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 striae v/here 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
