for cutting, and returned to be sold at Denver and Colorado 

 Springs, Colo., at Hot Springs, Ark., and other interior resorts, 

 as jewelry to tourists. The annual sales amount to about

Large crystals, up to 4 or 5 inches in diameter, have been 

 collected at Brandy creek, in Lemhi county, Idaho. They 

 have been found, too, at Three Mile gulch, near Helena, Mont., 

 and a gigantic crystal, nearly two feet long and weighing 93i 

 pounds, was found in 1900, on Clear creek, Jefferson county, 

 Mont., by Mr. E. P. Chisolm. Crystals have also been reported 

 at points in South Dakota. A considerable quantity occurs in 

 connection with the colored tourmalines in Southern Califor- 

 nia, both at the San Jacinto mine in Riverside county and those 

 at Mesa Grande in San Diego county. 



In the east very fine smoky quartz has been found in 

 Maine and in North Carolina, as well as at some other points. 

 The specimens from Maine are particularl}'' beautiful. Cr^^s- 

 tals of 40 pounds in weight were reported in 1896, by Mr. R. M. 

 Chatham, from a locality near Elkin, in Surry county, N. C, 

 and it was already well known in the neighboring counties 

 of Alexander, Burke, and Iredell. 



The delicate pink variety of quartz known as rose quartz 

 has long been obtained at several points in New England, 

 especially at Albany, Stow, and Paris, in Maine ; at Southbury , 

 in Connecticut ; also at Bedford, in Westchester county, N. Y. 

 Though a beautiful material, it had been little used in the arts 

 or as a gem until quite recently, w^hen it was tried with some 

 success. In general, and particularly in the case of the speci- 

 mens from the localities in Maine, the tint varies greatly from 

 an almost colorless variety, sometimes opalescent, to pale 

 pink, salmon, and deep rose. When cut into double ca- 

 bochons, or balls, it sometimes shows the asteria effect, like 

 a star sapphire. Very fine, rich colored pieces, partly opal- 

 escent and in size up to 4 or 5 inches in diameter, have been 

 obtained at Round mountain, near Albany, Me. Rose quartz 

 occurs also at Acworth, N. H., in the celebrated beryl locality, 

 and a large block of this material, some 5 feet square by half
