The Umpire wears no color.

All being in readiness, the Umpire advances to the middle of the circle.
THE OPENING CEREMONY The Umpire places the ball in the exact center of the circle, then he gently urges it with his stick in a line toward the North until it reaches the edge of the circle.

There he picks it up and puts it back in the center of the circle.

Again he gently pushes it with his stick along a line toward the South until the edge of the circle is reached, when he returns the ball to the center of the circle with his hand.

In the same manner as before he sends the ball slowly along a line to the West.
