Evolution

The evil and greedy Wendell Crowe begins to play hardball with Miss Harper by threatening to having her teaching license revoked unless she stops holding after-shift reading classes for the miners. But it takes some intervention by Ned to play on the little humanity and feelings Mr. Crowe has to let Miss Harper continue teaching. Meanwhile, Nellie's laundry business picks up in full force, while Willie is overwhelmed with helping her, as well as keeping time for his delivery job and schoolwork. It leads to Mollie and Angus playing a mean practical joke on Willie for neglecting them by agreeing to help him fix his school science project. Also, Nellie thinks about taking a job as a secretary for Mr. Frawley after a neighbor, named Flora, turns it down.
