EAST WEAK BAY. 51 



by instalments. Under your band the gault divides 

 itself into little cubical blocks, and the shells are all 

 disintegrated. Follow the tide as it goes out, and 

 icork in the icet clay. 



The section exposed from the Harbour at East 

 Cliff, and stretching eastward towards Dover, is a 

 good one, and highly instructive to the young 

 geologist. I have mentioned the general nature of 

 the cliffs in the Lower Sandgate Eoad in a former 

 ramble. These cliffs are but a continuation of them, 

 Old Folkestone standing in a valley formed by some 

 river cutting through them in ancient times. They 

 belong to the Folkestone Beds the upper division of 

 the Lower Greensand, or, as some prefer to call them 

 the Neocomian Beds. A few fossil oysters and tere- 

 bratulae, with an occasional pecten, &c., may with 

 difficulty be extracted from them. They dip rapidly 

 here into the sea, you may follow the rocky strata 

 down to low- water mark. 



Above them conies the Gault, but between the two 

 a curious bed known as the Junction Bed, about 

 eighteen inches thick, variegated with yellow, red and 

 black, and glittering with crystals of selenite and 

 iron pyrites ; full, as full as it can be, of phosphatic 

 uodules with which are mixed ammonites and black 

 wood bored by ancient worms. Large lumps of 

 selenite may be found among the rocks at the foot of 

 the cliffs. What is the origin of all these nodules so 

 highly charged with phosphate of lime ? Since, so 

 far as we know, this substance is mostly an animal 

 production in Nature, they would appear to tell of 

 the decayed remains of countless generations of 

 creatures which had lived in the old Gault seas.
