Industriana, greatest commercial and manufacturing center of Venus, had been given over momentarily to the preparations for war. The _Rhaals_ had at last turned from industry to the conquest of Tarrano. Preparations were almost completed; our armies were to start within a very few times of sleep. I had had no experience in warfare; but the history of our Earth had told me much of it. The enlisting and training of huge armies of men; arming them; artillery; naval and air forces; commissary and supplies; a gigantic business organization to equip, move and maintain millions of fighting men. Ancient warfare! This--our modern way--was indeed dissimilar. It was, from most aspects, simplicity itself. We had no need of men in great numbers. I found something like a single thousand of men being organized and trained. And equipped with weapons to outward aspects comparatively simple. On all the three worlds the age of explosives of the sort history records, was long since passed. Electronic weapons--all basically the same. And I found now that it was the power for them, developed, transformed into its various characteristics and stored for individual transportation and use, which was mainly engrossing Industriana. I had opportunity, that first night, of meeting Geno-Rhaalton--the present head of that famous Rhaalton line, for generations hereditary leaders of their race. We found him, this Geno-Rhaalton, in a secluded, somber little office of black metallic walls, grey hangings and rug, a block of carved stone his desk, and a few of the stiff-backed stone chairs, each with its single prim cushion. The office was beyond sight and sound of the busy city. His desk was empty, save for the array of apparatus around its edges--the clicking tabulators which recorded, sorted, analyzed and summarized for him every minute detail with which the city was engaged. Machines of business detail. We had them, of course, in the Inter-Allied offices of Greater New York. I have seen our Divisional Director voice into a mouthpiece the demand for some statistical summary computed up to five minutes before, and covering his entire Atlantic Division. He would have it, recorded in cold print before him, within a moment. Yet, compared to the Rhaalton efficiency, our own methods seemed antiquated indeed. This man was in touch with every transpiring detail simultaneously; yet not confused by them, for every detail was also combined into a whole--to be examined for itself if he wished. Visually as well, the entire city lay before his gaze--the walls of the office were lined with rows and tiers of small mirrors; receivers and mouthpieces connected him with everything. Sights, sounds, and even smells of the various factories were available to him--smells when his sense of smell might be necessary for the testing of some elusive gas.
