The region discussed in the following paper embraces portions of the Rome and Fort Payne atlas sheets of the United States Geological Survey in Georgia and Alabama. The outlines of its geology have already been presented to this Society in a paper read at the Washington meeting in 1890. While the main features of its structure were known at that time the details had not yet been worked out. Further study of this region during the past summer has cleared up much of the obscurity heretofore surrounding its geologic history, and it is believed the results obtained are of sufficient importance to warrant bringing the subject before the Society again; also recent work by Mr Walcott on the paleontology of the region has made possible certain stratigraphic correlations of considerable interest.
The accompanying map shows the areal distribution of the formations within the region, and . . .
