at very little loss ; not taking into con- 

 sideration, however, the amount of per- 

 sonal pleasure which he has derived 

 from the companionship of his speci- 

 mens nor the touch of refinement which 

 it naturally gives its possessor. 



1 was surprised at the remarkable 

 system which Air. Petereit has adopted 

 in all his departments in order to facili- 

 tate the handling of his daily corres- 

 pondence, also the excellent method of 

 labeling and pricing which is found 

 throughout his entire stock. Here we 

 can select a diamond, ruby or sapphire 

 of any size desired, and have it tested 

 before purchasing. This is a very satis- 

 factory method, as it gives entire confi- 

 dence in anything one buys here. The 

 scientific accuracy of the labels on his 

 mineral specimens is another feature of 

 this establishment, and as each specimen 

 is priced, patrons are not embarrassed 

 by asking the cost of anything they are 

 interested in nor finding it more expen- 

 sive than they can afford to pay. Here 

 both the rich and poor collector can feel 

 satisfied with his selection. 



I learned that Air. Petereit numbers 

 among his patrons most of the important 

 scientific institutions both in this country 

 and abroad ; also a great many of our 

 prominent and wealthy citizens and that 

 he has, on numerous occasions, fur- 

 nished specimens direct to several royal 

 houses in Europe and Asia. 



While glancing through several pa- 

 pers from western cities, I found they 

 included articles descriptive of the excel- 

 lent collections of cut gem-, gem crystals 

 and gem material, which Mr. Petereit 

 has kindly loaned some of the institu- 

 tions. These collections are to illus- 

 trate the new departments which re- 

 cently have been established in main- im- 

 portanl mining colleges, namely the min- 

 ing of gems and gem minerals. I have 

 also recently been informed that the 

 Colorado School of Mines at Golden, 

 Colo., has adopted this branch and, upon 

 their being tillable to procure a collec- 

 tion for this purpose elsewhere, Mr. 

 Petereit furnished them with the loan of 

 what they desired through which act his 

 philanthropic nature is strongly brought 

 to light. 



The inauguration of this department 

 proves the progressiveness of American 

 methods in our institutions of learning, 

 as the U. S. has untold wealth in gems 

 and which has not, as yet, been fully ex- 

 plored, although mining for gems has 

 been conducted in a haphazard way for 

 some years. The remarkable gem 

 stones of North Carolina, Maine, Cali- 

 fornia and Montana give but a slight 

 idea to the Old World the immense pos- 

 sibilities of the Xew. We can hardly 

 glance over a newspaper without finding 

 some announcement of a newly discov- 

 ered deposit. 



But I must come back to the subject 

 of this article and shall try to describe
