Minerals and Gems 63 



in ash gray crystals which are almost diagrammatic in the per- 

 fection of their development. Remarkably large and perfect 

 examples of scheelite, from a new locality in Mohave County, 

 Arizona, have been added to the collection. These are repre- 

 sented by a single crystal nearly two inches in diameter, and 

 a group showing scheelite associated with black tourmaline 

 which is both striking and attractive. Equally attractive by 

 reason of its brilliant color contrast is the uranopilite on 

 chalcopyrite from Montrose County, Colorado, in bunched in- 

 crustations of a fluorescent yellowish green. Among the newly 

 discovered minerals represented in this year's accessions, are 

 spencerite, a zinc phosphate from the Hudson Bay Mine at 

 Salmo, British Columbia; crestmoreite, a new hydrous silicate 

 from Crestmore, Riverside County, California, and temiska- 

 mite, a new (1914) nickel arsenide, represented by specimens 

 from two Canadian localities. A striking example of mineral 

 association is represented by a large moss-like stalactitic mass 

 of psilomelane, enclosing crystals of native copper and dotted 

 with malachite, from Warren, Arizona, the gift of Mr. L. D. 

 Ricketts. The more local mineral occurrences to be found 

 among the year's accessions include a large and very fine crystal 

 of amazonite from Valhalla, Westchester County, the gift of 

 Mr. James G. Manchester. 



The Morgan Gem Collection has been enriched, through the 

 gift of Mr. J. P. Morgan, by the addition of three magnificent 

 cut opal pieces of rich color and fire from Humboldt County, 

 Nevada, also two large facetted tourmaline gems, wine red in 

 color, from Brazil, and a large tourmaline roughly shaped in 

 the Chinese manner from San Diego County, California. 



The use of minerals for carved ornaments is represented by 

 a series of beautiful Chinese carvings in agmatolite which were 

 exhibited at the Centennial Exposition in 1876. These include 

 a large stand supporting figures of the Nine Worthies of China, 

 two seated figures of Chinese Sages, and two tall flower vases 

 ornamented with vine and foliage forms. They were presented 

 by Messrs. Albert G. and Jerome J. Hanauer.
