THE PICTOU COAL FIELD— POOLE. 245 



the southward for about a mile, the line of contact then brings 

 the Millstone Grit, dipping westward, against the Coal Measures, 

 which dip at a light angle to the north-east. 



The termination of the McCulloch brook fault to the south 

 has not been made out, possibly it is cut off by the Drummond 

 series of disturbances, which seem to increase rapidly in strength 

 as they pass to the south-east, and limit the southern margin of 

 the Westville section. To the north this fault was mven a di- 

 rection towards Smokytown, but now it is assumed to be 

 deflected more to the north, with a course parallel to the Black 

 Diamond series, and to the faults exposed in the deep workings 

 of the Acadia pit, and to terminate against the heavy Fletcher 

 fault. 



Fletcher fault : — This fault, though a large one, and presenting 

 facilities for examination seldom met with, does not seem 

 to have been noticed by Mr. Hartley. It crosses McCulloch's 

 brook, 16 chains below the Drunnnond railway bridge, and di- 

 vides red and grey rocks, dipping at a light angle to the north- 

 ward from the Coal Measures, dipping south, S. 40'-', E. 13", and 

 shewing at the bridge a small seam of coal which Mr. Hartley 

 assumed to be the Three and a Half Feet Seam of the Albion 

 section. It hades to the north with a width of 130 feet, and in- 

 verts the lowest of the strata it disturbs. The age of these red 

 and grey rocks is in dispute, in turn they have been relegated to 

 several zones : they are barren, carry thin beds of grey con- 

 glomerate, coarse grits, and sandstones l;)lotched with red and 

 pink stains, besides beds of soft, red argillites. The present dis- 

 position is to consider them as Upper Coal Measures. 



McAdams cut fattlt : — This fault occupies the crest of the 

 anticline in the Albion section, parallel to McCulloch's brook 

 fault, which it in part relieves. It begins near the south line of 

 the Albion area, and increases in strength as it passes to the 

 south. Where it is exposed on the railway, the map of 1869 

 shewed the imaginary extension of the McLeod fault to pass, on 

 an east and west course. 



Dalhousie jnt fault : — This is seen in the workings of the 

 Main, Deep, Third, and McGregor seams. It begins near the line
