Information:  - The British Antarctic Expedition 190709, otherwise known as the Nimrod Expedition, was the first of three expeditions to the Antarctic led by Ernest Shackleton. Its main target, among a range of geographical and scientific objectives, was to be first to the South Pole. This was not attained, but the expedition's southern march reached a Farthest South latitude of 88° 23' S, just from the pole. This was by far the longest southern polar journey to that date and a record convergence on either Pole. A separate group led by Welsh Australian geology professor Edgeworth David reached the estimated location of the South Magnetic Pole, and the expedition also achieved the first ascent of Mount Erebus, Antarctica's second highest volcano.  - Dumfries (; possibly from ) is a market town and former royal burgh within the Dumfries and Galloway council area of Scotland. It is near the mouth of the River Nith into the Solway Firth. Dumfries was a civil parish and became the county town of the former county of Dumfriesshire. Dumfries is nicknamed "Queen of the South". People from Dumfries are known colloquially as "Doonhamers".  - The Solway Firth is a firth that forms part of the border between England and Scotland, between Cumbria (including the Solway Plain) and Dumfries and Galloway. It stretches from St Bees Head, just south of Whitehaven in Cumbria, to the Mull of Galloway, on the western end of Dumfries and Galloway. The Isle of Man is also very near to the firth. The firth comprises part of the Irish Sea.  - Arrol - Aster was a British car maker founded in 1927 when Arrol - Johnston and Aster merged . The Wembley , London works of Aster was closed and production concentrated at the Heathhall , Dumfries factory of Arrol - Johnston . At first , manufacture of all the cars previously made by the two companies was continued along with those made under the Galloway badge but in 1928 a rationalisation was carried out . The cars were complex and expensive and sales were poor resulting in the company going into receivership in 1929 and finally closing in 1931 . The company was responsible for making the body for Sir Malcolm Campbell 's Blue Bird car in 1929 and an Arrol - Aster car was entered in the 1931 24 Hours of Le Mans .  - Arrol-Johnston (later known as Arrol-Aster) was an early Scottish manufacturer of automobiles, which operated from 1896 to 1931 and produced the first automobile manufactured in Britain. The company also developed the world's first "off-road" vehicle for the Egyptian government, and another designed to travel on ice and snow for Ernest Shackleton's Nimrod Expedition to the South Pole.  - A royal burgh was a type of Scottish burgh which had been founded by, or subsequently granted, a royal charter. Although abolished in law in 1975, the term is still used by many former royal burghs.  - Dumfriesshire or the County of Dumfries ("Siorrachd Dhùn Phris" in Gaelic) is lieutenancy area and historic county of Scotland.  - The River Nith is a river in South West Scotland.  - Dumfries and Galloway is one of 32 unitary council areas of Scotland and is located in the western Southern Uplands. It comprises the historic counties of Dumfriesshire, Stewartry of Kirkcudbright and Wigtownshire, the latter two of which are collectively known as Galloway. The administrative centre is the town of Dumfries.  - Market town or market right is a legal term, originating in the Middle Ages, for a European settlement that has the right to host markets, distinguishing it from a village and city. A town may be correctly described as a "market town" or as having "market rights", even if it no longer holds a market, provided the legal right to do so still exists.  - A County town is usually the location of administrative or judicial functions within the county, or it has been established over time as the "de facto" main town of a county. The concept of a county town eventually became detached from its original meaning of where the county administration or county hall is based. In fact, many county towns are no longer part of the administrative county. For example, Nottingham is administered by a unitary authority entirely separate from the rest of Nottinghamshire. Many county towns are classified as cities, but all are referred to as county towns regardless of whether city status is held or not.
