Abner Charles Powell (December 15, 1860 in Shenandoah, Pennsylvania – August 7, 1953 in New Orleans, Louisiana) was a Major league baseball player who was a member of the Washington Nationals of the Union Association in 1884. He later played for the Baltimore Orioles and the Cincinnati Red Stockings in 1886. He also managed and owned several teams.
Powell was more famous, however, for innovations that changed baseball. In 1887, Powell came up the idea of using an infield tarpaulin so that fields could be ready immediately after rain storms.]citation needed[ He also introduced Ladies Day, with the first scheduled recurring game on April 29 that same year.]citation needed[ The idea was to create an environment in the stands free of unsavory characters and conduct, as well as to make baseball a family oriented event. This practice is still in place today. His most important innovation, however, was the introduction of the rain check, which added a perforated stub to tickets so that fans could attend a make-up game if the scheduled game was cancelled due to rain.]citation needed[
The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, a federal district, and various overseas extraterritorial jurisdictions. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the US mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms.
