TALC 



The talc mines in St La:wrence county were operated last year 

 on about the usual scale. During the last decade the production 

 has averaged about 65,000 tons a year and has not varied from 

 that amoimt by more than a few thousand tons. In 1907 the total 

 fell off to 59,000 tons, due to the destruction by fire of one of the 

 large mills, but this shortage was counterbalanced in 1908 by an 

 output of 70,739 tons. In 1909 the production may be placed at 

 about 65,000 tons. The value of the product was approximately 

 $617,500 as compared with $697,390 in 1908. 



A general description of the St Lawrence county deposits and of 

 their industrial development was given in the issue of this report 

 for 1908. Following the recent consolidation of mining interests 

 by which the properties formerly operated by the L^nited vStates 

 Talc Coi. and the LTriion Talc Co. came under the control of the 

 International Pulp Co., no further changes of note have occurred. 

 The latter company has been for some time the largest producer in 

 the region and now occupies a dominant position in the production 

 and sale of ground talc in this country. 



The Ontario Talc Co. was the only independent prodncer in the 

 district last year. The Uniform Fibre Talc Co. of New York, has a 

 mill under construction at Talcville and i,s expected to begin opera- 

 tions during the current season. Its mining property is on Winter- 

 green hill, just west of Talcville.
