A third day in Mary Carrow's school by Anonymous is a didactic children’s Sunday-school tale written in the mid-19th century. It presents a gentle picture of rural schooling and moral formation, likely aimed at young readers and their families, focusing on everyday lessons, play, nature study, and simple Christian teaching. The story follows teacher Mary Carrow through one full school day. She rises early for prayer and neat housekeeping, then welcomes a small class—among them Charles and Harry Linn, Carry Deacon, Eddy and Lily Forester, Susan Field, and Ellen Raby. A geography lesson grows into a clear talk about how farmers, merchants, mechanics, authors, and doctors all depend on one another. During recess the children race to fly Charles’s kite, which splashes into a stream, and Mary turns the mishap into cheerful instruction before leading a meadow ramble and a first botany lesson on roots, stems, leaves, and how plants live. In the afternoon sewing session, she mixes reading, spelling, and simple arithmetic with two stories about loyal dogs—a blind beggar’s guide and Cairo, who protects Kitty Green in a storm. The day closes outdoors with Bible readings about Jesus guiding people back to God, a brief talk on temptation and the Saviour’s care for “little lambs,” and warm goodbyes, leaving the children safe, happy, and eager to return.
