The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)

Some vols. include supplemental journals of "such proceedings of the sessions, as, during the time they were depending, were ordered to be kept secret, and respecting which the injunction of secrecy was afterwards taken off by the order of the House."

This monograph was begun during my residence as Rogers Memorial Fellow at Harvard University, and is based mainly upon a study of the sources, i.e., national, State, and colonial statutes, Congressional documents, reports of societies, personal narratives, etc. The collection of laws available for this research was, I think, nearly complete; on the other hand, facts and statistics bearing on the economic side of the study have been difficult to find, and my conclusions are consequently liable to modification from this source. The question of the suppression of the slave-trade is so intimately connected with the questions as to its rise, the system of American slavery, and the whole colonial policy of the eighteenth century, that it is difficult to isolate it, and at the same time to avoid superficiality on the one hand, and unscientific narrowness of view on the other. While I could not hope entirely to overcome such a difficulty, I nevertheless trust that I have succeeded in rendering this monograph a small contribution to the scientific study of slavery and the American Negro.' William Edward Burghardt "W. E. B." Du Bois (1868 – 1963) was an American sociologist, historian, civil rights activist, Pan-Africanist, author, writer and editor. Born in Great Barrington, Massachusetts, Du Bois grew up in a relatively tolerant and integrated community. After completing graduate work at the University of Berlin and Harvard, where he was the first African American to earn a doctorate, he became a professor of history, sociology and economics at Atlanta University. Du Bois was one of the co-founders of the National Association for the Advancement of Colored People in 1909.

The Colorado River had one of the most unique fish communities in the world. Seventy-five percent of those species were found nowhere else in the world. Settlement of the lower basin brought dramatic change to both the river and its native fish. Those changes began more than 120 years ago as settlers began stocking nonnative fishes. By 1930, nonnative fish had spread throughout the lower basin and replaced native communities. All resemblance of historic river conditions faded with the construction of Hoover Dam in 1935 and other large water development projects. Today, few remember what the Colorado River was really like. Seven of the nine mainstream fishes are now Federally-protected as endangered. Federal and state agencies are attempting to recover these fish. However, progress has been frustrated due to the severity of human impact. This report represents testimony, old descriptions, and photographs describing the changes that have taken place in hopes that it will provide managers, biologists, and the interested public a better appreciation of the environment that shaped these unique fish.
