Mr. Lilley says in his letter that Granville Centre is on ground 250 feet 

 lower (geologically) than the township line. Between the two is an 

 exposure of about 150 feet ot shale and sandstone containing Orthis, Cho- 

 netes, Cyprieardites, Tentaculites, Pterinea, Trigonia and Rhynchonella. 



He adds that Adam Dennis has recently bored a six-inch hole for water 

 to supply his tannery, on the south side of the stream near Granville Cen- 

 tre. It is ninty-six feet deep ; and the bottom thirteen feet was in blue 

 shale and sandstone. 



By combining these data the original section was enlarged and improved. 

 But Mr. Lilley has used every opportunity during the last two years to 

 increase its value, and has found forms which he is unable to name.
