Several shipments of interesting minerals from Montana have lately been 

 received, a number of the most notable being reviewed below. The great 

 mineral wealth of this district is well-known, and to its present activity is 

 due the increasing number of mineral species reported. 



CRYSTALLIZED RHODOCHROSITE. Characteristic rhombohe- 

 drons of a rich pink in aggregates, clean cut and perfect. They lack the 

 translucency of the Colorado find, but in other features closely resemble the 

 material from that state. Crystals vary in size from % to an inch and more 

 across with corresponding thickness. Occasionally, groups are coated with 

 a white drusy quartz making an association both interesting and attractive. 

 Prices 50c. to $2.00. Massive 50c. per lb. 



CRYSTALLIZED ENARGITE. A few neat groups of the rare cop- 

 per sulpharsenate, illustrating habit and modifications. Crystallized metal- 

 lic minerals find quick sale, and it is confidently expected that at our low 

 scale of prices, the best of the lot will be immediately sold. Prices 50c. to. 

 $3.00. Massive ?5c. per lb. 



AMETHYST. Our correspondent spent several months at the Ame- 

 thyst locality, and after much difficulty succeeded in securing what are con- 

 sidered the finest specimens as yet found { The types show parallel growth, 

 interesting capping forms and single doubly terminated crystals. Color is 

 good, generally deepening at the tips. Convenient cabinet sizes — 50c. to 

 $4.00. 



TOURMALINITIC QUARTZ. 



Two shipments of this odd occurrence permit us to describe its varied 

 habits and strange associations. In appearance the crystals are black, due to 

 the fine network of included Tourmaline hairs, which occasionally are widely 

 separated, reminding one of .the more common "fleches d'amour." A pecu- 

 liar "stem" extends beyond the base of some crystals, around which the 

 Quartz seems to have formed. The Tourmaline is often isolated on the 

 "stem," appearing in bristling tufts and masses. The very fact that these 

 specimens differ widely from the usual Quartz forms, makes them attractive 

 to the collector, -but aside from this point they combine such interesting 

 features scientifically, that a steady demand is anticipated. Prices 50c. to 

 $3.50 in 2 and 4 inch sizes. 



COVELLITE, CHALCOCITE and BORNITE in pure massive 

 lumps neatly trimmed to cabinet sizes. 50c. to $1.00 for a typical specimen. 



Trial orders solicited. Approval consignments submitted.
