PYRITE 



There was a small output of pyrlte from the St Lawrence county 

 mines during the past year. The quantity reported was 11,798 long 

 tons valued at $35,550, as compared with 10,100 long tons valued 

 at $40,465 in 1905. The production was rather incidental to the 

 preliminary work of development, than to regular mining. 



The deposits in St Lawrence county have been under exploitation 

 for several years, yet mining operations, hitherto, have had a desul- 

 tory character without any stable or permanent basis. The main 

 difficulty which seems to have prevented a successful issue of the 

 various undertakings started in this field has been the lack of ade- 

 quate capital to open the mines and equip them for large scale 

 operations. The problem involved is very similar to that of mag- 

 netite mining in the Adirondacks. 



The St Lawrence Pyrite Co., who took over the Stella mine at 

 Hermon, has inaugurated the most extensive, as well as, perhaps, 

 the most promising developments that have yet been undertaken. 

 The company recently completed a 500 ton mill on the property 

 and has been engaged during the year in opening the mines to 

 supply an adequate output of ore. A railroad from the village of 

 Hermon to Dekalb Junction has been built by the company and will 

 enable it to ship the ore by car direct from the mill. There are five 

 ore deposits on the property, of which two are being worked. 



The Cole mine near Gouverneur, formerly owned by the Adiron- 

 dack Pyrite Co., has been taken over by the American Pyrites Co. 

 The mine has shipped in the past a considerable quantity of lump 

 ore. It is equipped with a mill. 



QUARTZ 



Westchester county has contributed a small output of quartz each 

 year. The mineral is obtained from veins where it occurs nearly 

 pure and also from pegmatite dikes in which it is mixed with feld- 

 spar. The product is used in part for pottery, being shipped to 

 manufacturers of these articles at Trenton, N. J. ; it is also employed 

 in making wood filler and silicate paint. The Bridgeport Wood 

 Finishing Co. of New Milford, Ct., and P. H. Kinkel of Bed- 

 ford, N. Y., were the only producers during the past year.
