40 Miscellaneous Notices of American 
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 fewgrains to 20 lbs. weight. 
J am not yet able to give you all the information I could 
wish, but in a short time you may expect a more particular 
account respecting it.

6. 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, 
through a part of Berkshire and Vermont, and around the 
waters of Lakes Champlain and George, and the upper 
Hudson, a few observations were made, which may possibly 
be of some use to future travellers. They are presented, 
not as bearing, by any means, the character of thorough re- 
search ; they were merely such casual notices as an invalid 
could make without much effort or sacrifice. 
Marble beds of West Stockbridge and Lanesborough, Mass. 
This is a part of the great northern region of white prim- 
itive granular limestone or marble, now so well known 
throughout the United States. These beds are evidently a 
continuation of those in Fairfield and Litchfield counties.* 
in Connecticut, and possibly of those at Kingsbridge and on 
the Schuylkill, near Philadelphia. It was remarked by 
Mr. M. that if primitive limestone thus extends, probably 
without interruption, for hundreds of miles, there seems to be 
uo 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. 
At West Stockbridge, as far as we had opportunities to 
observe, the primitive marble lies between strata of gneiss, 
and therefore partakes of its direction, which isnearly N. F.
