It is reasonable to presume that one's daily life can supply the true answer. To what use are we employing the faculties we already have, all of them acquired with as much pain and suffering, it may be, as any new ones we are ever likely to evolve? If we are using these faculties for the benefit of the race we shall employ others that are higher to even greater effect. In other case it is not worth the effort of acquiring, nor is it likely that anybody of a radically selfish nature will take the trouble to acquire it. Natural selection is the fine sieve which the gods use in their prospecting. The gross material does not go through. CONCLUSION. The foregoing short treatise will gain some practical value by a statement of the conditions most suitable for scrying. A diffused natural light, preferably from the north, is always better than an artificial light. The subject should sit with his back to the source of light, at a distance from the mirror determined by its focus; or if the agent be a crystal it should be held in the hands, one supporting the other. Steady gazing in complete silence should be maintained for a quarter of an hour, which may be afterwards gradually extended to half or even a full hour. Success depends largely upon idiosyncrasy and temperamental aptitude. Seers are often to be found among men and women of imperfect education owing to fitness of temperament; seers of this order are born with the faculty. Others, seemingly non-sensitive at first, may develop the faculty after a few short sittings. The eyes should not be strained, but the gaze should be allowed to rest casually yet steadily on the agent as if one were reading a book. It will be found that the sight is presently drawn inwards to a focus beyond the surface of the agent. This opening up of the field of vision is the symptom of success. The next step is indicated by a change in the atmosphere of the field. Instead of reflecting or remaining translucent, the agent will appear to cloud over. This will appear to become milky, then to be diffused with colour which changes to black or murky brown, and finally the screen appears to be drawn away, revealing a picture, a scene, figures in action, symbolical forms, sentences, etc. The physiological symptoms are: first, a slight chill along the spine like cold water trickling from the neck downwards; secondly, a returning flush of heat from the base of the spine upwards to the crown of the head; thirdly, a gaping or spasmodic action of the brain; and lastly, a deep inward drawing of the breath, as if sobbing. When these symptoms follow closely upon one another, vision will be assured. It generally happens, however, that the various symptoms are separately developed by repeated sittings, only appearing in proper sequence when the experiment is finally successful.
