Eocene at Old Port Cdildo Lmid/iKj. — \' (iiKjlKni. 'MM 
Marshall, Texas, which has an altitude of 875 feet (from T. 
& P. R'y elevations), an area of the marine beds occurs. The 
beds at Port Caddo, at least in their lower i)ortion, are litho- 
logically like those called "Lignitic." From these data it 
would seem that there is little doubt regarding the correct- 
ness of the age that is suggested, for the lower jiart of this 
section. 
The Eocene fossil plants otfer a most interesting Held for 
study, as probably they will ultimately aid us in the correla- 
tion of our great southern plant-bearing beds with the i)lant- 
bearing beds of the west. Prof. Knowlton's accompanying- 
report shows this, and Messrs. Penrose* and Hillf have made 
important remarks bearing on the same problem. From Lou- 
isiana Lesquereux]; has identified fossil plants collected at two 
localities. 
In the following table I have placed alongside each other tiic 
lists from Lesquereux's i)aper and from Prof. Knowlton's:
