a genus of plants belonging to the order pinaceæ (conifers) and to the family or section abietinæ. Five or six species are known; all from the Southern Hemisphere. The one so common in English gardens is A. imbricata, a native of the mountainous parts of southern Chile. Another species, A. excelsa, or Norfolk Island pine, is a splendid tree of giant size. All the genus are ornamental from their fine and unfading foliage.

in geometry, a portion of the circumference of a circle, cut off by two lines which meet or intersect it. Its magnitude is stated in degrees, minutes, and seconds, which are equal to those of the angle which it subtends. Hence, counted by degrees, minutes, and seconds, the arc of elevation and the angle of elevation of a heavenly body are the same, and the two terms may be used in most cases indifferently. The straight line uniting the two extremities of an arc is called its chord. Equal arcs must come from circles of equal magnitude, and each must contain the same number of degrees, minutes, and seconds as the others. Similar arcs must also each have the same number of degrees, minutes, and seconds, but they belong to circles of unequal magnitude. Concentric arcs are arcs having the same center. In mathematical geography, an arc of the earth's meridian, or a meridional arc, is an arc partly measured on the surface of the earth from N. to S., partly calculated by trigonometry. Such arcs have been measured in Lapland; in Peru; from Dunkirk, in France, to Barcelona, in Spain; at the Cape of Good Hope, and from Shanklin Down, in the Isle of Wight, to Balta, in Shetland. It was by these measurements that the earth was discovered to be an oblate spheroid. In electricity, a voltaic arc is a luminous are, which extends from one pencil of charcoal to another when these are

a pastoral romance in prose and verse by Sir Philip Sidney. Tragic images, shipwrecks, attacks by pirates, fights, and abductions, are interwoven with scenes of piping shepherds, gaily dressed ladies in daisy-studded fields, masquerading princes, and songs and dances innumerable. Sidney himself said of it, "It is a trifle, my young head must be delivered." See Sidney; Sir Philip Live ever, sweete booke; the simple image of his gentle witt, and the golden pillar of his noble courage; and ever notify unto the world that thy writer was the secretary of eloquence, the breath of the muses, the honeybee of the daintyest flowers of witt and arte, the pith of morall and intellectual virtues, the arme of Belonna in the field, the tongue of Suada in the chamber, the sprite of Practise in esse, and the paragon of excellency in print.--Harvey's Pierce's Supererogation. Sir Philip Sidney's Arcadia, the immortality of which was so fondly predicted by his admirers, and which, in truth, is full of noble thoughts, delicate images, and graceful turns of language, is now scarcely ever mentioned.--Irving, The Sketch Book. FROM THE ARCADIA. They are termed shepherds,--a happy people wanting little because they desire not much. Provision is the foundation of hospitality, and thrift the jewell of magnificence. His word was ever led by his thought and followed by his deed. Who only sees the ill is worse than blind.

the classical name of middle Peloponnesus, now forming the modern province of Arkadia, in the Morea, Greece. It occupies a high tableland having on the N., Achaia, E., Argolis, W., Elis, and, on the S., Laconia and Messenia. Area 1,600 square miles. It is intersected by mountain ranges, some of which are very lofty, and contains plains of some extent. Its principal river is the Roufia (Alpheus), the largest in the Morea. Lake Stymphalus, of classic mention, is found here. The inhabitants still retain their primitive mode of life as shepherds, pursuing a migratory existence. Chief towns, Tripolitza, Londari, Karitena, etc. Many interesting ruins are seen here, among them the remains of the cities of Phigaleia, Megalopolis, and Pallantium. Pop. about 175,000. From its first inhabitants, the Pelasgi, the land derived the name Pelasgia. In later times it was divided among the 50 sons of Lycaon into kingdoms, and received from Arcas the name Arcadia. In the course of time the small kingdoms made themselves free, and formed a confederacy. The principal were Mantinea, where Epaminondas obtained a victory and a tomb (now the village of Mondi), Tega (now Tripolitza), Orchomenus, Phenus, Psophis, and Megalopolis. Their chief deity was Pan; their chief business, the breeding of cattle and agriculture. This occasioned the pastoral poets to select Arcadia for the theater of their fables.
