the basemen and guards of each team
shall exchange places, basemen becoming guards, and _vice versa_. For
match games a club shall be represented by a picked team.

OFFICERS.--The game shall be in charge of a referee who shall call
score and fouls and put the ball in play at the beginning of each
half, and after each foul.

The referee may be assisted by an umpire and inspectors, if desired;
but for other than match games this is not necessary.

OBJECT OF THE GAME.--The main object of the game is for the basemen of
a team to pass the ball from one to another, each pass successfully
made scoring for the team, as described under "Score."

The object of the guards is to intercept the passage of the ball and
send it back to their own basemen for similar play.

RULES.--The game shall be played in two halves of 15 minutes each,
with a 5-minute rest between, except at final meets, where halves may
be shortened to 6 minutes, if desired.

Guards may move around freely on their own half of the ground, but
each should be responsible for guarding one particular baseman. Guards
may not step within bases.

Guards may not enter the neutral strip except when called there in
rotation, as explained under "Start" to put the ball in play.

The play of the ball need not be in consecutive order from base to
base, but may zigzag across the circle. It does not score when caught
a second time by the same baseman during a given play, such a catch
ending the possible score for that team for that round of the ball;
and it cannot score after being caught by the captain, though his
catch scores.

START.--The ball shall be put in play by the referee, who shall toss
it up in the center of the neutral strip between two guards, one from
each team, who shall try to secure it. To touch the ball shall not
give the guard possession of it; it shall be held in both hands. In
case of dispute, the referee shall again toss the ball.

Guards shall be called in regular succession to the neutral strip to
put the ball in play. The two called shall be from similar positions
on opposite sides of the field.

The ball is put in play from the center at the opening of the halves,
and after a foul, but not after a score made in regular play; in other
words, the ball continues in play until a foul is called or the half
ends.

SCORE.--One point shall be scored for a team whenever one of its
basemen catches a ball thrown by any other of its basemen except the
