At the present time Keely is concentrating his efforts on the perfecting of his mechanical conditions to that point where, according to his theories, he will be able to establish, on the ninths, a sympathetic affinity with pure, polar, negative attraction, minus magnetism. In his own opinion he has so nearly gained the summit, or completion of his "graduation," as to feel that he holds the key to the control of the infinitely tenuous conditions which lie before him to be conquered, before he gains mastery of the group of depolar disks that he is now working upon. Twenty-six groups are completed, and when the twenty-seventh and last group is under equal control, Keely expects to establish a circuit of vibratory force, for running machinery: both for aerial navigation and for terrestrial use. If this result be obtained, Keely will then be in a position to give his system to science; and to demonstrate the ever-operative immanence of the Infinite builder of all things of whom our Lord said, "My Father worketh hitherto, and I work." In commercial use Keely expects that when the motion has been once set up, in any of his machines, it will continue until the material is worn out. It is this claim which has caused Keely to be classed with perpetual-motion seekers. For years Keely has been trying to utilize his discoveries for the material and moral advantage of humanity: and yet he feels, as Buckle has said of the present acquirements of science, that the ground only is broken, that the crust only is touched. The loftiest pinnacle which has been reached by the men who are foremost in their constructions of the method by which the one source of all energy works in the material world, is too insignificant a position to obtain even an outlook towards the vast realm that Keely figuratively describes as the infinite brain; or the source from which all "sympathetic-leads" emanate, that connect mind with matter. Realizing that all conditions of matter are but as vain illusions, he never falters in his determination to reach after the hidden things of God, if haply he may find them. Even the goal which he seeks to attain lies, in his own estimation, on the outermost border of this crust; and well he knows that it never can be reached in any other way than by principles of exact science and by pursuing a path that is at all times lighted by reason. Believing that "the horizon of the world of matter, which has been thought to rest over hydrogen, extends to infinite reaches, including substances which have never been revealed to the senses," he knows how unfathomable is the ocean that lies beyond, and like Newton compares himself to one who is gathering pebbles on its shore. Science, which has ever been interested both in the infinitely small and infinitely great, has in our age dropped the only clue that can guide through the obscure labyrinth which leads into depths of nature lying beyond the knowledge of our unaided senses.
