"Its movements were lifelike," I replied. "They suggest muscular action rather than mechanical drive. But, as Walt says, it's just not possible. Nature has placed a limit on the size of living creatures. The strength of bones, the energy requirements, the osmotic pressures needed to move fluids through tissue. Besides, where could it come from? There have been giants--eight, ten, maybe up to twelve feet--but this thing is of a different order of magnitude. It must weigh millions of pounds. As a zoologist, I can't believe that it's alive." Martin and Chamberlin had a few more remarks of the same nature, and then the conversation died away. We waited. Eventually they would come--the yellow-robed ones. When they did, we might learn more. I had little doubt as to our ultimate fate, but in the dulled condition of my senses, I didn't seem particularly to care. My watch had been smashed in the struggle, so that I had no idea of how long they kept us in the cell. It could not have been too many hours, for the elementary needs of nature had only begun to assert themselves when the sound of a key came from the door. We all stood up. It was our conductor of last night, the one who spoke pidgin English. "Good morning, gentlemens," he said with a bow. "You spend nice night, yes? Get plenty sleep?" We did not reply. Still smiling politely, he beckoned. "Now please to come with me. Head Lama talk to you now." * * * * * Once more we traversed the interminable concrete corridors of that subterranean city, but this time we came out into a hall illuminated by natural daylight. The walls here were neatly plastered, and the doors more ornamental. "Getting near the high brass," murmured Chamberlin. The last hall was terminated by a window and balcony, beyond which the green of a distant hillside could be seen. Before we reached this, however, our guide stopped at a heavy aluminum door and directed us into a sort of ante-room, occupied by uniformed guards and a male receptionist. A few words were exchanged in Japanese, and the guards quickly and expertly frisked us, although this had already been done once. This ceremony over, another door was opened and we were admitted to a large and sunny office, whose big windows gave a panoramic view of the whole crater. Our eyes were so dazzled by the sudden burst of light, and our curiosity was so great to see that fantastic place by daylight, that we did not at once see the man who sat behind a desk opposite the windows, watching us with an expression of high amusement. Baker first noticed him. "Phobat Rau! So you're back of this, after all!" The other stood up. He was a short man, evidently Burmese, and wore a tan military uniform. His smile revealed a bonanza of gold teeth, while his thick lensed spectacles glittered in the brilliant sunshine streaming in through the windows.
