great part of the state. The mineral is scattered over the 
surface, and for the most in irregular pieces, yet some tole- 
rable crystals are found, from a few grains to 20 lbs. weight. 
Iam not yet able to give you all the information I could 
wish, but in a short time you may expect a more particular

8. Notices of minerals and rocks chiefly in Berkshire, Mass. 
and contiguous to the waters of the upper Hudson, and 
the lakes George and Champlain, with occasional re- 
marks on other subjects.—Editor. 
Ina short tour for health in the latter part of last May and 
the beginning of June, in company with Mr. S. F. B. Morse,

without interruption, for hundreds of miles, there seems to be 
no good reason for regarding it as merely asubordinate rock ; 
it would seem to be as truly a regular member of the series 
of primitive rocks, as the mica slate and gneiss in which 
these strata are generally imbedded

and therefore partakes of its direction, which is s nearly N. E.
