the series of the shales and sandstone of the southern counties. In no 
part of either Herkimer or Oneida, does this rock form a continuous mass 
east and west, being cut down to the limestone by the streams which 
flow south, dividing it into ranges, the intervals being filled with deep 
deposits of alluvial. 
Metallic minerals or ores are rare in all that part of Herkimer county, 
which we examined. On the farm of Josiah Rice, about two miles from 
Salisbury corners, diggings have been made in the calciferous sandrock, 
which have furnished small quantities or specimens of sulphuret of lead, 
zinc, iron and copper, also stains of green carbonate of copper and bog 
ore, derived from the decomposition of the pyrites. There is no appear- 
ance of veins, but strings or little bunches appearing and disappearing 
without any regularity. Most of these ores, with coal and rock crystals, 
are found near the village; the same locality noticed in the survey of the - 
Erie canal. 
East of Salisbury Comers, distant about three miles, and in the re- 
gion of the primary mass, an aggregate of granular carbonate of lime, 
and that variety of amphibole called coccolite, is found. It was blasted 
for marble. It is beautiful from the contrast of the green and white of 
its constituents, but does not show signs of abundance. It is on the 
land which formerly belonged to Col. Drake. 
ONEIDA COUNTY. 
The northern edge of the millstone grit corresponds very nearly with 
a line extending through the villages of New-Hartford and Vernon Cen- 
tre. It shows itself in the water courses to the east of Utica, near 
New-Hartford in many places, south of Hampton village, also at Onei- 
da springs, and the stone pound near Stony creek to the north and west 
of Verona. 
By the lines of separation in the layers of this rock being more or 
less angular, and from similar kinds of markings on other parts of this 
rock, we have proof that the waters which deposited this mass were 
subjected to various movements. 
The locks and other masonry of the Chenango canal near New-Hart- 
ford are formed of this rock. It is there in part stained with iron from 
the alteration of the pyrites, which is not common to this rock, except- 
ing as mentioned before, in the lowest part of its lowest layer. It pre- 
sents likewise a few of the large imperfect fucoides, and no other fossil.
