I.v 



underlving rocks are then either granite or soft sediments of the 

 Mahnesbury or Frencli Hoek Series. The actual foundation on 

 which the Sandstone hes can be seen at a few points ; thus round 

 the foot of the chfifs on Bootman's Kop the granite appears im- 

 mediately below the sandstone. The junction of the Table 

 Mountain Series with the eroded surface of the Malmesbury 

 Beds is seldom clearly visible, but in a kloof on the farm Niet- 

 Gegund. on the west side of Stellen'bo.sch. Mountain, this uncon- 

 formable junction is almost completely exposed. A sketch of 

 the junction is given in Fig. 6. 



The lowest beds of the Table Mountain Series are often 

 brightly coloured, and contain much argillaceous matter ; refl and 

 brown shaly sandstones, just like those seen at the base of the 

 Lion's Head, occur in the lower hundred f^et of the series on 

 Bootman's Kop. Thin pebble-bands occur all through the series; 

 false-bedding is common, and rip])le-marks not unusual.

The dip of the beds is very low or nearly zero around Stel- 

 lenbosch. On Stellenbosch Mountain itself there is a very 

 gentle north-east dip, which increases further up Jonker's Hoek. 

 Only a few miles away, however, at French Hoek and Sir Lowry 

 Pass, the folding is already severe. 



The (tkamtf. 



of the neighbourhood occurs in three masses, or. rather, 

 three lobes of what is just one large batholith. There is nothing 

 whatever to indicate that the different lobes were not all in- 

 truded at one and the same time. 



To the west is the large area of granite which stretches from 

 Bottelary Hill to Somerset West, and from Papegaaisberg, 

 nearly to Kuil's River. The granite is seen immediately one 

 crosses Plankenberg River by the road-bridge at Bosnian's Cross- 

 ing. It is a coarse, por])hyritic variety, indistinguishable in
