JOIGNY, a town of central France, capital of an arrondissement in the department of Yonne, 18 m. N.N.W. of Auxerre by the Paris-Lyon-Méditerranée railway. Pop. (1906), 4888. It is situated on the flank of the hill known as the Côte St Jacques on the right bank of the Yonne. Its streets are steep and narrow, and old houses with carved wooden façades are numerous. The church of St Jean (16th century), which once stood within the enceinte of the old castle, contains a representation (15th century) of the Holy Sepulchre in white marble. Other interesting buildings are the church of St André (12th, 16th and 17th centuries), of which the best feature is the Renaissance portal with its fine bas-reliefs; and the church of St Thibault (16th century), in which the stone crown suspended from the choir vaulting is chiefly noticeable. The Porte du Bois, a gateway with two massive flanking towers, is a relic of the 10th century castle; there is also a castle of the 16th and 17th centuries, in part demolished. The hôtel de ville (18th century) shelters the library; the law-court contains the sepulchral chapel of the Ferrands (16th century). The town is the seat of a sub-prefect and has tribunals of first instance and of commerce, and a communal college for boys. It is industrially unimportant, but the wine of the Côte St Jacques is much esteemed.

Joigny (Joviniacum) was probably of Roman origin. In the 10th century it became the seat of a countship dependent on that of Champagne, which after passing through several hands came in the 18th century into the possession of the family of Villeroi. A fragment of a ladder preserved in the church of St André commemorates the successful resistance offered by the town to the English in 1429.

JOINDER, in English law, a term used in several connexions.

Joinder of causes of action is the uniting in the same action several causes of action. Save in actions for the recovery of land and in actions by a trustee in bankruptcy a plaintiff may without leave join in one action, not several actions, but several “causes of action.” Claims by or against husband and wife may be joined with claims by or against either of them separately. Claims by or against an executor or administrator as such may be joined with claims by or against him personally, provided such claims are alleged to arise with reference to the estate of which the plaintiff or defendant sues or is sued as executor or administrator. Claims by plaintiffs jointly may be joined with claims by them or any of them separately against the same defendant.

Joinder in pleading is the joining by the parties on the point of matter issuing out of the allegations and pleas of the plaintiff and the defendant in a cause and the putting the cause upon trial.

Joinder of parties.—Where parties may jointly, severally or in the alternative bring separate actions in respect of or arising out of the same transaction or series of transactions they may, by Order XVI. of the rules of the supreme court, be joined in one action as plaintiffs.

JOINERY, one of the useful arts which contribute to the comfort and convenience of man. As the arts of joinery and carpentry are often followed by the same individual, it appears natural to conclude that the same principles are common to both, but a closer examination leads to a different conclusion. The art of carpentry is directed almost wholly to the support of weight or pressure, and therefore its principles must be sought in the mechanical sciences. In a building it includes all the rough timber work necessary for support, division or connexion, and its proper object is to give firmness and stability. The art of joinery has for its object the addition in a building of all the fixed woodwork necessary for convenience or ornament. The joiner’s works are in many cases of a complicated nature, and often require to be executed in an expensive material, therefore joinery requires much skill in that part of geometrical science which treats of the projection and description of lines, surfaces and solids, as well as an intimate knowledge of the structure and nature of wood. A man may be a good carpenter without being a joiner at all, but he cannot be a joiner without being competent, at least, to supervise all the operations required in carpentry. The rough labour of the carpenter renders him in some degree unfit to produce that accurate and neat workmanship which is expected from a modern joiner, but it is no less true that the habit of neatness and the great precision of the joiner make him a much slower workman than the man practised in works of carpentry. In carpentry framing owes its strength mainly to the form and position of its parts, but in joinery the strength of a frame depends to a larger extent upon the strength of the joinings. The importance of fitting the joints together as accurately as possible is therefore obvious. It is very desirable that a joiner shall be a quick workman, but it is still more so that he shall be a good one, and that he should join his materials with firmness and accuracy. It is also of the greatest importance that the work when thus put together shall be constructed of such sound and dry materials, and on such principles, that the whole shall bear the various changes of temperature and of moisture and dryness, so that the least possible shrinkage or swelling shall take place; but provision must be made so that, if swelling or shrinking does occur, no damage shall be done to the work.
