Highlands OF the Hudson. Oh the north side OF
the Sscandsgs Creek, between the towns OF Had

full heshcolored feldspar is found rising through
the gneiss and it runs for tVO or three miles 10
southwest course. L. has been and still is called
granite by the people ia the vicinity, bot SIS there
are no mica and quartz in it, it cannot be classed
with the genuine granite. IL assumes beautiful

In the Chatea1gua aud Clinton ranges, and fre-
Quently in the intervening valleys and ridges,

it is observable ia Johnstown and May field, in
Fulton County, where the soil is composed OF sto-
Dy argillGceous loan, and rests principally upon
lower secondary slate, with come sandy ldvion,

stone which appears to be composed of the finest
particles Of quartz and mica intimately blended
with small quantity of feldspRr. Stratifcstions
OF this stone are also observed in the banks and

the river flows about two or three miles from
