268 THE PICTOU COAL FIELD — POOLE. 



few points are in situ and in line They indicate equally with 

 the regularity of the overlying conglomerate the absence of 

 serious north and south dislocations passing through this part of" 

 the country. This rock is unknown west* of the East river and 

 to the south of the North fault. It is an agglomeration some- 

 tiuies parti-coloured of fragments largely siliceous which on 

 weathering acquires its characteristic black tint. Where shewn 

 on Logan's map near the house of Mr. A. McGregor, the land 

 owner says it has never been quarried, and he is doubtful if it 

 be in position The exposure is very small. But on the side of 

 the telegraph road to Merigomish it is undoubtly undisturbed as 

 also on Pine Tree brook, and on the same course further east in 

 a depression north of the house of Mr. Barton where it 

 stands up above the surface in beds of 20 feet or more in 

 thickness N. 35° E. 25.° The exposures in the brook from the 

 house of Mr. J. Andrew Fraser eastward are described by Logan^ 

 Apparently he failed to notice some 150 yards higher up the 

 brook soft red and grey sandstones dipping directly in the oppo- 

 site direction S. 25" W. 43°, which necessitate an anticlinal or 

 east and west fault intervening between the base of his section 

 and this point. A quick turn of the brook and a bluff marks the 

 change. Forty paces higher up the brook black limestone is 

 seen dipping at a light angle to the eastward and apparently cut 

 off by a fault in sandstone S. 20*^ E. Higher up on a laterial 

 branch, at the house of Mrs. Roy, thin-bedded red and grey rip- 

 ple-marked sandstones resume the northeidy dip, N. 23° E. 75° ; 

 here begins the slope of the higher ground of the range border- 

 ing the North fault, and on following along it at other points 

 similar steep inclinations are to be met with, and fields of very 

 red soil suggest the presence below of the red sandstone and 

 marls elsewhere seen. The direction of the more northerly of 

 tliese high inclinations seems to coincide with the general dip of 

 the strata that succeed at lesser angles in the direction of the 

 conglomerate ridge, while nearer to the North fault the ten- 

 dency of the vertical dips is to the southward. The rocks there
