Note 121 — Chapter XIV · WHAT YOU MUST BELIEVE TO BE A SPIRITUALIST
Reading edition
I gave a pseudo seance for Sophie Irene Loeb and had two slates which were examined by the Circle and marked. I asked if the Spirits would manifest and when the slates were opened there was a message containing a code word. Miss Loeb was astounded, for the message signed by Jack London contained a word which she claimed no one in the whole world knew about. I did it by trickery but she declared that if she had not known I was a magician she would have believed readily that I had psychic powers.
