 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 men appear in the field who seem 

 anxious to pay for their own experience. It can not be too 

 strongly urged upon the attention of the people of the state that 

 it is absolutely useless to seek for coal in New York. 



Coal. Woodstock, Ulster county, thin vein in the Catskill, 

 worked out; in seams interstratified with shale, in Chautauqua, 

 Erie, Livingston and Seneca counties. 



Lignite, brown coal. Near Rossville, Staten Island, thin seam 

 in clay; also in Suffolk county in clays.
