Jsfotice of a Mineralized Tree^ ^c^ 251 



The Iron ore is the common brown hematite, with some 

 argillaceous oxyd of iron. Yellow ochrd is also found in 

 considerable quantity* The ore much resembles that of the 

 mine in Salisbury, Con.; but the stalactitical form is rare 

 here and not so beautiful. 



The ore of Manganese Is the common black oxyd, gene- 

 rally compact, sometimes mammillary or botryoidal. The 

 excellence of this ore is well known. Many tons are annu- 

 ally carried to market for the purpose of bleaching. The 

 price at Boston varies from forty to fifty dollars a ton. It is 

 also coming into use, as a substitute for red lead, in the gla- 

 zing of common earthen ware. 



One specimen of fluate of lime, crystallized and very 

 beautiful, has been found with the manganese. 



Similar iron ore is also found in the north-western part of 

 Bennington. It occurs in beds of one or two inches to six 

 inches in depth, in a loose soil lying upon limestone rocks. 

 Those beds are of small extent, and probably are not con- 

 nected with any bed like that described above. 



It has been remarked that the great bed of ore is not 

 immediately connected with any rocks. It seems, hovvever. 

 to be associated with limestone rocks, and the whole to lie 

 between two strata of mica slate. It lies in the same range 

 with the ore of Salisbury, Con. and has the same range of 

 mica slate lying on both sides of it. The same kind of ore 

 is found in scattered pieces on the surface in several of the 

 towns in this County, and in Lenox it "occurs in abundance*

1. Mineralized Tree, ire. i^c. 



About half a mile from the villageofChitteninffO, in Sul- 

 livan County, (New-York) a fossil or mineralized tree 

 was some years ago discovered. It lies at the base of the 

 Conasewago mountains, within a few yards of a branch ol 

 the Erie canal, which runs up to the village. The tree ap- 

 pears to have been blown down and broken off— there are 

 eight or ten feet of the stump remaining, with some part of 

 the large end near the root— the stump is about three feet
