Introduction. 



Progress in other States. — Through the intelligent exertions 

 of Smith, Aldrich and others, the Tertiary Geology (including 

 paleontology and stratigraphy) of Alabama is fairly well known. 

 Hilgard pointed out the general scheme of Mississippi stratigra- 

 phy long ago. Recent surveys are bringing to light the true 

 disposition of the various Tertiary terranes on the Gulf west of 

 the Mississippi. 



Georgia behind the other States. — Our knowledge of the Ter- 

 tiaries of Georgia, however, is most deplorably small. About the 

 Florida line, to be sure, as well as along the Chattahoochee, the 

 Alabama line, a few facts have been noted that are important so 

 far as they go. Spencer while State Geologist, published a map 

 of western Georgia on which the subdivisions of the Eocene, 

 worked out in Alabama, were made to pass up to the northeast in 

 a fairly regular manner to the eastern border of his map. So far 

 as the distribution of the stages of the Eocene is concerned on 

 that map, it is wholly hypothetical and bears almost no semblance 

 to the truth. The beds he represents, upon the Chattahoochee, 

 are very quickly blanketed under a northern extension of the 

 Oligocene as has been indicated, though on a small scale map, in
