VOLCANIC BOMBS FBOM IDAHO 



WE have just purchased a most remarkable collection of volcanic bombs 

 and take pleasure in offering them at most reasonable prices. 



These bombs are of black color, dense to vesicular in texture, and often 

 show large blow holes. The above illustration (one-third less than natural 

 size) will give an idea of a few of the many types. Each of these is a 

 40-cent specimen. 



Sizes range from a few as small as one inch to a few as large as six 

 inches, the greater number averaging two to three inches. 



Prices range from 15 cents to $1.50, postpaid. A carefully selected suite 

 of medium size specimens (2 to 3 inches) will be sent postpaid for $2.00. 



We believe these are the neatest and most attractive volcanic bombs ever 

 on the market. 



PELE'S HAIR 



Another remarkable volcanic product from the great volcano of Kilauea, 

 Hawaii. We have been so fortunate as to obtain a little lot of the very best 

 quality of this truly wonderful material. Except for a very few small globules 

 of obsidian scattered through it, its likeness to human hair is so striking as 

 to deceive almost anyone. Large glass-covered boxes filled with Pele's Hair, 

 60 cents each, postpaid. 



ROCKS 



We wish to call attention again to our new Price List of Rocks (No. 148), 

 enumerating several hundred typical American and ^nany foreign rocks 

 which we regularly carry in stock, and giving our very low price both on 

 trimmed specimens and on chips for students. 



Numerous additions to our stock have been made even since the publica- 

 tion of this list. There are but few really important rocks not now 

 abundantly represented in our stock.
