Hey up me Duck,old D.H. here ’appen tha’ll want to know what a ha ha is? Well the ha-ha or sunken fence is a type of boundary to a garden, pleasure-ground, or park, designed not to interrupt the view and to be invisible until seen from close by. A ha-ha consists of a trench, the inner side of which is vertical and faced with stone, with the outer slope face sloped and turfed, making the trench, in effect, a sunken fence or wall. ‘Appen Kate dislikes the beastly bourgeois as much as me’sen (see below).
