is undertaken by Beaks (Harrow Masters), House Masters and senior boys. Playing field Harrow Football is usually played on a pitch similar to rugby or association football pitch. The pitch can be muddy, wet, and even waterlogged. It is usually 100-130 yards (90-120m) in length by 50-100 yards (45-90m) in width. The pitch must be rectangular, with the length (touch lines) longer than the width (goal lines). On the goal line at each end of the field is a 'base' which looks like rugby posts with their crossbar removed so a base may be scored at any point through them. The inner edges of the base posts must be apart. The field has no other field markings, except for a half-way line which spans the width of the pitch and is equidistant from each goal line. Duration A standard Harrow football match consists of two periods (known as halves) of 40 minutes each. There is usually a 15-minute break between halves, known as half time. The end of the match is known as full-time. Boshing Boshing is the form of Tackle used in Harrow Football. It is performed by a member of either the defensive or the offensive side, and its use is warranted by being within a reasonable distance from the ball. To perform a bosh, a member of one side shoulder barges a member of the opposition. There are several limitations to the bosh, as the bosher may not raise his arms or use his elbows, and it must be performed from either the front or the side (not behind). Any breach of these rules results in a Foul. Starts and re-starts Each playing period in Harrow football commences with a kick-off, which is a set kick from the centre by one team. The person kicking the ball does so by dropping it from his hands. At the kick-off all players are required to be in their half of the field until the ball is kicked. Kick-offs are also used to restart play following a base, though the team kicking off also has the option of dribbling the ball rather than kicking it. Teams alternate taking the kick-off after each base, regardless of which team scored the base. The only exception is after half time, when the team who did not kick-off at the beginning of the match takes the kick. From the initial kick-off of a period
