"We Have Got a Good Friend in John Collier": A Taos Pueblo Tries to Sell the Indian New Deal
The Indian Reorganization Act of 1934, which became known as the Indian New Deal, dramatically changed the federal government's Indian policy. Although John Collier, the commissioner of Indian affairs who was responsible for the new policy, may have viewed Indians with great sympathy, not all Native Americans viewed his programs in equally positive terms. Antonio Luhan, the husband of the wealthy writer Mabel Dodge Luhan and a Taos Pueblo Indian, was a friend and supporter of John Collier. In th

"We Are Literally Slaves": An Early Twentieth-Century Black Nanny Sets the Record Straight
In folklore the black nursemaid was seen as a dutiful, self-sacrificing black woman who loved her white family and its children every bit as much as her own. Yet the popular images of the loyal, contented black nursemaid, or "mammy," were unfortunately far from the reality for the African-American women who worked in these homes. In 1912 the Independent printed this quasi-autobiographical account of servant life, as related by an African-American domestic worker, which dispelled the comforting "

Dissatisfied With the Lives They Live: Farm Women Describe Their Work in a 1913 U.S. Department of A
Statistics on women's work in the early 20th century were invariably misleading: most women worked but only a minority were formally in the wage labor force. Nowhere was the discrepancy between the domestic ideal and the reality of women's work lives wider than in rural America. In 1913 the U. S. Department of Agriculture decided to investigate and document the lives of farm woman they discovered a vast reservoir of discontent. The report, reproduced here, was culled from letters responding to a

Slowing the Flow
In this hands-on OLogy activity, kids learn how the mammalian diving reflex works to help both land and sea mammals survive in cold water. The activity begins with a kid-friendly look at the way all mammals' bodies respond similarly when exposed to cold water. The illustrated, step-by-step directions show kids how to test the effect cold water has on their circulation by measuring their pulse before and after they plunge their faces into icy water. It includes a fast fact about how the mammalian
