"Speak, Garvey, Speak!"A Follower Recalls a Garvey Rally
The Jamaican-born Marcus Garvey, a brilliant orator and black nationalist leader, turned his Universal Negro Improvement Association (UNIA) into the most important black organization in the United States in the early 1920s. Garvey's speeches often drew huge audiences, and stories of Garvey's stubborn resistance in the face of white hostility proliferated among his supporters. In an oral history interview, devotee Audley Moore remembered the Jamaican's defiant behavior at a rally in New Orleans c
Slumming Among the Unemployed: William Wycoff Studies Joblessness in the 1890s
Even before the 1890s depression struck with devastating force in 1893, large numbers of jobless men and women competed in tight labor markets and faced homelessness. One of the best first-hand descriptions of "what it is to look for work and fail to find it" comes from political economist Walter Wycoff's two-volume study of The Workers: An Experiment in Reality, first published in 1899. Wycoff had abandoned his studies at Princeton to seek a more concrete appreciation of social problems. His re
Making the Atlanta Compromise: Booker T. Washington Is Invited to Speak
On September 18, 1895 Booker T. Washington, the noted African-American educator who was born a slave in 1858, spoke before the Cotton States and International Exposition in Atlanta. His Atlanta Compromise address, as it came to be called, was one of the most important and influential speeches in American history. Acutely conscious of the narrow limitations whites placed on African Americans' economic aspirations, Washington stressed that blacks must accommodate white people's--and especially sou
"Genesee Had Railroads": Kenneth Platt Recalls the Importance of the Railroad to Late Nineteenth-Cen
The penetration of the railroads into the West in the late nineteenth century had a profound impact on local economies. For a period of ten years in the 1880s the Latah County, Idaho town of Genesee experienced this phenomenon. One town boomed while its neighbors languished in economic isolation, largely as a result of the rail station in Genesee. In this oral history interview, Kenneth Platt described the railroad's impact on Latah County.
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
How Much do you Weigh on Distant Planets?
Students in the middle level solar system activity will study the effects of gravity on the planets of the Solar System. They will view movies from the lunar Apollo missions, calculate their own weight on other planets, and propose what they might weigh on newly discovered planets around other stars.
Atmosphere Applet: This program lets you study how the properties of the atmosphere change with altitude. You can study the atmosphere of either the Earth or Mars. The equations used in this program are taken from the ICAO standard day model for the Earth and from some curve fits of the Martian atmosphere gathered by the Global Surveyor spacecraft. Using the airplane graphic you can select an altitude, or you can type an altitude into the input box. The program instantly outputs a selected pro

A Text-Book of the History of Painting
The object of this series of text-books is to provide concise teachable histories of art for class-room use in schools and colleges. The limited time given to the study of art in the average educational institution has not only dictated the condensed style of the volumes, but has limited their scope of matter to the general features of art history. Archæological discussions on special subjects and æsthetic theories have been avoided. The main facts of history as settled by the best authorities
Collaborative Work During Interventional Radiological Procedures Based on a Multicast Satellite-Terr
Collaboration is a key requirement in several contemporary interventional radiology procedures (IRPs). This work proposes a multicast hybrid satellite system capable of supporting advanced IRP collaboration, and evaluates its feasibility and applicability. Following a detailed IRP requirements study, we have developed a system which supports IRP collaboration through the employment of a hybrid satellite-terrestrial network, a prototype multicast version of wavelet based interactive communication

Tonto National Monument: Saving a National Treasure
tells the story of the Salado people, who thrived in the Arizona valley where Tonto Creek joins the Salt River (1050-1450 AD). The Salado culture combined customs of several American Indian groups. They channeled the river to create farmland in the desert. They built Pueblo-style buildings. They left no written records. This monument, established in December 1907, was among the first sites protected under the Antiquities Act of 1906.
