When examined in detail, where any quarries or openings have been made, the 
relations of the intrusive rocks to the sedimentary are very instructive, even around 
Neviansk ; for whilst the coralline limestone in the valley is little altered, yet 
nearer to the eruptive hills it is in the state of crystalline white and green marble, 
from which a statue of the late proprietor has been constructed. 
Again, in the hillocks forming the fore-ground of the sketch, the igneous rocks, 
graduating from greenstone to porphyry and felspar rocks associated with serpen- 
tine, are seen traversing talcose schists, much dislocated and altered, with occa- 
sional coatings of magnetic iron ore \ 
Nijny Tagilsk . — Besides the coralline Devonian limestone, which is traceable for 
about twelve versts, chloritic schists and quartzose rocks, with various eruptive 
masses, lie on either side of the route between Neviansk and Nijny Tagilsk. The 
latter, the chief Zavod of the Demidoff family, with a population of 22,000 souls, 
is truly a well-ordered town, in which the comfortable dwellings of the workmen, 
the capacious hospitals for their relief, the schools for the education of the youth, 
the elegance of the public buildings and houses of the chief managers, and above all 
the skill with which the machinery, forges and works are conducted, would reflect 
the highest credit upon any European establishment*. 
If mineralogical details and all the shades of transmutation which sedimentary 
rocks have undergone during former operations of nature had been our object, a 
residence of a whole summer, instead of two or three days, might have been well 
and instructively passed in this most remarkable spot, the centre of a vast pro- 
perty ; and where, by the instructions of M. Anatole Demidoff, we were received 
as if he had himself visited his mines, and were treated with overflowing kindness 
by his accomplished agents MM. Danilof and Schwetzoft'. Baron Humboldt: and 
M. G. Rose have however, to a great extent, supplied what may be deficient in 
i The population of this Zavod is 17.000, and the inhabitants have a fine rural healthy appearance. 
- The artificial lake for working the mills is of very graceful form and of some extent, and a little 
steam-boat was employed upon it.
