"That's bad," exclaimed Mr. Smith, as he hurried away, not in the best of humor, toward the hall of the scientific editors. With their heads bent down over their electric computers, thirty scientific men were absorbed in transcendental calculations. The coming of Mr. Smith was like the falling of a bomb among them. "Well, gentlemen, what is this I hear? No answer from Jupiter? Is it always to be thus? Come, Cooley, you have been at work now twenty years on this problem, and yet--" "True enough," replied the man addressed. "Our science of optics is still very defective, and through our mile-and-three-quarter telescopes--" "Listen to that, Peer," broke in Mr. Smith, turning to a second scientist. "Optical science defective! Optical science is your specialty. But," he continued, again addressing William Cooley, "failing with Jupiter, are we getting any results from the moon?" "The case is no better there." "This time you do not lay the blame on the science of optics. The moon is immeasurably less distant than Mars, yet with Mars our communication is fully established. I presume you will not say that you lack telescopes?" "Telescopes? O no, the trouble here is about--inhabitants!" "That's it," added Peer. "So, then, the moon is positively uninhabited?" asked Mr. Smith. "At least," answered Cooley, "on the face which she presents to us. As for the opposite side, who knows?" "Ah, the opposite side! You think, then," remarked Mr. Smith, musingly, "that if one could but--" "Could what?" "Why, turn the moon about-face." "Ah, there's something in that," cried the two men at once. And indeed, so confident was their air, they seemed to have no doubt as to the possibility of success in such an undertaking. "Meanwhile," asked Mr. Smith, after a moment's silence, "have you no news of interest to-day?" "Indeed we have," answered Cooley. "The elements of Olympus are definitively settled. That great planet gravitates beyond Neptune at the mean distance of 11,400,799,642 miles from the sun, and to traverse its vast orbit takes 1311 years, 294 days, 12 hours, 43 minutes, 9 seconds." "Why didn't you tell me that sooner?" cried Mr. Smith. "Now inform the reporters of this straightway. You know how eager is the curiosity of the public with regard to these astronomical questions. That news must go into to-day's issue." Then, the two men bowing to him, Mr. Smith passed into the next hall, an enormous gallery upward of 3200 feet in length, devoted to atmospheric advertising. Every one has noticed those enormous advertisements reflected from the clouds, so large that they may be seen by the populations of whole cities or even of entire countries. This, too, is one of Mr. Fritz Napoleon Smith's ideas, and in the Earth Chronicle building a thousand projectors are constantly engaged in displaying upon the clouds these mammoth advertisements.
