and 3.7 respectively. Mr Hooper has not made public the de- 

 tails of his separation process, but, by its means, the present 

 plant is capable of crushing and separating 150 tons of ore per 

 day (1903). 



The entire output of the mines of this company is sold to 

 Herman Behr & Co., of Xew York city, Boston and Chicago, who 

 have extensive plants for the preparation from the raw material 

 of the various forms of garnet paper, etc. 



H. H. Barton & Sons Co., of Philadelphia Pa., woT'k mines 

 on Gore mountain in close proximity to the mines of the North 

 River Garnet Co. Here the garnet is found in pockets averaging 

 from 5 to 10 inches in diameter, occurring near the summit of 

 the mountain in a decomposed hornblende rock. The mines are 

 all open cuts, workable material being found almost on the sur- 

 face. 



There is at present no plant connected with these mines. The 

 product is all hand-picked. Further development of the property 

 will probably render the erection of a mechanical separation plant 

 a necessity. 



According to figures furnished by H. H. Barton & Sons Co. the 

 Gore mountain mines produced during 1902 a;bout 1000 net tons.
