The crystal rock under microscopic examination shows the same beautiful figures and marvelous lines of arrangement that in winter the new fallen snow-flakes exhibit, and indicate that the lines of form are essentially the same that gave the planetary rock its forms of crystalline beauty and massive structure. And the beautiful snow that falls so gently upon the wintry lap of earth is one of the best representatives of creative power acting in the primitive states of formative forces. This tends to show that the earth began its formative period in extreme cold and not heat, for the formative lines of shape and force are the same in the crystal ice and crystalline snowflake as they are in the crystalline rocks of earth's primary foundations. And they all indicate the lines of electric energy and magnetic force in atomic activity and molecular formations, which are the beginning of all visible material creations. The shaping of the molecules of the so-called cosmic elements by electric energy into crystalline form is the second great step in world building. While magnetism (the dual force of electricity) serves to hold the form-structure in more or less enduring relations, for the magnet has the power to radiate atomic force in circles and tends to draw the elements into form and hold them there. The electric force keeps the atoms always moving; the magnetic force keeps them or would keep them in atomic balance, or at rest, but electricity keeps magnetism always on the alert, and between the action of the two, or attraction and repulsion, all visible forms are evolved and dissolved. Thus magnetism is the centripetal force, of planetary construction, and electricity the centrifugal power of planetary changes, and upon these two depend all the complex varieties of inorganic and organic forms that exist. And so long as they exist with their powers of atomic motion so long will world building and form building continue, and must continue through the æons of creative force. The magnetic state of the earth, with the pulsating currents of electric force in the atomic and radiant form, plays a sovereign part in the economy of nature and makes the planet itself alive with creative force and evolving power.
