The upper 100 ft. or so are brillantly coloured shales and sand- 

 stones. Calcareous rocks are fmpient, occurring usually as irregular 

 nodules and concretions in inudstones. 



North. The thickness measured at Kraai River I'oort is 

 <)00 feet, while to the north on the Herschel-Aliwal Boundary and 

 at Lady Grey it has fallen to (300 feet. The general features are 

 similar to those found further south. At the base of the beds a thick 

 yellow sandstone separates the Molteno Beds from the overlying 

 purple and red shales and rnudstones. The succession is well displayed 

 at Lady Grey, where Kynaston noted that the sandstones appear to 

 become liner-grained as one ascended in the series. Occasional layers 

 of calcareous concretions occur, which sometimes contain bone- 

 fragments. 





Barkly East. Only the top portion of the Red Beds is seen in 

 this mountainous district. The beds have a general dip to the South, 

 whilst to the north in Herschel, they dip in the opposite direction. 

 Du Toit noted the presence of much siliciiied wood on the farm 

 Glencoe, the tree stems being of considerable size. 



Herschel. The Red Beds are well displayed along the north side 

 of the \Yittebergen. The thickness at Palmiet Fontein (near the 

 liasutoland Border) and between Kromme Spruit and Majuba Nek is 

 at least !>00 feet. 



At the base are red and purple rnudstones, weathering to light 

 blue, which have yielded a number of large Dinosaur bones. At the 

 summit, at Dulcie's Nek, is a bed of limestone. Between, the strata 

 are made up of very brillant red shales and clays with prominent 

 red and occasionally bull' sandstones. The sandstone band which occurs 

 at about one-third the way up the succession as seen at Josana's 

 Hoek appeal's to be persistent and will probably prove a useful 

 "bench-mark' 1 for palaeontological purposes. 



Pebbles are very uncommon in the sandstones. During two fairly 

 extensive collecting expeditions which examined most of the outcrops 

 in the district only two reddish small semi-rounded pebbles of quartzite 

 were seen. 



Fossil wood is found in certain localities, occurring in the thin 

 sandstones Some of the trunks are large One section 9 feet long 

 now in the South African Museum has a diameter of over 2 feet. 

 It was found near the base of the formation at Kromme Spruit lying- 

 in a thin sandstone at a low angle to the bedding planes. Other
