Danny listened day in and day out to Pop Dunphy's stories, hanging on every word. But when Pop tells him about El Conquistador, a lost gold mine, Danny disappears, returning one day from his attempts to find that mine seriously injured. When Pop is confronted by Danny's parents, Pop, holding a "magic" watch given to him by General Custer, fades away, then re-appears. He tells them that he was suddenly back at his mine being attacked by Indians before suddenly coming back....loaded with gold nuggets!; Matt Wayne awakes in the desert and re-traces his steps to a wrecked spacecraft that he once commanded in an expedition he led to Mars. Entering, he finds the radio dead and crewmates missing. He searches for them, his oxygen running low and he stops to rest when hairy things in the crewmen's helmets approach him, giving him a red rock. He is taken to another area where he spots Phobos, a moon of Mars. Its light plays on him and he recovers his strength and can breathe without his faceplate...but he changes, like the others. Then he awakes in a hospital, and is introduced to his crew.; While checking cables beneath the streets of downtown New York, Charley Paine is trapped by a flash flood. He spots a door in the tunnel wall and goes through it, emerging in a civilization long since past. Taken before a Governor, he is told the underground town was built in 1660 to hide from the tyrant, Peter Styvesant of Nieuw Amsterdam. Charley is imprisoned, but uses his flashlight to blind a guard and escape, making it back to the tunnel entrance where he is rescued. When his rescuers look into the passage he emerged from, all they see are human bones!
