Then with a strange wild roar the people rushed for us. Racing on their hands they came. Rocks and missiles whizzed about us. An arrow whirred by my head and struck quivering in a strut. But now we were rising rapidly. We were looking down upon the maddened hosts, their arrows and sling-flung stones were striking the under surface of the fuselage and wings. We were safe at last. A moment more and we would be above the crater rim. A sudden exclamation from Hazen startled me. I glanced up. Straight ahead rose the precipitous mountain side above the quarry. To clear it we must ascend far more rapidly than we were doing. “Must have splintered the blades!” jerked out Hazen. “She’s not making it. Can’t swing her. Rudder’s jammed. Heave out everything you can find. Hurry or we’ll smash!” Before us loomed the ragged, rocky wall. We were rushing to our doom at lightning speed. At Hazen’s words I grasped whatever I could find and tossed it over the side. A box of provisions, a roll of tools, a leather jacket, a thermos bottle, canteens, an automatic pistol and a cartridge belt all went. I glanced up. We were rising faster. A few pounds more overboard, a few feet higher and we would be clear. Was there anything else I could throw out? Frantically I searched. I saw a canlike object resting on a frame. Spare gasoline I decided, but fuel was of no value now. With an effort I dragged it out. I lifted it and hurled it over. With a sudden jerk the plane sprung upward. There was a terrific muffled roar from below and with barely a yard to spare we rose above the crater rim. “Lord, you must have dropped that old bomb!” cried Hazen. “The concussion jarred the rudder free.” I glanced over the side. Far beneath, a cloud of smoke and dust was drifting slowly aside exposing the aqueduct, broken, smashed and in ruins. From the opening in the mountain side a mighty stream of water was roaring in a rushing, tearing torrent. The bomb had landed squarely in the quarry. The aqueduct had fallen, the shock had let loose the gates of the lake and the whole vast crater reservoir was pouring in a mighty flood across the valley. In a wide arc Hazen swung the plane about. “Poor devils!” he muttered as we soared above the doomed city. Already the green plain was shimmering with the glint of water. We could see the frantic, frenzied people running and scrambling up their ladders. Again we wheeled and circled far above them and now only the roof tops of the houses were above the flood. Presently these too sank from sight and above the sunlit waters only the sacrificial stone remained. “It’s all over!” exclaimed Hazen, and heading northward we sped beyond the encircling mountain sides.
