ECONOMICAL MINERALOGY, 
On the farm of Mr. H. W. Gott, two miles west of Austerlitz, where it occurs in a marsh, 
and is deposited like bog iron ore. It is thought to be an extensive bed. 
On the farm of Mr. Judson Park, a mile south of the above, there is said to be another bed 
of the same mineral. 
Several similar localities are reported to exist in the northeastern part of the town of Aus¬ 
terlitz. 
Also on the farm of Mr. David Parsons, three quarters of a mile south of Canaan Centre ; 
and on the farm of Mr. Joseph Goodsell, in the town of Hillsdale, &c. 
Mr. Mather states, that in the counties of Columbia and Dutchess, 50,000 tons of wad could 
be procured without any great expense. If carefully prepared, it would be worth $20 a ton, 
or for the whole amount $1,000,000. 
In Cattaraugus County, the black oxide of manganese has been found in small grains in 
various parts of the Conewango and Little valleys; but the quantity is too small to give it 
any value. The same is also true in regard to the occurrence of the hydrate of manganese in 
the County of Allegany ; the lamellar variety of which, according to Mr. Vanuxem, is found 
associated with calc tufa near Angelica. 
Essex County. On the sands near the village of Keeseville, there occur small rounded 
masses of a reddish brown colour externally, which, upon analysis, are found to contain a 
considerable proportion of oxide of manganese. 
Lewis County. On the summit of Tug hill, about two miles from the village of House- 
ville, there is a bed of the earthy oxide of manganese in a marsh. It varies in depth, as at 
present exposed, from three to eight inches, being made up of rounded masses of various sizes. 
It is somewhat doubtful whether this is an extensive bed, and I am not aware that any means 
have been taken to determine the point. 
New-York County. This mineral has long been known upon the Island of New-York, 
where it occurs in hollow friable masses in alluvial hills. The quantity, however, is small. 
Orange County. Four miles southeast of Warwick, there is a compact variety of the 
oxide of manganese, which, however, is largely mixed with oxide of iron and earthy matters. 
Westchester County. In the dolomite near Sing-Sing, there are occasionally found 
nodules of compact black oxide of'manganese. They possess a higher specific gravity than 
most of the specimens of wad already described, and have a minute portion of copper com¬ 
bined with the manganese. They may belong to the variety noticed by Cleaveland under the 
name of Cupreous Oxide of Manganese. 
These, with the addition of the small masses occasionally met with in the slates of Albany- 
and Rensselaer Counties, constitute the New-York localities of this mineral. It is usually 
quite largely mixed with the oxide of iron and other foreign matters, which would of course 
detract from its value as an article of commerce. The following table will exhibit the results 
of the several analyses which I have made of this substance from different localities.
