284 THE PIC'TOU COAL FIELD — POOLE. 



Under approximately similar conditions the Sprini^ Hill basin 

 is found in Cumberland County, and between this point and the 

 Pictou field lie other and subordinate deposits of the coal meas- 

 ures, in all cases on the flanks of the metamorphic rocks, so that 

 it would appear further discoveries of workable seams will, if 

 ever, in all probability be made along this range of country. 



Elsewhere in some detail reference will be made to the changes 

 found to occur in beds of the same horizon as they are traced 

 across the country, and from the data obtained doubts have arisen 

 whether the field of deposition was very much larger than that 

 which now remains. In fact the disposition is rather to consider 

 the Pictou field with features distinctive from those of the other 

 fields of Nova Scotia as an isolated deposit cut off" from the broad 

 seas that left such extensive records around the shores of Cape 

 Breton of luxurious plant life in Carboniferous times. 



In treating of the coal measures those of this field may con- 

 veniently be divided into separate portions having the following 

 limits : — 



The Westville Section ; to include all the coal bearing strata 

 lying west of McCuUoch's brook and Water's hill ; 



The Albion Section; succeeding to the eastward as far as the 

 Interco'onial Railway bridge and the mouth of Potter's brook ; 



The Potter's Brook Section ; from the points mentioned on the 

 East river to the town of Ne^T Glasgow ; 



The Fraser Adit Section ; lying eastward of New Glasgow,, 

 and the last-named section ; 



The McLellans Brook Section ; an overlying extension east- 

 ward of the Albion ; 



The Marsh Pit Section ; the further continuation of the series 

 upwards including the highest in the Middle Coal Formation. 

 The rocks of this section are in part repeated in the subordinate 

 syncline which may be styled 



TIlc Yale Section ; which takes in the most eastwardly lying por- 

 tion of the field and its extension westward on the flanks of the 

 McLellan's mountain to McLellan's brook forms
