304 E. A. Smith—Geology of Florida. 
So far as I know, this article contains also the first published 
record of observations upon the geology of any part of Middle 
or Western Florida, and the first account of the discovery of 
Miocene strata in the State. For these reasons it has seemed - 
worth while to publish the foregoing notes. 
Leaving out of consideration, for the present, the beds of 
stratified drift, it appears further, that along the Gulf coasts of 
Alabama, of West Florida and of the Peninsula, the Post- 
Pliocene strata are directly superimposed upon the Vicksburg 
limestone; the intervening beds, representing the Miocene and 
Pliocene, being, so far as we now know, absent from those 
ocalities 
On the other hand, we know that in one locality certainly, 
and presumbly elsewhere along the Atlantic slope o the 
peninsula, a Miocene limestone overlies the Vicksburg. 
While rocks of Pliocene age have not yet been recognized, 
it is reasonable to suppose that future explorations will reveal 
their existence along the eastern coast in a position similar to 
that occupied by beds of the same age in Georgia and South 
Carolina. 
The facts with regard to the distribution of the rocks of 
Florida are presented in the following map. 
Those points where the existence of the Vicksburg limestone 
has been determined beyond doubt, by fossils collected and 
fk 
will probably be found. : 
Professor Tuomey states that the Vicksburg limestone 
probably the country rock as far south as Charlotte Harbor. 
Below that latitude, however, to the Hverglades, the forma- 
tion is a matter of conjecture, though laid down as probably 
of Vicksburg age. . 
In how far the construction of the map is justified b the 
facts observed, the reader has thus the opportunity of Ju ging 
for himself.
