The map is on a scale of ten miles to an inch, the base being com- 
piled from the records of the United States Land Office, and free use 
having been made of the atlas sheets of the United States Geological 
Survey. As shown by the map many of the formations from the pre- 
Cambrian crystallines to the Pleistocene alluvial deposits are found in 
the state. There are the Chilhowee sandstones and the Knox shales 
and sandstones of the Cambrian, three members of the Silurian, one cf 
the Devonian, the sub-Carboniferous and the Coal Measures, four sub- 
divisions of the Cretaceous, four of the Eocene, the Lower and Upper 
Miocene, the Pliocene (Lafayette) and the Pleistocene. 
The map is accompanied by an explanatory chart which is very 
valuable in presenting in a concise and tabulated form the important 
facts concerning each of these formations. In the first column are 
given the names, synonyms, classification and common fossils of each 
of the formations represented on the map. Another column gives the 
thickness, the lithological and topographical characters, the area and 
the distribution. In a third column are placed the useful products 
found in each formation. The respective soils, characteristic timber 
growth and agricultural features are briefly given, and also references 
to the reports in which the ‘formations are more fully described. Some 
such scheme as this, modified as the exigencies of the case might 
require, would add greatly to the value of all general geological maps.

Some Coal Measure Sections near Peytona, West Virginia (with two 
large maps). By Benjamin SmirH Lyman. (Proceedings 
American Philosophical Society, Vol. XX XIII., November 2, 
1894, pp. 282-3009.) 
This paper contains the results of two preliminary surveys made in 
1872, near Peytona, Boone county, West Virginia. The tracts covered 
by these surveys lie, the one twenty-two miles south of Charlestown, the
