THE PICTOU COAL FIELD — POOLE. 31 T 



inclination is light, 9° to 12°, and the series tliat are spread out 

 along- the winding course, are crowded into half the distance be- 

 tween Irishtown and the grist mill bj- the steeper dip that there 

 prevails. 



The oil coal of Patrick's pit on McLellan's brook was one foot 

 thick at the crop, but decreased to seven and a half inches at 70 

 feet down the slope, which had a course N. 45, E. 30°. The second 

 working dipped N. 20, E. 29\ and at 150 yards to the north the 

 direction changed to S 20, E. 25°. No change in the structure 

 of this locality as described in the report is now suggested, the 

 only note that n)ay be added being to suppose that the three feet 

 seam, behind which the Fulling mill fault no doubt runs close by, 

 is one of the Widow Chisholm group of small seams crossed lower 

 down by McLellan's brook. Of the actual thickness and value 

 of this seam nothing definite now seems to be known. 



The anticline at Black's mill site, which was made plain by the 

 exposures along the adjoining Sherbrooke road, is also indicated 

 by the diverging dips seen in the small lateral water course from 

 the north that joins McLellan's brook just west of G. Walker's. 

 Where the culvert of the Vale railway passes over it an increased 

 dip shews a slight fault, or it may be only a local squeeze similar 

 to those seen on the right bank of the brook some 200 yards 

 above the old Mill dam which is now washed awa}^ There the 

 strata take the form of small basins with local dips nearly verti- 

 cal, and deflected from an easterly to nearly a southerly direction. 

 The irregularity is only local, for the influence of the squeeze 

 does not extend to the left bank of the stream. 



Logan gives the major part of this section in detail, the deep 

 ravine through which the brook flows furnishing exceptional 

 opportunity for studj^ No dislocations of moment are met with ; 

 the small faults cut in east levels of the Foord pit are for the 

 present obscured by a land slide, but the disturbances at the 

 mouth of Marsh brook and higher up at the oil coal pit are 

 plainly to be seen. No check measurements of the section have 

 been made as it is evidentl}' barren of workable coal, except of 

 the Marsh pit portion by borehole which gave the following- 

 record : —
