In the Millstone grit, consisting of two synclines, and underlying the 

 Coal Measures to the west of Sydney Harbor, no workable seams of 

 coal have been discovered. The rocks consist mainly of greenish gray 

 and white pebbly sandstone, sometimes falsely bedded with small areas 

 of conglomerate containing Catamites and other plants. 



Mr. L. W. Bailey and Mr. R. W. Ells, 1 in 1878, reported on the Car- 

 boniferous belt of Albert and Westmoreland Counties, New Brunswick. 



The formations of this area are divided as follows : 



1. Metaruorphic rocks of pre-Carboniferous age with intrusive syenite. 



2. Lower Carboniferous formation, including the " Albert sbales." 



3. Millstone grit, formation, or lower member of the Carboniferous system. 



The u Lower Carboniferous rocks " of Albert County are but the ex- 

 tension of those in Kings County, where they are followed by patches of 

 unconformable gray-rock of the Millstone grit series. The section in 

 Albert County consists of: (1) The " Basal Conglomerate," which is 

 sometimes wanting (thickness unknown) ; (2) calcareous, bituminous 

 shales, including the "Albert shales ;" (3) gray, bituminous, and mi- 

 caceous oil-bearing sandstone ; (4) red and gray argillaceous beds, 

 alternating with conglomerates ; (5) red and gray conglomerate, lime- 

 stone, and gypsum ; total thickness, 1,950 feet. 



Sections are also given from Pollet River, Mapleton, Baltimore, Al- 

 bert mines, Beliveau, and Taylorville, showing the relation of the dif- 

 ferent series and the system of faults. The series of Albert shales 

 bears strong resemblance to the Horton Bluff series in its fossil con- 

 tents, strati graphical arrangement, and rock materials. The general 

 structure of the Albert mine is outlined, with an account of the phys- 

 ical and chemical characters of albertite, and the proofs given of the 

 vein structure of the Albert mine. 



The "Millstone grit formation" is recognized by its gray, and rarely 

 pale purple color, and slight dip. It occurs in the southern part of 

 Albert County, running parallel to the metamorphic hills, and showing 

 evidence of denudation, even before the deposition of the succeeding 

 strata. The gypsum beds, which are quite extensive and pure, vary 

 in thickness from 30 to 50 feet. 



Mr. Hugh Fletcher, 2 in 1878, grouped the rocks of Victoria, Cape Bre- 

 ton, and Richmond Counties in the following manner: 



L . . (1. Syenitic, gneissoid, and other feldspathic rocks. 



* ( 2. George River limestones. 

 3. Lower Silurian rocks. 



S4. Carboniferous rocks. 

 5. Carboniferous limestone. 

 6. Millstone 1 grit.
