40 NEW YORK STATE MUSEUM f 



from Newcomb have also proved of interest as showing several 

 rare crystal forms. 



A case containing a few examples of the large and unique calcite ^ 

 crystals from Sterlingbush has been installed in the corridor of the 

 fourth floor of the Capitol where the fine pink and purple colors of 

 these specimens show to excellent effect. 



The packing for storage of the large collection of New York 

 minerals was completed and a system of labeling for the boxes has 

 been devised by which newly collected material can be readily 

 sorted into its place when the entire collection is reassembled. 



A collection illustrating the recent work of the museum in miner- 

 alogy was exhibited at the last annual reception of the New York 

 Academy of Science at the American Museum of Natural History 

 in December. 



The mineral collections have been enriched through the gift of 

 Mrs J. V. L. Pruyn of a collection illustrating the minerals from the 

 vicinity of Mount Vesuvius, and by the gift of Mr H. H. Hind- 

 shajM of a large collection of minerals from Lyon Mountain, Clin- 

 ton co., N. Y., which latter amply supplements the material previ- 

 ously acquired by the museum from this interesting locality. A 

 beautiful series of minerals from foreign localities was obtained 

 from Dr F. Krantz of Bonn. 



The field work of this section has resulted in the collection of a 

 mmiber of handsome specimens from the graphite mines in the 

 vicinity of Crown Point and Ticonderoga, Essex co., of a series 

 of over 50 specimens of tremolite from a new locality near Gouver- 

 neur, St Lawrence co., and of a large number of specimens of 

 calcite for exhibition and study from the limestone quarries at 

 Smith's Basin, Alsen and West Camp. 



An important addition to the series of gem minerals from New 

 York, comprises 26 crystals of diopside from the well known locality 

 at DeKalb, St Lawrence co. These average 15 millimeters in 

 diameter, the largest measuring 35 millimeters across the basal sec- 

 tion. They are, for the most part, transparent and of a fine emerald 

 green color. They were obtained by the Assistant State Geologist 

 from Mr Calvin Mitchell of DeKalb Junction.
