The second group of settlers who came from the Caribbean islands were from Trinidad and Tobago; they were some 345 ex-Caribbean slaves, followed by some 620 ex-Caribbean slaves from Saint Vincent and the Grenadines. Another group of settlers, some 350 ex-Caribbean slaves, came from Saint Kitts and Nevis. The last two groups of settlers from the Caribbean islands were some 483 from Grenada and some 400 from Saint Lucia. As job opportunities and development growth increased, the ex-Caribbean slaves moved through Grand Cape Mount, Bomi County, Montserrado, Margibi County and other regions of Liberia to seek jobs and other opportunities. - Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km (11.7 million squaremiles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition. - Sir Richard Francis Burton (19 March 1821 20 October 1890) was an English explorer, geographer, translator, writer, soldier, orientalist, cartographer, ethnologist, spy, linguist, poet, fencer, and diplomat.

In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. - William Balfour Baikie (21 August 182430 November 1864) was a Scottish explorer, naturalist and philologist. - Aberdeen is Scotland's third most populous city, one of Scotland's 32 local government council areas and the United Kingdom's 37th most populous built-up area, with an official population estimate of 196,670 for the city of Aberdeen itself and 228,990 for the local authority area.

The country's economy centers on agriculture and fishing. Some of Mali's prominent natural resources include gold, being the third largest producer of gold in the African continent, and salt. About half the population lives below the international poverty line of $1.25 (U.S.) a day. A majority of the population (90%) are Muslims. - A country is a region that is identified as a distinct national entity in political geography. A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics. Regardless of the physical geography, in the modern internationally accepted legal definition as defined by the League of Nations in 1937 and reaffirmed by the United Nations in 1945, a resident of a country is subject to the independent exercise of legal jurisdiction. - Scotland (Scots: ) is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is otherwise surrounded by the Atlantic Ocean, with the North Sea to the east and the North Channel and Irish Sea to the south-west. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles and the Hebrides. - The Northern Isles is an archipelago comprising a chain of islands off the north coast of mainland Scotland. The climate is cool and temperate and much influenced by the surrounding seas. There are two main island groups: Shetland and Orkney. There are a total of 26 inhabited islands with landscapes of the fertile agricultural islands of Orkney contrasting with the more rugged Shetland islands to the north, where the economy is more dependent on fishing and the oil wealth of the surrounding seas. Both have a developing renewable energy industry. They also share a common Pictish and Norse history. Both island groups were absorbed into the Kingdom of Scotland in the 15th century and remained part of the country following the formation of the Kingdom of Great Britain in 1707, and later the United Kingdom after 1801. The islands played a significant naval role during the world wars of the 20th century. - The British Leeward Islands now refers to the Leeward Islands as an English and later British colony from 1671 to 1958, except for the years from 1816 to 1833.

About 92% of the province's population lives on the island of Newfoundland (and its neighbouring smaller islands), of whom more than half live on the Avalon Peninsula. The province is Canada's most linguistically homogeneous, with 97.6% of residents reporting English (Newfoundland English) as their mother tongue in the 2006 census. Historically, Newfoundland was also home to unique varieties of French and Irish, as well as the extinct Beothuk language. In Labrador, local dialects of Innu-aimun and Inuktitut are also spoken. - West Africa, also called Western Africa and the West of Africa, is the westernmost subregion of Africa.

It is generally regarded as the longest river in the world, however other conflicting sources cite a 2007 study that gave the title to the Amazon River in South America. The Nile, which is 6,853km (4,258miles) long, is an "international" river as its water resources are shared by eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Congo-Kinshasa, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan. - The Hebrides (Scottish Gaelic: "Innse Gall"; Old Norse: "Sureyjar") comprise a widespread and diverse archipelago off the west coast of mainland Scotland. There are two main groups: the Inner and Outer Hebrides. These islands have a long history of occupation dating back to the Mesolithic, and the culture of the residents has been affected by the successive influences of Celtic, Norse, and English-speaking peoples. This diversity is reflected in the names given to the islands, which are derived from the languages that have been spoken there in historic and perhaps prehistoric times. - Taqali (also spelled Tegali) was a state in the Nuba Hills, in modern-day central Sudan. Unlike the surrounding Kordofan, the uplands of the hills were quite moist and suitable to agriculture and a dense population. The state was centred upon the Taqali Massif the highest part of the hills in the northeast of the region. It early history is unclear. Oral traditions state it was founded many centuries ago at the same time as the Kingdom of Sennar came into being. Some scholars doubts these tales and believes that the state did not come into being until the late eighteenth century (between 1750 and 1780), and that the early rulers on the king list are semi-mythological. - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union.
