line named the Dead Line.

The Side-Lines extended from Goal-Line to Dead-Line shall be named
the Side-Lines-in-Goal.

Side-Lines-in-Goal shall be named the Goal Area.

The Bounds shall be defined as the "inside" of the side-lines,

The field-of-play shall be marked every 5 yards with lines extending
from side-line to side-line and parallel to the goal-lines.

Twenty-four yards in from each side-line each 5 yard stripe shall be
marked by a short cross stripe parallel to the side-lines (Hash Marks).

Markers shall be placed opposite each 5 yard line from the goal-line,
indicating the distance of each such line from the goal-line toward the
centre of the field.

The four intersections of goal-lines and sidelines and the four
intersections of deadlines and sidelines-in-goal shall be indicated by
flexible markers which must be so placed that they are not touching the
surface of the playing field.

Article 2: Fields Less Than Regulation Size

track or object. A line shall be painted on the playing surface and shall
be considered as the boundary line. A player who touches this line, the
surface outside the line or any object outside the line shall be ruled as
having gone out of bounds.
