Four years ago I laid before the Society some evidence of glacial 

 action in the Table Mountain series from the Pakhuis Pass near 

 Clanwilliam. I have lately had an opportunity of searching the 

 western flank of the Cederberg range for more outcrops of the 

 conglomerate, and I traced the rock in question over an area, 

 fifteen miles in length and about seven in width. The total length 

 of the lines along which the conglomerate has been followed,, 

 including the frequent intervals between outcrops, where the rock 

 is concealed beneath the soil and fallen debris, is twenty-three miles. 

 Even where the rock itself is not visible the form of the ground 

 indicates its presence. 



A visit to the Pakhuis Pass was not rewarded by the finding of 

 any additional exposures to those described in the earlier com- 

 munication. 



From Botha's Berg the clearly-marked feature on the mountain 

 slope, caused by the presence of the shale band, at the base of 

 which the conglomerate occurs, was followed west-north-west 

 through Rheebok's Vley, Vark Fontein Extension, Klein VJey 

 Extension, Klein Vley, Zand Kraal Extension, to Lange Kloof, on the
