Mines of Berezovsk. — The detritus of Gold veins and Mammoths’ bones therein. — Mines of 
Chrestovodsvisgensk with Gold and Diamonds. — Mines of Peshanka near Bogoslofsk with Gold, 
Mammoths bones, &c. — Ores of Platinum as well as of Gold occasionally formed by diffusion 
through the Rocks — Auriferous and Mammoth detritus along the East Flank of the Chain to 
Soimanofski Zavod. — Great richness of similar accumulations south of Miask. — No traces of 
action of the sea on the East Flank of the Chain from after the Palteozoic period to the present 
day. The Gold bhingle of the Ural and its overlying Clay formed in the Lakes of an ancient 
Siberian Continent, where the Mammoths and other extinct Animals lived. — The fossil Mam- 
malian Remains carried for ages into Lukes and Rivers, and thence into Estuaries and the 
Northern Sea. — Their final destruction probably caused by the last elevations of the Ural. — 
The Remains of fossil Animals in the Drift of European Russia considered. — The supposed 
preservation of the Bos Urus to the present day explained. — Relative changes of Sea and Land 
considered 471 
CHAPTER XX. 
SCANDINAVIAN DRIFT AND ERRATIC BLOCKS IN RUSSIA. 
General spread of a Drift from the North over the Low Countries of Russia and Germany. — Theories 
proposed to account for Foreign Drift— The Russian Drift and Erratic Blocks described along 
the northern frontier of Russia. — Shown to have been distributed in trainees under the sea. — 
Chiefly arrested on Hills and elevations, and less abundant in Depressions. — Large Blocks most 
frequent on Clay, and broad low sandy spaces often free from them. — Character of the Drift 
changes in its advance southwards, according to the nature of the subsoil which it traverses. — 
Distinctions between the Local Materials in Russia and those of Poland and Germany. — The 
tiansport of the Drift from lower to higher lands shown to be impossible under terrestrial con- 
ditions ; and the Glacier Theory, as applied to these Regions, rejected. — The far Southern and 
South-eastern advance of the Drift into certain Depressions explained by reference to Bays and 
Promontories of a former Continent. — Erratic Blocks shown to have proceeded excentrically 
from Scandinavia and Lapland. — The largest and furthest-borne supposed to have been trans- 
ported in Icebergs detached from ancient Glaciers. — The low northern Crystalline Tracts could 
not have determined the advance of Glaciers over a higher Continent. — Scratched surfaces 
coincident with the direction of the Drift over many Low Countries of Europe. — Theory of the 
Authors of this work explained, viz. that moistened masses of Drift have, under powerful causes 
of translation, operated like the Moraines of Glaciers.— Former Submarine condition of Russia. 507 
CHAPTER XXI. 
DRIFT AND ERRATIC BLOCKS OF SCANDINAVIA {continued ). — ABRASION AND 
SITUATION OF ROCKS. 
Detritus of Denmark shows the long continuance of submarine conditions, and the dispersion of 
Boulders at various periods. — Striation, and its excentric direction in Norway as well as in 
North-eastern Lapland, prove the Northern Scandinavian Mountains to have been the Centre
