Coal and Lignite. 



Coal and lignite, while they occur in New York, can never be 

 found in commercial quantities. The coal measures of Penn- 

 sylvania, are not found north of the boundary line between Penn- 

 sylvania 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 ©oal in New 

 York, but year after year persons 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.

 qua, Erie, Livingston and Seneca counties.
