[Communicated by Sir C. LyeU, V.P.G.S.] 



The Coal-measures of the Albion Mines present some features very 

 different from those observed in other parts of the coal-formation in 

 Nova Scotia. This must be very e\-ident to any one who compares 

 the published sections and descriptions of the coal-measures of the 

 South Joggins and Sydney*, and those of the Piqtou coal-field by 

 Mr. Logan, Sir C. Lyell, and Mr. Dawsonf . Unfortunately the 

 natural sections at Pictou are so imperfect, that the order of succes- 

 sion of the beds is much less fully known than at the other places 

 referred to. Recent exploratory works, conducted by Mr. Poole, 

 Superintendent of the Albion Mines, have, however, brought out 

 some important facts which are exhibited in the Plan;}; and sectional 

 lists appended to this paper, to which these remarks relate, and with 

 the aid of which I propose to state the more important points in 

 which the Albion measures differ from the rocks of similar age in their 

 vicinity, and, if possible, to indicate the causes of these differences. 



1. The coal of the Albion Mines is somewhat peculiar in its 

 structure and chemical composition. It is more highly laminated, 

 abounds more in mineral charcoal, is more bituminous and much 

 more free from sulphuret of iron, than the coals of other parts of
