The statistics show that the production has continued fairly 

 steady from year to year, but does not manifest any marked growth. 

 The value of the product has remained at about the same level 

 also, the prices ranging around $30 and $35 a ton, depending on 

 the quality. The mill product when it is clean crystal garnet of 

 good color commands the highest prices. 



The garnet is practically all sold in this country. The domestic 

 manufacturers also import some garnet from Spain where it is 

 obtained by the washing of river sands. This garnet is of 'fine size 

 and hence finds a rather limited application. It is said to cost 

 about $15 a ton laid down at the Spanish seaboard, which is much 

 less than the cost of mining the Adirondack mineral. 



The imports for the year 19 14, as given by the collectors of 

 customs at the ports of New York and Boston, were 1244 short 

 tons with a declared value of $20,277. In 1913 they amounted to 

 547 short tons with a value of $8078. 



GRAPHITE 



The usual output of crystalline graphite was made last year in 

 the Adirondack region, and as heretofore the main source of supply 

 was the American mine at Graphite, Warren county, which has had 

 a long record as a producer. The mine affords a very light, flaky 

 graphite that commands a special market. The graphite occurs in 

 disseminated condition through the body of a hard quartzite, re- 

 quiring special methods for its extraction and preparation, which 

 have been perfected by the owners of the mine, the Joseph Dixon 

 Crucible Co. The rock is crushed and the graphite extracted in a 

 mill situated at the mine, and the crude product is then refined and 

 finished at a second plant in Ticonderoga.
