per cent.; in No. 3, to 38.10 per cent.; and in No. 4, to 19.35 per cent. 
No. 4 also contains 3.17 of copper and 16.62 per cent. of zinc. 
On examining the veins to the north the sulphurets are found cropping 
out on the. surface for one or two hundred feet, and the vein itself can be 
traced on the property nearly to a house eighty rods distant. Further 
tracing was not attempted in that direction. It is common for this vein 
to be cut by irregular veins of white quartz. 
The outcrops are on a steep hill, perhaps three hundred feet above a 
comparatively level tract. Thus the vein could be easily drained, 
whether an adit be driven into the hill at right angles to the vein, or 
from the north and driven in on the vein itself. This site is less than 
three miles in a gently ascending country from Northville (Newport), on 
the Concord & Claremont Railroad. 
Neal Mine. Next in value is the Neal mine in Unity. This has been 
visited three times. It is owned by the Neal family, and is about four 
miles from North Charlestown. The vein has been described in Dr. 
Jackson’s report. It is a mixture of iron and copper pyrites, nearly three 
feet wide, and has been traced fully 2,200 feet in length. Drainage can 
be effected to the depth of seventy feet. The vein dips 78° W. 10° N. 
It has the same geological position with the Croydon mine, lying near 
the western border of the gneiss, and if the ores were mixed it would be 
difficult to distinguish many of the varieties from each other. It is 
probable that the ore would all become copper pyrites at 100 feet or 
more below the surface. 
There are other interesting veins on this property, but it is only suffi- 
cient for our present purpose to say that the pyrites can be as profitably 
mined for sulphur here as at Croydon, and if copper or other valuable 
metals should be ultimately discovered in abundance, it might be 
wrought for them also. 
Other veins carrying considerable amounts of pyrites, which are all worthy of ex- 
ploration with the hope of successful results, are the King property, upon C. Houston’s 
land, in the south-east part of Hanover; the land of J. W. Cleaveland, of East Leba- 
non, in the north-west part of Enfield; in the south-west part of Lebanon; Dr. Hub- 
bard’s mine on the Jackson farm, in the south part of Claremont. On account of the 
great value of this ore in the manufacture of fertilizers, it is to be hoped that these 
veins will be thoroughly explored, the market well supplied with sulphuric acid, and
