That cabinet became instantly a manifold scanner, all its reels flashing through as one. Simultaneously there appeared in the air above the machine a three-dimensional model of all the Galaxies there listed. A model upon such a scale that the First Galaxy was but a tiny lenticular pellet, although it was still disproportionately large; upon such a scale that the whole vast sphere of space covered by the hundreds of Fenachrone scrolls was compressed into a volume but little larger than a basketball. And yet each tiny Galactic pellet bore its own peculiarly individual identifying marks. Then Dorothy felt as though she herself had been hurled out into the unthinkable reaches of space. In a fleeting instant of time she passed through thousands of star clusters, and not only knew the declination, right ascension, and distance of each Galaxy, but saw it duplicated in miniature in its exact place in an immense, three-dimensional model in the hollow interior of the space-flyer in which she actually was. The mapping went on. To human brains and hands the task would have been one of countless years. Now, however, it was to prove only a matter of hours, for this was no human brain. Not only was it reactive and effective at distances to be expressed in light-years or parsecs: because of the immeasurable sixth-order velocity of its carrier wave it was equally effective at distances of thousands upon thousands of light--millionia--reaches of space so incomprehensibly vast that the rays of visible light emitted at the birth of a sun so far away would reach the point of observation only after that sun had lived through its entire cycle of life and had disappeared. "Well, that's about enough of that for you, for a while," Seaton remarked in a matter-of-fact voice. "A little of that stuff goes a long ways at first--you have to get used to it." "I'll say you do! Why--I--it--" Dorothy paused, even her ready tongue at a loss for words. "You can't describe it in words--don't try," Seaton advised. "Let's go outdoors and watch the model grow." To the awe, if not to the amazement of the observers, the model had already begun to assume a lenticular pattern. Galaxies, then, really _were_ arranged in general as were the stars composing them; there really _were_ universes, and they really _were_ lenticular--the vague speculations of the hardiest and most exploratory cosmic thinkers were being confirmed. For hour after hour the model continued to grow and Seaton's face began to take on a look of grave concern. At last, however, when the chart was three fourths done or more, a deep-toned bell clanged out the signal for which he had been waiting--the news that there was now being plotted a configuration of Galaxies identical with that portrayed by the space chart of the Fenachrone.
