HA-HA is a sunk fence, being placed 

 at the bottom of a deep and spreading 

 ditch, either to avoid any interruption to 

 an expanse of surface, or to let in a de 

 sired prospect. As all deceptions are un- 

 satisfactory to good taste, and as, when 

 viewed lengthwise, these fences are 

 formal and displeasing, they ought never 

 to be adopted except in extreme cases.
