Miss Neff’s stay was a tea for members only, at which she held forth in her usual informal way, making us all feel like important members of the Theosophical family.” The Middle Atlantic Federation called her visit delightful: “smiling, courteous, and congenial, she seemed like an old friend… Miss Neff is a born teacher, presenting her theme in a clear and convincing manner.”
