Tlie bull ilijposits, P'pre.si'nting the transili(jii lu liKnMinK' ut-jiosit, where the brine is 

 extracted from excavations or \v<;ll.s diij,' in the bottom of salt lakes, occur in the* Yeniseisk 

 f^fQveniriK'iii, at the following works: 1. Abakansk in the Minousiusk district, 25 versts from 

 iIk! Biilzlia iiliis, the depth of the wells upon the bottom of the lake is 9 feet, the strL'ngth 

 of the brine 9 — 13" IJonie; 2. Altaisk, on the left bank of the Yenisei bt.-tween the rivers 

 ]']rba and while Ins, now abandoned, tin; lake having concentrated too much bitter salts; 

 3. j\Ianzinsk, depth of wells 12 f'-et, strength of brine f;" ]>onie. The total production of these 

 mini's in 1891 did not exceed 93,800 ponds. 



Besides the lakes mentioned, in which the cooperation of common salt is now estab- 

 lislied, the Yeniseisk governnient also contains a nuniber of lakes with bitter salts, among 

 wliieh that of j\Iinnsinsk from its extent, 2V'4 s<[uare veists, and the quantity of salt containe-ii 

 in it belongs to tli(! most considerable bitter lakes of Eastern Siberia. Formerly, up to 1877, 

 salt was deposited by natural (,'vaiioration in tie' Minousin.-k lake, allhoiiLdi with a certain 

 intermission, and with it ahnnst the whole ivjjioii of that name was supplied, there being then 

 no salt works. 



In llic Yakutsk borderland, rock salt oeciiis in three spots of the Yiluisk district of the 

 Yakutsk territory, along Ihc light tiibiitaries of the river Yilui. On the right bank of the 

 river Kempendzai the deposit of rock salt forms a bed about 150 sagencs in length and 50 

 in Ihiekiioss. The salt is contained in icd clay and is everywhere accompanied by plaster of 

 Paris partly in crystals, partly in plates of white or greenish hue. In some places the projecting 

 rocks of salt attain a height of 25 sagenes; it is ordinarily white, although pieces of a rose 

 colour occur. On the right bank of the river Kiundai not far from the lake Sikai-Sian, rock 

 salt forms two masses in a mountain also consisting of red clay and gjTJSum. Finally, upon 

 the right bank of the small stream Tabasyngda, a tributary of the river Tongo, also in red 

 clay, at a depth of SV^ feet, lies rock salt of a dirty colour. During the spring inundations 

 this salt is washed out of the banks in such quantities that the water in the stream acquires 

 a brackish taste, as in the river Kempendzai. All three deposits apparently belong to the tertiary 

 system. In the Yiluisk district of the Yakutsk territory, salt is obtained in \\1nter by freezing 

 the brine got from the salt springs of Baginsk on the river Pusty Iri, a left tributary of the 

 Kempendzai, and Kempendzaisk on the river of that name a right tributary of the river Yilui. 

 The strength of the brine reaches 20 to 25 per cent. The springs flow from a mountain 

 probably containing beds of rock salt of tertiary age, judging from the propinquity of the 

 above described deposits of the mineral. In 1891, 2,800 ponds of salt were won from the Ba- 

 ginsk spring and 16,000 from the Kempendzaisk. 



In the Amour Governor-Generalship, salt is evaporated in the Transbaikal territory at 

 the works of Selenginsk in the district of that name, and Kiransk in the Troitskosavsk district 

 on the frontier of Mongolia. There the brine is derived from shafts, 2 to 3 sagenes deep, dug 

 in the bottom of salt lakes. The strength of the brine is 11 to 12° Borne. In 1891, 4,100 pouds 

 of salt were got at the Selenginsk works and 23,300 pouds at those of Kiransk. In the 

 Transbaikal territory occurs also lake Borzinsk where natural deposits of salt take place 

 although not every year; in 1891, 19,800 pouds were extracted. Here must also be mentioned 

 the Doroninsk lakes of the Bargouzinsk district of the Transbaikal territory, in which Glaubers
