In these early years, each of the schools had their own versions of the game, and by the 1830s the version played at Shrewsbury had become known as "douling", taking this name from the Greek word for slave: the goal had no cross bar, favoured dribbling, and was being formally supported by the school's authorities to the extent it was compulsory. While, at the beginning of the 18th century, however, the school authorities deemed football "only fit for butchers boys", an attitude common at the other public schools, by the 1840s, all boarders were required to play Douling three times a week unless they were excused on medical grounds.
