194 THE COASTAL PLAIN" FORMATIONS OF CECIL COUNTY 



" Pensauken " is on account of a thin bed of gravel carrying Triassic 

 shale cobbles and having the general aspect of " Pensauken." Pro- 

 fessor Salisbury on this ground concluded at first that the Fish House 

 clays were " post-Pensauken " but in the subsequent year assigned 

 them to the " Pensauken " formation. 1 Mr. Woolman on account of 

 the presence of Newark shale above the clay regarded it as lying in 

 the body of the so-called Pensauken formation. 



The author regards the Pish House clays as identical in age and 

 manner of formation with similar deposits further south, and conse- 

 quently refers them to the Talbot formation.
