The Jennings is exposed throughout the center of the Oakland anti- 

 cline. Most of the exposures, however, are of such a character that it is 

 impossible to make satisfactory stratigraphic measurements of them so 

 that while aboniiding in fossils, the stratigraphy of this part of the Jen- 

 nings is but poorly known.
