On the third day of their journey, the trail led upward, into a range of bleak and rocky hills. A few mean huts were the only signs of human habitation. Then, as they rounded a bend in the trail which at this point clung to the face of a cliff, they saw the answer to a mystery that had puzzled the civilized world for two years. It was the wreck of the space-ship _Stardust_. She lay at the foot of a cliff across the valley, her steel and duralite hull still gleaming brightly through the thick green creepers that had grown up around it. Even from this distance Gerry could see the hopelessly crumpled rocket-tubes at the stern, and the gaping holes where plates had been ripped away to make the submarine that had brought them out of the city of Larr. "So that was the end of the _Stardust_!" Gerry muttered. "I wonder what happened to her crew!" "We'll probably find out soon enough!" McTavish replied grimly. "I'll bet all the gold in Savissa against an empty rocket-oil tin that we're headed for the same fate right now." "Poor devils--I suppose the Scaly Ones did get them. I never liked Walter Lansing, as you know, but I could have wished him better luck than this!" At last they crossed the hills and saw a broad valley before them. Dim and snow-capped mountains notched the yellow sky on the far side of the Valley. A river wound through the plain, and on the shore of the saffron waters of a mighty lake they saw the gray walls of a city. Toll, the reptilian captain, pointed across the valley. "Yonder lies the city of Vaaka-hausen. Soon you will stand before the Lord Lansa, and then," he added with a grim and ghoulish humor, "neither I nor anybody else will be bothered with you any more." The countryside immediately around the city of the Scaly Ones was better kept and more cultivated than what they had seen of the rest of Giri-Vaaka. There were a number of small villages. Then they passed in through the walls, gray stone ramparts that seemed to be very old and were in poor repair. The muzzles of heavy caliber gas-guns peered over the battlements here and there. The crowds in the streets stared curiously as Toll led his prisoners toward the center of the city. Tall reptile men swaggered through the crowds with their swords slung on their hips, but the shorter Green Men were in the great majority. Most of them, men and women alike, stared at the captives without any particular sign of emotion. This gray and crowded city of Vaaka-hausen had none of the atmosphere of pleasant friendliness that Gerry had noticed in Larr. It seemed a place of fear and oppression. * * * * *
