falls of llic Saranac, at Miller's settlement. The quality of the ore, so far as inspection alone 

 can determine, is good ; being free from pyrites, phosphate of lime, etc., and moreover rich 

 in iron. Wiihin half a mile of the vein, there is sulficient water power for moving the ma- 

 chinery of a forge or furnace ; and witlial the vein is situated in the midst of fuel necessary 

 for reduction, suiScient for a long period of time. In this locality, I observed no fact not 

 already stated, in illustrating the phenomena of veins of iron ore. 



Anotiicr vein of ore, not far from this neighborhood, has been discovered on Chub river. Its 

 appearance indicates an ore of like quality with that just described. 



While at Miller's settlement, I was informed that a vein of black ore had been discovered 

 near Tuppcr's lake. Of this I cannot speak with confidence, having never visited the place 

 where it is said to have been found. 



It is a fact worthy of remembrance, that it is rare to find a single insulated vein, or one 

 that is entirely alone and unaccompanied with other veins. There seems to be in general a 

 cluster of veins somewhat central to a main deposit ; and hence, when one has been discovered 

 in a section of country, it may, agreeably to experience and observation, be expected that 

 more still exist in the vicinity. From the mode, however, in which many veins occur, it is a 

 matter of chance whether they are discovered or not, as frequently they do not reach the 

 surface. 



Conger ore. There is a cluster of veins, apparently of some importance, in township No. 

 11, near the Port Kent and Hopkinton turnpike road, on lands owned by Mr. Conger. The 

 Conger ore is black and coarse grained. On recent fracture, tlie lustre is bright. Some 

 portions are fine grained, intermixed with decomposed feldspar. It contains also white flint, 

 and some that is rusty brown. This ore, as well as the preceding, is in gneiss, in which 

 hornblende, black mica, etc., form an essential part. So far as circumstances for reducing 

 ore are concerned, they are favorable at Conger's, being in the midst of a wooded region, and 

 in the vicinity of sufficient water power, near the great falls of the St. Regis. 



In this same region, in township No. 8, three or four miles from Conger's, veins of mag- 

 netic oxide have been discovered, but they require farther examination before their characters 

 can be fully determined. 



Ores of Duane. 



With the village of Duane as the centre, several veins are known to exist within a circuit 

 of four or five miles. 



Deer River ore. Lustre resinous and somewhat shining, but in parts dull. Breaks into 

 angular fragments, the form and shape of which are determined by natural joints indicating 

 cleavage planes, the surfaces of which are covered with a coating of green earth, or chloritic 

 matter, which is not uncommon in ores of this description. The seams too are often incrusted 

 with yellowish oxide of iron. Intermixed also with the ore, I observed some hypcrsthene. 

 The vein is traversed longitudinally with seams of light-colored feldspar, especially by that 

 portion containing hornblende. The faces of the hornblende have a glassy lustre. The 

 gangue of the ore is principally hornblende, and coarsely crystalline, intermixed with large
