Garlock and Belle kept on studying. Neither had paid any attention at all to either Lola or James. Instead of the structural material it had once been, the bore that the thing had traversed was now full of a sparkling, bubbling, writhing, partly-fluid-partly-viscous, obscenely repulsive mass of something unknown and unknowable on Earth; a something which, Garlock now recalled, had been thought of by the Arpalone Inspector as "golop." As that unstoppable globe descended through office after office, it neither sought out people nor avoided them. Walls, doors, windows, ceilings, floors and rugs, office furniture and office personnel; all alike were absorbed into and made a part of that indescribably horrid brew. Nor did the track of that hellishly wanton globe remain a bore. Instead, it spread. That devil's brew ate into and dissolved everything it touched like a stream of boiling water being poured into a loosely-heaped pile of granulated sugar. By the time the ravening sphere had reached the second floor, the entire roof of the building was gone and the writhing, racing flood of corruption had flowed down the outer walls and across the street, engulfing and transforming sidewalks, people, pavement, poles, wires, automobiles, people-anything and everything it touched. * * * The globe went on down, through basement and sub-basement, until it reached solid, natural ground. Then, with its top a few inches below the level of natural ground, it came to a full stop and--apparently--did nothing at all. By this time, the ravening flood outside had eaten far into the lower floors of the buildings across the street, as well as along all four sides of the block, and tremendous masses of masonry and steel, their supporting structures devoured, were subsiding, crumbling, and crashing down into the noisome flood of golop--and were being transformed almost as fast as they could fall. One tremendous mass, weighing hundreds or perhaps thousands of tons, toppled almost as a whole; splashing the stuff in all directions for hundreds of yards. Wherever each splash struck, however, a new center of attack came into being, and the peculiarly disgusting, abhorrent liquidation went on. "Can you do anything with it, Clee?" Belle demanded. "Not too much--it's a mess," Garlock replied. "Besides, it wouldn't get us far, I don't think. It'll be more productive to analyze the beams the Arpalones are using to break them up, don't you think?" Then, for twenty solid minutes, the two Prime Operators worked on those enigmatic beams. "We can't assemble _that_ kind of stuff with our minds," Belle decided then. "I'll say we can't," Garlock agreed. "Ten megacycles, and cycling only twenty per second." He whistled raucously through his teeth. "My guess is it'd take four months to design and build a generator to put out that kind of stuff. It's worse than our Op field."
