328 THE PICTOU COAL FIELD — PO(JLE. 



measures are supposed to be repeated in the Mountain section 

 with an inclination that ao-jiin hrino-s in tlie highest members of 

 the Marsli pit syncline. 



The Survey map f^ives the Potter brook fault as passinij to the 

 north of the Marsh pit, and a fault or series of troubles probably 

 does pass Ijetween the pit and the northern upheave of the group, 

 but its course is assumed to differ somewhat and to parallel the east- 

 erlystrike of the measures which extend toD.McPherson's. Faulty 

 ground is indicated by the dislocation met with in the slope 

 referred to in page 27 sunk for the Merigonish Company, where 

 the dip is given as S. 3 W. 17*^, increased by a fault at 80 feet 

 down the slope to 22°. Behind this slope a borehole was put 

 down in 1889 for some 300 feet, but the inclination was found too 

 high to encourage furthur exploration. Eastward of this point 

 in the small brook, McPherson's, referred to on page 28, late 

 openings have been made in both the Captain and George McKay 

 seams, but in both cases only 2' 6" cf coal was found lying at a 

 steep angle, 45". It is worth}^ of note that an extension of the 

 strike of these steep measures into the Section of Pine Tree meets 

 a series of vertical dips parallel to the escarpment of New Glas- 

 gow conglomerate, and leaves all the known exposures of black 

 agglomerate limestone to the north. The 10-inch seam overlying 

 the Captain seam some 200 feet has not again been opened, but 

 in the flat ground at the head of the pond the tvash of a good 

 coal has been lately discovered in a line with the crop of the 

 seam on Marsh brook described at the head of page 29. This 

 seam also has been examined and found to dip to the west at a 

 low angle, and to yield only 8 inches of good coal. It is suc- 

 ceeded 100 yards higher up Marsh brook by sandstone beds that 

 dip 3° in the opposite direction. 



Eastward of McPherson's brook the coal seams have not been 

 followed, but a grey conglomerate is met in that direction, and in 

 the brook that cuts the northeast lease line on its way to Pine 

 Tree sandstones dipping northward are exposed ; a change in 

 direction that indicates proximity to the great North fault. 



Boreholes Nos. 2 and 3 of the Acadia Company referred to in 

 the preceding section were put down in the Pictou area in 1-^78.
