Tlio Yerklineoudiiisk region of tlie Trausbaikal province is situated along the rivers tlouiug 

 into Lake P>aikal, and from it through tlie Angara into the Yenisei. The gold deposits of 

 this region are situated in its south-eastern portion, near the Chinese frontier, along the 

 tributaries of the river Chika, which falls into the river Selenga. These deposits lie in narrow 

 valleys, surrounded by high mountains covered vvitb forests. Although the number of deposits 

 under exploitation is gradually increasing, still the yield of gold remains very limited. 



The following data refer to the Yerkhneoudinsk region. 



The gold workings belonging to the system of the rive)- Lena are situated in the regions 

 of Yerkholensk and Ivirensk in the government of Irkutsk, in the region of Bargouzinsk in 

 the Transbaikal province and in the region of Olekminsk in the province of Y^akutsk. Although 

 the upper courses of the Lena abound in gold deposits, they are generally poor, 

 and therefore the number of deposits under exploitation and the amount of gold produced in the 

 Yerkholensk and Kirensk regions is inconsiderable. The gold workings of the Bargouzinsk 

 region are situated to the east of Lake Baikal along the upper courses of the river ^'itima
