If the circle be one devoted chiefly to the development of mediumistic powers in some one of its members, then it will perhaps be best to have only that particular medium present. The remainder of the sitters should be highly sympathetic toward the developing medium, and should assume the mental attitude of help and aid toward him. While the early results of such a circle may not be so interesting as those at which a fully developed medium is present, nevertheless the gradual unfoldment of the powers of the medium will be found highly interesting, and the gradual evolution of the character of the phenomena produced will be a liberal education in itself. In case that in the circle there are no particular persons regarded as being mediums, and where there is a general desire to develop mediumistic powers among many or all of the sitters, there must be carefully avoided anything approaching a rivalry between the members of the circle; and at the same time a strong desire and perfect willingness for the spirit power to manifest through whomsoever it may prefer, without regard to the personal ambitions of the individual sitters. Most certainly there must be no spirit of "competition" among the sitters in the circle. The Personnel of the Circle. The personal composition of the spiritualistic circle is a very important matter, and those entering into circle work should pay careful attention to the personal and psychical character of those composing the circle; and it may be added here that such work requires very nice powers of discrimination, and a great degree of tact, in order to preserve the proper character of the circle, and at the same time to avoid wounding the pride of those who are to be rejected. Regarding the character of those composing the circle, the following statement of a practical medium will be found of importance. "There are some people who are so sensitive that they should not sit in circles, because they are liable to become charged with the psychic emanations from, and dominated by the expectancy of, the sitters, but who are not influenced by spirit power to any great extent. Or probably there may exist 'cross magnetism,' that is to say the inharmonious magnetism of different members who are antagonistic to each other. Some sitters may be sarcastic, merely curious, or selfish, or mercenary, or not over clean, sober or scrupulous, and all such surroundings act and react upon the highly sensitive organization of the undeveloped medium, and, above all, provide conditions favorable for the manifestations of mischievous or malicious spirits, unless the medium is sufficiently developed, or is protected by wise spirits powerful enough to resist or control such influences. Like attracts like, as a general rule; but there are exceptions to this, as to most rules, as, for instance, where unfortunate or unhappy spirits are permitted to manifest, and are even brought to the seance by other and more experienced spirit people, so
