THE MINING AND QUARRY INDUSTRY 1915 29 



only twice in recent years has it exceeded 5000 tons. Prices vary 

 with the quality of the product, but the best crystal garnet which 

 comes from the North River district holds steadily at $35 a ton. 



The active producers in the Adirondack region last season 

 included the North River Garnet Co. with mines on Thirteenth 

 Lake, H. H. Barton & Son Co., operating on Gore mountain, and 

 Warren County Garnet Mills at Riparius, all in Warren county. 

 The property on Mount Bigelow, near Keeseville, in northern Essex 

 county, recently worked by the American Garnet Company, was 

 idle throughout the year. The resources of garnet in the Adiron- 

 dack deposits are large and capable of yielding a much greater 

 quantity than is now produced ; it is no lack of capital or enterprise 

 on the part of the mining companies that holds the production down 

 to the present proportions, but the market is strictly limited and 

 shows little tendency to growth. 



Outside of the Adirondacks, garnet occurs in association with 

 metamorphic rocks along the Appalachians from the New England 

 states south to North Carolina and Alabama. The Highlands of 

 southeastern New York belong to this mountain range, and in the 

 vicinity of Peekskill, Westchester county, there are garnet deposits 

 which have been worked in a small way. New Hampshire, Pennsyl- 

 vania and North Carolina have yielded more or less of the mineral 

 in recent years, but nowhere except in the Adirondacks has the 

 mining industry attained any great importance. 



The use of garnet as an abrasive has not made much headway in 

 foreign countries. Spain is the only country of Europe which 

 produces it in quantity and the output is sent to this country for 

 manufacture. Spanish garnet is obtained from alluvial deposits 

 which are found in the province of Almeria ; it is of rather fine 

 grain and only a partial substitute for the American product. The 

 imports into the United States in 191 5 were 1343 tons, with a 

 declared value of $24,472; in 1914 they were reported as 1244 tons 

 with a value of $20,277. There is no duty on the mineral and 

 owing to the character of the Spanish deposits the foreign garnet 

 can be shipped into this country at a cost well below that attainable 

 by the domestic producers. 



GRAPHITE 



A production of flake or crystalline graphite was reported for last 



year as usual by the American mine at Graphite, Warren county. 



The output of this mine has long been the chief factor in the local 



industry, as in fact also it has represented a large share of the
