GILPIX CARBOTsUFEROUS DISTRICT OF ST. GEORGE's BAY. 359 



overlaid by the unconformable carboniferous, -whose dip is to the 

 north-east, but at an easy angle. In the clifF close to the point of 

 contact are seen signs of an upheaval of unknown extent ; a little 

 further to the north is another of about fifty feet, followed by three 

 more wath from twenty to forty feet of dislocation. The strata are 

 red and brown sandstones with beds of black shale ; the force of 

 the upthrow has carried the latter through the lighter coloured 

 stones, so that the lines of fault are marked on the cliiF in narrow 

 gores of black pulverized shale. 



From this point to the head of the Bay are frequent exposures 

 of the Low^er Carboniferous, in many places disturbed, but with a 

 general dip to the south-east. As the strike of the beds approaches 

 to a parallelism wdth the shore, measures are made slowly, so much 

 so that opposite St. George's Town, a distance of fifty miles, we 

 still find beds of conglomerate, whose warm color recalls their 

 counterparts when of triassic age. A clear idea of the measures of 

 the district can be obtained by ascending the Barasois River, which 

 pursues a general south-east course towards the interior. At its 

 mouth is a large cliff of red sandstone, succeeded by their limestones 

 and conglomerates ; about three miles from salt-water the river has 

 cut its w^ay through an immense bed of gypsum and red marl. 

 Although identification is rendered impossible owing to distance 

 and intervening dislocations, it is probable these deposits are on the 

 same horizon as those of the Codroy Valley. The gypsum crops 

 again five miles to the westward and is exposed on Fissels River 

 ten miles east of this point. A line drawn from the gypsum of 

 Kippens Brook, north side of the Bay, to the mouth of the Codroy 

 River follows closely the line of crop of these beds and furnishes an 

 important key to the whole district. Still ascending the River we 

 pass beds of Conglomerate, some of which appear to be repeated by 

 fiiults. In certain of the beds are found larjxe frao-ments of mao-netic 

 iron ore, plainly derivable from the great deposit of black oxide in 

 the older rocks. Gradually they pass into finer grits with beds of 

 sandstone and bluish fireclay. About eight miles from the shore is 

 the crop of a small coal seam in the vertical measures of a fault. 

 The next four miles is through a series of anticlinals Avith signs of 

 many dislocations, pursuing a general north-east and south-west
