Unmistakably, it was a structure made of many square blocks of stone fitted together to form a section rising into the air from a foundation. Weber flashed his light around. "It ends here." The men hesitated to go around. What could this enigmatic wall be doing on this frigid world? The instruments showed the temperature to be many hundred degrees below zero Fahrenheit. What beings could have built this great wall? What could it mean? But at last they did go around the edifice, flashing their lights before them. And nearly collapsed from the shock of what they saw: a broad paved street on which bordered many stone houses whose glass windows reflected the dim glow of the stars above. The tiny sun cast a faint illumination on it all. "People!" gasped Mullins. There were. Standing on the streets and in the doors of the houses were the dim figures of men. Unmistakably human in form. "They're not alive," observed Rokesmith. "At least, they are not moving," replied Barth quickly. "Come on, then. Why are we waiting? Are you afraid of a lot of statues?" Captain Wanderman suited action to his words as he strode forward, stopping directly before the first of the standing figures. He cast his beam over it from head to foot. Unmistakably, it was a man. Clad in clothes and undeniably human. Its features were perfectly normal, bore the flush of life. The feet and entire body were set in attitude as if in the act of taking a step. But it was motionless. "Some statue!" breathed Opp. "I would swear it was a real man." "It is a real man," said Barth, softly. He bent close to the face. "It has the pores and tiny hairs that can only be on a true body." "Then he must have been alive once," murmured Weber. "What do you suppose happened to him? Is he petrified or only frozen solid?" "Frozen, I think," said Barth. "Yet, it is very strange. His flesh is still soft and resilient; it is not natural." "A land of frozen people!" Captain Wanderman's words struck a chilling note in all of them. Quickly they investigated the other figures. Some men, some women, some old, some young. All kinds and types; all apparently had been frozen solid in the middle of their normal activities. None showed any sign of being aware that death had struck. When the terrible freezing occurred it must have happened so swiftly, instantaneously, as to have caught all unaware. They moved on, saying little. There was that same eerie atmosphere that one finds in a wax museum while passing about among the realistic but silent and motionless figures of apparently ordinary people. Add to that the grim knowledge that the figures they now saw had been alive, that in effect the explorers were in a monstrous, planet-wide graveyard.
