METALS AND THEIR ORES. 4I 



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 is a drift of 30 feet; and at the 100 feet level is another 

 drift 40 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, sliaft 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-
