LAWN, finely woven white goods, cotton or linen, of an open texture, plain or printed. The white 'sleeves, which form a part of the dress of a bishop in the English Church, are made of 'lawn.
a modern game, played on grass, gravel, cinder or asphalt courts, with balls and rackets. The face of the racket is now invariably plane, and consists of a net formed of tightly-strung gut. The balls are of rubber covered with white flannel, about two and one-half inches in diameter and two ounces in weight. For a game between two players.(a single-thanded game) the court is 78 feet long by 27 wide. It is drvided across the middle by a net, the ends of which are attached to two posts, which stand three feet outside the court on each side. The height 'of the .net is three and one half feet at the posts and three feet at the centre. At each end of the court, parallel to the net and 39' feet from it, are drawn the base lines, the extremities of which are connected by the sidelines. Half-way between the side-lines, and parallel to them, is drawn the half-court line, dividing .the space on either side of the net into twb equal parts called the right and left courts. On either side of the net, at a dis tance of 21 feet from it, and parallel to it, are drawn the service-lines. The players .take up their positions on opposite sides of the net and one of them, decided by tossing, called the server, standing with one foot behind and one foot on the baseline, -serves the ball from his right court into the diagonally opposite court. The ball is served by being struck with the face of the racket while it is in the air, and the stroke is counted a fault if the service be from the wrong court, or if the server do not stand as directed, or if the ball do not strike the ground in the diagonally opposite court within the service-line. After a fault the server must serve again from the same court, unless the stroke was a fault because served from the wrong court. The next.service comes from the left court, and thereafter the courts are taken alternately. The non-server is called the striker out, and it is his business to return the ball by striking it with the face of his racket. The server wins a stroke if the striker-out °volley the service," that is, strike the ball before it touches the ground, or fail to return the service i or the ball in-play, or return the service or the ball in-play so that it drop outside any of the lines which bound his opponent's court, or otherwise lose a stroke in accordance with the recognized aws of the game. The striker-out
wins a stroke if the server serve two consecu tive faults, or fail to return the ball in-play, or return the ball in-play so that it drop outside any of the lines which bound his opponent's court, or otherwise lose a stroke. On either player winning his first stroke the score is called 15 for that player; on either player win ning his second stroke the score is called 30 for him; on either winning his third stroke his score is called 40, and the fourth stroke won by either player is scored game for that player. However, if both players have won three strokes,•the score is called
and the next stroke won by either player is scored advantage for that player. If the same player win the fol lowing stroke,•he wins the game; but if he lose the next stroke, the score is again called deuce, and so on until one player win two strokes immediately following the score at deuce. The player who first wins six games wins a set, but with both at five a method of scoring similar to advantage is often introduced. Sides are change•at the end of every set. Three-handed and four-ihanded lawn-tennis differ in no essen tials from the game as above described. The game of lawn-tennis as now known was intro duced about 1875. • Bibliography.— Dewhurst, E. B.,
