By late spring 1865, Walker had regained sufficient strength and began lecturing on political economy at Amherst and assisting his father in the preparation of his new book,
The Science of Wealth. He also taught Latin, Greek, and mathematics at
Williston Seminary 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 superintendent In January 1869, while his editorial career was moving forward, Walker secured an appointment as the chief of the United States Bureau of Statistics and deputy special commissioner of Internal Revenue. On January 29, Secretary of the Interior
Jacob D. Cox notified Walker that he was being nominated as superintendent of the
1870 census. After he was
confirmed by the
Senate, Walker sought to strike a moderate, reformist position. However, proposed reform legislation was not passed, and the 1870 census proceeded under the rules governing previous collections, which Walker deemed inefficient and unscientific. Walker lacked authority to determine, enforce, or control the personnel, methods, or timing of the census, all of which were regularly manipulated by local political interests. The 1870 census also posed the challenges of post-war reconstruction and would be the first in which
emancipated African Americans would be fully counted in the census. The census was completed and tabulated several months behind schedule to much popular criticism, which led indirectly to a deterioration in Walker's health during the spring of 1871. Walker took leave to travel to England with Bowles in summer 1871 to recuperate. Walker continued to work on the 1870 census for several years, culminating in the publication of the first
Statistical Atlas of the United States, which was unprecedented in its use of visual statistics and maps to report the census results. The
Atlas won Walker praise from the secretary of the
Smithsonian Institution and a first-class medal from the
International Geographical Congress.
Commissioner of Indian Affairs Upon his return to the United States in fall 1871, Walker declined an offer to join
The New York Times editorial board with an annual salary of $8,000 ($ in ) and accepted an offer from Secretary of the Interior
Columbus Delano to become the
United States Commissioner of Indian Affairs. The appointment permitted Walker to maintain his federal responsibilities as census superintendent, despite appropriations for the position ending, and offered a political opportunity to improve on the administration of Commissioner
Ely S. Parker, who left office under a cloud of scandal. Walker served only briefly as Commissioner of Indian Affairs, resigning on December 26, 1872, to take a faculty position at
Yale University, after considering a return to editorial journalism and even briefly entertaining the idea of manufacturing shoes with his brother-in-law in North Brookfield. During his service, he collected demographic information on native tribes and on the history of conflict and treaties, which he published as a book titled
The Indian Question in 1874. More than half of the book is dedicated to an appendix with descriptions of over 100 tribes which he describes as including 300,000 natives, the majority of which were living on existing government reservations.
The Indian Question weighs the reservation system as it existed in 1874 against full assimilation and United States citizenship. He argues that the reservation system is failing due to illegal incursions into the native lands, but counters that immediate full assimilation damages native culture, quality of life, and dignity. Walker concluded that assimilation must be the ultimate end goal, but that assimilation required protection of the indigenous population “under the shell of the reservation system.” He proposed detailed solutions, including consolidation of the existing reservations into fewer larger units, laws and enforcement against settler incursions, government-sponsored training programs within reservations, and federal financial support based on an endowment and not annual appropriations. Walker supported reparations for past actions toward Native Americans, arguing, “We may have no fear that the dying curse of the red man, outcast and homeless by our fault, will bring barrenness upon the soil that once was his, or dry the streams of the beautiful land that, through so much of evil and of good, has become our patrimony; but surely we shall be clearer in our lives, and freer to meet the glances of our sons and grandsons, if in our generation we do justice and show mercy to a race which has been impoverished that we might be made rich.” Walker elevated the treatment of the natives as one of the great issues of the time, arguing, “The United States will be judged at the bar of history according to what they shall have done in two respects: by their disposition of negro slavery and by their treatment of the Indians.”
Other work While working at Yale in 1876, Walker was recruited by
Henry Adams as editor-in-chief of the
Boston Post, after Adams failed to recruit
Horace White and
Charles Nordhoff for the position. In spring of the same year, Walker was nominated by the
Republican Party for
Secretary of the State of Connecticut on a reform platform, but ultimately lost to Democratic incumbent Marvin H. Sanger by a margin of 7,200 votes out of 99,000 cast. In the summer, Amherst faculty attempted to recruit Walker as president of Amherst, but the position went instead to the
Julius Hawley Seelye to appease more conservative trustees. In 1876,
Charles Francis Adams Jr. appointed Walker as the chief of the Bureau of Awards at the
Centennial Exposition in
Philadelphia. In contrast to global expositions in Europe, which were fraught with national factionalism and a superabundance of awards, Walker imposed a much leaner operation, replacing juries with judges and awarding prizes more selectively. His work on the exposition won Walker formal international recognition. He received honors from Sweden, Norway and Spain and was invited to serve as assistant Commissioner General at the
1878 Paris Exposition. The exposition greatly increased Walker's interest in technical education and introduced him to
Massachusetts Institute of Technology (MIT) president
John D. Runkle and treasurer
John C. Cummings. The 1880 census notably suggested population of the Southern states had improbably increased from the 1870 census; an investigation revealed that the 1870 figures had been inaccurately enumerated. Walker publicized the discrepancy, even though it effectively discredited the accuracy of his 1870 work. Walker also used the position as a
bully pulpit to advocate for the creation of a permanent
United States Census Bureau, to ensure professional statisticians could be trained and retained and that the information could be widely disseminated. The 1880 census was again delayed as a result of its size and subject to praise and criticism on its comprehensiveness and relevance. The 1880 census resulted in the publication of twenty-two volumes. It was popularly regarded as the best census up to that time and established Walker's reputation as the preeminent American statistician. Following Garfield's victory in the
1880 presidential election, there was wide speculation that Walker would be appointed
Secretary of the Interior, but Walker instead accepted the offer to become MIT president in spring 1881. ==Academic career and views==
