Dead End in Norvelt
Dr. Metz and Mrs. Woodcliff
Dr. Metz is the town doctor, and—Mrs. Woodcliff is his receptionist. Dr. Metz recommends that Jack have his nose fixed and eat iron-fortified cereal to help his nosebleeding condition (7.18). He's a man of science: he shows Jack how iron-rich the cereal is by crushing some up and holding a magnet to it, drawing out the iron flecks (7.18).
But he's also a man of business: Dr. Metz will only take cash in exchange for his services, and not any of the home-canned fruits or vegetables that Jack's Mom offers to exchange. Dr. Metz represents the future of Norvelt: less community; more cold, hard cash.
