II. — THE GEOGRAPHIC SERIES OF ORES AND USEFUL MINERAL SUB- 

 STANCES. 



In this exhibit, which is confined to the limits of the United States 

 with a possibility of extension so as to include Canada and Mexico, the 

 materials are arranged on a geographic basis, i. e., by States. The idea 

 in mind is to give the publican opportunity to learn almost at a glance 

 the character of the mineral product of any particular State or region. 

 The exhibit is confined to the wall cases extending entirely around the 

 South West Court. 



Entering this court from the West South Eange the series begins 

 immediately upon the left. 



The following statement is given relative to the arrangement of this 

 collection and its present condition.
