CLASS X. 

 Defensive or other works which fall under none of the above headings. 



Though it was the original intention to confine investigations to purely 

 defensive works, those who have been working on the maps, or in the field, 

 have found it easy at the same time to schedule tumuli, boundary-banks, 

 dykes, etc. It is therefore suggested that a list of all such remains should 

 be compiled.
