142 A N T A N T antonomasia; as, a " Cicero" for an orator. In both cases the figure is akin to metonymy. ANTRIM, a maritime county in the north-east corner of Ireland, in the province of Ulster, situated between 54 26 and 55 12 16* N. lat., and 5 47 and 6 52 W. long. It comprises, without including the 50,803 acres under water, an area of 711,275 statute acres, of which 1 6,702 belong to the incorporated county of the town of Carrickfergus. There were, in 1871, 257,211 acres under tillage, 373,839 in pasture, 6717 in plantation, and 72,065 waste. The county presents a considerable line of coast to the Atlantic Ocean on the north, and to the Irish Channel on the east ; while Belfast Lough and the river Lagan divide it from the county of Down on the south ; and Lough Neagh and Lough Beg, together with the river Bann, form its boundaries on the west, except towards the mouth of the river, where a small portion of the county of Londonderry lies on the eastern bank. In area Antrim is exceeded by eight other counties in Ire land, but in population by Cork and Dublin alone. A large proportion of the surface, especially towards the east, con sists of mountains and bogs ; and it is computed that about 1 20,000 acres are irreclaimable. The mountains, occupying about one-third of the county, stretch from south to north, and terminate on the northern shore in abrupt and almost perpendicular declivities. Among the principal heights may be mentioned Trostan, 1810 feet; Knocklayd, 1685; Divis, 1567; Agnew s Hill, 1558; and Slemish, 1457. They attain their greatest elevation neat the coast, and have a gradual descent inland, so that many of the streams, with their sources near the sea, flow south and west into Lough Neagh. The mountainous region has a gentler in clination as it approaches the Bann, and is occupied by turf- bogs susceptible of improvement. Some of the valleys, especially that of the Lagan, extend to a considerable width, and are of great fertility. The most extensive level tracts of rich and well-cultivated laud lie along the shores of Lough Neagh, and from Belfast to Carrickfergus, and thence to Larne, between the mountain range and the sea. The most remarkable cliffs are those of perpendicular basaltic columns, which extend for many miles along the northern shore, and are most strikingly displayed in Fair Head and the Giant s Causeway. Lough Neagh, the largest .lake in Europe, with the excep tion of Lake Ladoga, Lake Wener, and the Lake of Geneva, is principally in Antrim. It is about 20 miles in length, 12 in breadth, and 80 in circumference, with an area of 98,255^ statute acres, of which 50,025 belong to Antrim ; its greatest depth is from 45 to 48 feet, and its surface is 48 feet above the level of the sea. The lower Bann, obstructed by weirs and rocks, being the only outlet for the waters of the lake, which is fed by the Maine, the Six-mile Water, and a number of smaller streams, the surrounding country is in winter liable to be damaged by floods. The waters of the Lough, or at least of the Crunilin, one of the streams flowing into it, have petrifying powers ; and some of the petrifactions are very beautiful, take a good polish, and rival those of Antigua. North of Lough Neagh, and connected with it by the river Bann, is Lough Beg, or the " small lake," containing 3145 acres, partly in Antrim. It is generally 15 feet lower than the larger lake, which it excels in the diversified and pleasing scenery of its banks. The Bann and Lagan, both of which rise irr the county of Down, are the only rivers of importance. Of those strictly belonging to Antrim, none are navigable. They are generally rapid streams, of great value for turning machinery. The chief indentations of the coast are Red Bay, Carnlough, Glenarm, and Lough Larne. About 7 miles from the north coast, opposite Ballycastle, surrounded by a wild and troubled sea, lies the island of Rath! in, 6| miles in length and 1| in breadth, of similar basaltic and limestone formation with the neighbouring mainland. About a fourth of its 3399 acres are arable, and it supports a population of 453. There is a lighthouse on it with a fixed light. The climate of Antrim is very temperate. The average annual rain-fall at Belfast is about 33 inches. The geology of Antrim is of considerable interest, both on account of its peculiar character, and because the arrange ment and alternations of strata are laid bare with more than usual distinctness. In all its more important features it coincides with the adjoining county of Londonderry. The greater portion of the surface is covered with trap. Along the coast, from a little way to the north of Carrickfergus, and up the valley of the Lagan, there is a considerable line of New Red Sandstone. All along from the south of Lisburn to Red Bay there is a chalk formation coming to the surface in narrow lines. It is quarried in many places, and varies in thickness from a few feet to 170, as at Glenarm. The south side of Red Bay and a part of the north are formed of New Red Sandstone, which gives place to porphyry near Cushendall, and is succeeded by Devonian grit northwards. There is a considerable circle of porphyry about five or six miles north-east of the town of Antrim. The lias (except at Larne) is very insignificant, and the greensaud still more so. The coal measures are remarkable for their association with the basaltic formation, and differ from all the other coal districts in Ireland in wanting the underlying limestone, and resting directly on mica slate. The workings at the Ballycastle collieries are probably the oldest in the kingdom. In 1770 the miners accidentally discovered a complete gallery, which had been driven many hundred yards into the bed of coal, branching into thirty-six chambers dressed quite square, and in a workman-like manner. No tradition of the mine having been formerly worked remained in tho neighbourhood. The coal of some of the beds is bituminous, and of others anthracite. The quantity available was calculated by the commissioners in 1871 to be 16,000,000 tons, at depths not exceeding 4000 feet. Lignite occurs in great abundance round about Lough Neagh, as at Ballintoy, Limincogh, Killymorris. In most places it is covered with columns of basalt; and in spite of the compressed state in which it is found, the bark and knots are often quite distinct, and the rings of growth may be counted. Basaltic pillars are found in many places besides the famous Giant s Causeway, as round about Coleraine, near Dunluce, at Ballintoy, Ballycastle, Ballygally Head (near Larne), in tho neighbourhood of Carrickfergus, at Shane s Castle, and the mouth of the Glenavy. Iron ore is obtained at Ardshins, Belfast, Ballycastle, Glenrava, Kilwaughter, and Shane s Castle the produce in 1871 being 157,874 tons, of tho value of 61,110. Among the other minerals to be met with in Antrim, chalcedony (at Lough Neagh, and known as Lough Neagh pebbles), chrysolite, dolomite, jasper, onyx, opal, and talc may be mentioned. Very fine rock-salt is got at Duncrue, two miles north-west of Carrickfergus, and at one or two places in the same "district. The Belfast Salt Mining Company raised during 1871 18,260 tons, and in 1870, 19,450. The mineral (chalybeate) waters of the county are in the neighbourhood of Antrim, Bally castle, Belfast, Carrickfergus, and Larne. The chief bathing-places are Ballycastle, Cushendall, Cush- endun, Glenarm, Port Ballintrae, and Portrush. They are exposed to the easterly winds prevalent in spring, but are de sirable summer residences. There is much variety of scenery in the county, from the low and somewhat monotonous shores of Lough Neagh, and the dreary bog and mountain land of the interior, to the wild romantic scenery of the northern coast, and the fantastically beautiful shores about Glenarm.

The soil varies greatly according to the district, being
