"The Library of Durab was on this spot. It boasted fourteen million volumes. None exist today. Long after the builders had gone, I spent time reading the books of the Library and they are memorized within me--" "The Plague struck down nine thousand a day for more than a year, in that time--" It went on and on, a cyclopean newsreel, growing in detail as Ozymandias absorbed our comments and added new words to his vocabulary. We followed the robot as it wheeled its way through the desert, our recorders gobbling in each word, our minds numbed and dazed by the magnitude of our find. In this single robot lay waiting to be tapped the totality of a culture that had lasted three hundred thousand years! We could mine Ozymandias the rest of our lives, and still not exhaust the fund of data implanted in his all-encompassing mind. When, finally, we ripped ourselves away and, leaving Ozymandias in the desert, returned to the base, we were full to bursting. Never in the history of our science had such a find been vouchsafed: a complete record, accessible and translated for us. We agreed to conceal our find from Mattern once again. But, like small boys newly given a toy of great value, we found it hard to hide our feelings. Although we said nothing explicit, our overexcited manner certainly must have hinted to Mattern that we had not had as fruitless a day as we had claimed. That, and Leopold's refusal to tell him exactly where we had been working during the day, must have aroused Mattern's suspicions. In any event, during the night as we lay in bed I heard the sound of halftracks rumbling off into the desert; and the following morning, when we entered the mess-hall for breakfast, Mattern and his men, unshaven and untidy, turned to look at us with peculiar vindictive gleams in their eyes. * * * * * Mattern said, "Good morning, gentlemen. We've been waiting for some time for you to arise." "It's no later than usual, is it?" Leopold asked. "Not at all. But my men and I have been up all night. We--ah--did a bit of archaeological prospecting while you slept." The Colonel leaned forward, fingering his rumpled lapels, and said, "Dr. Leopold, for what reason did you choose to conceal from me the fact that you had discovered an object of extreme strategic importance?" "What do you mean?" Leopold demanded--with a quiver taking the authority out of his voice. "I mean," said Mattern quietly, "the robot you named Ozymandias. Just why did you decide not to tell me about it?" "I had every intention of doing so before our departure," Leopold said. Mattern shrugged. "Be that as it may. You concealed the existence of your find. But your manner last night led us to investigate the area--and since the detectors showed a metal object some twenty miles to the west, we headed that way. Ozymandias was quite surprised to learn that there were other Earthmen here."
