128 CELTIC EEMAINS ON DARTMOOR. 



small Circles ; they are the bases of Huts. In Yorkshire, together 

 with similar Eaised Circles, I have seen another mode of making 

 the dwellings, by sinking a circular hollow five or six feet deep, 

 and in some cases lining it with stones ; and it is possible that 

 the roof was flat. However, the two are only diff"erent modes 

 of constructing the same shaped and sized dwelling-places. I 

 think it probable that similar places of habitation formerly ex- 

 isted upon the lower grounds, cultivation having destroyed all 

 traces of them, as I have known it to destroy all evidences ot 

 larger Camps, with Mounds eight or nine feet high. — In North- 

 umberland, those left are on the higher ground, because the 

 plough has never touched it ; but I have no doubt that at one 

 time they existed over the whole country. I take them to have 

 been the habitations of the early tribes, who might, on Dart- 

 moor, have been employed in working Tin, but who, no doubt, 

 also lived on the higher ground, where game abounded, and 

 where they were able to find more suitable places for defence 

 against an enemy. In Northumberland they have no connexion 

 with any mining operations. Cultivation explains their absence 

 in the fertile parts ; its never having been used on the hiUs ac- 

 counts for their being found there."
