inence — the former appears most probable. The ore is fissured as 
in the Parish bed, but differs from that in presenting seams of stra- 
tification parallel to its outline. This bed has not been so exten- 
sively worked as the last, though several thousand tons have been 
taken from it. The ore continues of an uniform character to the 
depth to which it has been penetrated, — not exceeding eight feet. 
A bed of similar ore occurs in Canton, which was formerly 
worked, but has since been abandoned: the failure probably arose 
from attempting to work it by a forge fire instead of a furnace. 
Beds of this ore occur at Gouverneur, Edwards, Fowler, and 
Scriba — in all eight or nine — but I am not aware that any have 
been worked for manufacturing purposes, except the two at Ros- 
sie, and the one at Canton. 
There are indications of other beds in the vicinity of those just 
mentioned, which, from appearances on the surface, are probably 
extensive. Where a bed of this ore approaches the surface its 
presence is known by the red color of the soil, given by the oxide 
of iron. 
These ores are first reduced to pig iron, and afterwards convert- 
ed into malleable iron; while the magnetic ores are manufactured 
directed into malleable iron. 
Origin of Specular Ore. 
The specular oxide of iron appears to have been formed at the 
same time as the rocks which embrace it, though in some places 
there are appearances which would indicate a later origin: or per- 
haps, that the ore was an aqueous deposite and has since been 
changed by heat. It does not, however, concern our present pur- 
pose to discuss theories upon the subject. 
III. BOG ORE. 
General Remarks. 
This ore is most extensively distributed on the north and west 
of the mountainous region, as we descend towards the St. Law- 
rence river. It is most abundant in St. Lawrence county; 
though numerous and extensive beds are found in Jefferson, Frank- 
lin and Clinton counties. The face of the country and other cir- 
cumstances are more favorable to its formation in these counties, 
than in Essex, Warren and Hamilton.
