MINERALOGY 



Mr H. P. Whitlock, assistant in mineralogy, began work Jan. 

 1, 1901. 



In this division work has progressed along several different 

 lines. 



1 A card index of the mineral localities of New York State 

 has been compiled, and at present consists of 1421 cards ar- 

 ranged as follows: 



a A locality card is placed at the head of each species, on 

 which are listed the localities at which the species occurs. This 

 serves as a means of quick reference and is supplemented by, 



b A descriptive card for each occurrence, giving details of 

 exact locality; peculiarities of crystal form, structure and color; 

 geologic and mineralogic association. 



This index has been compiled with considerable care from a 

 number of sources and has been enlarged by study of the collec- 

 tions of the Egleston Mineralogical Museum of Columbia Uni- 

 versity and that of the American Museum of Natural History. 

 Special care has been taken to locate references to old deposits 

 with respect to modern maps, and to this end some research
