COURT TENNIS. Indoor tennis (see dia gram). Usually the court occupies an entire building, and is lighted from the roof, occupying R. playing space of 96 by 32 feet, surrounded on three sides by a corridor about 0 feet wide (the penthouse), which has a sloping roof about 7 feet high. The spectators occupy the dedens, or the part of the penthouse situated in the rear of the court, and separated from the same by an open grating. The most complete courts; have floors of asphalt, and cement walls painted black to a height of 18 feet. The nets divide the court, and also the service and ba:.-ard sides of the game. The tambour is a projection on the hazard side, resembling a chimney, and near it (in the penthouse) is the grille. The chases are num henel on the wall (from I to 0) and are em ployed to divide part of the court into the mini her of spaces required by the game. In playing the game the server must stand in the service court and serve the ball over the penthouse, it being required to strike on the penthouse roof and then roll off into the receiving court. The player on the hazard side strikes it on the bound wherever he chooses, if only it first strikes the ground on the opposite side of the net: for in stance, he may strike it against the nearest wall, so that it rebounds across the net. A 'chase' is
called when the player fails to strike the ball before the second bound—unless he is on the hazard side and beyond the service-line. Fur ther, a record is made of the cross-lines at which the ball bounds; which, however, does not affect the score nnloss the game stands at 40, in which event sides are changed and the contestants play for the 'chase.' The player responsible for the `chase,' by permitting the same to be made, will attempt to return the ball nearer to the end wall than the point at which it was marked, to insure its bounding a second time, making the attempt as often as his opponent returns the ball until he either succeeds or misses. In the former event he is credited with the `strike;' while in the latter, his opponent scores. For more de tailed information regarding the game, its scor ing and its history, see TENNIS.
