WE KNOW HOW 



Our selections of mineralogical and geological specimens are 

 the result of years of experience. 



When our collections are made up great care is exercised in 

 order that they may contain only the very best and most typical 

 material which our extensive resources enable us to furnish. 



"The specimens I received from your firm awhile ago are very 

 fine, the best I have seen for student work," says a professor of 

 geology in an eastern college. 



Such gratifying testimonials lead us to believe that you, too, 

 are in need of material which we can supply to your satisfaction if 

 you will but request it. 



Let us know your wants in mineralogic and geologic lines. 



Collections of minerals, rocks and ores, ready for immediate 

 shipment. Orders promptly and satisfactorily filled. 



We are now exclusive agents in the U. S. and Canada for the 

 crystallographic models and supplies manufactured by Dr. F. 

 Krantz in Bonn.
