THE CARBONIFEROUS SYSTEM. 



O 



possibly a gap on the north, as represented on the sketch-map (Fig. 

 135), which I must, however, remark is merely an attempt to reduce 

 to order complexities not as yet fully intelligible. The relations of 

 this trough to the rocks to the northward we shall leave until we have 

 attempted to trace the synclinal in its extension to the East.

Coal Areas.— (I) General Mining Association, or Albion 

 Mines ; (2 and 4) Acadia ; (3) Nova Scotia or French's ; 

 (5) Intercolonial or Bear Creek; (6) Montreal and Pic- 

 tou or Haliburton's; (7) German Company, and others; 

 (8) Sutherland's River; (9) New Glasgow or Kirby's. 



At the date of the publication of the first edition of "Acadian Geology," 

 '-'little was known of the extension of the Albion Coal measures to the 

 eastward of the East River. I could at that time only indicate the 

 occurrence of Coal measures with a dip showing a considerable fold 

 or bend of the measures in M'Lellan's Brook, and the probable exten- 

 sion of the productive Coal measures in the direction of Merigomish. 

 Subsequent observations by Mr Poole threw additional light on the 

 bend of the measures, and more recently several discoveries of coal 

 have been made, and I have seen, through the kindness of Mr Moore 

 of Montreal, plans prepared by Mr Barnes of Halifax which appear to 

 me approximately to establish the true distribution of the beds.
