230 " STRANDLCXM'ER "* POTTERY AT DUNBRODY. 



upon shales or sandstones Ijelongino- to the Uitenhage series. 

 It is a typical river formation, showing in its gravel beds water- 

 worn stones of all sizes. 



To the south the plateau slopes down to the Sunday's River 

 and becomes identified with the present bank of that river. 

 which exhibits the same intermingling of river gravel and sand. 



At the spot where the find of pottery was made, the White 

 River is eating into the clifif-like edge of the plateau, and every 

 flood sees some new portion of the clifif undermined. 



Except when in flood, the stream has no such destructive 

 action on the clifif, as it.s base for some feet above the ordinary 

 water-level consists of hard shale. 



P0.SIT10N OF THE Pottery. 



The pottery was found in the face of the cliff, some 20 feet 

 above the water-level and 6 feet from the present top of the 

 cliff. Its presence was first made known by the finding of frag- 

 ments which had fallen to the base of the cliff. 



The deix)sit itself was a bed of broken shells mixed witli 

 fragments of pottery. d"he bed was only two or three inches in 

 thickness, and occujiied a horizontal area estimated at about 

 6 feet by 3 feet. (Text-figure 2.)

Nature of the Deposit. 



The shells which comjxised the greater part of the material 

 of which the deposit was made up were exclusively those of the 

 freshwater mussel, Cafferia caffcr Krss., as identified at the 

 Albany Museum. Some of the shells were calcined and reduced 

 to a white powder. The jx>ttery was scattered among the shells 

 in broken pieces. N<:) stones, which could even probably be 

 identified as artefacts, occurred in the deposit.
