SHORTER C0"NTRIBUnONS TO GENERAL OEOLOGY, 1921. 



The flora, as at present known, is inaiioqiiato 

 to indicate the environment in which the plants 

 lived, but it clearly contains no unusual fea- 

 tures, and I can see no reasons for supposing 

 that the physical conditions were different 

 from those which have 1)een predicativl from 

 the much lar<;or floras of the Tuscaloosa. Rari- 

 tan. and Ma<ji>thv formations, which have been 

 discussed at length in various publications.
