The water was struck under this rock in a few inches of a hard slaty 

 white bed at about 90 yards deep, and rose nearly to the surface. 



Mr. Sinclair states that the core brought up from this bed was so 

 much broken up that he is unable to say that it was limestone ; but from 

 the hardness of the few inches penetrated he is inclined to believe that 

 this was the case.
