Kilometres which lie to the south. The fault is marked by 

 a wide shear zone, with slickensided walls, some 

 of which may be seen in the cuts south of 

 the track. 

 6i-8m. Goldstream — Alt. 280 ft. (85 m.). From 



99-5 km. Goldstream to Colwood, the railroad crosses the 

 terraced Colwood delta. To the north of the 

 track is Langford lake in one of the un- 

 drained hollows of the delta, possibly an 

 ice-blcck hole. To the east of Langford lake 

 is a gravel pit, where the coarse, horizontally 

 bedded top-set beds are well exposed, resting 

 on the finer, cross and steeply bedded fore-set 

 beds. The gravel is used for railroad ballast. 

 64-6 m. Colwood — Altitude 246 ft. (75 m.). To the 



104-0 km. east of Colwood, the railroad descends from the 

 delta nearly to sea level, cutting through the 

 Vancouver volcanics, Sutton limestone lentils, 

 and small intrusive masses of Wark gabbro- 

 diorite gneiss and Colquitz quartz-diorite gneiss. 

 To the north of the track, a mile beyond 

 Colwood, is the plant of the Silica Brick Com- 

 pany. Limestone is quarried south of the 

 track, elevated over the track, and burned 

 in down draft kilns. The resulting lime is 

 hydrated and used in the manufacture of 

 sandstone brick, the sand being obtained north 

 of the track from the fore-set beds of the 

 Colwood delta. 

 66-8 m. Parsons Bridge — Altitude 99 ft. (30 m.). 



107-5 km. From Parsons Bridge to Victoria, the railroad 

 traverses the southeast lowland of Vancouver 

 island. This portion of the lowland is largely 

 covered by Maywood (inter-glacial) clays with 

 in places a thin mantle of Vashon drift, but 

 with numerous small monadnocks or ledges 

 of the crystalline rocks, Vancouver volcanics, 

 Sutton limestones, and Wark and Colquitz 

 gneisses. Three quarters of a mile east of 

 Parsons Bridge is a limestone lens that has 

 been quarried for flux by the Tyee Copper 

 Company. 

 68-8 m. Esquimalt — Altitude 35 ft. (11 m.). One 



110-7 km. half a mile north of Esquimalt the railroad runs
