<P> The croquet lawn existed on the northern terrace , between Eglinton Castle and the Lugton Water . The 13th Earl developed a variation on croquet named Captain Moreton 's Eglinton Castle croquet , which had small bells on the eight hoops `` to ring the changes '' , two pegs , a double hoop with a bell and two tunnels for the ball to pass through . In 1865 the ' Rules of the Eglinton Castle and Cassiobury Croquet ' was published by Edmund Routledge . Several incomplete sets of this form of croquet are known to exist , and one complete set is still used for demonstration games in the West of Scotland . </P>
