vey, and observations were extende<l over all the adjoining country, 
and tlie proper relations of the river sections were carefully made out, 
photographs for the illustrations were taken, and tho whole Tertiary 
and Cretaceous sections were carefully made out and verified. Ilesults 
of the work done by the Alabama survey during 1880 and 1881 and 1882 
were incorporated, so that the present bulletin represents, in addition 
to the two weeks' joint work nf the two surveys, the results of six sea- 
sons' summer work of the Alabama Survey alone. It is tliis later work 
of the Alabama Survey which gives the Bulletin mo.stof its value, and 
has changed it from a very imperfect sketch, to a fairly complete and 
trustworthy section of ail the strata of Cretaceous and Tertiary age ap- 
pearing in the vicinity of the two rivers. 
Prof. Tuomey in 185(>, coming from the fields of South Carolina, found 
in Alabama the series of rocks identical with those which, in South 
Carolina under the name of Buhrstone, were at the base of the Ter- 
tiary formation. He accordingly considered the Buhrstone as the basal 
rocks of the Alabama Tertiary also. In 1S72, Dr. Smith made his first 
excursion into this territory and foun<l that there were many feet of 
strata underlying the Buhrstone. This conclusion was communicated 
to Prof. Heilprin, to whom Dr Smith sent a number of new shells from 
one of the sub-Buhrstone beds, at Wood's Bluff. Descriptions of the new 
species and a diagram showing, from Dr. Smith's notes, tlie relations of 
the Wood's BlufT strata to the Buhrstone, were published by Prof. 
Heilprin in 1880 and 1881. 
These papers of Prof. Heilprin, and his Tertiary Geology, contain all 
that was published upon .Vlabama Tertiary from the time of Prof. 
Tuomey up to the publication of tlie present Bulletin, except the 
papers called forth by the curious articles of Otto Meyer, in which the 
attempt was made to throw doubt upon the work of other geologists in 
this field, and to obscure what has long been perfectly well established 
in regard to the stratigraphy of parts of the southern Tertiary. 
The work now under consideration gives the following tal)le of the 
Tertiary and Cretaceous strata of Alabama, with the thicknrss of each:
