The talc from the St Lawrence county mines is mainly of fibrous 

 nature and it is this feature which makes it particularly valuable for 

 incorporation in paper stock. I'he foliated variety occurs in some 

 of the deposits but is utilized to a smaller extent ; it is admixed in 

 small amount with the fibrous article or is ground separately for 

 coating of wall papers and other uses. 



Though the district which lies southeast of Gouverneur has at- 

 tracted most attention, the occurrence of talc efeewhere in the Adi- 

 rondack region has long been knoiwn. During 1909 a deposit situ- 

 aited near Natural Bridge, Lewis co., was under development by thie 

 St Lawrence Talc & Asbestos Co, The talc is found there in some^ 

 what similar relations geologically to those in the more northerly 

 district, but it has the character rather of amorphous talc or soap- 

 • stone, resembling the material from the Southern States. The recent 

 operations are reported to have revealed a large quantity of rock 

 of good quality. Natural Bridge is near the southern end of the 

 belt of crystalline limestones and schists which belong to the same 

 series as the limestones and schists in wdiich the fibrous talc deposits 

 are found, the two belts being about 10 miles apart and trending 

 parallel in a northeaist-southwest direction.
