Barbed wire is usually shipped to customers on wooden spools, each holding approximately 100 lb or 80 to 100 rods. A hole is provided through the centre of the spool for inserting a bar, on which the reel can revolve for unwinding the wire as it is put up. After the wire is stretched in place, it is attached to the wooden posts by means of galvanized steel wire staples, ordinarily made from No. 9 wire. They are cut with a sharp, long, diagonal point and can be easily driven into the posts. On account of the rapid decay and destruction of wooden posts, steel posts have become popular, as also have reinforced concrete posts, which add materially to the durability of the fence. It is essential that barbed wire should be stretched with great care. For this purpose a suitable barbed wire stretcher is necessary.

Barbed wire fencing is now manufactured in various patterns. The general process may be outlined briefly as follows:—The wire is made of soft Bessemer or Siemens-Martin steel, and is drawn in the wire mill in the usual way. Galvanizing is done by a continuous process. The coil of wire to be galvanized is placed on a reel. The first end of the wire is led longitudinally through an annealing medium—either red-hot lead or heated fire-brick tubes—of sufficient length to soften the wire. From the annealing furnace, the wire is fed longitudinally through a bath of muriatic acid, which removes the scale, and from the acid, after a thorough washing in water, the wire passes through a bath of spelter, heated slightly above the melting point. After coming from the spelter and being cooled by water, the wire is wound on suitable take-up blocks into finished coils. From 30 to 60 wires are passing simultaneously in parallel lines through this continuous galvanizing apparatus, thus insuring a large output. The galvanizing gives the wire a bright finish and serves to protect it from the corrosive action of the atmosphere. There is a considerable demand for painted fencing, in the manufacture of which the galvanizing is dispensed with, and the spools of finished barbed wire, as they come from the barbing machine, are submerged in paint and dried. The barbing and twisting together of the two longitudinal strand wires is done by automatic machinery. A brief description of the manufacture of 2 and 4 point Glidden wire is as follows:—Two coils of wire on reels are placed behind the machine, designed to form the main or strand wires of the fence. One of the main wires passes through the machine longitudinally. One or two coils of wire are placed on reels at either side of the machine for making 2 or 4 point wire respectively. These wires are fed into the machine at right angles to the strand wire. At each movement of the feeding mechanism, when fabricating 2 point wire, one cross wire is fed forward. A diagonal cut forms a sharp point on the first end. The wire is again fed forward and instantly wrapped firmly around one strand wire and cut off so as to leave a sharp point on the incoming wire as before, while the bit of pointed wire cut off remains as a double-pointed steel barb attached firmly to the strand wire. This wire armed with barbs at regular intervals passes on through a guide, where it is met by a second strand wire—a plain wire without barbs. The duplex strand wires are attached to a take-up reel, which is caused to revolve and take up the finished barbed wire simultaneously and in unison with the barbing machine. In this way the strand wires are loosely twisted into a 2-ply strand, armed with barbs projecting at right angles in every direction.

When once started, the operation of barbed wire making is continuous and rapid. The advantage of two strands is the automatic adjustment to changes of temperature. When heat expands the strands, the twist simply loosens without causing a sag, and when cold contracts them, the twist tightens, all without materially altering the relative lengths of the combined wires. A barbed wire machine produces from 2000 to 3000 lb of wire per day of ten hours.

In some American states, the use of barbed wire is regulated by law, but as a rule these laws apply to placing barbed wire on highways. Others prohibit the use of barbed wire fencing to indicate the property line between different owners, unless both agree to its use. In some states the use of barbed wire is prohibited unless it has a top rail of lumber.

Barbed wire is also employed in connexion with "obstacles" in field fortifications, especially in what are known as "high wire entanglements." Pointed stakes or "pickets," 4 ft. high, are planted in rows and secured by ordinary wire to holdfasts or pegs in the ground. Each picket is connected to all around it, top and bottom, by lengths of barbed wire.

In England, where the use of barbed wire has also become common, the Barbed Wire Act 1893 enacted that, where there is on any land adjoining a highway within the county or district of a local authority, a fence which is made with barbed wire (i.e. any wire with spikes or jagged projections), or in which barbed wire has been placed, and where such barbed wire may probably be injurious to persons or animals lawfully using the highway, the local authority may require the occupier of the land to abate the nuisance by serving notice in writing upon him. If the occupier fails to do so within the specified time, the local authority may apply to a court of summary jurisdiction, and such court, if satisfied that the barbed wire is a nuisance, may by summary order direct the occupier to abate it, and on his failure to comply with the order within a reasonable time, the local authority may execute it and recover in a summary manner from the occupier the expenses incurred.

BARBEL (Barbus vulgaris), a fish of the Cyprinid family, which is an inhabitant of the rivers of central Europe, and is very locally distributed in England. It has four barbels (Lat. barba, beard; fleshy appendages hanging from the mouth), and the first ray of the short dorsal fin is strong, spine-like and serrated behind. It attains a weight of 50 lb on the continent of Europe. The genus of which it is the type is a very large one, comprising about 300 species from Europe, Asia and Africa, among which is the mahseer or mahaseer, the great sporting fish of India.

BARBÉ-MARBOIS, FRANÇOIS, Marquis de (1745-1837), French politician, was born at Metz. He began his public career as intendant of San Domingo under the old régime. At the close of 1789 he returned to France, and then placed his services at the disposal of the revolutionary government. In 1791 he was sent to Regensburg to help de Noailles, the French ambassador, in the negotiations with the diet of the Empire concerning the

possessions of German princes in Alsace and Lorraine. Suspected of treason, he was arrested on his return but set at liberty again. In 1795 he was elected to the Council of the Ancients, where the general moderation of his attitude, especially in his opposition to the exclusion of nobles and the relations of émigrés from public life, brought him under suspicion of being a royalist, though he pronounced a eulogy on Bonaparte for his success in Italy. At the coup d'état of the 18th Fructidor (September 4) 1797, he was arrested and transported to French Guiana. Transferred to Oléron in 1799, he owed his liberty to Napoleon, after the 18th Brumaire. In 1801 he became councillor of state and director of the public treasury, and in 1802 a senator. In 1803 he negotiated the treaty by which Louisiana was ceded to the United States, and was rewarded by the First Consul with a gift of 152,000 francs. In 1805 he was made grand officer of the legion of honour and a count, and in 1808 he became president of the cour des comptes. In return for these favours, he addressed Napoleon with servile compliments; yet in 1814 he helped to draw up the act of abdication of the emperor, and declared to the cour des comptes, with reference to the invasion of France by the allies, "united for the most beautiful of causes, it is long since we have been so free as we now are in the presence of the foreigner in arms." In June 1814, Louis XVIII. named him peer of France and confirmed him in his office as president of the cour des comptes. Deprived of his positions by Napoleon during the Hundred Days he was appointed minister of justice in the ministry of the duc de Richelieu (August 1815). In this office he tried unsuccessfully to gain the confidence of the ultra-royalists, and withdrew at the end of nine months (May 10, 1816).
