Beneath these rocks lie the coals (including clay masses) of the 

 cliffs to the east of the Great Glace Bay bar ; which I propose to 

 give at another time, in connection with a survey of the coast line 

 eastward. 



A few notes to the above section are needful, as follows : 



(a.) These rocks cap the square headland projecting into the Gulf of St. 

 Lawrence between the Burnt Head and Little Glace Bay. They are the high- 

 est coal-measure rocks of this basin, and perhaps the highest coal-measures 

 south of Sydney Bay. The cliffs are about forty feet high, and exhibit a 

 remarkable contour, caricaturing the hftraan face in profile, by means of 

 the overhanging ledge of hard sand rock at the bottom of the mass, and 

 about halfway of the height of the cliff. See wood-cut (a). 



(b.) The upper part of this clay is crowded with small nodules of iron, 

 (c.) Ranging for a great distance along the cliffs. Stripping it would 

 yield a large quantity of good ore. The plate varies from 4 to 8 inches, 

 (d.d.) These streaks are not coal, although they resemble it at a distance, 

 (e.) These shales vary in compactness, but form essentially a homo- 

 geneous mass of finely levigated and foliated sandy mud, the top rock of 

 the great coal. 



(f.) Of this, only six feet is good workable coal, on the coast, but it in- 

 creases westward, and with the omission of eighteen inches poorer top coal, 

 yields from six to seven feet of good body coal. 



(g.) This mass of building stone is a rare exhibition for these coal-mea- 

 sures. It forms the long point on which the pier is built. Its thickness 

 could not be exactly determined, because like all the very sandy deposits 

 of the section, it is false-bedded and variable. The great sand-rocks un- 

 derlie all the productive coal-measures, and are seen around Sydney. 



(h.) A coal shale, compactly foliated, highly bituminous, burning well, 

 but with much ash, and crowded with fish-scales and minute shells. It 

 sometimes reads thus : Cannel, S inches ; Bituminous coal, 8 inches ; Clay, 

 li inch ; Bituminous coal, 3 inches. 



(i.) Here comes in a jet-black slate, growing compact like cannel, but
