paragraph_text: The Rhine (Romansh: Rein, German: Rhein, French: le Rhin, Dutch: Rijn) is a European river that begins in the Swiss canton of Graubünden in the southeastern Swiss Alps, forms part of the Swiss-Austrian, Swiss-Liechtenstein border, Swiss-German and then the Franco-German border, then flows through the Rhineland and eventually empties into the North Sea in the Netherlands. The biggest city on the river Rhine is Cologne, Germany with a population of more than 1,050,000 people. It is the second-longest river in Central and Western Europe (after the Danube), at about 1,230 km (760 mi),[note 2][note 1] with an average discharge of about 2,900 m3/s (100,000 cu ft/s).

paragraph_text: High levels of precipitation cause the glaciers to descend to permafrost levels in some areas whereas in other, more arid regions, glaciers remain above about the 3,500 m (11,483 ft) level. The 1,817 square kilometres (702 sq mi) of the Alps covered by glaciers in 1876 had shrunk to 1,342 km2 (518 sq mi) by 1973, resulting in decreased river run-off levels. Forty percent of the glaciation in Austria has disappeared since 1850, and 30% of that in Switzerland.

paragraph_text: Bridgewater is a borough in Beaver County, Pennsylvania, United States. The population was 704 at the 2010 census. It is best known as the home of the Bruster's Ice Cream chain.

paragraph_text: Near Tamins-Reichenau the Anterior Rhine and the Posterior Rhine join and form the Rhine. The river makes a distinctive turn to the north near Chur. This section is nearly 86 km long, and descends from a height of 599 m to 396 m. It flows through a wide glacial alpine valley known as the Rhine Valley (German: Rheintal). Near Sargans a natural dam, only a few metres high, prevents it from flowing into the open Seeztal valley and then through Lake Walen and Lake Zurich into the river Aare. The Alpine Rhine begins in the most western part of the Swiss canton of Graubünden, and later forms the border between Switzerland to the West and Liechtenstein and later Austria to the East.

Djibouti occupies a total area of 23,200 km2 (8,958 sq mi). The state of Djibouti is predominantly inhabited by two ethnic groups, the Somali and the Afar people, the Somalis being the major ethnic group of the country.

paragraph_text: Between Bingen and Bonn, the Middle Rhine flows through the Rhine Gorge, a formation which was created by erosion. The rate of erosion equaled the uplift in the region, such that the river was left at about its original level while the surrounding lands raised. The gorge is quite deep and is the stretch of the river which is known for its many castles and vineyards. It is a UNESCO World Heritage Site (2002) and known as "the Romantic Rhine", with more than 40 castles and fortresses from the Middle Ages and many quaint and lovely country villages.

paragraph_text: Stagecoach was the first of many Westerns that Ford shot using Monument Valley, in the American Southwest on the Arizona -- Utah border, as a location, many of which also starred John Wayne. Scenes from Stagecoach, including a famous sequence introducing John Wayne's character the Ringo Kid, blended shots of Monument Valley with shots filmed on the Iverson Movie Ranch in Chatsworth, California, RKO Encino Movie Ranch, and other locations. Similar geographic incongruencies are evident throughout the film, up to the closing scene of Ringo (Wayne) and Dallas (Trevor) departing Lordsburg, in southwestern New Mexico, by way of Monument Valley.

paragraph_text: The Rhine emerges from Lake Constance, flows generally westward, as the Hochrhein, passes the Rhine Falls, and is joined by its major tributary, the river Aare. The Aare more than doubles the Rhine's water discharge, to an average of nearly 1,000 m3/s (35,000 cu ft/s), and provides more than a fifth of the discharge at the Dutch border. The Aare also contains the waters from the 4,274 m (14,022 ft) summit of Finsteraarhorn, the highest point of the Rhine basin. The Rhine roughly forms the German-Swiss border from Lake Constance with the exceptions of the canton of Schaffhausen and parts of the cantons of Zürich and Basel-Stadt, until it turns north at the so-called Rhine knee at Basel, leaving Switzerland.

paragraph_text: By the 6th century, the Rhine was within the borders of Francia. In the 9th, it formed part of the border between Middle and Western Francia, but in the 10th century, it was fully within the Holy Roman Empire, flowing through Swabia, Franconia and Lower Lorraine. The mouths of the Rhine, in the county of Holland, fell to the Burgundian Netherlands in the 15th century; Holland remained contentious territory throughout the European wars of religion and the eventual collapse of the Holy Roman Empire, when the length of the Rhine fell to the First French Empire and its client states. The Alsace on the left banks of the Upper Rhine was sold to Burgundy by Archduke Sigismund of Austria in 1469 and eventually fell to France in the Thirty Years' War. The numerous historic castles in Rhineland-Palatinate attest to the importance of the river as a commercial route.

paragraph_text: In many poor and developing countries much land and housing is held outside the formal or legal property ownership registration system. Much unregistered property is held in informal form through various associations and other arrangements. Reasons for extra-legal ownership include excessive bureaucratic red tape in buying property and building, In some countries it can take over 200 steps and up to 14 years to build on government land. Other causes of extra-legal property are failures to notarize transaction documents or having documents notarized but failing to have them recorded with the official agency.

paragraph_text: There are generally three possible arrangements by which a country can have a single border. The first is with a divided island such a Haiti and the Dominican Republic, or Ireland and the United Kingdom. The second is a peninsular relationship, where the first country borders the second and is otherwise surrounded by sea, while the second country borders other countries, as with Portugal and Spain, Denmark and Germany, or Canada and the United States. The third is the circumstance where the first country is a small country that is landlocked and completely surrounded by the second, larger country, as with The Vatican and Italy, or Lesotho and South Africa.
