developed into the foremost warrior of his time, and it was from his prowess at the siege of Corioli, when he took the town single-handed, that he received his cognomen. But his hatred of the plebs losfe him the consulship, and when he ventured to advise that the people, who were suffering from a dearth of corn, should not be relieved from the supplies obtained from Sicily unless they would consent to the abolition of their tribunes, he was condemned to banishment. Obtaining the command of the Volscian army, he advanced against his native city. In vain the first men of Rome prayed for moderate terms. He would agree to nothing less than the restoration to the Volscians of all their land, and their admission among the Roman citizens. At last his mother, his wife, Volumnia, and his children, accompanied by a company of Roman matrons of the highest birth, came to the Volscian camp, and by their tears and entreaties prevailed. He led back the Volscian army, and, according to one account, paid with his life the penalty of his tenderness. Niebuhr has shown that several
important parts of the legend are probably historical.CORIOLI, an ancient Latin city, celebrated as giving a surname to C. Marcius Coriolanus. It is first mentioned in Roman story as falling into the hands of the Volsci, and bsing retaken from them by the Romans, 493 B.C. It was never a large or important place, and seems to have dropped out of existence before the close of the 5th century B.C. The site of Corioli is now unknown. Nibbey and Gell have quite conjecturally assigned it to the hill called Monte (Hove, about nineteen miles from Rome on the way to Antium, while others, with as little ground, have suggested a hill four miles nearer Antium.
CORK (perhaps from cortex, bark) is the outer layer of the bark of an evergreen species of oak (Quercus Suber). The tree reaches the height of about 30 feet, growing in the south of Europe and on the North African coasts generally ; but it is principally cultivated in Spain and Portugal. The outer layer of bark in the cork oak by annual additions from within gradually becomes a thick soft homogeneous mass, possessing those compressible and elastic properties upon which the economic value of the material chiefly depends. The first stripping of cork from young trees takes place when they are from fifteen to twenty years of age. The yield, which is rough, unequal, and woody in texture is called virgin cork, and is useful only as a tanning substance, or for forming rustic work ia ferneries, conservatories, &c. Subsequently the bark is removed every eight or ten years, the quality of the cork improving with each successive stripping ; and the "trees continue to live and thrive under the operation for 150 years and upwards. The produce of the second barking is still so coarse in texture that it is only fit for making floats for nets and for similar applications. The operation of strip ping the trees takes place during the months of July and August. Two cuts are made round the stem, one a little above the ground, and the other immediately under the spring of the main branches. Between these three or four longitudinal incisions are then made, the utmost care being taken not to injure the inner bark. The cork is thereafter removed in the sections into which it has been cut, by inserting under it the wedge-shaped handle of the implement used in making the incisions. After the outer surface has been scraped and cleaned, the pieces are flattened by heating them over a fire and submitting them to pressure on a flat surface. In the heating operation the surface is charred, and thereby the pores are closed up, and what is termed " nerve " is given to the material. In this state the cork is ready for manufacture or exportation.
Cork possesses a combination of properties which peculiarly fits it for many and diverse uses, for some of which it alone is found applicable. The leading purpose for which it is used is for forming bungs and stoppers for bottles and other vessels containing liquids. Its com pressibility, elasticity, and practical imperviousness to both air and water so fit it for this purpose that the term cork is even more applied to the function than to the substance. Its specific lightness, combined with strength and durability, recommend it above all other substances for forming life buoys, belts, and jackets, and in the construction of life boats and other apparatus for saving from drowning. On account of its lightness, softness, and non-conducting pro perties it is used for hat-linings and the soles of shoes, the latter being a very ancient application of cork. It is also used in making arti6cial limbs, for lining entomological cases, for pommels in leather-dressing, and as a medium for making architectural models. Chips and cuttings are ground up and mixed with india-rubber to form kamptulicon floor-cloth, a preparation now, however, almost superseded by linoleum, which consists chiefly of a mixture of boiled linseed oil and ground cork applied over a canvas backing. The inner bark of the cork-tree is a valuable tanning material.
Certain of the properties and uses of cork were known to the ancient Greeks and Romans, and the latter, we find by Horace (Odes, iii. 8), used it as a stopper for wine- vessels:—

It appears, however, that cork was not generally used for stopping bottles till so recent a period as near the end of the 17th century, and bottles themselves were not employed for storing liquids till the 15th century. Many substitutes have been proposed for cork as a stoppering agent ; but except in the case of aerated liquids none of these has recommended itself in practice. For aerated water bottles several successful devices have recently been introduced. The most simple of these is an Indian-rubber ball pressed upwards into the narrow of the bottle neck by the force of the gas contained in the water ; and in another system a glass ball is similarly pressed against an Indian -rubber collar inserted in the neck of the bottle.
The cutting of corks by machinery has been found to be a matter of much difficulty, owing to the liability of the cutting edges becoming blunt, and the necessity of keeping them very sharp. Many machines have bsen proposed, but the work is still almost entirely done by hand labour. Messrs Crawhall & Campbell of Glasgow have recently introduced a machine which appears to be at once simple, expeditious, and efficient. The apparatus cuts corks and bungs of any diameter up to 3
CORK, a maritime county in the south-west of Ireland, province of Munster, bounded on the S. by the Atlantic, E. by Waterford and Tipperary, N. by Limerick, and W. by Kerry. It is the largest county in Ireland, and contains an area of 1,849,686 acres, or 2890 square miles. The outline of the county is irregular; its sea margin is for the most part bold and rocky, and is intersected by the Bays of Bantry, Dunmanus, and Roaring Water. The southern part of the coast projects several headlands into the ocean, and its south-eastern side is indented by Cork Harbour, and Ballycotton and Youghal Bays.
low rounded ridges, with corresponding valleys, running east and west, except in the western portion of the count) , which is more mountainous. Those valleys are drained by the Blackwater, the Lee, and the Bandon River. The most elevated part of the county is in connection with the Boghra Mountains, the highest of which, Cahorbanaghor,
reaches 2239 feet. North of the Blackwater the county is
