72 PAPJÜR8, ETC. 



I think, be no doubt that these three fortifications, which I 

 bave described, are specimens of two perfectly distinct 

 types, the one with its series of concentric fortifications, 

 reminding us of the plan of an Edwardian castle, and by 

 the absence of all independent enclosures, leading us to 

 suppose that they were constructed entirely for warlike 

 purposes ; while the other, with its several enclosures, is 

 more like the Norman plan of fortification, less purely 

 devoted to military views, and containing within its out- 

 works arrangements rather suited to the convenience of 

 the occupiers than to the rnere strength of the fortress. 



The question which naturally arises from these facts is 

 this : Are these types merely the difference between a 

 purely military work, and one also intended for convenient 

 habitation, common to all the inhabitants of Britain? or do 

 they mark the difference of taste or nation of the con- 

 structors of these very different works ? In the total 

 absence of written history, and at this great distance of 

 time, it is probable that this difficulty can never be satisfac- 

 torily cleared up. I will, however, venture to lay before 

 you a few observations which have occurred to me on the 

 subject ; but before doing so, I must beg you to observe 

 that the very crude theory which I am about to suggest is 

 one brought forward in the hope that it may either be 

 confirmed or refuted by the investigations of others who 

 may be inclined to take up that very interesting pursuit, 

 which circumstances compel me most unwillingly to relin- 

 quish. 



It would certainly be a great step towards the Solution 

 of the difficulty if we could conncct either or both these 

 types of fortification with any known historical fact, and I 

 cannot but hope that what I am about to mcntion may aid 

 up in doine *o.
