face of the Country is delightful, and its Produce 
to the Husbandman almoft exceeding his Hopes : But 
what renders it ftill more furprifing, is, that a Coun- 
try, whofe Soil yields to few in Fertility, and the 
Beauty of its Bloom, fhould yet cover immenfe 
Riches in its Bofom. Here are Mines of Gold and 
Silver, which have long been worked to Advantage: 
The Veins are rich, and liefhallow; yet communi- 
cate no poifonous Effluvia to the Vegetables that 
cover them : Nor do thofe diftinguifhing Marks of Ste- 
rility appear here, which in moll other mining Coun- 
tries are fo obfervable. 
The higheft Part of Sibiria is towards the, Springs 
of the Rivers Argun , Schilca* &c. about the 49* 
Deg. of Lat. 130^ Longit. This Part is defiitute 
of Marble and Lime- Stone, which are almoft every- 
where to be met with in the lower Tradts both of 
Sibiria and Ruffla : No Petrilications are to be found 
here, either of the teftaceous or cruftaceous Ani- 
mals: And the Veins of Ore are always found near 
the Surface, never entering deep into the Earth. 
Befides the Mines of Gold and Silver above-men- 
tion’d, Copper and Iron are found in feveral Places j 
likcwife the Glacies Maria or Mufcovy Glafs is dug 
near the River Mama. Loadftones are alfo got in 
Sibiria ; and in feveral of the Rivers beautiful tranf- 
parent Pebbles and Chryftals occur. 
I (hall only add, that there are fome natural warm 
Baths in feveral Parts ot Sibiria , and fome of them 
of a moft agreeable Temperature ; and proceed to 
the Account of our Author's Obfcrvations and Ex- 
periments on the Height of the Earth, &c.
