"Why don't you persuade him to stay here? Mayfield's a darn good place to live." "I've tried already, but he says that when a man is grown he has too many things to hold him to the place he's always known. He has promised, however, to let me come back if I want to, after I finish the university at home." "That would be nice." Ken turned away, keeping his eyes intently on the road. There was nothing else he could say. He drove slowly up the long grade of College Avenue. His family lived in an older house a block below the brow of College Hill. It gave a pleasant view of the entire expanse of the valley in which Mayfield was situated. The houses of the town ranged themselves in neat, orderly rows below, and spread out on the other side of the business section. In the distance, north and south, were the small farms where hay and dairy stock and truck crops had been raised since pioneer times. "I'll miss this, too," said Maria. "It's beautiful." Ken wasn't listening to her, however. The car had begun to sputter painfully as it took the curve leading off the avenue to Linwood Street where Ken lived. He glanced at the heat indicator. The needle was almost at the boiling point. "For Pete's sake! The water must have leaked out of the radiator." Ken pulled the car to the curb in front of the house and got out, leaving the engine idling. He raised the hood and cautiously turned the radiator cap with his handkerchief. A cloud of steam shot out, but when he lifted the cap the water was not quite boiling, and there was plenty of it. Maria came up beside him. "Is something wrong?" "You've got me there. The radiator's clean. The pump isn't more than two months old. I checked the timing last Saturday. Something's gone sour to make her heat up like that." From across the street, his neighbor, Mr. Wilkins, approached with a grin. "Looks like the same thing hit us both. Mine started boiling as I came up the hill tonight. It's got me stumped." "The circulation must be clogged," said Ken. "Either that or the timing has slipped off. That's all it could be." "Those were my ideas, too. Both wrong in my case. Let me know if you get any other bright ones." He moved off with a pleasant wave of his hand. "It will cool," said Ken to Maria. "By the time you're ready to leave I'll be able to drive you home." "I wouldn't want you to damage your car. I can walk." "We'll see." He led her around the house. In the center of the backyard loomed the high, round dome of his amateur observatory. It was Ken's personal pride, as well as that of the members of the Mayfield High Science Club, who had helped build the shell and the mountings. The club used it every Thursday night when the seeing was good.
