“The two demons are going fast, but we will reach the edge before they can catch us. God help us, another monster and straight ahead. We can not go that way and must turn south or north. No, not north for I see two coming from that direction. We are nearly surrounded and our only hope is south. I see the edge south, but it is a mile farther away than west. But we will make it. I don’t see any of the demons coming from that direction. Our machine is roaring at full speed, but we are not making over fifty or sixty miles in this rarefied air. The demons of this upper air are flying twice as fast and now there are nearly a dozen close on our trail and swiftly gaining.... We are near the edge and our danger is over. A minute more and we would have been lost, for now there are two monsters in front of us. We are surrounded, but we will reach the edge and will head down like a bullet before they can get near enough to head us off. Their screams are bringing other monsters from all directions. “Just passed one of those hideous flying devil-fish and see another ahead and above us. We are just at the edge and are tipping down for our long dive. Will be with you in a few---- Dex, Dex, look out for the devil-fish. For God’s sake, look, Dex---- Oh, God, too late-- We are done. Our propeller is shattered, we are falling. Look out below-- No, we have fallen on the edge of the island. We are tearing through. No we have stopped. God, we are in a fix. The devil-fish flung itself at us and into our propeller and wrecked it and blocked the controls and we fell straight down. We are within a few hundred feet of the edge, the weight of the machine has sunk us until we rest in a sloping crater about fifty feet deep. The monsters are arriving and flying in circles above us. Our motor is quiet and when we raise our receivers, the screams and snapping of their giant beaks almost deafen us. Our only hope now is to reach the edge and trust ourselves to our safety parachutes.” For several minutes the horns were quiet and the people jammed around them listening for further word from the two men in the void above. They whispered together in low under-tones and every minute or so their eyes traveled upward in an attempt to pierce the blind of the miles distance. But in vain. At last--it seemed hours, though it was only a few minutes--the voice came again.
