The Dictionary Project is a post-a-day exploration of The Century Dictionary and Cylopedia, a twelve-volume set printed in New York in 1901. The Project runs from October 1, 2014 to September 30, 2015, and matches volume numbers to calendar months. Volume X is The Atlas, and today is Day 4.
Welcome to Oklahoma and Indian Territory, as it looked in 1897. According to Wikipedia, the two would be combined into a single state in 1907, six years after this Atlas was published, ten years after this map was drawn, and 73 years after this particular territory was created (if I understand the Wikipedia article linked up there correctly) under the Indian Intercourse Act. (How aptly named!)
