HIGH-GRADE CLAYS OF THE UXITED STATES 



BY H. RIES 



(AT)stract) 



The United States requires a large amount of high-grade clay for use in 

 ceramic and other industries. Much of this was formerly imported from Eu- 

 rope, but the foreign sources of supply having been partly shut off by the war, 

 it has become necessary to draw on domestic supplies as far as possible. 



It has been found that domestic clays can replace imported ones to a larger 

 extent than hitherto practiced, and there are probably abundant reserves in 

 the United States. 



White residual clays are developed from : 1, pegmatite veins, in North Caro- 

 lina ; 2, Cambrian schists, in southeastern Pennsylvania ; 3, Cambrian quartz- 

 ites, in central Pennsylvania ; 4, Cambrian shales, in Virginia : 5, Cambrian 

 limestones, in Missouri, and, 6, Oriskany shales and limestones, in Pennsyl- 

 vania. These supply the china, paper, and paint industries. 



1 Since the meeting the Secretary has received, under date of .January 6. 1919. the 

 following communication : 



"On behalf of the Auditing Committee of the Geological Society of America. I exam- 

 ined on January 4, 1919, the securities of the Society in the safe-deposit box at the 

 Baltimore Trust Company and found them to be as listed in the printed report of the 

 Treasurer (proper coupons attached).
