three and a half miles from the boundary. The stream at first runs a 
little south of east, but at the point where the principal excavations have 
been made it turns and runs northward. So that here there is a basin 
in which the drift has accumulated to the depth of fifteen or twenty 
feet. The upper portion, which consists of a very coarse gravel and has 
a thickness of three or four feet, was probably deposited by the stream, 
and it contains no gold. The portion below consists of both coarser and 
finer material, from clay to boulders eight or ten inches in diameter. 
Through this the gold is irregularly distributed, but it is most abundant 
near the bed rock, which here consists of an argillaceous schist, quite 
fissile, and containing numerous cavities filled with a yellowish powder. 
This mine has been worked during the summer months every year since 
1866, and from ten to twenty men have been employed by the proprietor, 
J. H. Pope, M. P. 
As gold was found immediately north of New Hampshire, and since 
the drift through which it was distributed came from the northward, the 
drift stria where they were noticed being S. 28° E., there is every proba- 
bility that gold will be found within our limits. But prospecting in a 
wilderness ten or fifteen miles from the habitations of men, where the 
places can be reached only on foot, requires a great amount of time and 
labor, and therefore our explorations have not been so thorough as they 
might have been under more favorable circumstances. 
In my explorations on Indian Stream, I employed an Indian, Mr. A. A. 
Annance, who was formerly a student at Hanover, but who now prefers 
hunting moose and trapping sable to studying calculus and reading 
Greek. The points examined were on and near Indian Stream, about 
three and a half miles from the boundary. The stream here is quite 
rapid, and on either side the hills rise three and four hundred feet above 
its bed, while every few rods, either from the east or the west, it receives 
a tributary. The rocks here, as elsewhere on Indian Stream, consist of 
argillaceous schists. These are often so wrinkled and corrugated that 
it is difficult to determine the dip, while elsewhere, especially where the 
rock is of a coarser texture, the flexures and contortions are not seen. 
In every respect the rocks are similar to those of Ditton. Immediately 
on Indian Stream the gold is chiefly found in the fissures of the schist, 
which is here so fragile that it is easily broken up by picks. A quarter
