An analysis of the above table indicates that, as far as a ma- 

 jority of its generic elements are concerned, the flora of the 

 Saint Eugene silts might be regarded as Pleistocene in age ; and 

 certain of the genera most abundantly represented by actual 

 number of specimens {Fagus, Hicoria, and Platanus) are also 

 among the most characteristic genera of recognized American 

 Pleistocene deposits. Specifically, however, the flora can not be 

 satisfactorily correlated with any Pleistocene flora heretofore 

 described. All of the species are, apparently, new to science, 

 and their prevailingly large size indicates a more luxuriant or 

 vigorous growth than is indicated by figures of related species 

 recorded and described as Pleistocene in age in connection with 

 any American deposits. The specific elements might represent 

 a Tertiary flora, as far as their general surficial characters are
