MINERALS-NEW ARRIVALS. 



Finely crystallized Mazapilite, Hanksite, Colemanite, Descloizlte, Thenardite in crosses, 

 Red and yellow Wulfenite, Azurite, and Malachite pseudomorph after AzuHte, 

 Vanadinite, Opals polished and rough, silver minerals. Over 130 boxes of choice 

 minerals from Mexico, California, Arizona, and the southwest have been purchased or 

 collected at the localities by Prof. Foote in a trip of over four months. 



Hanksite, Colemanite, Etc. 



A week's visit at Borax Lake (the best locality) secured the finest crystals of 

 Hanksite ever seen. 



A month before our visit an 8-inch well had been drilled to a depth of over 100 

 feet for the purpose of exploring the immense alkaline deposit. At the depth of 35 

 feet a small cavity was struck, from which were pumped through the drill hole the 

 finest crystals ever seen. In these the pyramidal planes were much more developed 

 than in the crystals originally described. There were only a few of these that were 

 perfect, the most of them being broken by the drill. All of these, except a very 

 few given to one person before I arrived, I secured. 



The groups similar to Aragonite, are more common. Groups, 25 cents to $5.00. 

 Extra large museum groups $5.00 to $10.00. 



As all these specimens were secured by me at the locality, they were oiled by me 

 on the spot, and do not present the rounded or worn appearance usually shown. 



The failure of the principal firm mining boric acid minerals for several millions of 

 dollars, and their offer of 40 cents on the dollar to their creditors, indicates that the 

 borax deposits will be worked far less in the future than in the past. 



For this reason Colemanite, Thenardite, and other alkaline minerals, will probably 

 be more scarce in the future than in the past. The best Colemanite we got came 

 from a collection made several years ago. Cleavages, price 5 cents to 25 cents; 

 crystals 10 cents to 50 cents ; fine groups of crystals 50 cents to $10.00. Thenardite in 

 fine crossed crystals, 5 cents to $1.00. We have also Borax, from San Bernardino Co., 

 Cal., at from 10 cents to $1.50. Some things are now being examined. 



Arizona Minerals. 



Descloizlte from Pima Co. .-—The largest crystallized specimen of tLte rare mineral 

 that has ever been seen, weighs 2% lbs., measures 9% inches in length and seven in 

 diameter, $100.00 ; smaller well-crystallized specimens, some associated with Vana- 

 dinite crystals, $2.00 to $10.00 ; fragments well crystallized, 10 cents to $1.50. 



Vanadinite doubly terminated crystals, with straw-colored centers and red termi- 

 nations on good pieces of gangue, Pima Co., $1.00 to $5.00; fragments well crystal- 

 lized, 5 cents to 75 cents. 



Brown barrel-shaped crystals, from 25 cents to 5.00. 



Wulfenite Bed.— Another hard trip to the Red Cloud mine enabled us to secure 

 some specimens that the superintendent had been saving for us for over a year. 

 We were there in July and under date of September 27th. He writes us : " That he 

 is sorry to say they have found no more Wulfenites." 



As the district is now almost entirely abandoned, and no more good specimens 

 are now found at the mine, we were very glad to secure these; having sold all taken 

 to Europe. Large specimen groups, $1.00 to $25.00 ; fragments and crystals, 5 cents 

 to $1.50. 



In New Mexico we were very fortunate in striking a pocket of brilliant yellow 

 Wulfenite equal to the best ever found at Eureka, Nevada. It is associated with 

 flos ferri. The thin and delicate plates are very beautiful. Specimens, $2.00 to 

 $10.00 ; fragments, brilliant, 10 cents to $1.50. 



From the Copper Queen mine and from Morenci we have obtained the finest 

 Azurites and Malachite pseudomorph after Azurite ever seen. 



Malachite fibrous in beautiful surfaces and tufts, 5 cents to $5.00 ; same penetrat- 

 ing clear calcite, 25 cents to $10.00 ; Malachite polished, 50 cents to $3.00 ; Malachite 

 and Azurite banded in a charming manner, 75 cents to $5.00. 



Chrysocolla, with a very glossy, lustrous fracture, the finest ever seen, 10 cents to 

 $5.00. 



Cuprite, brilliant, 5 cents to $5.00. 



Mexican Minerals. 



These are the result of the purchase of six entire collections of mining engineers 

 and experienced collectors, and the choice of all the specimens in the private col- 

 lection of the Professor of Mineralogy in the Mining College of Guanajuato. These 

 purchases aggregated several thousands of dollars. 



Opals. We have brought back from Mexico this time the finest lot of these we 

 have ever seen for sale. We have them of all kinds, precious or noble, fire, harlequin, 

 milky, opal agate, opal with inclosures, hyalite, etc., etc., cut and in the rough, from 5 

 cents to $100. 



Obsidian. Red and Black, from 5 cents to $1.00. 



The Twin Calcites that we got from Guanajuato are more interesting in form than 

 any we ever got before. 



Apophyllite, 12^£ x 10 inches, very fine surface entirely covered with large crystals, 

 $50.00. Rose colored Apophyllite, $3.50 to $20.00. 



Valencianite, from the old Valenciana mine, in fine museum. 



Cassiterite, both tinstone and large masses, 25 cents to $10.00. 



Mexican Onyx beautifully banded, 25 cents to $2.50. 



We again revisited the celebrated Turquois locality in New Mexico, and have 

 some of the finest deep blue pieces we have ever seen, 10 cents to $7.50 each. 



Other minerals have been received in large quantities, but we have only space to 

 mention the very interesting crystals of Magnetite from the Moriah mine, Essex 

 County, N. Y. 



Over 200 boxes of minerals and scientific books received in 1888.
