t be always remembered that the medium is not the active agent in
the production of mediumistic phenomena--he is not called to DO anything
except to passively act as the medium or channel of communication
between the two planes of existence. He is always the intermediary
between the two planes, and is not the active agent on either plane. The
active agents are the spirits on the one plane, and the sitters in the
circle on the other plane. The sitters must supply much of the actual
operative power from the one plane, and the spirits must do all of the
communication from the other plane. The medium serves to connect the two
opposite ends of the psychic telephone system so that the messages may
pass through and over the mediumistic channel, secure and maintain the
best psychic conditions.

The Role of the Spirits.

We have spoken of the part of the work which it is necessary for the
sitters to perform in order to And now we shall have something to say
concerning the part to be played properly by the spirits wishing to
communicate. It must not be supposed for a moment that every spirit is
possessed of the necessary knowledge enabling it to communicate easily
through a medium, or even to develop the medium so that he may become an
efficient channel of communication. Spirits are frequently found to be
sadly deficient in such knowledge and experience, and the development of
the medium as well as the production of satisfactory phenomena, suffer
from this lack. The spirits who seek to use a medium may or may not be
fitted for such task. Many spirits are utterly unable to properly
develop a medium; some fail by reason of their lack of knowledge, and
others fail because of their lack of special aptitude for the task.

Differences Among Spirits.

A writer on this subject well says regarding this particular point:
"Some spirits may lack both knowledge and aptitude; others may have the
knowledge, but yet fail from want of the power to control. They may be
able to affect one mediumistic person and not another. Likewise, they
may be able to use a sensitive medium for one phase of mediumship, and
yet be unable to succeed in any other direction. A spirit may be in such
conditions that he can produce good physical phenomena; he may, however,
try to do so through a sensitive who is fitted only for trance or
clairvoyant mediumship, but who does not possess the quality or psychic
force for sensuous manifestations. A medium who is natu
