On a Glacial Conglomerate in the Table Mountain Sandstone. 237 
On a farm called Bailie’s Gat in the southern part of the Cederbergen 
(in the field-cornetcy Scotland, of the Ceres Division) a bridle-path 
has been cut across a steep slope made of the shale band; the rock 
is exposed for some twenty yards along the path, and is a grey or 
brown shale with red and yellow stains very similar to some of the 
beds belonging to the Bokkeveld formation. North of the farm 
Pakhuis a similar rock is seen in a road cutting, and also in a cutting 
on the main road between Piquetberg Road and Clanwilliam, in the 
Olifants River Valley. At Bailie’s Gat the shale band lies about 
1,000 feet below the top of the Table Mountain Sandstone, but 
further south there seems to be less sandstone above it, although the 
thickness is difficult to estimate closely, both on account of the vary- 
ing dip of the beds and the rugged nature of the country. The 
thickness of the shale band itself is also difficult to estimate, as the 
exact top and bottom of it are never seen, but it probably varies from 
200 to 500 feet. 
West of Clanwillian the Table Mountain Sandstone forms a broad 
anticline trending north-west, and sinking in the same direction, so 
that the beds dip some few degrees north of north-east, and west of 
south-west, on the two sides of the axis. Near the village the sand- 
stone is faulted against the Bokkeveld Beds, which form the so- 
called Karroo hill, but further up the Olifants River it dips normally 
under an outlier of those beds. Similarly on the north-east side of 
the anticline, the Bokkeveld Beds have been let down against the 
sandstone between the farms Hoender Fontein and Welbedacht, 
while both to the north and south the usual conformable passage 
between the two formations is met with. 
The road from Clanwilliam goes through the farms Klein Kliphuis, 
Rheebok’s Valley, round the south end of Botha’s Berg on to the 
farm Pakhuis. Between the houses on Rheebok’s Valley and 
Pakhuis the road is carried along the curved outcrop of the shale 
band, and the rock is exposed at intervals through a distance of 
about three miles and a half. To the north-west of Rheebok’s 
Valley the shale band is marked by a bushy, débris-covered slope, 
which lies on the north-east side of the Kliphuis River; above the 
slope is a continuous cliff, which terminates southwards in Botha’s 
Berg. To the north-east of Botha’s Berg the shale band sinks into 
the Pakhuis Valley, where it forms the flat ground on which the farm 
stands. From Pakhuis the band trends south-east towards Kraka- 
douw, up the Pakhuis River. 
The road between Rheebok’s Valley and Pakhuis lies on the 
lower part of the shale band, for outcrops of the underlying sand- 
stone are seen on the hillside immediately below the road near
