THE PICTOU COAL FIELD — POOLE. 285 



The Mountain Sectiov, and completes the area so far as is 

 known of these deposits. 



Westuille ISection ; — This inchides the area occupied by the 

 Acadia and underlying coal seams ; it extends from the North 

 fault near Alma to the Culton adit, and from Westville to 

 McCulloch's brook. It includes the Bear creek synclinal of 

 Hartley/^) who considered this portion to have a depth only of 

 800 or 900 feet from the surface to the Acadia seam. Further 

 working since Mr. Hartley's day by the Intercolonial Coal Mining 

 Company shows no characteristics sufficiently marked to w'arrant 

 the continuance of this division of the section. In fact it will be 

 seen on the map that the line of levels in the range of pit 

 workings at a depth of 1,000 feet is practically straight across 

 the three areas for a distance of nearly three miles. At a lesser 

 depth the deflections in the levels in the southern limits of the 

 Intercolonial Coal Mining Company's w^orkings (the Drummond 

 mine) are due to faults, downthrows to the east, the influence of 

 which brings the Acadia seam to the surface at Culton's adit. 

 From data obtained in mining it appears that a dislocation having 

 a throw of 200 feet passes in front of this adit, and it is one of 

 the Drummond series of faults elsewhere referred to. 



In this neighbourhood the dip of the strata is about 10" in- 

 creased to 22° at the south-east corner of the Acadia Coal 

 Company's area, to 30° when the north side line of the latter 

 area is crossed by the same level, to 45^ at the further end of the 

 levels in the Black Diamond area, to 46° where the seam crops 

 out on the Middle river at French's tunnel, and to 60° where 

 measures believed to be the equivalent of the Acadia seam, 

 greatly reduced and deteriorated, show on Brown's brook on the 

 west side of the Middle river close to the contact with the New 

 Glasgow conglomerate Along the crop of the Acadia seam the 

 dip at the Drummond slope is 16°, at the Acadia slope 24°, and 

 at the Black Diamond slope 28"^. Follow^ing the dip in a course 

 at right angles to that just given and taking for a midway line 

 the Acadia slope, at the surface the inclination is 24° increased 

 at 1600 feet distant to 26° and at 3600 feet to 27^. This latter
