The puck may be stopped by any part of the person but not carried or knocked except with the stick. No stick may be raised above the shoulder except when actually striking the puck. When the puck is driven off the rink or behind the goal, or a foul has been made behind the goal, it is faced 5 yds. inside the rink. The goal-keeper must maintain a standing position. There are a number of Hockey organizations in America, all under the jurisdiction of the "American Amateur Hockey League" in the United States and the "Canadian Amateur Athletic League" in Canada. _Ice Polo_, a winter sport similar to Ice Hockey, is almost exclusively played in the New England states. A rubber-covered ball is used and the stick is heavier than that used in Ice Hockey. The radical difference between the two games is that, in Ice Polo, there is no strict off-side rule, so that passes and shots at goal may come from any and often the most unexpected direction. Five men constitute a team: a goal-tend, a half-back, a centre and two rushers. The rushers must be rapid skaters, adepts in dribbling and passing and good goal shots. The centre supports the rushers, passing the ball to them or trying for goal himself. The half-back is the first defence and the goal-tend the last. The rink is 150 ft. long. _Ring Hockey_ may be played on the floor of any gymnasium or large room by teams of six, comprising a goal-keeper, a quarter, three forwards and a centre. The goals consist of two uprights 3 ft. high and 4 ft. apart. The ring, which takes the place of the ball or puck, is made of flexible rubber, and is 5 in. in diameter with a 3-in. opening through the centre. It weighs between 12 and 16 oz. The stick is a wand of light but tough wood, between 36 and 40 in. long, about 3/4 in. in diameter, provided with a 5-in. guard 20 in. from the lower end. The method of shooting is to insert the end of the stick in the hole of the ring and drive it towards the goal. A goal shot from the field counts one point, a goal from a foul 1/2 point. When a foul is called by the referee a player of the opposing side is allowed a free shot for goal from any point on the quarter line. _Roller Polo_, played extensively during the winter months in the United States, is practically Ice Polo adapted to the floors of gymnasiums and halls, the players, five on a side, wearing roller-skates. The first professional league was organized in 1883.
