RARE QUARTZ TWINS! 



Just arrived from Japan ! 30 choice contact twins with 

 twinning plane <f (1122). similar to figure 11 on page 184 

 of Dana's System, but without the modifications, and with 

 crystals quite flat (like figure 12), crystals about three- 

 quarters of an inch in size. The excessive rarity of con- 

 tact twins of quartz will make this little lot sell very 

 rapidly at 50c. to $2 00. 



RARE ALEXANDER COUNTY, N. C, 

 aUARTZ. 



From our collector, who has already spent over two 

 months in North Carolina, visiting all of the most desir- 

 able localities for us, we have received by far the finest lot we ever had of the 

 famous Alexander County Quartz crystals. The crystals are mostly of the type 

 shown in figure 17 on page 185 of Dana's System, though they often are much 

 more complex, and at least five or six of them should be secured to show the 

 different forms. Nearly all of them are perfectly clear and flawless, delicate, 

 smoky crystals, with very brilliant faces; they range from three-quarter inch to 

 3 inches in length with diameter about one-third the length. Prices 10c. to S2.00. 

 A suite of five best quality crystals (averaging about 1 and 1J inches in length) 

 postpaid for SI. 30. 



WONDERFUL FINDS OF AMETHYST. 



Our N. C. collector has been especially alert for fine Amethysts, and has visited 

 numerous localities, has worked several and we have finally purchased outright 

 the best locality we have ever heard of, and have already taken out Thousands 

 of Beautiful Specimens, both single crystals and groups. We believe this is 

 the most important find of Amethyst specimens ever made. The color is rich, the 

 crystals well formed and of large sizes, every element is present which contributes 

 to makes a specimen desirable, including the fact that none have previously been 

 in the market from this new locality in Iredell County, N. C. "We also have a 

 large lot of fine specimens from Macon County, N. C, and from Eabun County, 

 Georgia, 10c. to 85.00. Specimens at 50c. to 82.50 will be acceptable additions to 

 the very best collections. 



OTHER NORTH CAROLINA MINERALS. 



The loose terminated crystals of Green Cyanite secured by our collector con- 

 tinue to please scientific collectors. But few fine crystals, consequently, remain; 

 50c. to 82.00. 



A few good, large size Columbite crystals are still in stock at 50c. to 82.50. 



The Iredell County Zircons, of winch a new lot has just arrived, increase 

 in popularity as their merits become known — large size, rare form, bright faces, 

 low prices: 5c. to 50c. 



RARE CONNECTICUT MINERALS. 



An exchange with a near-by University brings us some good and rare minerals ; 

 several loose crystals of Monazite, several small but good Uraninite 

 Crystals, a little lot of Columbite Crystals, 22 terminated Beryls, several 

 richly colored Iolite specimens, etc. 



RARE COLORADO MINERALS. 



An exceptionally interesting little shipment' from a Colorado collector enables us 



to offer good, small specimens of Crystallized Calaverite and Gold Pseudo- 

 morphs after Calaverite ; fine, large specimens of Sylvanite, also a few 



specimens of Altaite and the exceedingly rare Melonite ; we are also able to 

 furnish good specimens of Johannite and a lot of good and large, loose crystals 

 of Selenite from a new Colorado locality. 



• Many other recent additions ought to be mentioned, but space forbids. Quite a 

 number of them are noted in our Fall Bulletin recently published, mailed free on 

 application.
