At the time, the XIT was the world's largest ranch. It stretched for two hundred miles from the top of the Panhandle to Lubbock. It averaged 27 miles in width. Its greatest width was fifty miles. For comparison, the ranch was about twice as large as the state of Rhode Island. This book tells of life on the XIT Ranch as recorded on an almost daily basis by Mrs. Cordia Sloan Duke, wife of an XIT division manager, Robert L. Duke. It is illustrated with photographs, and a map.
