a massive fine-grained sandstone with thin soft bands, and at the 

 top are red and purple shales. It must be pointed out that the un- 

 conformity is not evidenced by any apparent discontinuity in succession, 

 nor is there any difference in dip between the two formations. 



Further north, at Yerkijkersberg, S.W. of Memel, the thickness of 

 the Red Beds has fallen to 100 feet. The red clays of the Upper 

 Beaufoi t lieds are succeeded by a bard gritty sandstone, often quartzose 

 at the base and this in turn by a fine-grained sandstone. Then 

 follows a series of red to purplish soft felspathic grits, red and greenish 

 shales and mudstones and soft white and red grits. The top of tin' 

 formation is formed of white medium-grained sandstones. The basal 

 sandstone is variable in thickness and rests sharply on red mudstone :

portions of it, especially at or near the base, are quartzose grits and 

 show false-bedding dipping in a South- Westerly direction. 



Midway between Harrismith and Memel, on Tandjes Berg, the lied 

 Beds are intermediate in thickness. 



Transkci. In the Transkei the thickness is uniformly 1200 feet. 

 The sandstones are gritty at the base of the series, occasionally carrying 

 isolated boulders of quartzite : higher up they become finer-grained 

 and yellow. The softer mudstones and sandstones and shales are 

 of brilliant red, purple, and blue tints, weathering pale. Many of 

 the so-called "buff" sandstones owe their colour to weathering, being- 

 red on a freshly-fractured face. 



Griqitaland East. In Maclear and the Divisions bordering it to the 

 North and East the thickness of the Red Beds diminishes from South 

 to North, having a maximum of 1200 feet, Du Toit has described 

 a section showing the full succession shown in the ascent from
