by the first person touching it. In case of dispute the umpire shall throw it straight into the field. The thrower in is allowed five seconds, if he holds it longer, it shall go to the opponent. If any side persists in delaying the game, the umpire shall call a foul on them. The umpire shall be the judge of the men and shall note the fouls, and notify the referee when three consecutive fouls have been made. He shall have power to disqualify people according to Rule 5. The referee shall be judge of the ball and shall decide when the ball is in play, in bounds, to which side it belongs, and shall keep the time. He shall decide when a goal has been made and keep account of the goals with any other duties that are usually performed by a referee. The time shall be two fifteen minute halves, with five minutes rest between. The side making the most goals in that time is declared the winner. In case of a drew game may, by agreement of the captain, be continued until another goal is made. Naismith's original 1892 manuscript of the rules of basketball, one of the most expensive manuscripts in existence, is publicly displayed at Allen Fieldhouse on the campus of the University of Kansas. Naismith was the first coach in the history of Kansas Jayhawks men's basketball. Players, substitutes, teams and teammates Naismith's original rules did not specify how many players were to be on the court. In 1900, five players became standard, and players that were substituted were not allowed to re-enter the game. Players were allowed to re-enter a game once from 1921, and twice from 1934; such restrictions on substitutions were abolished in 1945 when substitutions became unlimited. Coaching was originally prohibited during the game, but from 1949, coaches were allowed to address players during a time-out. Originally a player was disqualified on his second foul. This limit became four fouls in 1911 and five fouls in 1945, still the case in most forms of basketball where the normal length of the game (before any overtime periods) is 40 minutes. When the normal length is 48 minutes (this is the case with the National Basketball Association in the United States and Canada) a player is accordingly disqualified on his sixth foul.
