Copper. 



Several valuable veins of copper ore have recently been discov- 

 ered at West Quoddy Head, in Lubec, by Prof. Shepherd. We 

 insert his letter respecting them. The south part of Washington 

 county seems to be a very rich metalliferous region, and deserves 

 further exploration : 



Eastport, July 22, 1862. 



It is with great pleasure that I have recently observed six vp'ell 

 defined spar veins from one to two feet in diameter, four of which 

 show copper ore on the surface. These veins are situated on the 

 land of Benj. Fowler, Esq., at West Quoddy, near the Carrying 

 Place. 



One vein appears rich in the yellow sulphuret, and another yields 



specimens of the purple or horse-flesh ore, and all give promise of 



future mineral wealth. Still another vein on the same property, 



although somewhat subdivided on the surface, yet carries yellow 



copper ©re, accompanied with magnetic iron pyrites. Were this 



property on Lake Superior it would probably be taken in hand at 



once. 



FORREST SHEPHERD. 



Upon page SO"? of the Preliminary Report, mention was made of 

 the discovery of native copper in No. T, near Carroll. The speci- 

 mens were shown us subsequently, and are the genuine mineral. 

 We made an effort to find the vein, in company with Mr. Levi 

 Bailey, who procured them at first. He was unable to find the 

 exact spot. The rock is a coarse granite, and is not promising for 

 such ores. The true locality must be further south-west. The 

 rocks on Nickatou's lake have been described to us in such a way 

 as to make us anxious to explore them for copper. 



We have already spoken of the copper mine in Woodstock, and 

 of the peculiar syenitic rock containing the veins. The occurrence 

 of a similar rock on the Maine side of the line should be examined 

 carefully for metalliferous veins. 



The probability of finding copper ores in the north-west part of 

 the State, on the river St. John, is confirmed by the wonderful 

 extent and richness of the copper ores in Lower Canada in the 

 same formation. It is but recently that the Canadian rocks were 

 supposed to be as destitute of copper ores as the corresponding
