Green Stone Messages   During this week's episode of Kung Fu: The Legend Continues Which I was watching last night on tape, Caine gave a greenish, smooth, oval stone With a stylized snake on it To a young psychic girl, Explaining that jade is a powerful stone And that snakes are powerful creatures   Caine showed the girl his own stone pendant And told her that with the help of their stones They could communicate with each other   Later she was in grave danger And used her stone to summon Caine, Who rescued her on a rooftop After clamboring lizardlike up a sheer wall (A la Don Genaro in Castaneda's books)   ***   Later in the evening I resumed reading Sonic Boom Trap, A Tom Swift, Jr. book I had recently acquired   Tom presents a young woman Whose life may be in danger A green cameo ring, Which controls a mobile robot Following her for protection   The ring has a stone in the center That she is to press To activate the robot's defenses   ***   Yesterday afternoon I was sweeping out the garage, Which I seldom do, When a shaft of light Speared my attention From the garage floor   A small chunk of broken glass, A bright, sparkling, green speck, Was set on fire by the setting sun's rays
