Caroline Bond Day occupied a variety of jobs following her graduation from Radcliffe. In 1919 in New York City, she worked with black soldiers and their families in support and relief services. Day also found work as a student secretary of the National Board of the
YMCA in
Montclair, New Jersey. After her marriage to Aaron Day in 1920, she and her husband moved to
Waco, Texas, where she was Dean of Women at
Paul Quinn College for a year, and spent another year as head of the English Department at
Prairie View State College. In 1922, the Days moved to
Atlanta, Georgia, where she then taught English and drama at the same university she first attended,
Atlanta University. She taught there until 1929 while also publishing some essays and short stories, such as her famous tale,
The Pink Hat. Between the years 1927 and 1930, Day was on leave to take some courses in anthropology at Radcliffe, and also to continue the research that she began with
Earnest Hooton in her senior year at Radcliffe in 1919. While working on her research in Hooton's lab, Day was able to collect and analyze sociological and physiological information on 346 families, including her own. These results were published in 1932 by
Harvard's
Peabody Museum, named "A Study of Some Negro-White Families in the United States". After a while, Day took a break from the project due to being exhausted and a
rheumatic heart condition. She returned to teaching in Atlanta University and taught English and was also "said to have given the first class in anthropology ever offered in Atlanta University". Day and her husband then moved to
Washington D.C. in 1930 where she then taught English at
Howard University for two years, following her job in social work as settlement-house supervisor in Washington D.C., and then as general Secretary of the
Phillis Wheatley YMCA. Finally in late 1939, the Days moved to Durham, North Carolina, where Day taught English and drama at North Carolina College for Negroes (now called
North Carolina Central University), but then retired that same year due to her heart illness. ==Death and archive==
