Ant. IL. Account of a singular position of a Granite Rock, 
by the Rev. Extras Cornewivus, (with a print.) 
: Salem, Mass. April, 1820. 
TO PROFESSOR SILLIMAN. 
In communicating the following fact, it is not supposed 
that any new evidence will be furnished of a distinction 
which has long been made in the relative formation of dif- 
ferent rocks. It is offered merely as another example of a 
primitive limestone ; attended with such unequivocal indi- 
cations-as to place its geological character beyond a doubt. ~ 
In the town of North-Salem, and state of New-York, 
there is a rock, which from the singularity of its position has 
long attracted the notice of those who live in its neighbor- 
hood, and from its vicinity to the public road, seldom es- 
capes the observation of the passing traveller. It has not, 
however, it is believed, ever been described. It is situated 
two miles East of the academy in North-Salem, within thir- 
largest of them all, stands at the lowest point of that part of 
the surface over which the rock is elevated, and supports its 
other end. Notwithstanding the form of the rock is very 
irregular, and its surface ctnsiderably uneven, its whole 
weight is so nicely adjusted upon these seven small points, 
one of which is six feet from the others, that no external 
force yet applied has been sufficient to give it even a tremu- 
lous motion. 
_ But the singularity of its position is not the most irfterest- 
ing circumstance which meets the eye of the geological ob- 
server. Upon examination, he finds the rock and its pillars
