STATISTICS OF CLAY PRODUCTION 509 



APPENDIX A. 



STATISTICS OF PRODUCTION. 



New Jersey ranks third in the total value of its clay products, 

 Ohio* being first and Pennsylvania second. So steadily and rap- 

 idly has the output increased that since 1897 it has nearly doubled. 



The value from 1895 to 1902 is given below, the figures being 

 taken from the reports on Mineral Resources issued by the United 

 States Geological Survey:
