Hudson Tuttle (writing under control) gives the following statement of a

spirit concerning the manner in which physical phenomena are produced:

"Zoether (psychic force) emanating from the medium charges the object to

be moved, and a band of spirits directs a current of their own zoethic

emanation in the direction they desire the article to move, and it

passes along the current thus produced. The charging of the object by

the medium is necessary in order that it may be in a state of vibration

harmonious to the spirit current. If this current be directed against

the table or other charged body, raps or concussions are produced, as a

positive and negative relation exists between the spirits and the

medium's zoether. One spirit alone cannot produce physical

manifestations. If one purports to communicate, assistance will be

rendered by many others, who combine their influence."
