¥nZeSi. Burmis— Altitude 3,995 ft. (1,217-6 m.). 

 (fromDunmore)Burmis Station is almost exactly on the line 

 187-6 m. of a great fault, the strike of which coincides 

 301 -g km. closely with that of the rocks and is nearly north 

 and south, the railway crossing it approximately 

 at right angles. To the east of the station, on 

 the north side, can be seen a series of light- 

 coloured, soft, crumbly, and in places shaly, 

 sandstones, the exact age of which has not been 

 as yet definetely determined,, but is probably 

 well up in the Cretaceous. The fault with its 

 easterly downthrow has brought these rocks 

 against the Kootenay formation showing a 

 throw of at least 7,000 feet (2,133 rn.). 



A short way to the west of the station, 

 Kootenay rocks are fairly well exposed on the 

 north side of the track consisting of hard, 

 light-coloured and dark grey sandstones, grey 

 and black shales, and coal seams, the latter 

 being overlaid by a massive bed of very hard, 

 light-weathering, siliceous sandstone, in places 

 conglomeratic, which constitutes the top of the 

 Kootenay. The whole of the Kcotenay, usually 

 from 650 to 700 feet (198 to 213) in thick- 

 ness (1.), is not shown here, its base, together 

 with the Fernie shales, having been cut off 

 by the fault. In the vicinity of the fault 

 the Kootenay rocks are quite severely folded, 

 good exposures illustrating this are to be 

 seen near the Davenport Coal Company's 

 tipple. 



The Davenport Coal Company has developed 

 six coal seams here, the several thicknesses of 

 which are 3-4 feet (i -o m.), 5 feet (i -5 m.), 4-6 

 feet (1-4 m.), 5 feet (1-5 m.), 6 feet (i-8 m.), 

 and 6 feet (i -8 m.). The coal is mined by pillar 

 and stall method and hauled to the tipple by 

 endless rope; the steel tipple is equipped with 

 Marcus screens, built at Newcastle-on-Tyne, 

 and is capable of handling 120 tons per hour.
