- Chester A. Arthur (Wikiquote)
Chester Alan Arthur (October 5, 1829 – November 18, 1886) was an American attorney and politician who served as the 21st president of the United States (1881–85); he succeeded James A. Garfield upon the latter’s assassination. At the outset, Arthur struggled to overcome a slightly negative reputation, which stemmed from his early career in politics as part of New York’s Republican political machine. He succeeded by embracing the cause of civil service reform. His advocacy for, and subsequent enforcement of, the Pendleton Civil Service Reform Act was the centerpiece of his administration.
- John Day River (Wikipedia)
The John Day River is a tributary of the Columbia River, approximately 284 miles (457 km) long, in northeastern Oregon in the United States. It is known as the Mah-Hah River by the Cayuse people. Undammed along its entire length, the river is the fourth longest free-flowing river in the contiguous United States. There is extensive use of its waters for irrigation. Its course furnishes habitat for diverse species, including wild steelhead and Chinook salmon runs. However, the steelhead populations are under federal Endangered Species Act (ESA) protections, and the Chinook salmon have been proposed for such protection.
