2 IS THKliE COAL I'NDEl! I'. E. ISLAND ? POOLE. 



In Prince Edward Island the expectation in tliis direction 

 can only bo met \>y actual search in depth, and tliis may best be 

 done by bore-holes in places careful!}^ selected. Matters h;ive 

 gone so far as to receive attention from the Canadian Geological 

 Survey Department, and an expsrienced ofRcer* has re- 

 visited the Island with that object in view. With tliis feature 

 of the question it is not proposed to deal in this paper, which 

 has for its object only a review of such suggestions as the struc- 

 ture of the several geological formations developed in the 

 neighboui'ing regions seem to present. 



It is no part of this paper to consider the correlation of the 

 several series of deposits both above and below the productive 

 coal measures of Nova Scotia. The terms used are those which 

 appear most convenient, and are the same as those employed, in 

 the Reports of the Geological Survey of Canada, by Mr, Hugh 

 Fletcher in his papers on the surrounding distiMCts. Although 

 disputes have arisen over these terms, and the propriety of their 

 selection has been questioned, they have this advantage, — they 

 leave no doubt as to the sequence of the several groups of strata 

 to which they relate. Whether they be correlatively correct or 

 not, is of no moment in this connection. The terms used are 

 taken to mean as follows : — 



Permian. — Strata chiefly reddish sandstones with a base 

 of conglomerate showing at New Glasgow and else- 

 where ; a few small seams of coal and bituminous shales. 

 The upper members more friable and more easily 

 eroded. 



Coal Measures. — Strata containing workable beds of coal 

 with shales and fireclays chiefl}' black and grey, and 

 sandstones generally grey in colour. 



Millstone Grit. — Strata conformably underlying the pro- 

 ductive measures, including coal seams, and grit often 

 coarse and reddish in colour.
