the history of II Corps (1886) as well as a biography of General Winfield Scott Hancock (1884). Walker was elected Commander of the Massachusetts Commandery of the Military Order of the Loyal Legion of the United States in 1883 was also the president of the National Military Historical Association. Postbellum activity By late spring 1865, Walker regained sufficient strength and began to assist his father by lecturing on political economy at Amherst as well as assisting him in the preparation of The Science of Wealth. He also taught Latin, Greek, and mathematics at the Williston Seminary in Easthampton, Massachusetts until being offered an editorial position at the Springfield Republican by Samuel Bowles. At the Republican, Walker wrote on Reconstruction era politics, railroad regulation, and representation. 1870 Census While his editorial career was moving forward, Walker called upon his own as well as his father's political contacts to secure an appointment under David Ames Wells as the chief of the U.S. Bureau of Statistics and deputy special commissioner of Internal Revenue in January 1869. On January 29, 1869, Major General J.D. Cox, who had also previously served in McClellan's army and was currently the Secretary of the Interior under President Grant's administration, notified the twenty-nine-year-old Walker that he was being nominated to become the superintendent of the 1870 census. After he was confirmed by the Senate, Walker sought to strike a moderate reformist position free from the inefficient and unscientific methods of the 1850 and 1860 censuses; however, the required legislation was not passed and the census proceeded under the rules governing previous collections. Among the problems facing Walker included a lack of authority to determine, enforce, or control the marshals personnel, methods, or timing all of which were regularly manipulated by local political interests. Additionally, the 1870 Census would not only occur five years after Civil War but would also be the first in which emancipated African Americans would be fully counted in the census. Owing to the confluence of these problems, the Census was completed and tabulated several months behind schedule to much popular criticism, and led indirectly to a deterioration in Walker's health during the spring of 1871. Walker took leave to travel to England with Bowles that summer to recuperate and upon return that fall, despite an offer from The New York Times to join their editorial board with an annual salary of $8,000 ($ in 2016),
