Plumbago. — la Cornwall, Litchfield county, Connecticut, 

 plumbago is found, of a good quality, and in considerable 

 masses, in a vein contained in a rock of gneiss, or mica-slate. 

 It has been known a good while, and is said to have been ex- 

 ported anterior to the American revolutionary war. 



Coal, ^c. 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 in the above town, in the spring of 1817, through free- 

 stone, trees, and fish, and other substances, both animal and 

 vegetable, were taken out, alilte petrified to a freestone, ex- 

 cepting the bark of a beach tree, which was very perfect and 

 beautiful coal — (as we have had an opportunity of ascertain-

Coal, in the county of Muskingum, Ohio. Common stone-

 is found abundantly. 



South of Lake Erie, about 25 miles, in the bed of Rocky

 in argillaceous iron ; the specimens were collected in 1817, 

 by the Rev. R. Searle.

 the Rev. E. Cornelius, a mammoth's tooth, apparently not 

 mineralized. It appears to have belonged to a very old ani- 

 mal, as the processes, (which, it is well known, are commonly 

 very prominent) are worn down smooth, and some of them 

 almost 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, 

 illustrative of the mineralogy and geology, and Indian antiqui-

 subject of more particular remarks. 



Coal, in Suffield, Connecticut, on the river of the same 

 name. From Mr. Nathan Stedman, we have received speci- 

 mens of coal, found in thin veins, in rocks of slate, and argil- 

 laceous sandstone, on the banks of the river. The veins are
