Hematite is also found along the whole western side of Bellvale 
mountain, and in places along the Warwick valley, to the New-Jersey 
line. 
Thus it appears, that in Orange, one great iron region extends from 
the Hudson river on the east side of Butter hill quite across to Rock- 
land county. 
Another on the west side of Butter hill follows the valley across 
Cornwall, east of Skunemunk mountain, through Monroe, and by way 
of Sterling into New- Jersey, and far across that State. 
The amount of ore in these deposits, which is of easy access, and 
has the most perfect facilities for cheap mining, is perfectly inexhausti- 
ble. 
The amount of iron to be made in the county in all time to come, 
can only be limited by the supply of coal necessary for the reduction of 
the ores.
