312 THE PICTOU COAL FIELD — POOLE. 



as they approacli Chapel knoll, and either dislocate it or butt 

 against its southern steep slopes. In the absence of positive 

 knowledge it is impossible to estimate the relative horizon with 

 the Foord pit section of the lowest exposures on the river bank, 

 east side, of the Chisholm's pond section given on pages 47 and 

 48 of the Report. 



The syncline to the north of the Foord pit that opens out 

 round the western end of Chapel knoll may be regarded as the 

 southern fork of the main syncline that passes westward to the 

 south of D. Tupper's, a northern fork passing north of the knoll 

 towards the iron Railway bridge over the East river. The 

 bottom of the syncline was proved in Muir's slants 92 feet below 

 the Foord pit levels, and also further west where the levels 

 turned round ovei' a ridge running north and south that crosses 

 and elevates the bottom of the syncline. The lidge is the termi- 

 nation of a fault that comes from the 'northern rim of the field. 

 The position of the bottom of the basin is again shown east of 

 Tupper's by the low dips in Jones' brook that flows by the 

 Chapel ; and its northern upheave is seen higher up the brook. 

 How far east the northern fork extends has not been made out 

 but it seems to be represented in part by the Bridge fault and 

 change of dip that evidently passes between the Stewart and 

 Richardson seams across the river. 



Between Tupper's and the river lies a tract of country 

 indifferently known. It has been explored but the exposures 

 have done little to disclose the structure. The Survey dots in 

 possible lines of crop and mentions the sinking of the Haliburton 

 pit and other exposures. North of Tupper's, Fraser Ogg's 

 quarry furnishes a fine white close-grained sandstone that ex- 

 tends at least 1400 feet and dips N. 10"^ E. 8°. This strip it may 

 be noted lies on high ground immediately north of the dis- 

 trict at Tupper's which is bounded by faults known in the 

 Foord pit workings to dip in opposite directions, and from 

 which it is dissevered by cross faults. 



The next exposures eastward are those mentioned in page 

 82 referring to the southeast corner of the Sutherland area and 

 the Halitiurton pit, page 105, in the Montreal and Pictou area.
