Below the depth of 715 feet no fossils appear till 778 feet, but 

 the nature of the fossils there encountered do not permit of a 

 decisive determination as to age, and this also applies to other 

 occurrences. It is not until the fossiliferous bed at 970-1,000 feet 

 is reached that undoubted e^ idence of Eocene age is forthcoming, 

 which continues to 1,681 feet, the greatest depth yielding fossils.
