THE PICTOU COAL FIELD— POOLE. 263^ 



llections in the direction of the dip but with a general strike S. 

 5"^ E. Among them a bed of grey conglomerate which crosses the 

 river and abuts against the older series on the right bank. On th& 

 line of contact a few inches of soft and broken " gouge " separate 

 the horizontal carboniferous from the vertical older rocks, through 

 which the river has cut a bed 200 feet wide with walls of 20 ta 

 40 feet in height before entering the coal basin. Exposures of 

 other strata below this bed of conglomerate shew on the western 

 side basal beds of conglomerate resting unconformably on the 

 steeply inclined Fishpool rocks. The whole series of the Mill- 

 stone Grit thus exposed on the East river give to it a total thick- 

 ness of only some 900 feet. 



On the eastern bank and succeeding in ascending order ex- 

 posures are few. The overlying beds at Plymouth while having 

 the same strike as the Coal Measures of which they appear to be 

 continuations are in some cases i"ed in colour, and they are asso- 

 ciated witli a grey conglomerate about five feet thick at Eraser's 

 quarry where the dip is due E. 19*^. This conglomerate does not- 

 shew further northward in the coal field in what is assured to be 

 the same horizon, although it probably can be traced southward 

 to the foot of the hills. 



On the abandoned branch railway of the Drummond mine 

 which joins the Intercolonial railwaj^ near the county asylum,, 

 on that part which overlooks the valley of McCulloch's brook,, 

 exposures shew a dip S. 85° W. 82°, and on the east side of the 

 ridge where a small brook on Alex. Culton's farm crosses, dips. 

 N. 5*^ E. 18°, are seen. Higher up this brook the dip is round 

 to N. 40'^ W. 38°, thus giving to the tongue of Millstone Grit 

 that lies east of the southern part of the Westville section the 

 general form of an anticlinal having a broad base resting against 

 the upper Fishpool beds of McKay's brook.* 



* In the Trans. Vol. IV, pajre 92, referring- to this ground here classed as Millstone Grit, 

 Mr. Gilpin says " Between these faults (the theoretical McLeod and South faults) no measures of 

 an age older than the productive are known to exist, and the coal strata with everj' appearance of 

 reason considered to run across this intervale without undergoinjf disturbance," and again, page 92, 

 "Enough to show that the synclinal form is preserved from the Bear Creek (the Drummond mine) 

 area to the McLcod seam * * * a district one and a half miles wide yet unexplored, and * « * 

 would allow of a development little if at all inferior to that attained by the seams of the middle or 

 Albion synclinal " p. 97.
