Appendix III. 



The Haerfaulds. By Francis Lynn, F.S.A. (Scot.), Galashiels. 



(Plate XXII.) 



The Haerfaulds is a strong enclosure built of stone, without 

 any appearance of outer ditch. Along its south-east side its 

 walls follow the summit of a rocky ridge or ledge, worn out 

 or torn out by the ice stream in the glacial age. On the 

 south-west the ground falls steeply to the Blythe water. On 

 these sides the position being strong the walls are of moderate 

 strength; but along the north side, where the ground surface 

 rises gently above tlie fort, the walls are of great thickness. 

 At the north-west angle the thickness is 12 feet. On the 

 north-east corner it varies from 1 1 to 18 feet, but about the 

 middle of the north wall it widens out to 32 feet. It is difficult 

 to be sure of the exact line on the inner side of the building, 

 the stones having been removed in great quantities, and the 

 face of the building broken up. The plan given by Mr Milne 

 Home (the father of our late Secretary), which is used by 

 Dr Christison in his works, shows the wall as of uniform 

 thickness all round, with circles built inside and abutting on 

 the outer wall. But Mr Home had thought that some of 

 these circular buildings had been recessed inside the wall. 

 Dr Christison does not agree with this view, but I myself 

 am of opinion that Mr Home was right. Chambers in the 

 thickness of walls are not rare. Greaves Ash in Breamish 

 Water shows them unmistakably, and they are distinct in 

 the north wall of Blackchester Fort, above Lauder. There 

 are suggestions of the same thing at Longcroft. But these 

 cells are introduced with a regularity that is strikingly absent 

 iu the design of those at Haerfaulds.
