Havine =xansihed the rocks in this place, Tam age 
to mention a few facts relative to their position, and to t 
minerals they contain. 
On the mountain, 5 alee west of Westfield Academy, are 
two beds of serpentine; one of which, has never been men- 
tioned in the geological accounts of this region, that have 
heen published. It is imbedded in mica slate, and associated 
with primitive carbonate of lime. ‘The limestone is at 
south end of the bed, and they pass into each other, forming 
a stratified rock, with strata nearly perpendicular to the ho- 
rizon. These strata, for the most part, seem to be alterna- 
tions of Serpentine, and an unknown mineral resembling 
lime, about one inch in thickness. Sometimes they are found 
peried together, forming a compound similar in appearance 
Verd Antique. Here are found also veins of the 
same unknown mineral, serpentine, and green talc, associ- 
ated as ee in the following profile,
