Meanwhile, the British Empire had been instrumental in spreading the game overseas and by the middle of the 19th century it had become well established in Australia, the Caribbean, India, New Zealand, North America and South Africa. In 1844, the first-ever international match took place between the United States and Canada. In 1859, a team of English players went to North America on the first overseas tour.
In the approximate centre of the field is a rectangular pitch (see image, below) on which a wooden target called a wicket is sited at each end; the wickets are placed 22 yards (20 m) apart. The pitch is a flat surface 3 metres (9.8 ft) wide, with very short grass that tends to be worn away as the game progresses (cricket can also be played on artificial surfaces, notably matting). Each wicket is made of three wooden stumps topped by two bails.
