Geological Reports. 185 
6. Culpeper Gold Mine, Virginia. PE a 
Since the printing of the notice of this mine, and of the other 
gold mines in Virginia in the present number of this Journal, we have 
received authentic information from an authority entitled to full credit, 
that every appearance about the Culpeper mine is very favorable to 
good success. The workings have been much extended, and new 
explorations have taken place, disclosing rich and increasing = 
of gold. 
The stamping and amalgamating works are far advanced upon an 
extended scale; they are now equal to the exigencies of the mine 
and will be extended with its progress. Large supplies of ore are on 
hand, and arrangements are made, or are in progress, to furnish a full 
supply to the powerful machinery prepared for its reduction. The 
expenses are kept within moderate limits, and there appears goad 
reason to expect a favorable result of the enterprise. 
7. Geological Reports. 
I. Report of a Geological Reconnaissance, made in 1835, from 
Washington, by Green Bay, and the Wisconsin Territory, to the 
Coteau de Prairie, an elevated Ridge dividing the Missouri from 
the St. Peter’s River; by G. W. Fearunerstonnauen, Esq. Doc. 
No. 333, printed by order of the Senate, Washington, 1836, pp. 168, 
with two large maps and four plates of illustrative sections_and dia- 
grams. 
The plan of this report is beteptially the same with that of the 
preceding year. The greater part of this report is occupied ‘by an 
elementary sketch of geology, with occasional elucidations from Bee 
logical facts in this country. 
The geological narrative begins at the city Washington, and 
contains a sketch of facts on the line of the Potomac to Cumberland 
“—then by Bedford in Pennsylvania, to Pittsburgh—by |the Ohio to 
the great lakes, and through them to Green Bay, lake Michigan— 
thence by the Fox River, lake Winnebago, the Wisconsin, &c. to 
the Mississippi—up that river throngh lake Pepin tothe falls of St. 
Anthony and St. Peter’s river—thence up that river_to its source— 
thence to the Coteau de Prairie, and back to the Mississippi and St. 
Louis, by the way of Dubuque’s Lead Mines. 
In this wide range, the author met with many interesting facts, which 
are presented i in an —— form, and it is obvious that the adven-
