What Katy Did is an 1872 children’s book written by Sarah Chauncey Woolsey under her pen name Susan Coolidge. It follows the adventures of a twelve-year-old American girl, Katy Carr, and her family who live in the fictional lakeside Ohio town of Burnet in the 1860s. Katy is a tall untidy tomboy, forever getting into scrapes but wishing to be beautiful and beloved. When a terrible accident makes her an invalid, her illness and four-year recovery gradually teach her to be as good and kind as she has always wanted. I was sitting in the meadows one day, not long ago, at a place where there was a small brook. It was a hot day. The sky was very blue, and white clouds, like great swans, went floating over it to and fro. Just opposite me was a clump of green rushes, with dark velvety spikes, and among them one single tall, red cardinal flower, which was bending over the brook as if to see its own beautiful face in the water. But the cardinal did not seem to be vain.
