(A) Horizon of Salt Bed. 



(B) Feeder of brine of strength 21°/^, quantity imknown, but persistent at a 

 depth of 1150 ft. in the Magnesian Limestone. It is supposed by the Engineer 

 to the boring that this brine drains from the Salt -bed iuthe Trias on the soath, 



]S"0TE. — So far as Eock-Salt is concerned this boring was a failure, but for 

 the brine, and in other directions possibly, it is thought the undertaking may 

 be commercially remuneratiye. 



The Magnesian Limestone dips pretty regularly at 3°. The Coal-measures 

 hare an inclination of about 6°. K'o fossils were detected in the cores of 

 Magnesian Limestone or of the oS^ew Bed Sandstone. The occurrence of 

 gypsum and anhj'drite in considerable quantities, in association with the 

 Magnesian Limestone, is a noticeable feature in this Section.
