trike it more than once; but should the ball
then fail to land in the opponents' court, the server loses his
second serve.

In serving, the ball must be batted at least ten feet by the server
before being touched by any other player on his side.

No "dribbling" is allowed in serving.

A successful server continues serving until his side allows the ball
to touch the floor, knocks it out of bounds, or fails to return it to
the opponents. A server may also lose as follows:

If a returned ball hits a player on the server's side and bounces into
the opponents' court, it is considered in play. If it hits such a
player and does not bounce into the opponents' court, the server is
out, losing his second trial.

If the ball hits the net during service, it is counted a dead ball and
loses the server one of his trials.

If a served ball falls outside the opponents' court, the server loses
his turn.

The players on a side take turns in serving.

RULES OF PLAY.--The ball must always be batted with the open palm. The
ball should be returned by the opponents before it can strike the
ground. Any number of players may strike the ball to send it across
the net, but no player may strike more than twice in succession.
Having struck the ball twice, a player may resume his play only after
some other player has struck it. The ball is thus volleyed back and
forth across the net until one side fails to return it or allows it to
touch the floor, or until it goes out of bounds. A ball is put out of
play by hitting the net in returning after a serve. A ball which
bounds back into the court after striking any other object except the
floor or ceiling is still in play. It is permissible to strike the
ball with both hands at once (open palms).

If a player touches the net at any time, the ball is thereby put out
of play. Should this player be on the serving side, his side loses the
ball and it goes to the opponents. Should this player be on the
receiving side, the serving side scores one point. Should the net be
touched simultaneously by opponents, the ball is thereby put out of
play and the serving side serves again.

No dribbling is allowed at any time through the game; _i.e._ no
keeping the ball in the air by one player hitting it quickly and
repeatedly.

In sending the ball across the net, players should aim for an
unprotected part of the opponents' court, or try in other ways to
place them at a disadvantage.
