The classification of defensive works as recommended by the 

 Committee now stands as follows : 



.\. Fortresses partly inaccessible, by reason of precipices, 

 cliffs, or water, additionally defended by artificial works, 

 usually known as promontory fortresses. 



B. Fortresses on hill-tops with artificial dciences, following the 

 natural line of the hill ; 



Or, though usually on high ground, less dependent on 

 natural slopes for protection. 



c. Rectangular or other simple enclosures, including forts and 

 towns of the Romano-British period. 



D. Forts consisting only of a mount with encircling ditch or 



■fosse. 



E. Fortified mounts, either artificial or partly natural, with 



traces of an attached court or bailey, or of two or more 

 such courts. 



F. Homestead moats, such as abound in some lowland 



districts, consisting of simple enclosures formed into 

 artificial islands by water moats. 



c. Enclosures, mostly rectangular, partaking of the form 

 of F, but protected by stronger defensive works, ram- 

 parted and fossed, and in some instances provided with 



outworks. 



H. Ancient Village sites protected by walls, ramparts or fosses. 

 X. Defensive works which fall under none of these headings. 



Any further information will be given by the Honorary Secretary.
