Below 17 feet Mr. Reid's account (for which I have to thank the 

 Geological Survey) differs, being more detailed and as follows : — 



Clean buff sand 



Blue silt 



Coarse gravelly sand 



Brown silt 



Bluish sand 



Shingle 



Gravelly sand (Mytilus, Mya, Cyprina, at 120 feet ; 

 Trop'hon at 137 ; Mya at 150 ; Cyprina at 153) ... 



Gravelly sand, full of fossils : — Aporrhais pes-pelecani, 

 Littorina littorea, Trophon antiquus (dextral), As- 

 tarie compressa, A. sulcata, Gardium, Cyprina, 

 islandica, Mactra ovalis, Mya arenaria, Mytilus, 

 Pecteti opercular/s, Pcctiineulus f/lyciiiieris, Tellina 

 obliqua, fish-bones < 



From this it is clear that the Crag reaches to 

 200 feet. The next section shows that it goes 

 240 feet.

a depth of over

Lowestoft. Ice- works, near Lake Lothing. 1902. 



Made and communicated by Messrs. Tilley. (Remarks in 

 parentheses made from specimens.) 



A good supply of water was got between 4S0 and 550 feet down, 

 but unfortunately it contained much magnesia. A fresh set of 



tubes was driven down to 490 feet, to shut off this water, 

 depth the Chalk is practically waterless.
