192 NEW YORK STATE MUSEUM 



Edwards, St Lawrence co. Muscovite in plates and large pris- 

 matic crystals occurs at Edwards. 



Elsewhere in St Lawrence county, muscovite and phlogopite 

 are found in ismall amounts and, for the most part, in dark 

 colored varieties. 



7 Coal and lignite. Coal and lignite, while they occur in New 

 York, can never be found in commercial quantities. The coal 

 measures of Pennsylvania are not found north of the boundary 

 line between Pennsylvania and New York, and what coal has 

 been discovered in the latter state is in older formations, which 

 do not contain this valuable mineral in commercial quantities. 

 Many thousands of dollars have been spent in fruitless efforts to 

 obtain coal in New York, but year after year persons who seem 

 anxious to pay for their own experience appear in the field. It 

 can not be to'o strongly urged on the attention of the people of 

 the State that it is absolutely useless. to seek for coal in New 

 York. 



Woodstock, Ulster co. Coal was formerly found in a thin vein 

 in the Catskills. The vein is worked out. 



Coal also occurs in seams inter stratified with shales in Chau- 

 tauqua, Erie, Livingston and Seneca counties. 



Rossville, Richmond co. A thin seam of lignite, or brown coal, 

 occurs in clay. 



Lignite is also found sparingly in the clays of Suffolk county.
