Caroline stays with Mary who suddenly needs another operation. Charles leave and take on a high risk job to pay for the operation for Mary and Mr. Edwards goes with him. They take a job as a couple of Powder Monkeys making a tunnel for the railroad. But safety is far at the back of Charles' mind as he takes risks, refusing to stop even when a funeral of a Chinese worker takes place. This rush inevitably causes a cave-in where Charles and Harris are buried.
