The name, French for "the crook", is from the stick used. The modern game is played on a field 100 by 60 metres, with caged goals about.two metres square. A team consists of ten players:defence men, midfield players, attack players and a goalkeeper. The object is to score goals by carrying, throwing or batting a sponge rubber ball with the stick, which has a 25-centimetre net at the end. Only the goalkeeper may touch the ball with his hands, and the game is divided into four quarters of 15 minutes each.
