244 THE I'lCTOU COAL FIELD— POOLE. 



The Survey map shews this fault to cross east of the west 

 corner of the Albion area, but explorations in 1860 traced the 

 Albion measures 5 chains west of the corner and in a trial pit, 

 that got coal at this point, a fault was met with, and in another 

 pit to the rise of it a borehole was continued after coal was got 

 at 82 feet ; at 40 feet the rods dropped 5 feet, and water drained 

 away from the pit for a time. These trial pits would appear to 

 be close to the fault. In them the measures dipped N. 10" E. 18°,* 

 while a trial pit sunk in 1884, 12 chains further to the west> 

 found the inclination below 65 feet of clay, N. 69"" E. 26°, in 

 strata of the Westville section, on the west side of the fault. 



Other trial pits and boreholes were put down in 1860, south of 

 the corner, but dropping into 40 and 50 feet of clay they were 

 abandoned, and tracing the measures to the westward was 

 stopped. Again in 1889 explorations made in this neighbourhood 

 and to the northward found on the western side of the now as- 

 sumed position of the fault, the till to be compact and uniform 

 to the depths attained by the trial pits. This was not the case 

 to the eastward of that line, where the rock w^as met within ten 

 or fifteen feet of the surface. 



Mr. Hartley estimated this fault at IGOO feet, but the proved 

 inclination of the Acadia main seam, and later explorations along 

 the western margin of the brook make it probable that a disloca- 

 tion of 2600 feet is more neai'ly correct. 



On approaching this fault from the eastward it is not found 

 to produce a deflection of the measures within the Albion Lease ; 

 but it is otherwise immediately south of that area, and a folding 

 back of the strata rapidly increases as the brook is followed up 

 to the railway culvert. This deflection makes an anticline which 

 is exposed by the railway at its highest point, Mc Adam's cut; 

 and its influence is noticed in the workings of the several seams 

 of coal at depths below where the surface shows no indications. 

 It is accompanied by a thinning of the strata intervening be- 

 tween the seams, a feature that will be again referred to in 

 treating of the Albion section. Continuing along the fault to
