﻿0. Meyer — Tertiary and Grand Gulf of Mississippi. 23 



7. In Newton, Newton County, at the Vicksburg & Meridian 

 Kailroad, laminated clays dipping east, apparently belonging 

 to the Grand Gulf formation, may be seen. Three miles east 

 of Newton there is a vertical railroad cut two hundred feet long 

 and about fifty feet high affording the following profile : 



(c) Clayey green sands of varying quality, sometimes 

 with hard ledge-like nodules, numerous well preserved 



fossil 6 ; nearly. _ 40 feet 



(b) Reddish sand, somewhat lignitic __ 4 feet 



(a) Laminated clays^ cross-bedded with pockets of sand. 

 They either alternate with or are overlaid by lignitic 

 sandy clays or clayey sands, scarcely stratified, with 

 numerous lignitized plants and roots erect in natural 

 position 10 feet 



The stratum u c" is seen on the surface 1,000 feet west from 

 the cut on the railroad track, and therefore the dip must be 

 west. I collected in this stratum "c," in less than a day, 105 

 species of fossils. The position of the lignitized plants in 

 the stratum "a" shows that they grew on the spot, apparently 

 in very shallow water (swamp ?). 



The above is the account of my efforts at eight different 

 points to find the contact of the Grand Gulf beds and the 

 Tertiary, The following observations are less directly con- 

 nected with this question. 



Greensands south of Enterprise. 



The same clayey greensands, mentioned above, from Newton 

 (stratum u c") occur in cuts of the railroad between Meridian 

 and New Orleans, four miles south of Enterprise near Wautub- 

 bee, and are here underlaid by white, micaceous, cross bedded 

 sands, which attain a thickness of at least twenty feet and 

 sometimes contain clays. These greensands are here very vari- 

 able in thickness and in petrographic and paleontological 

 qualities. Sometimes they are clayey, sometimes stratified, 

 hardened and lignitic. At one point occurs the same ledge- 

 like nodules as in Newton, containing Ostrea sellceformis C. 

 I collected here 110 species, agreeing mostly, although not 

 entirely, with those in Newton, among them two species of 

 Cephalopods. The description of this Wautubbee-Newton 

 fauna will appear in the Journal of the Cincinnati Society of 

 Natural History for July, 1886. If I am not mistaken the same 

 bed occurs at the tunnel west of Meridian and I think it is 

 identical with a greensand bed which can be seen on the Chick- 

 asawhay at the bridge in Enterprise, underlying my bed "&"* 

 (Claiborne profile). If this is so, the bed ranges stratigraphi-
