He now became interested in a faint path leading towards the lake of molten rock. It appeared too large for the Bears and not too old. Besides, he reasoned, what would any living creature want at the lake? He followed the path to a high promontory overlooking the lake. He stood there, fascinated by the thought of the terrific energy necessary to melt the planet's substance itself. There was a movement against his legs and he looked down. There was the same Teddy Bear that had followed him, rather than stay with its fellow creatures. The display of affection almost led him to lean over and stroke the beast. However he remembered his resolve barely in time and snapped erect. The desire disappeared immediately and he glared down at the Bear. It appeared saddened and sat back on its haunches, searching his face with button-like black eyes. Again Boyette turned to the lake, reminded of the old swimming hole back home. Many a time he'd stood on its high bank, similar to this, then leaped far out to join the rest of the gang. It looked so peaceful below, he thought. If one were to leap or fall, there'd be no pain. And to be released from the worries of life in such beautiful surroundings, who knew what wonderful existence might lie in store for him? He moved closer to the edge and tensed, ready to leap. A lingering doubt crept into his mind, struggling to overcome the urge to jump. Would the others follow him? He forced his head around and saw them cavorting with the Teddy Bears on the grass below. The one that had followed him was standing erect, eagerly watching his every move. His resolve to consider every action was smothered under. Once again he teetered on the lip of the rock, trying to edge back but finding that his muscles refused to obey. Fragments of thought flitted through his mind, each being erased after a brief flash. All at once he remembered the Teddy Bear that had become so frantic at the tobacco that had fallen on it. Accustomed to analytical approaches to problems in the lab he suddenly wondered if the creatures were capable of implanting suggestions in human minds? The mental struggle caused perspiration to break out in beads over his forehead. He slowly dug a heel into the dirt, then straining, scattered soil into the face of the animal behind him. Instantly it seemed as if bonds had been cut from his limbs and he recoiled in horror from the bubbling rock below. Boyette shoved by the animal, frantically brushing dirt from its face and hide. It was now quite evident that the creatures needed full concentration to work their will. He also determined not to let himself fall under their power again. At least he was convinced where the expedition's peril lay. He headed for the ship, determined to act now. Intent on his own thoughts he didn't see the figure that loomed up before him. A hearty voice roared, "Well, Doctor, why the gloomy look on such a fine day?"
