Polo
Polo, an equestrian game of hockey, was practised from a remote antiquity in the East, and was introduced into Calcutta by British officers in 1863. It has now been generally adopted among British communities. The polo-ground should be of turf, 300 feet by 200 feet, with goals at each end 22 feet apart. The ponies used should not be more than fourteen hands high, nor the players more than four a side, consisting of 1, 2, 3, and back. The polo-stick - four feet long - is of light cane, with a cross-head eight inches long, and the ball is of light wood. A player is not allowed to cross the front of his opponent.
