MINERAL RESOURCES OF THE STATE OF NEW YORK 83 



from the Wevertowii quarry in the last few years by the Warren 

 Cotinty Garnet Mills. 



The Crehore mine is the only other property in this section that 

 has supplied any considerable production in recent years. It lies in 

 the same district with the preceding occurrences but is in Essex 

 cotmty just north of the coimt}^ line and about 5 miles northwest 

 of North River on the Indian Lake road. The garnet is found in 

 a band of hornblende gneiss which outcrops on the shoulder of Casey 

 mountain just north of the highway. The exposure measures 40 

 feet or so in width and the band is said to be traceable for about 

 2000 feet. The garnet crystals measure 6 to 8 inches in maximum 

 diameter. The matrix contains a large proportion of black horn- 

 blende and is somewhat like the Gore mountain garnet rock. The 

 American Glue Co. has worked the mine at intervals for supplying 

 some of its own requirements; up to the present time the product 

 has been obtained by hand picking and cobbing. The company 

 has plans under consideration for a mill to separate the garnet 

 mechanically and with its facihties will be able to operate the prop- 

 erty on a larger scale. 



Another locality for garnet in this section is on Oven mountain, 

 4 miles south of North Creek, where some garnet was taken out 

 20 years or m.ore ago. The occurrence is reported by W. J. Miller 

 (see references at end of article) to resemble that on Gore mountain, 

 consisting of a long narrow band of dark hornblende rock inclosed 

 by syenitic gneiss. There has been a little work done on the Rexford 

 property, about i mile south of North Creek. 



Outside of the North Creek district the production of garnet 

 has not been important although a nimiber of occurrences have 

 received more or less attention. The American Garnet Co. for a 

 few years operated a deposit in northern Essex county, a few miles 

 south of Keeseville on the Clinton county border. The garnet 

 occurs in the form of rock in places almost free of admixture but 

 usually containing a proportion of green p3rroxene and belongs to 

 the massive variety. It is inclosed v^rithin anorthosite, representing 

 a band of Greenville limestone caught up and metamorphosed during 

 the intrusion of the igneous rock. The product was sorted by hand 

 and marketed in lump form, most of it being shipped abroad. The 

 mining operations were suspended with the outbreak of the war. 



About 3 miles north of Gouvemeur, St Lawrence county, a body 

 of garnet rock occurs that was worked for a time by Amasa Corbin. 

 The garnet is in small grains not more than one-fourth of an inch 

 in diameter as a rule, plentifully sprinkled through a green quartz-
