METALS AND THEIR ORES. 41 
veins cross this land,—one to the east, and two west from the shaft. Two or three 
other openings upon this land show more copper than at the shaft. This shaft has been 
sunk through the sandstone belt, which is 13 feet wide at 160 feet. The schists on the 
east are 100 feet wide before striking the next sandstone beyond, which is the most 
eastern copper belt. 
' During the winter of 1878 work has been continued, and the shaft is now down 200 
feet. At the 60 feet level isa drift of 30 feet; and at the 100 feet level is another 
drift 4o feet long. The mine is named from F. P. Haviland, of Waterville, Me. 
Stevens Mine. This lies near the north line of Bath, to the south of the Haviland. 
It contains 130’acres of tillage, pasturage, and woodland, and lies upon the southern 
slope of the Gardner mountain range. In coming from the Haviland mine the contour 
lines show a slight change in the direction of the mountain.. The mining improve- 
ments consist of a small boarding-house, shaft house with a shaft 100 feet deep 
(Sept. 26, 1877), cross cut 150 feet long at the bottom, and four other small openings 
in various places. 
The shaft follows down a band of cupreous schists several feet wide, the angle of 
descent being greatest at the top. Three prominent bands of copper ore are seen at 
the surface, gradually widening in the descent, each one being twelve inches, and solid 
at the bottom. Prof. Bartlett’s assay gives $37 worth of gold to the ton as coming 
from the pyrrhotite in these seams. There is a large pile of this ore outside of the 
shaft house. About 200 feet west is another vein showing copper ore along a breadth 
varying from two to eight feet, the gangue being white quartz with the mineral scat- 
tered through it, instead of cupreous argillitic schists, as in the first instance. This 
has been opened some ten or twelve feet in depth. There is a third vein about 150 
feet east of the shaft, which can easily be reached underground from the main shaft. 
A fourth vein occurs 400 feet east of the shaft. Thus three veins are reached by one 
shaft less than 400 feet apart. In April, 1878, I learn that the cross cut 100 feet deep 
has reached the vein to the west, and ore is being raised from it. The ‘silver vein” 
is an opening on the southern slope to the west of the copper excavations. There is 
here a trench 25-30 feet in length, displaying a vein of galena 18 inches wide. Sev- 
eral barrels of this ore have been taken out. It is said to contain, of silver, $50 to the 
ton. It is of value in the future development of the country in connection with the 
argentiferous veins at the Paddock lead and copper mines. An unusual feature of the 
Stevens property is the occurrence of numerous boulders of copper and iron pyrites on 
the south slope. By reference to the maps it will appear that the main ridge of the 
Gardner mountain is bent to the east as it passes into Bath, and diminishes in size. 
It is on that southern slope that these boulders occur, noticed even twenty-five years 
ago. Such stones have not been observed on the eastern slope of the mountain all 
through Lyman. While it is possible they may have been derived from the veins to 
the north, the laws of boulder distribution imply their derivation from some locality 
near at hand, perhaps not north of the Bath line. Their occurrence recalls the discov- 
ery of the valuable mines about Capleton, P. Q., from similar indications. The pres-
