Iron Ore. 
Magnetic oxide of iron ore abounds in the mountain region of Rock- 
land and Orange counties. Most of the localities of this ore are on 
three or four lines which extend across these counties from northeast to 
southwest. Sometimes the lines are not continuous, but are dislocated 
by lateral heaves. Their continuity has not been traced throughout, and 
much time and minute observation would be necessary for a perfect de- 
velopment of these veins. 
One of these veins ranges along the northwest faces of the Highlands, 
and the mines on Butter hill, Deer hill, and probably those of the Clove 
mine, O'Neil mine, and Forshee mine may be on this vein. 
The other ranges from the Forest or Dean mine NNE to Kronkite's 
mine, Meek's mine, and the ore bed near West-Point. The ore beds 
on Constitution Island are believed to be a continuation of this vein. 
The same vein is supposed to range from the Forest of Dean mine 
southwestwardly by the Greenwood mine, or else the Hassenclever 
mine, Patterson mine, Mountain mine. Long mine, Crossway mine, 
Sterling mine, and mine to the New- Jersey line. 
Another range of ore seems to extend from the north side of the 
Crow's Nest, where a mine has been opened by Round pond and so on 
towards New-Jersey. 
Another still probably ranges from Fort Montgomery by Queens- 
bury mine, and Rich mine, to New-Jersey. 
Local Details. 
A bed of magnetic oxide of iron occurs about one or two hundred 
yards east of the reservoir at West- Point. Its quantity is not known, 
as no explorations have been made. The indications there are as pro- 
mising as at many productive mines. The ore is associated with horn= 
blende. It has been traced at short intervals for some distance in a 
southerly direction towards Meek's mine on the west part of Bear hill, 
southwest of Buttermilk falls. 
At Meelc's mine the ore is titaniferous. 
Kronkite^s mine on the farm of Richard Kronkite, Esq. is about half 
or three-fourths of a mile southeast of his house, and four and a half 
miles SSW of West-Point. There are two veins of ore separated by a 
sheet of rock. Mr. K. has traced it 50 to 80 rods to the NNE. 800
