A graduate of the Maryland Institution for the Blind, Mary L. Day published a memoir in 1859 entitled Incidents in the Life of a Blind Girl. In this book, a sequel to her first, she recounts how she traveled throughout the country earning a living through the sale of her memoir. She also writes about meeting her future husband, visiting places of interest, and having numerous adventures on the road. The book closes with several essays on blindness and the education of the blind and with a collection of poems by blind authors.
