308 THE PICTOU COAL FIELD — POOLE. 



of Potter's brook fault ; followed eastward in regular course with 



the underlying coal seams, it is seen in two laterals of McLellan's 



brook, where it was also opened in 1860, and again where it 



crossed McLellan's brook, just below the mouth of Steep brook. 



This last exposure gives this section : —

Here the dip is S. 70, E. lO'', but further south where the high- 

 way to McLellan's mountain crosses Steep brook it is inci'eased 

 to 26°. 



Whether this band is an extension of the so-called 8' 6" seam 

 or a closely underlying bed is not now clear, its value lies in 

 showing the unbroken character of this central portion of the 

 held. 



Returning to the starting point and going westward the nor- 

 thern dip of this seam is not known. But at a lower horizon 

 near the Colin pits a three and a half foot seam overlies the 

 Albion quarry sandstone, dipping N. 45, E. 24°. '^'It has been 

 traced to the westwara, and is probably the same as that opened 

 on a branch of McCulloch brook near where the Truro road 

 crosses the latter stream, but it seems to have thinned out with 

 the sandstones and disappeared to the eastward for it Avas not 

 cut as it otherwise would have been in sinking the Foord pit. 

 The first exposure of coal west of the Foord pit is on the side 

 of the Truro road near D. Tupper's house, where this seam, 5 

 feet thick, dipping S. 17, W. 35°, was opened. This seam is 

 believed to be repeated westward 700 fee.- at a small brook 

 where it is on edge, on a line that corresponds with a fault found 

 in the Foord pit workings beneath. Southwest from here by 

 the brook on the south side of the road the same seam is seen 

 dipping S. 20, W. 48*^, and although the opposite dip is south 

 within 400 feet of the spot the coal is not found on the upheave- 

 It is underlaid by a series of sandstones and overlaid by black
