Plumbago.—In Cornwall, Litchfield county, Connecticut, plum- 
bago is found, of a good quality, and in considerable masses, ina 
vein contained in a rock of gneiss, or mica-slate. It has been 
known a good while, and is said to have been exported anterior 
to the American revolutionary war. 
Coal, Sc. in Zanesville, Ohio. Through the kindness of 
the Rev. Dr. Bronson, Principal of the Cheshire Academy we 
have received the following information—In cutting a canal 
inthe above town, in the spring of 1817, through freestone ; 
trees, and fish, and other substances, both animal and vegeta- 
ble, were taken out, alike petrified to a freestone, excepting 
the bark of a beach tree, which was very perfect and beau- 
tiful coal—(as we have had an opportunity of ascertaining, from 
a1 examination of the specimens.) peared a erin 
Coal, in the county of Muskingum, Ohio. Common stone- 
coal, highly bituminous, (the slaty or black coal of Werner,) is 
found abundantly, 
' South of Lake Erie, about 25 miles, in the bed of Rocky Riy-

Rey. R. Searle.

Prominent) are worn down smooth, and some of them are al- 
Most obliterated. 
Blue Ridge, Tennessee, and Mississippi Territory.—Through 
the kindness of the Rev. E. Cornelius, and of Mr. John H, 
Kain, we have received a considerable collection of specimens, 
illostrative of the mineralogy and geology, and Indian antiqui-

subject of more particular remarks. 
Coal, in Suffield, Connecticut, on the river of the same 
fame. -From Mr. Nathan Stedman, we have received speci-_ 
of coal, found in thin veins, in rocks of slate, and argil-
