at the mica locality, near the Forshee mines, Monroe, at the Two 
ponds, Monroe, and numerous other localities. Hornblende in fine 
crystals at Sterling mines. Serpentine is found in connection with the 
iron ore at the O'Neil and Forshee mines. A large vein of this sub- 
stance exists in Warwick, on the east side of Long pond; its breadth is 
unknown. It is exposed ten feet wide and fifteen feet deep; its colour 
is dark oil green, approaching black. 
The foregoing rocks form the great body of the Highland mountains 
in the county. They also constitute the rock of many of the short iso- 
lated mountains, at a distance from the foot of the Highlands proper, 
on the northwestern side. Woodcock mountain, in Blooming-Grove, 
is formed of the granitic rock. It is a mile wide at its northeastern ter- 
mination, and three miles long. 
Round hill, in the same town, is another mountain of the same rock. 
It resembles very much a half sphere. Pedler hill, in the same town, 
is still another mountain of granitic rock. Goose pond. Sugar Loaf, 
Sugar Loaf Mate, Brimstone hill and Snake hill, are all primitive ele- 
vations in Goshen and Warwick, separate from the Highlands by in- 
tervening mountain ridges of transition and secondary rocks. 
Mount Eve and Mount Adam, in the town of Warwick, near the 
Walkill, are also primitive mountains, formed of sienitic and gneis- 
soid granite. Pochunck mountain, the most westerly primitive rock east 
of the Delaware river, has its origin on Pochunck neck, in Warwick, 
and passes into New- Jersey. Snake hill, in New- Windsor and New- 
burgh, stands like a primitive island, surrounded completely by transi- 
tion rocks. 
Four miles north of Newburgh, is a hill composed partly of the gra- 
nitic rock. This hill is the farthest north and west of any primitive 
rock east of Sha wan gunk mountain. 
Half a mile northwest of the village of Washingtonville, in Bloom- 
ing-Grove, on the farm of Mr. Joseph Moffat, is the last and smallest 
primitive elevation in the county. It scarcely rises above the surface 
along the western margin of the limestone, and underlays only a few 
acres in extent. 
All the primitive elevations last mentioned, have a line of bearing 
similar to the great Highland chain, and their dip is the same, and in 
the same direction, viz: to the southeast.
