xxv. Where there is no umpire present, permission to move a ball, or

to set up a hoop or peg or other indulgence for which an umpire would have been appealed to, must be asked of the other side.

xxvi. The decision of the umpire shall in all cases be final. His duties are:

(_a_) To move the clips, or see that they are properly moved;

(_b_) to decide on the application of the laws;

(_c_) to satisfy any player as to the point that is next to be made, or the right ball to play;

(_d_) to keep the score. But he shall not give his opinion, or notice any error that may be made, unless appealed to by one of the players.
