joined one of the great monastic orders, vowing to devote all the remainder of his life to prayer, first for the soul of his son, and secondly that henceforward no descendant of his might ever again encounter what seemed to his simple and pious mind the terrible danger of meeting death unprepared. Day after day for many a year he poured all the energy of his soul into the channel of that one intense wish, firmly believing that somehow or other the result he so earnestly desired would be brought about. A student of occultism will have little difficulty in deciding what would be the effect of such a definite and long-continued stream of thought; our knightly monk created an artificial elemental of immense power and resourcefulness for its own particular object, and accumulated within it a store of force which would enable it to carry out his wishes for an indefinite period. An elemental is a perfect storage-battery--one from which there is practically no leakage; and when we remember what its original strength must have been, and how comparatively rarely it would be called upon to put it forth, we shall scarcely wonder that even now it exhibits unimpaired vitality, and still warns the direct descendants of the old crusader of their approaching doom by repeating in their ears the strange wailing music which was the dirge of a young and valiant soldier seven hundred years ago in Palestine. 2. _Elementals formed consciously._ Since such results as have been described above have been achieved by the thought-force of men who were entirely in the dark as to what they were doing, it will readily be imagined that a magician who understands the subject, and can see exactly what effect he is producing, may wield immense power along these lines. As a matter of fact occultists of both the white and dark schools frequently use artificial elementals in their work, and few tasks are beyond the powers of such creatures when scientifically prepared and directed with knowledge and skill; for one who knows how to do so can maintain a connection with his elemental and guide it, no matter at what distance it may be working, so that it will practically act as though endowed with the full intelligence of its master. Very definite and very efficient guardian angels have sometimes been supplied in this way, though it is probably very rarely that Karma permits such a decided interference in a person's life as that would be. In such a case, however, as that of a pupil of the Adepts, who might have in the course of his work for them to run the risk of attack from forces with which his unaided strength would be entirely insufficient to cope, guardians of this description have been given, and have fully proved their sleepless vigilance and their tremendous power. By some of the more advanced processes of black magic, also, artificial elementals of great power may be called into existence, and much evil has been worked in various ways by such entities.
