More than seven thousand years ago a heedless puff of wind had cast a sequoia seed upon the fertile earth: and now another puff had broken down its tree. For more than seventy centuries the forest giant had had its part in this life which we share, and its course (like ours, while they endure) had run curving through time and space till its circle was completed, a perfect round, as all life's movements are, and will be everywhere and evermore. Its very age was inscribed in concentric circles in the thickness of its trunk. The seasons, in their repeated going and coming, had given the impression of a slowly turning wheel, like the terrene revolution or the sun's. The sequoia, a cylinder in core, a cone in shape, had lived amongst fellow-curves. The rounded stars journey in their elliptical orbits, and the electrons likewise in their infinite degree. This unchanging changeless time rounds all things in their span. The hours encompass us, described upon their dial; and even contrasts at the last run together, made to coincide by the slow bending of every line of form. Infinity, if that be the nature of the universe, causes to meet all movement when its arc of direction is completed, and the course of time too seems circular, the rolling of a wheel. Can chaos, the abyss itself, be concentric, after the likeness of everything with which its halls are peopled? Suppose that an eagle, piercing high beyond our sight in the blue vault of heaven, had seen the giant fall. It would have thought the event and the object petty, across the vast distance. One near-by would have been moved by the greatness of the victim. The greatness and the littleness of things thus seem to depend upon the point of view--a trite, daily, observation, no doubt, but so is life itself to us. Big and little--is it not possible that proportions get their value only subjectively, and that in space they rank less important than to our minds? This concept of relativity, producing itself in everlasting stages across the horizon of our intelligence--may it not be linked with that other law of comparison, the relation of one dimension to another, which ensures something bigger than any object, however big, and something smaller than the almost infinitely small?
