exact resemblance of several important peculiarities in this souter- 

 rain to those of Knock Dhu. A description has already been pub 

 lished and an admirable plan and section by Mr. Fennel shown in 

 vol. ii. of the second series of the "Ulster Journal of Archaeology." 

 Some time after its discovery, it occurred to the Rev. W. Adams, of 

 Antrim, to examine under the floor, just as it occurred to me 

 years later that it might be under the present floors of souterrains 

 that a key to the solution of the mystery attaching to them might 

 be found. Mr. Adams carefully excavated the floor and found 

 exactly in the place corresponding to the spot where the remains 

 were found in Knock Dhu. remains of a character almost exactly 

 similar to some of the remains found in Knock Dhu. There 

 was this difference. In Knock Dhu the charcoal layer was 

 permeated with burned bones and iron fragments ; in Boghead 

 the fire remains consisted of charcoal and pottery only. In 

 Knock Dhu were found, as already mentioned, remains of pottery 

 representing not only many different vessels, but vessels of 

 several distinct uses. Some were thick, heavily sooted both 

 inside and out ; vessels of moderate thickness sooted only 

 on the outside ; and thin vessels with no sign of soot at all. 

 The remains of vessels sooted inside and outside I shall refer to 

 later on, when I come to deal with the Eallykennedy find. The 

 remains of the vessels sooted on the outside only, we came to the 

 conclusion, afterwards proved by the Donegore find, were those of 

 cooking pots In Boghead, Mr. Adams found pieces of one pot 

 only, of the latter class. These he carefully pieced together with 

 the admirable result shown in section 2. I have to thank Mr. 

 Adams for his kindness in lending this vessel for exhibition, and 

 for the benefit of his valuable experience in helping in my inves- 

 tigations. 



Of the third type of pottery found in Knock Dhu souterrain, 

 the thin hard ware bearing no marks of soot, one fragment show- 

 ing both the lip and bottom was found, from which we are able 

 to tell its exact size and shnpe. To illustrate its probable use 

 more clearly I asked Mr. Cox, of India Street, to restore it com- 

 pletely. This class of the pottery is evidently the ordinary domestic
