METALS AND THEIR ORES, 5 
ilar lithological features and dimensions. The metalliferous part is on the south-east 
wall of the quartz, separated by a width of eight inches of fuller’s-earth from a trap 
dyke. A shaft has been sunk 36 feet. The adjoining rock is granitic gneiss. The 
ore is scantily disseminated through a width of four to seven feet, sometimes pinching 
out entirely. It consists of galena, magnetite with blue stains, copper and iron pyrites, 
and zinc blende. This opening was made in 1876. 
In the north part of Wakefield, on the land of Ira Hammond and S. B. Ames, is a 
similar band of white quartz with scanty veins of galena, blende, iron and copper pyr- 
ites. Mined in 1876, and two shafts sunk to the depth of Io and 17 feet. 
In the north-west part of Strafford there is another opening in one of these beds, 
much talked of by the prospectors. I have seen the beds, but not the openings. The 
quartz is of remarkable extent and purity. I should not expect any of these ‘‘ mines” 
to prove profitable. 
The following is the report of Mr. Huntington upon the prospect of 
finding gold in Pittsburg, made in 1871. There is reason to believe that 
explorations for gold in this town may be successful : 
ALLUVIAL GoLp oF INDIAN STREAM. 
In that part of Quebec Province that lies between the St. Lawrence, 
Maine, New Hampshire, and Vermont, the existence of gold in the allu- 
vium has been known for many years. It is estimated that the area 
over which it extends comprises more than ten thousand square miles. 
The gravel containing gold rests generally upon metamorphic schists, 
some of which are associated with diorites and serpentines. Mr. A. 
Michel compares the gold deposits of Lower Canada with those of 
Siberia. In the Ural and Altai mountains the auriferous gravels are 
almost always found reposing on schistose rocks, very rarely granitic or 
sienitic, as along the Pacific in North and South America. He further 
says, that the gold in Quebec Province, “whether in large or small 
.grains, is generally so smooth, so much rounded and worn by friction, 
that it appears to come from some distance.”” * * * “The condi- 
tion of the gold shows it to have been, for the greater part, at least, 
detached, rounded, and ground by erosive action of currents of water.” 
In the town of Ditton, which borders on New Hampshire, and is 
immediately north of the head waters of Indian stream, alluvial gold 
washing, by sluicing, has been carried on for several years. The place 
where the most extensive operations are is on a branch of Salmon river,
