350 Mineralogy of Jefferson and St. Lawrence Counties, N.Y. 
of the Hemlock, and both hemlock and birch roots, from one to two 
feet in length, and several inches in diameter, which, although they 
are completely converted into bog ore, retain their original appear- 
ance very perfectly. In the same town, ten miles south of the fur- 
nace at Fullerville, is a rich deposit of iron ore, known as the Wil- 
son ore bed. Here we find the red oxide and the granular mica- 
ceous oxide of iron. This last contains numerous cavities or geodes, 
completely studded with thin very brilliant plates or crystals, resem- 
bling specimens of the same ore from Elba. The proprietor of the 
furnace at Fullerville, attempted to work this ore, but owing to some 
unknown cause, he did not succeed in reducing it. He states that 
when he was attempting its reduction, the furnace was filled with very 
offensive fumes, which, as he supposes, caused the sickness of seve- 
ral of his workmen, and in consequence, the ore, which is undoubt- 
edly very rich, was abandoned. 
No odor is perceptible when this mineral is struck with a hammer, 
or when submitted to the flame of a lamp, urged with a blow-pipe. 
From Duane, Franklin Co. we have hypersthene and octahedral 
iron ore, strongly magnetic ; a piece weighing about four ounces lifts.a 
Jarge nail. It is said to be abundant. 
A singular iron ore has recently been buiaaiad at this place by 
ane Duane, which i is capable of iaing sarge directly into steel, 
r. Duane has erected ex- 
tensive works for the conversion of this ore into steel, and the article is 
in market, and bears a good price. This ore is not the spathic 1 iron 
or proper steel ore. It resembles the octahedral iron, but is only 
slightly attracted by the magnet. Itis perhaps a form of the specu- 
lar iron, but we were not aware that this ore was capable of being 
manufactured directly into steel. 
Plumose Iron Pyrites in fine specimens; is found at Champion, in 
Jefferson Co. 
Galena in rolled masses of considerable size, is found in’ alluvial 
earth and clay, near the shore of Lake Ontario, in the town of Hen- 
derson, Jefferson Co. Since our visit to these localities, we have re- 
ceived through Dr. Murdock, of Gouverneur, copper-colored mica in 
broad folia. Among our specimens we notice rhombic prisms (the 
primitive form) and six sided prisms several inches in diameter. 
_ As soon as other engagements will permit, we intend to explore 
this pow more thoroughly, as we have no doubt it will richly repay 
any t for the time he may devote to its examination.
