THE CENTRAL RANGE MINES. 395 



conforms to the general strike and dip directions. It carries good 

 values in wolfram for a vertical distance of some 100 feet above 

 the road, but below this level an exploratory drive yielded only 

 a little molybdenite. On the South Hill section, the part to the 

 south of the road, the veins are thinner and strike from 5° to -10° 

 west of north, east of south, the general dip being about 65° towards 

 the east. The veins themselves are in granite, but the sediments 

 come in on the lower flanks of the hill. 



Wagon \'<>nh. Thitkaichaung, and Rubber Mile. -These mines 

 are situated on the Kyaukmedaung ridge, which crosses the main 

 Siam road at mile 25, and from that point runs northwards for some 

 four miles through the concessions, and more or less parallel to the 

 main Central Range, The crest of the ridge is about 2.000 feet 

 above sea level and it is built up of typical sedimentary rocks in 

 which slates and argillites predominate. In the Rubber Mile area, 

 a small patch of altered granite comes to the surface and it is pro- 

 bable that the mineral-bearing veins owe their origin to this under- 

 lying granite, which may be connected underground with the main 

 mass some two miles away. The workings of Wagon North arc 

 on the steep western scarp and those of the other two mines on its 

 eastern Bide.
