Mo-hei. However, it is probably the largest and most important 

 producer in this part of Yunnan. 



The important city of P'u-erh Fu, lies at an elevation of 4,500 



feet in a small plain of its own, surrounded 

 Route. by ij mc8 tone hills. Mo-hei is 12 miles to 



the north-east of the city along the main route to the capital. 

 Permo-Carboniferous limestones continue for a few miles and are 

 then followed by typical rocks of the Red Beds series. The 

 road gradually rises, attaining an elevation of 6,200 feet at 8 miles 

 and then descends rapidly into the valley in the bottom of which 

 Mo-hei is built at an elevation of 4/200 feet. 



At one time a salt-mine was worked at old Mo-hei, but it became 



exhausted and the present output comes from 

 Salt-mine and bnne- ft mme opened at new Mo-hei, one mile 



further up stream. There is also a brine- 

 well near the same place. The processes of mining, leaching and 

 boiling are the same as elsewhere. The evaporating sheds, of 

 which there are 28, are large and clean. Each furnace carries 

 24 pans in 6 rows of 4 each. About 300 miners and coolies are 

 employed and the monthly output is 600,000 catties or 334 tons 

 approximately. The salt-boiler receives Tls. 1*1 per 100 catties. 

 The Government selling price is Tls. 4*82 per 100 catties. The 

 Government tax is Tls. 3'20 per 100 catties. 



Salt near Lang-CrTiung Hsien (lat. 26 6': long. 99° 55'). 

 Logan Jack has described the salt works of Chow Ho (Chiao- 

 hou-ching) a small village about 10 miles west of Lang Chiung 

 Hsien, in the following words : — For the first time in China we 

 saw rock-salt, a little dark in colour but fairly pure, and entirely 

 soluble, with the exception of a trifling residue of silica. The 

 rock is sawn into blocks of varying sizes convenient for transport 

 and sale. There are also brine wells, the brine being led down 

 in long conduits from the hillside to evaporation works in the 

 village. The firewood for the furnaces is floated down the river, 

 and caught and stacked at the village above, Chow Ho. (Jack, 

 op. cit.y p. 189). 



The brine-wells of An-ning Chou (lat. 24° 56' : long. 102° 29'). 

 An-ning Chou is a small town one day's march to the west of the 

 capital, along the main trade route to Ta-li ¥u. Though now
