THE PICTOU COAL FIELD — POOLE. 287 



can be judg-ed from the extent to which they have been exposed, 

 tliey increase in strength as they pass northward. It will further 

 be noted that their approximate beginnings coinciding witli a 

 deterioration of the seam make a line roughly parallel to the 

 North fault, and it has hence been assumed that this series are 

 laterals of the Fletcher fault. It is almost certain that the 

 southern dip of the measures on the brook at the Drummond 

 railwa}^ bridge does not continue far to the west of the brook 

 or across the position assumed for the great fault, the probability 

 being that the Black Diamond series of faults carry the measures 

 of the Wcstville section with an easterly dip up to the Fletcher 

 fault or with a flexure if any to the north as they approach it. 

 Positive proof of any one contention respecting these overlying 

 measures and the lay of the northern portion of the section 

 cannot readily be had, the surface cover being deep, 60 and 80 

 feet have been met with, and natural exposures are few. 



Of the measures underlying the main or Acadia seam sections 

 were obtained by boreholes and trial pits in the neiglibourhood of 

 the collieries. The records of the former are given below but of 

 the latter details are not now available. The Scott pit, a sink- 

 ing to the second scam close to the Drummond slope, gives 

 between the seams dipping at an inclination of 16° a depth in 

 the shaft of 230 feet, no compact sandstone being met with as 

 in the same zone in the Black Diamond area at a spot only one 

 mile to the northward. In the same locality, the anticlinal of 

 Hartley, a third seam and a fourth seam have been found but 

 the quality of the two latter has not warranted further explora- 

 tions on them. 



Mr. Fergie, the manager of the Drummond Mines, kindly sup- 

 plies the following section of the second seam at a distance of 

 1800 feet down the slope below the bottom of the Scott pit : —
