The water found in this lowest bed, although apparently 

 less saline than that above it, was not suitable for general use. 



While the method of boring employed was not the best for 

 keeping the fossils of each stratum entirely separated from 

 those below it, yet the anchoring of the different sizes of pipe 

 at the depths given has acted as a partial safeguard against the 

 commingling of the faunas of those different zones. 



The fossils secured by the untiring watchfulness of Mr. 

 Singley were numerous and varied, comprising many parts of 

 plants, fruits, a pine cone, etc., fish remains and a large number 

 of invertebrate forms. The shells were turned over to Mr. 

 Gilbert D. Harris for examination, and his preliminary report 

 is given herewith. 



The results of the investigation add a most important chapter 

 to our knowledge of the history of the formation of the Gulf 

 coast, and furnish a section for reference and comparison which 

 could have been obtained in no other way. 



The thickness of the different members of the series as 

 stated by Mr. Harris indicates either a greater dip than we 

 have hitherto supposed to be the case in these deposits or else
