of the Iff age was not long ago, geologically speaking, for equilibrium of the 

 disturbed areas has not yet been restored. Furthermore, the close parallelism in 

 the stages of progress toward repose indicates nearly the same time for the' end of 

 the Glacial period on both continents, and approximate synchronism in the pen- 

 dulum-like series of post-glacial oscillations.

NOTE OX THE MIDDLETON FORMATION OF TENNESSEE, MISSISSIPPI AND 



ALABAMA. 



BY JAMES M. SAFFORD. 



It i- known that in September last a party of geologists organized and carried out 

 an expedition having for its object the reexamination and study of typical sections 

 in Tennessee, Mississippi, Alabama and other southwestern states. The expedi- 

 tion, organized in Washington under able leadership, was a most successful one 

 and will be long remembered tor the pleasure it afforded all members of the party. 

 Its history lias been given elsewhere, and need not hi' repeated here. 



The party stopped lor a time at < >xford, the site of the university of Mississippi. 

 While here the writer caught sight of" some peculiar rock fragments containing 

 Eocene shells, which he thoughl must have come from localities known to him in 

 Tennessee. Dr. Hilgard, however, who was one of the party ami near at hand, 

 -aid they were from Mississippi, and pointed out the page in his "Agriculture 

 and Geology of Mississippi " (1860) on which the rock from which they came is 

 described. The rods is that indicated as '-clay-sandstone." division number 2 of 

 t he section on page II-. I >r. Eugene A. Smith, also a member of th ■ party, informed 

 ns that the same formation occurs in Alabama. 



The Tennessee rock is strikingly like that of .Mississippi ami could not be told 

 from it. [t occurs in Tennessee, in Hardeman county, a1 a number of points. One 

 of these is the town of Middletomon the Memphis and Charleston railroad, and 

 for many years I have spoken of it as the Middleton bed. 



And so it was that three of us, representing a- many state- -Tennessee, Missis- 

 sippi and Alabama -were, by a happy accident, thrown together and made to -,■,■ 

 that our several rocks were one and the same formation. 



The particular and characteristic rock referred to above is rarelj more than three 

 'eet i hick, hut it ha- associated with it a -roup of layers of much greater thickness. 

 The group hat" importance in the fact that it is the lowest Eocene in the states
