The gully fielder is an extension of the line of slips and fields almost square to the batsman; gully is also the name given to that area of the field. A fielder standing in gully would be standing on the imaginary straight line that extends from the on-side corner of batter's popping crease to middle stump towards the slip cordon. The position of gully was invented in the 1880s by Arthur Jones, who later became England captain, at Bedford Modern School in Bedford. It was quickly adopted by EHD Sewell at Bedford School and then gained in popularity thereafter.
