each other." As a
writer has said: "Remember also that you are merely experimenting, and
that the spirit people are also, perhaps for the first time, trying to
penetrate the veil and utilize powers and agencies of which, in all
probability, they know as little as do you. So many disturbing factors
exist--weather, varying psychical conditions of the sitters, agitated
mental states, too great expectancy, or anxiety for successful
demonstrations--that the true disposition to be maintained by the
inquirer is that of the scientific student, who carefully watches what
transpires, and endeavors to discover the causes of failure as well as
the conditions which favor success."

Flashes of Communication.

In some cases the circle will have to sit several times before the
persistent though disconnected and apparently meaningless raps or
table-tilts will begin to show positive signs of intelligent signalling.
The same thing would probably occur were the inhabitants of the planet
Mars to find themselves able to flash signals to our earth--for a long
time the flashes would seem meaningless to us, until at last they would
seem to manifest a definite intelligent purpose and rhythm. When this
stage of the raps or table-tilts has been reached, then the leader of
the circle should acquaint the spirits with the code used, and ask
definite questions concerning the future conduct of the seance, the
answers to which the spirits are requested to give through the signal
code of raps or tilts. When these answers begin to "come through"
plainly and definitely, then the seance enters a new phase.

Spirit Code Signals.

In this new phase, when once entered into, the formal set procedure to
be followed will be about as follows: The leader of the circle,
recognizing the signs of the presence of spirits in the circle, will
address them and ask them whether or not there is a spirit present who
wishes to convey a message to the circle, or to any one present. Then
the spirits signal back in the affirmative or the negative. If the
answer be in the affirmative, the circle leader asks the spirits to
indicate by the affirmative signal when the name of the right person
present is named--and he then proceeds to slowly and plainly name each
person present, in succession, until the affirmative signal is received.
Or, he may ask the spirits to indicate the identity of the spirit
friends present, when their names are called; and he then proceeds to
call
