Epidoie, massive and in crystals, Ciiester, Vt. This is

 of Proctorsville, Cavendish, Vt. 



Marble, wrought at Swanton, Vt. of two kinds. The 

 one is black, and is brought principally from Missisque 

 Bay, within the Canadian territory. The other, which is 

 dove-coloured, occurs about one mile south of Swanton

 and polishing this substance. Both kinds are susceptible of 

 an excellent polish, and are manufactured into tombstones, 

 chimney-pieces, window-caps, &ic. Sic. ; and the marble is 

 transported, for sale, to Montreal, Quebec, Boston, New- 

 York, and various other places.
