At a short distance below this a thin yellow band^ such as No. 5, 

 dips beneath the clay, and some large slabs broken from a highly sili- 

 cious bed occur in a heavy bank of debris flanking the trap hiU, while 

 within one hundred yards to the northwards, the pale greenish gray traps, 

 rudely columnar in places, are overlaid by some reddish, mottled, soft 

 laterite or earthy beds, both dipping (so as to underlie the section above 

 given) southwards at 20." 



The blue clay No. 1 is quite dry and full of carbonaceous and 

 rusty remains of plant stems. It contains many prismatic and octo- 

 hedral crystals of gypsum. The under surface of the yellow compact 

 band. No. 5, is studded with crooked annelid tubes in relief, tangled 

 with crystalline patches of gypsum. 



Gypseous shales. 



To the eastward within a short distance, the lower shales are 

 highly gypseous, quantities of the clear mineral 

 weathered out lying about the ground. On the 

 northern bank of the stream, and further in that direction near the 

 Alum store-house and boiling place, another fossihferous band occurs 

 overlying a black carbonaceous shale, and underneath another gypseous 

 shaly band. The white earthy rocks of the lateritic sub-nummulitic 

 series appear to the northward between these beds and the trap hill.
